An image reproduced with varying sizes of halftone dots. These dots fool the eye into thinking it sees different levels of gray or different shades of color. Halftone dots do not show up on computer monitors; only once an image has been output to some type of printer. All printed photographs are halftones.
A QuickDraw GX data structure"also a property of a view port object"that specifies a pattern and a set of colors. A halftone is used to achieve a greater range of colors than may be available on a display device See also: angle, background color, dot color, dot type, frequency, tint type
The process of converting images into a regular array of dots of various sizes with equal spacing between centers. Also the process of reproducing an image as a series of dots of various sizes within a fixed grid.
A photographic process that converts a continuous tone photograph (the kind you get from your camera) into a series of different sized dots that when viewed appear to replicate the original photo. This is the process of printing photographs.
A technique of representing continuous-tone art with a pattern of dots varying in size and angle of placement. The pattern is called a halftone screen. In photographic halftoning, each dot in the halftone screen is called a halftone dot. In digital halftoning, dots in the halftone screen are combined into halftone cells. Black-and-white art is printed using black halftone dots, but color can also be reproduced. Spot color is created by applying a colored ink to a halftone screen. Process color is created by overlaying four halftone screens (one each for cyan, magenta, yellow, and black inks) at different halftone screen angles.
Because laser printers and presses cannot produce gray, the reproduction of a continuous tone image, such as a photo, is processed through a screen that converts the image into dots of various sizes to provide the effect of gray (see linescreen).
A letter pressed or lithographic image reproduced by breaking the image into a collection of pixels or dots.
A method of screening a continuous tone image (like a photograph) for printing or reproduction. The dots in the screen vary in size and density, so as to recreate the complete range of highlights, lowlights, and mid-tones in the original image.
A photograph that has been modified into a dot pattern for printing.
The representation of a continuous-tone image as a series of dots that look like gray tones when printed. Also called a screened halftone because traditionally the original image is photographed through a finely ruled screen, the density of which varies depending on the printer's capabilities. See also AM screening, FM screening, and screening.
A picture or illustration created with solid dots of varying sizes.
A screened photograph. A reproduction of a continuous-tone image in which the tones (highlights and shadows) have been screened into a series of numerous tiny dots of varying size. The halftone is then used to make a printing plate. The variations in size of the dots create the illusion of variations in tone. Light areas have smaller dots and darker areas have larger dots. Traditionally, a halftone was produced by photographing the subject through a fine screen. However, it can be done today electronically. Screens are measured in lines-per-inch (lpi). A screen of 133 lines-per-inch is relatively fine, whereas a screen of 65 is relatively coarse. Fine reproductions require paper of high quality. A halftone is also called a screened halftone or a middletone. Printed photographs are also known as halftones. Artwork that does not have tonal variations, such as cartoons, is termed linecut or line art. Line art is reproduced directly in black-and-white. A silhouette halftone is a haltone with all screen background removed.

A reproduction of a continuous tone image (i.e. a photograph or painting) using fine dots of varying size and spacing to reproduce the shades and textures of the original.
The reproduction of continuous-tone copy (such as a photograph) using a screen to convert the image into dots of various sizes and thereby achieve the variety of tones in the original.
Image reproduced with black dots (spaced close together for dark areas and far apart for light areas) that gives the illusion of a continuous tone print.
A screen pattern of fine dots used to represent a continuous tone.
An image formed by printing close-set dots of varying sizes on paper or other "hard" media.
Term used to designate a contone image which has been prepared for printing using screening technology. This is a pure black/white or full-tone original which uses screening to simulate contones. Georg Meisenbach (1841-1912) is considered the inventor of halftone technology.
A printed picture that uses dots to simulate the tones between light and dark. Because a printing press cannot change the tone of ink, it will only print the ink colour being used on press. This works well for printing text or line art: the press simply puts a full dose of ink for each letter or line on the paper, creating small solid areas of ink. But black-and-white photographs are continuous tone images, and printing a photograph this way would have the same result: large solid areas of ink. White areas of the photograph would have no ink; black areas would have black ink; and grey areas would have black, not grey ink. The halftone mimics the continuous tone of a black-and-white photograph by converting the picture to dots. Photographing a continuous tone image through a screen creates a duplicate image made of dots. Darker areas of the photograph have bigger dots and lighter area of the photograph have smaller dots. To the human eye, the black of the dots blend with the white of the paper to create shades of grey. The result is strikingly similar to the continuous tone of a photograph.
A process whereby gradations of tone in a photograph, drawing, or painting are translated into small dots by being photographed through a glass or contact film screen. The screen simulates the grays produced by commercial printing by reducing tones to a series of dots. These dots vary in size, shape, and spacing in direct proportion to the tones they represent.
A printed image that creates the impression of varying shades of gray as in a photograph by the use of dots of varying size and density.
a pattern of dots of different sizes used to simulate continuous tone photographs.
A printed image composed of dots of varying frequency (number per sq. in.) size or shape, producing tonal gradations.
A photograph of continuous-tones through a screen to convert the image into dots. The result may be either positive or negative and on film or paper.
A halftone image is made up of a series of dots arranged in lines to simulate a continous tone image. To print a continous tone image it has to be broken down into a series of dots. These dots are calles a halftone screen.
a pictorial which has been converted from a continuous tone original image, such as a photograph, into dots of appropriate size which, when printed, give the visual illusion closely resembling the original.
a photograph converted to dots for printing (also see “screen”).
A pattern of dots arranged on an imaginary grid to simulate shades of gray or levels of color. Many printers and all printing presses can not reproduce a CONTINUOUS TONE image; instead, the image is simulated by printing dots of various sizes (the darker the tone, the larger the dots). The pattern of dots is called a "halftone screen." Halftones are specified by how fine the imaginary grid is (and how small the individual dots are). Newspapers are printed with a halftone screen of 85 lines per inch, meaning that the imaginary grid has 85 individual dots per inch; most magazines are printed at 133 lines per inch; most catalogs, 150 lines per inch; high-quality lithographs and artwork can be reproduced at 175, 200, or even 300 lines per inch. Halftones can also be produced with different kinds of dots; the most common halftone screens are made with dots that are shaped like ellipses, but round dots, square dots, line-shaped dots, and other dot patterns can also be used. Color images are reproduced on a printing press by creating a halftone screen for each color of ink, and printing the halftones directly on top of one another in a pattern called a ROSETTE. See also STOCHASTIC SCREEN.
Screening of image with a series of different sized dots to provide the appearance of continuous tone on a printed piece of paper. (See also "LPI" and "continuous tone")

Photograph that has been prepared for single color reproduction.
The reproduction of continuous-tone artwork (such as a photograph) through the application of a screen that converts the image into dots of various sizes. (See the resolution section in the Building Electronic File Module)
Also known as grayscale, refers to the reproduction of shades of gray. 64-level grayscale means the unit scans documents in 64 levels of gray.
A continuous tone image made up of a pattern of dots
Reproduction of continuous tone artwork. A screening process converts the image to dots of various size.
Halftone is an image composed of tiny dots whose variations in size create the illusion of variations in tone. In the past, a halftone screen was used to convert a continuous tone image into a halftone; today, such screening is done electronically.
A light or transparent image that uses a shade of a color rather than its' own separate color.
a photograph used for printing that has been screened to break up the image into dots.
A halftone image is made up of a series of dots rather than a continuous tone. ...
Any photomechanical printing surface or the impression therefrom in which detail and tone values are represented by a series of evenly spaced dots in varying size and shape, varying in direct proportion to the intensity of tones they represent.
A process in which a black-and-white photograph is re-photographed through a screen so that the gradations of light and dark in the original photograph are reproduced as a series of tiny dots that print as a continuous tone. The fineness of the screen is measured in lines per inch, as in a "150-line screen," and is a factor in determining the quality of a printed photo.
A reproduction of a continuous-tone photograph by simulating gradiations of tone using dots of varying size, shape, or proximity.
A method of reproducing continuous tone artwork in print by screening an image to break it down into a series of dots of varying size (which can be reproduced by spots of ink). The size of each dot represents the ink density. Colour halftones are reproduced as a series of CMYK dots laid down in rosette patterns. Halftones are used as printing presses cannot print the fine graduations of ink required for continuous tone.
The process involved when creating an image, using different sized ink dots repeated in a particular pattern.
Pattern of dots of different sizes used to simulate a continuous-tone image in printing, measured in lines per inch (LPI).
A process that will reproduce a continous tone image on a press by splitting up the image into a pattern of dots. The dots vary in size, determining tones or shades.
The process in printing to impart tonal value to a printed piece with a single color of ink, created by separating the different tonal value areas into dots of varying size. This can create a full range from 5% to 95% ink coverage of the paper area to be printed.
A photograph or drawing that has been converted into a pattern of tiny dots. By screening images this way, printing presses can reproduce shades of gray.
The image that results from converting continuous tone images into dots.
The reproduction of continuous-tone artwork through a contact screen. Photographic image formed by a pattern of discrete dot sizes. Dots vary in area and shape but have uniform density. Creates the illusion of continuous tone when seen at a distance.
An image that is converted into a series of different sized dots.
A photoengraving made from an image photographed through a screen and then etched so that the details of the image are reproduced in dots.
A process to reproduce an illustration by photographing it through a fine screen to break it up into dots.
Process used in print for Photographs, paintings, and drawings. Because most printing presses cannot produce continuous tones, images are converted to halftones to simulate continuous tones. Using fine dots of varying size and spacing, halftones can reproduce the shades and textures of the original image.
A halftone is a reproduction in printing of artwork. It has values between 1 and 100% . It can be black and white or color. Halftone is a term left over from the days of the offset camera. Continuous tone photos were shot through a screen to create a "line shot" of a grid of various size dots. Today we still use the word halftone, but the more proper term would be scanned image. The same process happens in scanning- you create a "screened" (DPI) image of what originally had no screen or dots. [Back
The reproduction of continuous-tone images, through a screening process that converts the images into dots of various sizes and equal spacing between centers.
Term describing the varying size and color density of small dots, which serve to simulate the appearance of continuous gradations of tone as found in photographs. Halftones are necessary in order for COMMERCIAL PRINTING to reproduce photographic images. The lightness and darkness of photographic images are reproduced by varying the size and density of printed dots; small dots spaced far apart produce light areas, while large dots clustered more closely together produce dark areas.
A negative or positive image made by photographing an image through a screen so that the detail of the image is reproduced with dots. The reproduction simulates the different tones of the original by transforming them into dots of varying sizes arranged in a grid pattern that has a given frequency. For example, a 150 lines per inch halftone would contain 150 rows and 150 columns of dots (22,500 in a square inch) that could vary in size from zero percent to 100 percent, also called screened negative or screened positive. Halftones can also be generated electronically from digital data.
A reproduction of continuous tone artwork (such as photographs and paintings, including water colors) that breaks up the image into closely spaced dots. Uneven spacing and variations in dot size give the final image the illusion of dimension and value.
An illustration created by dots of varied size, the illustration can appear to be shades or tints
The process of converting continuous tone photographs into dots. A screening process done on a camera at the film stage of the pre printing process. (see LPI)

in printing, the technique of simulating shades of gray or color by varying the size of dots in a grid, or the number of pixels in a given area.
An image composed of many dots or lines
A continuous tone image, such as a photograph, that has been converted into a black and white image. Halftones are created through a process called dithering, in which the density and pattern of black and white dots are varied to simulate different shades of gray. In conventional printing, halftones are created by photographing an image through a screen. Halftones are used since the printing process cannot print the fine gradations of ink required for continuous tone.
gray scale image represented by bi level information.
The process (also called screening) by which a printer simulates continuous shades of colors while only using four colors: cyan, magenta, yellow, and black ( CMYK). When printed, individual pixels in an image will be represented by a random pattern of these smaller, various-sized printer dots.
converting a continuous tone image into a series of dots for printing.
The reproduction of continuous tone artwork, such as a photograph, by using dots to simulate the tones between light and dark. A halftone is made by scanning an image through a line screen to convert the picture into dots.
A reproduction of continuous-tone art (a photograph) converted into dots of various sizes so that it can be reprinted.
(pre-press): An image taken from your photo that has a dot pattern laid on it (or made up of dots) for better reproduction. Without the correct dot pattern, the photo would look like a bad copy machine copy (motley). Many of today's newer copiers automatically lay a pattern, thus better copies.
Representation of a continuous-tone photograph with a regularly spaced grid of dots of various sizes.
An image composed of dots that vary in size but are constant in spacing, giving the appearance of different colors or shades of gray.
A series of large and small dots that represent image areas of a continuous tone image. Continuous tone artwork can be converted into printable halftone dots using a process camera or by scanning into a computer and outputting onto film or paper as a series of dots. Even the photos in magazines are printed as a series of halftone dots. They are just smaller than we use in garment printing.
Refers to a method of representing the colors of an image with dots of varying sizes. If the dots are small enough, the colors of the image appear continuous. Halftones are created to prepare photographic images for reproduction across various print media.
() A reproduction of a continuous tone image.
Any image--such as a photograph--that exists as a series of small dots of varying size and color density, which serve to simulate the appearance of continuous gradations of tone. Halftones are necessary in the reproduction of photographic images; most printing presses cannot print continuous tones, so photographic images must first be converted to a series of dots in order to be effectively printed.
To reproduce continuous-tone images (photographs, etc.) by photographing through a fine screen to convert the image into a series of dots.
The result of photographically or electronically converting a continuous tone image--like a photo or shaded drawing--into a series of dots which offset presses and most digital printers can reproduce on paper. The various sizes of dots trick the eye into seeing shades of grey.
Illustrations or photographs produced in a dot pattern for reproduction by printing.
A photograph or image having dots instead of continuous tone making it printable in a variety of tones
Since the gradations in the colors of a photograph cannot be reproduced directly by a printing press, the printer re-photographs your photograph through a fine screen, which produces a series of dots on his printing plates. This representation of your photograph as a series of dots is a halftone. Large, densely spaced dots represent darker areas of the photograph, while small widely spaced dots represent lighter areas.
The use of dots to create a lighter-shaded version of a base color.
a series of dots obtained by photographing a continuous tone illustration or photograph through a finely ruled screen, that look like gray tones when printed
Halftone An image which is formed by using dots of various sizes and shapes. In printing, continuous-tone art (such as a photograph) is reproduced using halftones, which are either created by photographing the original artwork through a screen or by manipulating the image on a computer.
The way that tints or grays are printed is by breaking the solid color down into a pattern of dots so small that they cannot be seen by the unaided eye. When this technique is used to created a uniform area of lighter color, it is called a "screen tint." When it is used to reproduce a photograph it is called a "halftone."
A print that is photographically reproduced using a series of large dots to represent the varying shades of tones of a design. (In screenprinting, details and dark and light tones are represented by dots of varying sizes: small dots from light tones, large dots form darker tones.)
A printing process where colour intensity is controlled by the size of dots regularly spaced over the page.
A technique most often used in newspaper pictures -- a series of fine (black) dots, that when viewed from a distance, give the appearance of varying shades of grey. This process is relatively cheap-- you only have to run one color through your offset press.
Ink-printable image produced photomechanically or electronically to convert a continuous-tone image (for example, photograph, drawing, print, etc.) into a regular grid pattern of various-sized dots with equidistant centers to simulate shades of gray. This reproduction method contrasts with line art (no shading of tones), mezzotints (irregular shapes in random placement), and stochastic screening (same-size microdots) in a controlled random placement within a given area.
A picture in which the gradations of light are obtained by the relative darkness and density of tiny dots produced by photographing the subject through a fine screen.
The reproduction of a photograph formed by dots of varying sizes.
1. Using small dots or thin lines to produce the impression of a continuous-tone image. The effect is achieved by varying the dot size (or line width) and the number of dots (or lines) per square inch or centimeter (e.g., newspaper photographs). 2. The method and plate material used to create the image. The greater the number of dots or lines per inch the higher the resulting image resolution.
A piece of artwork (film or paper, positive or negative) in which continuous tones are simulated by regularly spaced array of small dots of varying size (smaller dots represent lighter areas and larger dots darker areas). Printing a black-and-white photograph on a printing press requires the creation of a single halftone; four-color process printing requires a separate halftone for each of the process colors.
In printing, a reproduction of an image of varying tone values, attained by printing dots of various sizes.
Picture with gradations of tone formed by dots of varying sizes.
A printed reproduction of a black-and-white photograph.

The reproduction of artwork such as a photograph, through a contact screen which converts the image into dots of various sizes and density. The density is measured by the dpi
The reproduction of a continuous tone original, such as a photograph, in which detail and tone value are represented by a series of evenly spaced dots of varying size and shape.
The method by which photographs and other images are printed by using cells of dots to simulate the tones between light and dark. A printing press is not able to change the tone of ink, therefore dots of color are used to trick the eye into seeing a continuous tone image. To accomplish this, the photo is shot through a mesh of a screen that breaks the image into tiny dots. The closer the lines of the screen, the smaller the dots and the more dots per inch, leading to a crisper image.
an image type that simulates gray scales by using various-sized dots, as commonly used in black-and-white newspaper photos.
it is an image that is comprised of dots.
A type of single-bit image composed of a pattern of black dots that fool the eye into seeing shades of gray. Examples of halftone images are the pictures you see in a newspaper. These images usually look very coarse.
A continuous tone image converted to dots for printing.
The darkness or intensity of a color between light and dark. In printing, the process in which graduation of tone, or shading, is obtained by printing a pattern of minute dots.
A halftone is the printed reproduction of your photograph or illustration. The more modern term to use would be "scan." The scanner will create a copy of your image for use in your book. The scanned image will be described in DPI (Dots Per Inch), and the minimum setting you should use is 300 DPI.
A process of converting levels of gray in a scanned image into dots of different sizes that simulate the shades of gray.
used in the printing industry. An image that has been converted from a continuous-tone image to a series of dots of various sizes that simulates the appearance of shading in a printed image. A photograph must be converted to a halftone before it can be printed on conventional printing presses. Since USM requires continuous-tone images on all ad creations, halftone images are not useable.
A printed picture that uses dots to simulate the tomes between light and dark. The halftone mimics the continuous tone of a black-and-white photograph by converting the picture to dots. Darker areas of the photograph have bigger dots and lighter areas of the photograph have smaller dots. The result is strikingly similar to the continuous tone of a photograph. see also four-colour process
To change a photograph or image into halftone dots so that the camera can reproduce. Can be used to create color variations or effects.
A plate, printed piece, or process involving the shooting of artwork through a lined screen which breaks up the art into a dot pattern.
The reproduction of a continuous-tone image, made by using a screen to break the image into various size dots. (see screen angle and screen frequency)
Black-and-white photographs are typically printed as dot patterns, enabling proper contrast and detail (compare with a xerographic copy of a photo). The dot patterns are produced by photographing the photograph through two dot-pattern screens. The greater the number of dots available in the screen, the higher the resolution of the final product will be. University standards usually mandate the use of at least 150 lines per inch (lpi) screens for halftones in publications that will be used off campus. Costs of producing halftones vary from printer to printer; the University Print Shop charges $5.00 per halftone while commercial printers often charge as much as $30.00 per halftone.
A photographic print is referred to as being "continuous tone" as the shades of grey are areas of flat or continuous tone. Printing presses can only print one colour ink at any given time so the photo has to be converted into a different format. The halftone format converts the discreet shades of grey into an array of round dots. Dark areas have few dots, light areas have many dots. In full colour printing these halftone dots are further separated into which colours belong on the cyan, magenta, yellow and black plates.
Converting a continuous tone to dots for printing.

an illustration reproduced by breaking down the original tone into a pattern of dots of varying size. Light areas have small dots and darker areas or shadows have larger dots.
A photomechanical reproduction process of a photograph made on a printing press. An original photographic image is re-photographed through a screen that transforms the continuous tones of the image into a series of dots, relative to the amount of darkness in the original. The new image is then transferred onto a printing plate. The amount of ink deposited onto the plate is determined by the density of the dot pattern. This process was sometimes used in Alfred Stieglitz's Camera Work.
The reproduction of a continuous tone artwork (such as a photograph) done by filtering light through a screen that converts the image into a pattern of dots of varying size.
In traditional publishing, a continuous tone image photographed through a screen in order to create small dots of varying sizes that can be reproduced on a printing press. Digital halftones are produced by sampling a continuous tone image and assigning different numbers of dots, which simulate different sized dots, for the same effect.
a photograph printed by any of the printing processes that, while they cannot actually print intermediate tones, can adequately represent them by using dots of various sizes generated by a scanner or halftone screen. A mid-gray is thus depicted using a dot that is 50% of solid.

The reproduction of continuous tone images, through a screening process, which converts the image into dots of various sizes and equal spacing between centres, or dots of equal size with variable spacing between them. For photos to reproduce well on a halftone device like a photocopier or printing press they need to be converted to a halftone.
the use of screening devices to convert a continuous tone image (such as a photo), into a reproducible dot pattern, which can be more easily printed.
output: An image that is composed of solid black dots of various sizes at equal spacing, which creates an illusion of various shades of gray. This is how continuous-tone images, such as photographs, have traditionally been reproduced by printing presses, which are not capable of generating true grays.
An image type that simulates greyscale by varying the sizes of the dots. Highly coloured areas consist of large colour dots, while lighter areas consist of smaller dots.
To photograph a continuous tone-image through a screen to convert the image into dots. The result is also called a halftone.
A color or black-and-white continuous tone image reproduced by changing the image into dots through the use of halftone screens. Because printing presses are not able to print true continuous tone images, a halftone allows tone gradation, in which the dots are perceived as a whole, depending on the halftone screen used, quality of the original image, and so forth. In computers, electronic algorithms can create digital halftone representations.

The process by which photographs are made into printable images. The first halftone photograph in a newspaper appeared in The New York Daily Graphic in December 1873. This first process proved impractical and was not perfected until the early years of this century, when photographs finally appeared on a regular basis in newspapers and magazines.
Different-sized black dots produced by turning particular dots on and off during printing, either on a laser printer, an image setter, or a printing press. The dots repeat in a regular pattern, creating the illusion of continuous tone. Color inkjets use their process colors in a similar scheme. Other colors are produced by laying down patterns of the process color dots, varying the pattern and ratio of each color. Halftone dots are not the same as printer dots.
An image seeking to imitate a continuous-tone image with the use of black and white dots, which to the naked eye seem to form continuous grey tones. Halftone screens are used in e.g. offset printing. The photogravure method reproduces real continuous tones.

The process of reproducing a continuous tone image as a series of various sized dots within a fixed grid that can be reproduced with ink. The finer the dot grid the higher the quality of the reproduction.
A special way of photographing a picture so that it appears to be composed of tiny dots.
Halftoning is the transformation of a grayscale or color image to a pattern of small spots with a limited number of colors (e.g. just black spots on white background), in order to make it printable. Printing is in its bare essence a binary process for each point on the paper: put ink (or toner) on paper (e.g. black) or leave the paper uncovered (e.g. white). This would suggest that only binary images (e.g. black on white or red on yellow) are printable.
