In screen prints, the mesh that is stretched over a frame for printing; in halftones, the dot pattern used to translate tonalities.
The light shading of a spot colour, eg. 50% screen of black is grey
1. Halftone screen (dot representation of a continuous tone image). 2. Silkscreen (a stencil printing process). 3. Computer display.
In graphic art it is a uniform dotted fill pattern described in percentage (eg. 50 percent screen).
The arrangement of dots of the same size in regular rows on film. A screen can be used to add a black or color tint to the printed page. Screens come in different percentages and different number of lines per inch (for the web presses, most commonly 85, 100, or 120 lines per inch, depending on the stock being run).
In traditional publishing, the screen was the patterned glass or film through which a photograph was converted to a halftone. In electronic publishing, the term screen is often used to refer to the halftone pattern itself.
The conversion of a continuous tone image to dots.
a halftone dot pattern on film of graded density, used to convert a photographic image to dots for printing called halftones; also, a lighter percentage of a solid color used to create various shades of that one color; sometimes called a “tint” or “tint screen.
The grid of lines on the contact screen or glass plate through which continuous-tone copy is photographed, breaking it into halftone dots for newspaper reproduction. Screens are designated by number of lines per inch. A tone defined as a percentage of a solid color; used as a background to accent an area of an ad.
In prepress, a grid pattern of lines of dots aligned at 90 degree angles that is used to break down continuous tone art into a seriew of dots to create halftones. Also, the corresponding pattern created I the printed image.
Usually a reference to a printed screen resolution. (See also "halftone" and "LPI")
A printing technique for printing shades of colour, e.g. a screen is applied to make pink from red
Used to stimulate various shades of color through use of dots, lines or textured patterns.
to reproduce a shaded area in a printed piece. Also, a photographic tool for making halftone images from a continuos tone photo or illustration.
To convert a continuous-tone image into a halftone or a solid into a screen tint.
A grid used in the half-tone process to break up an image into dots. See Halftone. A mechanical screen is a piece of transparent plastic bearing type or other material that is placed as an overlay on base art to simulate halftone work.
A pattern of tiny dots used to create gray areas; to screen a photo is to turn it into a halftone.
a synonym for half-tone screen.
A pattern of dots used to reproduce color or grayscale continuous-tone images. The fineness of the screen can vary from 65 to 200 or more lines per inch. Typically, newspapers are print-ed with a 65 to 85 line screen and magazines are printed using a 133 or 150 line screen. The higher the line screen, the finer the dot and the crisper the image is.
project onto a screen for viewing; "screen a film"
a grid pattern of dots applied to an image to create a percentage of full ink coverage

To produce a HALFTONE of a continuous-tone image.
How a continuous tone image is broken up into a halftone image.
A network of metal or fabric strands, mounted snugly on a frame, and upon which the film circuit patterns and configurations are superimposed by photographic means.
A pattern of dots used to create the illusion of a continuous tone photograph. Measured in lines per inch (lpi).
Used in the halftone process to reduce continuous tones to a series of solid dots (See Halftone). Also refers to shading a block of text - many times in boxes or set apart.
1) A display device capable of showing an image 2) Grid of dots or lines placed between a camera and artwork which has the effect of dividing the picture up into small dots, creating an image which can be used for printing
A cloth material (usually polyester or stainless steel for circuit boards) coated with a pattern which determines the flow and location of coatings forced through its openings.
A halftone screen applied in the imagesetter and usually having a monotone value of dots. It is used in direct contact with the plate to obtain a lighter shade of a solid colour. We use a 20% as standard default with 10%, 40%, and 60% optional.
An easy way to add varying shades of ink to a printed page. The amount of ink printed on the page is varied by printing it as a series of small, equal-sized dots, usually too small to be seen without a magnifying glass. Screens can be used to emphasize or subdue various elements. Type may be printed over a screen. Best results are obtained if the screen is 50% or less. Type may be reversed out of screens that are 50% or darker.
Glass or film with cross-ruled opaque lines used to reproduce continuous tone artwork. Expressed in number of lines to the inch.
a dot pattern used in the reproduction of photographs or shading.
Printers / Scanners. To break up continuous-tone copy into dots for reproduction as a halftone. Line screens are designated by the number of ruled lines they contain: from 50 lines per inch to 500 lines per inch. The greater the number of lines per inch, the sharper and fine the printed half-tone. The selection of the screen is dictated by the paper, press, the nature of the copy
A sheet of film having lines or other patterns.
Traditionally, the device (a piece of glass or film with tiny transparent areas) through which a photograph is converted into a halftone; loosely, the halftone pattern itself. The eye sees a pattern of dots looks as a shade of gray. The smaller the dots, the lighter the shade; the larger the dots, the darker the shade perceived. Dots are produced by photographing the artwork (photograph or any contone illustration) through a screen of fine lines, which can vary from 65 to 150 or more per inch. 65 or 85 line screens are used for printing newsprint. Better paper can accommodate more detailed printing produced by finer screens, which yield higher resolution. A screen has three attributes: 1. The angle at which rows of dots are placed relative to the horizontal plane; 2. The screen ruling (also known as resolution but NOT resolution of the output device) in lines per inch, specifying pitch of the screen (space between rows of dots); 3. Dot shape (shapes of dot most commonly used are round, elliptical, and line).
A sheet of film having lines or other pattern.
A grid pattern or dot structure on film or glass used to produce shaded areas in photographs or line art.
(see dot screen)
The lined glass, now called contact film, through which images are photographed to create halftones. Shooting through the mesh of a screen breaks an image into tiny dots. The closer the lines of the screen, the smaller the dots and the more dots per inch; the farther apart the lines of the screen, the bigger the dots and the fewer the dots per inch. The higher the dots per inch, the smaller the dots are, therefore creating a finer, crisper image. The coarseness or fineness of the screen is measured in the number of horizontal and vertical lines per inch. The less a paper absorbs and spreads ink, the finer the screen that can be used. Newspapers use coarse screens with 55 to 85 lines per inch. Most trade publications use 85 to 110 lines. With traditional printing, a coated paper can hold the small dots from a 200-line screen. With waterless printing, the paper can hold the dots from an even finer screen, 400 lines and greater. Though this approaches the quality of continuous tone, it is hard for the eye see to discern the differences in resolution above 200 lines per inch.
A pattern of dots used to reproduce color or grayscale continuous-tone images. Screens are produced by photographing the original artwork through an actual screen of fine lines. The fineness of the screen can vary from 65 lines to 150 or more lines per inch. Sixty-five- to eighty-five-line screens are used for printing on newsprint. Better paper can accommodate finer line screens. See also AM screening, FM screening, and halftone.
The ruling used to determine the dots per unit area in developing tonal values in the printed piece. Screens from which letterpress halftones of photographs are made range from 60 lines-per-inch for printing on newsprint to 150 lines for printing on coated paper. Offset halftones for printing on most surfaces range from 133 lines to 200 lines.
a set screen pattern, such as the TECHNET, SETPASS, or SETMAS screens
Screens of varying percentages (size and density of dots) are often used to highlight text areas through overprinting. Screens are readily available in ten percent increments, can be ordered on several days' lead time in five percent increments, and can be specially manufactured on several weeks' notice in one percent increments. Experience thus far indicates that screens applied to text via desktop publishing applications tend to reproduce poorly. It is therefore recommended that areas to be screened be clearly marked for mechanical application of screens in the manual stripping process. See also Halftone.
Oil trading jargon for the electronic network quotes of futures market prices. Other nicknames include "the TV" and "the print." The industry discusses physical market activity and does business at levels which sound like "screen plus 25" and "85 points under the print."
Series of dots used to reproduce halftones or blended colors. As the percentage of screen increases, the color prints darken.
Series of dots used to reproduce halftones or blended colors. As the percentage of screen increases, the color is printed darker.
A uniform dotted fill pattern, described in a percentage, such as 50% screen.
In offset lithography, a screen is a glass or film with cross-ruled opaque lines or vignetted dots used to reproduce continuous tone artwork such as photographs. To create a halftone, an image is shot through the mesh screen to break it into tiny dots. The closer the line screen, the smaller the dots and the more dots per inch and, hence, the finer and crisper the printed image. Less absorbent papers reduce the spread of ink dots and, therefore, a finer line screen can be used.
Sheet of transparent film or glass carrying a regularly repeated pattern which may be used in conjunction with an area negative to photo-mechanically reproduce areas of the pattern.
A regular pattern of tiny dots that can be used to print a full range of tones.
An area printed as a pattern of dots rather than a solid area of ink, or the process of creating this dot pattern.
A network of criss-cross lines which break up a continuous tone image in to patterns of dots which can be printed either black or white to represent gradations of gray. See also: Crossline Screen, Contact Screen and Halftone Screen. to top
the process of breaking down a photographic image into dots for printing; originally named from a patterned glass screen inserted between the illustration and the light source on a camera, and now used to describe the process and also the size of the dots created (hence the quality of the reproduction).
in graphic arts, a uniform dotted fill pattern, described in percentage (for example, 50 percent screen).
contact screen A halftone screen on film having a dot structure of graded density, used in vacuum contact with the photographic film to produce halftones.
A fine pattern of printed dots used to achieve varying tints of a color or to create a halftone image.
In image reproduction terminology, an area made up of small geometric forms of either regular or random arrangement, for example round, square or other shaped dots and lines. The screen is used to convert contone images into a black/white or full-color representation suitable for printing. This is done by varying either the size or the frequency of the elements to reflect the brightness of the image.
Lightening the ink in an area through a dot pattern for design effect or emphasis.
In reference to printing, creating a tone effect in the printed image; also called a benday. Screens from which letterpress halftones of photographs are made range from 60 lines-per-inch for printing on newsprint to 150 lines for printing on coated paper.
a cross-ruled glass plate (or a piece of film or plastic) that is placed in front of the lens of a camera (or in contact with film) in order to break up copy into dots that will carry the ink in reproduction. Screens are designated by the number of ruled lines per inch they contain (from 50 to 500) or by the ratio of dots to clear spaces. The greater the number of lines per inch, the finer the reproduction will be.
The pattern which enables the reproduction of tones on a printing plate. The dots of an offset screen become lighter towards the edges, whereas in gravure a hard-dot screen is used to create the resist. Different screens used in graphic art include the grain, irregular, sand, aquatint and mezzotint screens.
(1) Use of an outside list (based on credit, income, deliverability, ZIP code selection) to suppress records on a list to be mailed; (2) halftone process in platemaking that reduces the density of color in an illustration.
A halftone screen on film used in conjunction with photographic film or paper to produce a halftone image from continuous tone art.
Short for halftone screen. The reproduction of continuous-tone artwork, such as a photograph, by screening the image into dots of various sizes. When printed, the dots merge to give the illusion of continuous tone.
Printing term for photograph.
The dot pattern used on offset lithography plates.
Piece of film with dots of uniform density, used to make plates that will print screen tints. See also halftone screen.
To transform a continuous tone image such as a photograph into a series of dots for printing purposes.
