Increase in the size of the dot in a halftone or screen due to physical or optical causes. Physical dot gain occurs as the image is transferred from plate to blanket to paper. Optical dot gain occurs when light scatters around the halftone dots and within the paper beneath. In addition, dot gain may occur during generation of film and during the plating process.

When a printed screen dot prints larger than it's appearance on a negative or proof. The result is a darker printed image. Ink absorbsion, paperstock and calibration are factors that contribute to dot gain.

During the printing process, as the wet ink spreads, dots in halftones increase in size. Dot gain is affected by paper type and press type.

When the dots in halftone printing become larger than desired.

The increase in the size of a halftone dot caused by the spread of ink during printing - can result in darkening or loss of detail

A printing defect in which halftone dots print larger than they should, causing inaccurate color reproduction.

an increase in size of a printed dot on the paper making the image appear darker.

a physical and/or optical measurement and theoretical calculation of the apparent increase in dot area from one medium to another. Normally expressed as the difference between a midtone (nominal 50%) dot area on a film negative and the printed dot area; for example a 50% film dot area which prints as a 78% dot has a 28% dot gain. Dot gain (and loss) are normal and must be controlled throughout the prepress and printing process.

A gain (or loss) in the halftone dot caused by ink bleeding or spreading as it is absorbed by the paper. The result is darker or muddier printed images.

Darkening of an image when it is printed on a printing press, caused when the ink hits the paper and spreads out. Dot gain is greater on uncoated paper than it is on glossy paper, because the ink soaks in to uncoated paper. Scanned images can be lightened in the MIDTONES to compensate for dot gain; when the image darkens on press, it will match the original.

A problem that occurs when dots i a screened image print larger than necessary, thus darkening the image.

When an ink dot enlarges through absorbtion on a porous paper. This affects the overall tone of an image, as the size of the dot is equivalent to the tone it represents.

The spread of each ink dot as it is being applied to paper or plastic film and absorbed. Dot gain can be compensated for by experienced high-end pre-press operators.

A printing term which describes wet ink coming in contact with paper and spreading as it is transfers. As the halftone dots are applied to the paper, the wet ink spreads, causing the dots to increase in size and halftones to appear darker. Paper weight, type of paper (coated or uncoated), press type (especially web presses), affect the amount of dot gain in a given printed piece. Dot gain may be compensated for by calculating its effect before a print job and lessen the density of the images to be printed before you output film.

The result of uneven pressure in the printing press process, which causes some squashing of dots during transfer of the image to paper. The percentage of dot enlargement varies with dot size. In color process printing, the tonal scale can be distorted by dot gain to cause color to appear darker.

In halftone printing, the tendency of the ink used to create halftone dots to flow outward as it is absorbed by the paper. Too much dot gain can create a cloudy or dark image.

An imperfection of printing that causes halftone dots to print larger than they should. This imperfection is mainly caused by the absorption of ink by the paper and causes the reproduction to print darker than it should.

Darkening of halftone image during printing due to ink absorption in paper, causing halftone dots to enlarge.

The gain in size of the printed dot, as a result of ink, paper, printing pressure, pre-press operation, or any combination of these. The dots that are printed are larger than expected; this result can be seen in the darker tones and/ or different hues.

Dots printing larger on paper than they appear on the plate.

The undesirable spreading and enlarging of ink dots on paper, which causes colors or shades to look darker.

the growth in size of a halftone dot from the time it is made on the halftone negative to the printing on paper. It can be caused by such aspects as paper, ink formulation and overexposed films.

Increase in size of a dot from the film to the printed sheet. All printing processes have dot gain which consist of two parts, physical dot gain and optical dot gain due to the physics of light absorption and reflection. This causes darker tones or stronger colours.

A tendency in the printing process for dots to print larger than they appear on the printing plate.

The concept that inks are absorbed by papers at varying saturation levels relative to the coatings or lack thereof of the papers used. For example, inks on newsprint type paper (uncoated) have a greater absorption tendency than inks on gloss (coated) paper. The greater the dot gain (or absorption of each dot of ink), the darker and less crisp the printed images appear.

The apparent dot size increase from the film to the printed reproduction.

A printing defect where dots are printed larger than expected causing darker colours

A mechanical effect in printing, which causes dots to print larger than they should and creates darker tones or colours.

A halftone dot will become larger in the transition from film to print - this has to be planned for in the reproduction process.

The change in size of a printing dot from the film to the printed sheet, expressed as a percentage; an increase in dot size from 50% to 60% is called a 10% gain.

When dots print slightly larger on paper than they are on the negatives or plate, causing darker tones and colors in printing. Caused by paper absorption.

Enlargement of the halftone dot between film and print: which should be assessed and allowed for in reproduction.

An increase in the size of the halftone dots resulting from film and plate exposure, tack or viscosity of printing ink, ink film thickness, machine pressure settings and internal reflections of light.

A term that refers to the "weight gain" of halftone dots. During the printing process, the half-tone dots increase in size. Because this is an inherent part of the printing process, the effect of increased dot size should be anticipated ahead of time.

The spread of ink on paper, causing the dots which make up the image to print larger than they were on the film or plate. The images may become distorted, appearing darker with less clarity.

The tendency for the dots in halftones and four-color images to print larger than they are on the film or plate. There are 55 more items in the archives for this category Tips and Tricks Watch this space for updated production information.

An increase in the size of halftone dots that occurs when paper absorbs the ink beyond the intended boundaries. Dot-gain usually happens with lower-quality papers such as newsprint.

The tendency of ink dots to increase in size when they are printed. Porous paper soaks up ink and the halftone dot swells causing the image to become darker. Dot gain can be reduced by using coated paper.

A term used to describe when dots are printing larger than they should.

The tendency in printing for dots to print larger than they should. The increased dot size causes darker tones or colors, and an increase in the density of light reflected by the image. This is most pronounced when using poor quality papers, or when inks are absorbed and spread.

The enlargement of halftone dots on the press resulting in a loss of detail in the image.

The effect in which the wet ink dots are squeezed by the printing press blanket and spread slightly resulting in darker tones or stronger colors.

When a printer's ink hits paper, some spreading and absorption occurs. This causes the actual size of the ink dot to be larger than its theoretical size. The gain in size is measured as a percent and is referred to as the dot gain. Matte papers usually show more gain than glossary papers.

term to describe the occurrence whereby dots are printing larger than they should. ( see also, four-color process, halftone)

In printing, a defect in which dots print larger than they should, causing darker tones or stronger colors.

Dot gain is where the halftone dots of an image print larger than the size they were on the films or printing plates. This results in some loss of detail. Some degree of dot gain is an unnavoidable part of the printing process and there are settings in a number of desktop publishing tools to allow for this. Adobe Photoshop, in particular, has settings to allow for dot gain under it's color settings preferences.

The amount that an ink halftone dot expands when applied to the surface of a paper. This is usually a factor of the type of press and the absorbency of the paper.

An aberration when during the making of halftone film or plates, the dots become slightly enlarged.

A defect that occurs in the reproduction process in which dots print larger than they should, causing darker tones or colors. Compensating for press dot gain is a key element in calibrating a digital prepress system.

the tendency for the dots of halftones and four-color images to print larger than they are on the film or plate. This reduces sharpness and can change the color of a piece

A printing artifact in which dots print larger than desired, causing changes in colours or tones.

Phenomenon of halftone dots printing larger on paper than they are on films or plates, reducing detail and lowering contrast. Also called dot growth, dot spread and press gain.

The occurrence when dots are printing larger than they should

The phenomenon that occurs when ink is transferred from the plate to the blanket of the press and finally to the paper on which it is being printed. A dot for a halftone or a screen gets larger because of to the mechanical process of transferring ink. Dot gain can be and is controlled by strict quality measures. The scanning of halftones must be tightly controlled to compensate for dot gain on press to ensure that halftone quality does not suffer.

Term used in reproduction technology for the deviation in size of a previously calculated theoretical screen from the dot and screen actually printed, a phenomenon to be considered in order to ensure the quality of a printed product. This variation in dot size depends on several factors, including the printing method, substrate, printing ink, printing conditions and total ink limit.

Darkening of halftone image due to ink absorption in paper causing halftone dots to enlarge. Terms to describe the occurrence whereby dots are printing larger than they should.

A condition where the size of a halftone dot is increased during the printing process. Frequently caused by ink spreading due to low viscosity or by paper absorption. Other terms: dot spread; ink spread.

When ink spreads on paper, it may cause the dots which make up the image to print larger than they were on the film or plate. The image may become distorted, appearing darker with less clarity.

Effect produced when individual dots in a halftone screen or other patterns print larger than their intended size, resulting in darkening of a printed image. Sometimes referred to as "tone value increase" in recognition of devices, like inkjet printers, that don't use conventional halftone dots.

a printing defect in which dots print larger than intended, causing darker colors or tones; due to the spreading of ink on stock. The more absorbent the stock, the more dot gain. Can vary by type of ink as well.

In printing, a defect in which dots print larger than they should, causing darker tones and stronger colours.

the phenomenon of dots printing larger on paper than their actual size on negatives or plates.

Pisteenkasvu Punktförstöring Difference of the tonal value of the print and the corresponding tonal value of the film. An increase in the size of halftone dots that may occur as a result of errors or imperfections in any of the steps between screening an image and printing it onto paper. Common causes of mechanical dot gain are incorrect plate exposure, low viscosity of printing ink, high ink film thickness due high ink requirement of paper and too much pressure in ink transfer. Dot gain is a sum of physical and optical dot gain. See also Physical dot gain and optical dot gain.

The effect that is described when individual dots in a halftone screen or other such patterns print out larger than their intended size, resulting in a darkening of the image.

The tendency for the dots of halftones and four-color images to print larger than they are on the film or plate. If the printer or color house does not compensate for this, images may be distorted, appearing darker or less vivid than intended.

The tendency for the dots of halftones and four-color images to print larger than they are on the film or plate. Printers adjust for dot compensation based on the type of paper selected to make sure images don't look distorted.

An increase in the size of halftone dots that may occur as a result of errors or imperfections in any of the steps between screening an image and printing it onto paper. Common causes of mechanical dot gain are incorrect plate exposure, excessive tack or incorrect viscosity of printing ink, excessive ink film thickness, internal reflection of the ink, or too much pressure between the blanket roller and the impression cylinder.

The phenomenon that occurs when ink expands its coverage during printing onto a substrate; often caused by abnormal or excessive absorption by the substrate or low viscosity inks.

Printers / Scanners. A printing defect in which dots print larger than intended, causing darker colours or tones. Dot gain measures the increase in halftone dot values that occur during the offset printing production process. Total dot gain is measured as the difference in apparent dot size between the final printed product and the original film. Dot gain occurs as the result of both mechanical and optical influences on the original dot size

Dot gain is a phenomenon in printing and graphic arts whereby printed dots are perceived and actually printed bigger than intended. This causes a darkening of the screened images or textures, especially in the mid tones and shadows.
