Dot gain or spread is the increase in the size of a printed dot from its original size. This can occur during the printing process when the dot is being transferred from the printing plate to the paper. Dot gain can also happen when the paper absorbs more ink than expected.
Dot gain can affect the printed image in a number of ways. For example, if the dots get larger, they will appear darker and will reduce the overall contrast of the image. This can make the image look muddy. In addition, if the dots spread too much, they can start to bleed into each other, resulting in a loss of detail and an overall deterioration of the printed image.
Dot gain is a problem that printers have to deal with on a daily basis. There are a number of ways to combat it, such as using special paper coatings that help to limit the amount of ink that is absorbed, and adjusting the printing process to account for the increased dot size.
Despite the challenges, dot gain is an essential part of printing and must be taken into account to produce the best possible print quality.
Dot gain or spread is the increase in the size of a printed dot from the original size. This can be due to many factors, such as the ink, the paper, the printing process, or even the environmental conditions. It is important to control dot gain, because it can have a big impact on the final print quality. If the dots get too big, they can start to bleed into each other, making the print look fuzzy. Conversely, if the dots are too small, the print can look dotty and pixelated. There are many ways to measure and control dot gain, and it is an important consideration in any printing process.
