Flexographic Dot Delivery Rules

In flexo printing, because the elasticity of the photosensitive resin plate used is relatively large, and a certain printing pressure needs to be applied during the printing process, even though light pressure printing is used in the flexographic printing, it still leads to image dot on the printed matter. The extended image expands and causes changes in color and gradation replication. In practice, by measuring and plotting the corresponding flexographic characteristics, it can be seen that the dot expansion in the flexographic printing process is very serious, and the dots below 10% are difficult to control. Therefore, special treatment should be performed for the high gloss region. Should try to flatten the net.

Compensation for dot gain can be done at the scanner side or on the imagesetter, preferably on an imagesetter. The edges of the small dots generated after exposure are relatively neat and of good quality.
