There are different dot shapes for screening: round, square, euclidean, elliptical, ... which one is the best for flexography? (*) When choosing the dot shape for plate screening, it is important to consider the characteristics of the different geometries and their influence on the printed result. When the plate is inked by the anilox roll and [...]
How many resolutions do we need to know in flexography? There are four important information related to resolution within the flexo workflow. 1# The resolution of the anilox roll, or its line-screen or cell-count, that is the number of cells engraved on the surface by linear unit of measure. We express it, in the metric [...]
Have you ever wondered why we need to use different screen angles in flexography? First of all we need to remember that we consider the screen angles when we look at the final printed product, so the parameters we set in the prepress/imaging workflow are meant to obtain the angles as described. Then we need [...]
Dot dipping describes the condition whereby the smallest dots on a flexo plate dip into the cells of the anilox roll when forced by the impression between anilox and plate. Some dots of the plate, dipping in the cells, will carry more ink than what was expected, resulting in dirty printing in highlights, typically [...]
The term “round dot” refers to the screening algorithm that tends to draw round shaped dots. Let’s not forget, however, that the original digital file is made of square pixels. These pixels are the binary information that is sent to the laser to write the image: write / don’t write = on / off. Therefore, [...]
