DigiCap is equivalent to AWS PlateCell Patterning and Esko's Groovy Screening features. However, DigiCap has the advantage, because the other two use angled geometric screens to texture solids and shadow areas. In any situation in which geometric screens are used, they can interfere with image halftone screens or the anilox roll to produce visible moiré. Even solid areas can show screening artifacts.
DigiCap avoids these problems because it uses a stochastic screening algorithm to achieve solid and tonal texturing. With stochastic imaging, there are no additional geometric patterns that can cause moiré.

Note: The disadvantage of both is that with reduced ink laydown during a press run, moiré can develop in areas textured with these periodic patterns. DigiCap is not subject to this moiré, because it is a stochastic texture.
When configured properly, DigiCap is an effective tool for achieving the best possible solid ink laydown, with maximum density. It is also effective for reducing gain in shadow areas and achieving better separation of tonal areas in shadow regions.
