A control patch on the Ugra/FOGRA digital plate wedge, required for the determination of the printing characteristics of a printing press.

It consists of (nine) patches increasing in most cases in increments of 10 percent from an area coverage of 0 to 100 percent (solid patch) for the densitometric control of tone values and dot gain during printing.
