Complex computer-to-plate devices–often known as digital platesetters–require sophisticated tools to ensure that production is consistent and within desired parameters. These devices receive digital information from myriad sources using different data formats and variable RIP and output standards. Moreover, these devices must image a wide variety of printing plate types, which are developed using distinctly different processes.The incredible number of variables in the computer-to-plate process make it difficult for an equipment operatorto control the process without objective, interactive measurement tools.The Ugra/FOGRA Digital Plate Control Wedge is a further development of the widely used Ugra/FOGRA Postscript Wedge–regarded at the standard tool for controlling PostScript output devices.

The Ugra Plate Control Wedge assists operators in controlling the lithographic and flexographic platemaking process. In addition, the device is useful in evaluating the proofing process and in printing tests. The following can be evaluated on the printing plate, using the Ugra Plate Wedge:

  • Exposure
  • Exposure Latitude
  • Optimum Resolution
  • Gradation
  • Rendering of Halftone Dots
  • Fingerprinting of Plate, Proof and Press Curves
