The «Visual PRINT Reference» (VPR) is intended to check every production process step in an efficient way. The test form consists of a total of eight pages, which are provided as RGB and CMYK data sets via download link and as printed reference sheets.
The Visual PRINT Reference contains specially selected images, which quickly show printing process variations that reveal printing problems. Using the test pages you can visually assess the monitor colour appearance, digital proofing and the printing acc. to ISO 12647-2:2013. For measurement-based evaluation the «Ugra/Fogra Media Wedge CMYK v3.0» and the «ECI GrayCon M i1 v3» are integrated on all 8 test pages.
