Added information to relate each test with the required digital file to print. For example, “Colorimetric Evaluation (uses Digital Press Form 1)”. Version 0.5 We the following for their comments that have been included in this revision Jeff Collins, Lode – Deprez, Joe Fazzi, Bill Garno, Patrick Harrington, Fred Hsu, Lior Lewinz, Mike Rodriguez, Mike Ruff, Larry Warter. Special thanks to Mark Lewiecki, Adobe Systems, for his elegant solution to creating an automated numbering system in the slugline. Section 1.7 - Target characterization data set. Instead of a specific reference printing condition, supplier is now able to specify any established printing condition of their choosing. Section 1.8 - Measurement Configuration - now includes description and use of X-Rite XRGA technology to reduce effect of inter-model agreement. Section 2.2 - Added explanation for ∆H*. Section 2.2 Clarified the procedure for calculating i.e. using 5 CMY patches compared to their – ∆F, characterization data set L*a*b* values. Section 2.2 Removed tolerance for paper white. – ∆E Section 2.3 50% C, M, Y patches are not part of the IDEAlliance Digital Control Strip, but are – available via another area on the press sheet. Section 2.4 New section to describe procedure to provide automated numbering on each page, #1, – 2, 3,…1000 as automated slugline, best rendered with PDF Print Engine 2. Section 2.5 Uniformity within a press sheet, in this section changed standard deviation to maximum – deviation in keeping with trend in ISO standards. Section 2.10 Measurement of gloss this test had no stipulated tolerance. Now we specify that the – – print process should not change the gloss of the printed to unprinted stock by more than -10/+20 gloss units. Annex D example certificate and reporting is provided. – De-inking tests for INGEDE method of de-inking were considered but are not included as part of the – certification procedure due to time and cost considerations. Changed name throughout document from Digital Print Certification to Digital Press Certification.
