This workbook  returns a handsome report of  all color metrics needed for the IDEAlliance G7 Digital Press Certification process, a badge offered  only at the Manufacturers level. Use this newly updated test to compare your digital press to industry standards for  Colormetric Accuracy using the latest G7 metrics and test charts. Also test for Run Uniformity, Repeatability and Macro Uniformity or M-Score. It also adds Topocolometric (heatmap) visualizations for  Delta E uniformity of the sheet.

This is the basic M Score workbook created for Idealliance. This is a 3-sheet method which requires an iSisXL scanning spectrophotometer. Based  on ISO TC-18621-21:2013. It returns an overall Uniformity or M-Score pass/fail per Idealliance specs for the G7 Digital Press Certification procedure.

It is available as a tool for those manufacturers interested in Idealliance's Digital Press Certification procedure.

This workbook calculates M Score using a completely new, single page chart. It's much faster than the traditional 3-Sheet method and can be  measured with an i1IO, iSisWide or FD9. Multiple measurements can now be taken into consideration easily.

Evaluating  sequential sheets for presses with multiple prints per belt or cylinder becomes highly efficient. Plus, checking larger sheet sizes such as 2up and 4up sheet becomes practical given the limited size of measurement devices.

The first step in any ECG workflow is to bring the press into G7 compliance for CMYK and to use SCTV curves for the additional colorants. Lots of ways to get G7 curves for CMYK, this is a tool to calculate SCTV for the OGV used in most ECG workflows.

This workbook is setup to ingest CGATS data of the IDEAlliance SCTVi6 ECG color ramps measured with an i1 or i1IO spectro and returns curve data for each colorant plus black. 

This uses a custom 7C Linearization chart to create CMYKOGV curves based on the SCTV ISO 28645 Standard math. Allows you to use one curve tool for both CMYK and OGV. 

Universal chart can be used in either the iSis or i1IOPro2/3 Spectrophotometers.

This workbook provides feedback on how colors shift under different lighting conditions. Measure the control strip 3 times using a Baseline (D50) and two other lighting conditions (examples are D65, F11) and the workbook calculates the Metamerism Index for each patch using the DIN 6172 formulas. Helpful for answering the question of which  inks/substrates exhibit the most or least metamerism and which colors are affected most and least. Red indicates a high index from the baseline, green the low
