How to test your proofer?

The most critical is to print, measure, and analyze IT8.7/5 (TC-1617) with Color Management ON. The key parameter is E-Factor. 

In most cases, we are not observing variation issues - printers used as proofers are high-quality low-speed devices, which is why we are starting from the Accuracy test skipping Variation. If the Accuracy is not good we can check Variations with the VI-816 Test form. This is the only printing device where the Variation test is optional.

• Print IT8.7/5 (TC-1617) - be sure to simulate desired Print Conditions represented by the selected ICC Profile (GRACoL, ISO Coated  v.2, or any other)
• Measure IT8.7/5 (TC-1617) chart with CC Capture or 3rd party software and upload data to track in Print Inspector. Be sure that track settings are corresponding to your RIP simulation profile and that SCCI is turned OFF. It is important to measure a printout that is perfectly dry (ISO Standards requirements, also ICC Profiles are made for dry prints)
• Analyze Report - focus on E-Factor —  All Patches 95th ∆E2000, check also Substrate, Primaries, Secondaries, G7, and TVI curves. See samples at the bottom

What can be a realistic goal?

We can expect the most from a proofer among all printing devices. We know from the conducted research that it is possible to keep the proofer permanently with the E-Factor value around 1.0 This should be a goal for all demanding users. A very good proofer should finally print with E-Factor in the range of 1.1 to 1.5
