DIGITAL PROOFING -- Taking Measure of a Proof

Pick Your Target

Digital technology has expanded the range of targets that can be used effectively, the consultant notes. That flexibility comes from combining device calibration and color management with the capability to mix colorants enabled by toner and ink-jet systems.

As for how the rules have changed, Zwang reports the study found that color has become less of an issue. "Most of the color proofing vendors have adopted an ICC-based, color-managed workflow within their systems. As a consequence, if you look at the delta errors in IPA's test results, all of the systems did well matching to the targets, especially the known target. They averaged 2.0 to 2.5 delta E variance," he says.
