Beyond this, Cassino says, inkjet has an inherent ability to make a proof match the press more closely than any other device because of its ability to move through three-dimensional color space changes. "Pressmen want and trust an ICC-profiled proof," Cassino says.
As to substrate, he adds, ICC profiling also takes care of trap, dot gain, saturation, and "paper white" considerations, based on the inkjet proofer's color-managed ability to simulate background color on stock that is brighter and whiter than the stock that will be used for the job. Cassino does acknowledge that, in packaging, with the absence of a "true" halftone dot, "you do worry about moiré." However, he explains, stochastic screening and dithering can ameliorate these concerns.
