About 10 years ago a paper was presented by John Dalton of Apple
Computer detailing a method for ordered stochastic screening that
eliminates almost all the problems both Mr. Gill and Mr. Krawitz are
describing. I believe it was presented at either an IS&T, SPIE, or
printing conference. For some unknown reason it has gone unnoticed.
In brief, the algorithm is a method for creating ordered stochastic
screens that show no edge tiling artifacts (the pattern is
manipulated in Fourier space to produce an equal intensity frequency
spectrum) and their use would also solve most of the problems causing
color contamination of neutrals using current stochastic algorithms
(such as debated here about Epson printers).
Sorry, I don't see the relevance. We were talking about color plane
co-dependent screens (that is, making the
screens for different color planes sensitive to each other patterns),
and the feature of the method you mention
(from your summary) is elimination of edge tiling artifacts. There
doesn't seem to be a connection. As
to neutral color contamination, I don't quite follow what this has to do
with the screen. This is surely the
arena of the color correction system ?
