I just encountered information from the author of a recent publication
for a work on a new color difference formula (∆E_NS) for viewing samples
with no separation between them - a viewing mode common in many printing
applications (packaging, tiling, spot color matching, ...) for which
existing formulae underpredict perceived differences.
Do you think it is useful and practical addition to the color
measurement practice?
Here is a link to the two publications:
