One issue I haven't seen brought up in relation to scanner quality is the light source used. Since all mixed color printing processes are metemaric to some extent it would seem that the light source and the exact CCD filter responses could have a considerable effect on the accuracy of profiles. For example if the light source contained a large UV component then the fluorescent whiteners in many bright white papers would be activated to a greater extent than they would be under incandescent lights. Even profiling packages that generate scanner profiles from known targets would be affected since the exact dyes and spectral characteristics of the target would be different from the prints being profiled so that a print and a target that looked identical under D50 viewing conditions might appear quite different to the scanner. Do scanner manufacturers specify what viewing conditions the scanner emulates? -- Mark - Please turn off HTML mail features. Keep quoted material short.
