I realize you were adding info, not necessarily advocating for the ColorTron, but heres a response to your response: In a message dated 1/24/00 7:00:34 PM, hsimpkns@admin2.memphis.edu wrote: >To add to this regarding the ColorTron II.

Actually, all that is necessary is to place the ColorTron on the screen vertically, not horizontally; any structural engineer would see that immediately, it must have been non-structural engineers that designed it the other way <G>. > >As a swatch reader: Accuracy: I bought a Q-60 reflective target with a >custom data file, that is, the data file was generated from the individual >target using a high accuracy spectrophotometer and I'm getting ColorTron >values within 3 deltaE of the data file values (2.6 or less) although I >have >not had the time or energy to read the entire target. I can generally get reading less than 3 delta-e with my ColorTron as well, but the devices are not consistant, some are far worse than this... and 3 delta-e is not really close enough for good profiling... > Time: For profiling it >takes 2-2.5 hours to read each of the 270 patches of an RGB profile target >once. And with a DTP-41 it takes under 15 minutes to accurately read a thousand. Unless your time is free, or you are a hobbiest, it makes sense to get the strip reader in the long run. 270 patches is rather a compromise on quality, 3 delta-e is rather a compromise on accuracy, and two and a half hours of carpel tunnel inducing work is rather a lot of time... but yes, it can be done; I did it many times myself.
