Good afternoon
I have just started using Argyll CMS to produce profiles for my Epson Pro
3880 printer, using a Datacolor SpyderPrint colorimeter. I have
successfully produced several profiles, but I don't understand the Peak,
Average and RMS errors that colprof displays when it completes the profile
generation. First, could you give me an idea of 'typical' values for these
errors? Second, because the SpyderPrint is only able to take a single
measurement at a time (using the 'Measure' window in the Datacolor
software), it is very easy to get the patch numbers and readings mixed up.
I'm sure this has happened, as I sometimes get peak errors reported that
are >50 or more. When I see that, I run profcheck, find the patch with the
maximum error, then re-read that patch and put in the new result, then
repeat as necessary. Presumably, if one patch reading is wrong, it will
affect the errors on adjacent patches as well, so is this a sensible
approach?
Also, are you aware of any third party software that can drive the
SpyderPrint colorimeter?
The profiles that I have produced with Argyll seem to be more consistent
across different papers than the ones produced by the Datacolor software,
but I haven't done too much printing with them yet - it has been an
interesting learning experience though!
Best wishes
