I am redoing the profiling of the papers i provide to customers since i have added another printer.
When profiling papers with larger OBA contect, i used the OBC function of I1Profiler-1.5.6 icm with a i1 Pro2 spectrophotometer.
I got strongly variing results, which made no sense, giving rise to a lot of frustration,
So i did a simple test: measure a chart, create the OBC chart, select a value in each of the four columns and then proceed to create a profile, with M0 as condition.
Then in the profile creation screen changed the name of the profile to create and pressed the create profile button again, in total i did this 6 times in succession with the same opened data, with no changes to the data or obc settings.
Then viewed the profiles in a profile viewer (DocBees profile manager) with the on-sight media selector tif as data to plot on the profile. Profile gamut is shown in absolute colorimetric setting.
The BAD thing: each profile created is different! (Added screenshots: first 3 are from a series of 6 created in succession, the last one is with condition m1 and the second created in succession with condition set to m1)
Differences in tone curve are significant (mainly the b dimension), also the white point "height" in L* dimension variies per created profile.
I repeated this, also saved the measurement and the workflow as well before creation of the OBC chart, so i can open it to get back at that point in the workflow.
So i opened the saved workflow, i created the OBC chart etc, and profile created is different again!
When i choose a different condition (M1 or M0) i get also very distorted profiles, especially the tone curve, also with some sort of ondulation now in the top part of the profile gamut envelope.
After stopping and starting iProfiler, i open the saved workflow and now the patch sizes are defaulted, so not the sizes used and saved as such. Also it defaults to an Isis (i have no Isis), whereas it was saved with i1 Pro selected. This did not resolve the problem.
Also it does not ask for selection of the condition (M0, M1) during the first profile creation, it just creates the profile. When i create another profile in succession it then asks to select a condition.
Conclusion: The OBC functionality in iProfiler is very badly implemented by X-Rite, how this has got past their testing and quality control is beyond my comprehension (test took about 15 minutes), assuming they do test and control quality.
And i cannot reproduce the OBC correction like i have in the profiles for my other printer,
nor can i reproduce anyhow with consistent quality.
Has anyone experienced the same problems?
If so, how did you resolve or by-passed the problem?
What is a good alterative to the OBC solution of X-Rite?
