Is there, by any chance, any parameters I could type on the command line for creating output profiles, whereby I could limit the minimum dot size used to convert B2A? The application I'm dealing with, flexo, can only deal with dots greater or equal to 2%. An 1% dots have to be deleted, painstakingly, in Photoshop through selections techniques or levels. Let me add as a further constraint that areas of 0% must be preserved.
Is this possible today with argyll? Or am I pushing the enveloppe?
It's not possible as things stand. Such a thing is probably best handled at a calibration level (applying per channel device curves after the profile), but this involves some considerable work (ie. it's on my wish list). I did add a feature to limit maximum K, and while this works, it has a great impact on profiling speed, and also should probably be removed to a calibration function.
I'm not sure though, how a discontinuity such a you are suggesting, could be handled within the profiling loop. In theory it might result in color artefacts ?
If this is such a special case for flexo, why can't it be incorporated in the imagesetted RIP transfer curves ?
An alternative might be to directly edit the B2A table device curve tags, if a suitable editor is available.
[One could write code to do this, but it is such a special case, it's hard to justify, and a general tool is a lot of work.]
