Questions about Calibration Targets 2/2

Question 3.
When using Fiery Color Profiler Suite and you use the second option “use existing calibration target” to create a new profile you can create a profile which can be used across multiple engines (same model and manufacturer) but depending on the media the calibration target will not use the full density range. So you probably take the Color Editor of the Colorwise Pro Tools and lift the target for those colors which have a higher DMax with that paper. Is that a good practice? Or would you by doing so “mess up” the best possible result because you for example lifted Cyan to the DMax and therefore the whole color balance is out of sync?

Answer 3.
This is wrong. Asking a printer to deliver more than it can is useless; color in the range not reached is out of control. If you want all printers to perform the same, limit the goal to the smaller DMaxes. This way, all printers will have the same limited gamut, and the same profile will apply to all.

Question 4.
Does it matter which shape the calibration target curve has? S-Shape, linear, exponential, etc. or is it more important to make sure the system can print DMax and then the color management system will do the necessary corrections based on the calibration targets used. I have seen several calibration targets which were created by the Fiery Color Profiler Suite and now wonder if there is something like an ideal curve.

Answer 4.
This is absolutely right: “it is more important to make sure the system can print DMax and then the color management system will do the necessary corrections based on the calibration targets used.” There is not something like an “ideal curve”. The fact is that many different printer manufacturers have different “native” printer responses. Yet, most can deliver excellent results. We had many debates here. What is ultimately important is that the calibration target can be reached time after time.
