Pre-linearization is what you are mentioning there.
Hmm, well it might be more accurate to say 'device customized target generation.'
Picky picky... :0) Well, "pre-linearization" is the name by which I have seen the procedure discussed so far, that is, before I got corrected...
There is so much poor terminology being used out there. I try to use the right terminology when I can because it can help avoid confusion in the long run. I can see some disadvantages to this approached when working with true RGB photo-printer's (Lambda, Light-jet etc.)
Have you seen any disadvantages from using this process? Most users of these machines will run (hopefully) a linearization strip through the built in software/hardware every morning or on a roll change of media. Surely if another MP linearization is taking place over this lin, the profile cannot be accurate unless the user goes through the chore of creating a new profile every time they re-lin and again re-lin in MP.
Ah ha! This is where poor terminology can lead to confusion. The MP linearization isn't actually a linearization. This step is used for "device customized target generation" which makes a better profile with better gray balance. Another point I should mention is that if these machines are linearization and profiled correctly you will not see the double black issue.
But that's often not the case unless you utilize MP's linearization process. The linearization process on these machines is often less than optimal. Nortisu's for example, *always* leave mageneta in the black point. Netlabs have blacks all over the place. Durst's usually linearize well but I have a few that regularly put a whole bunch of green in the blacks. If you have lab with all of these devices, the only way to make the print match is to utilize MPs device customized target generation process. There is no need to re-lin in MP because the devices own lin process is consistent, and will always re linearize back to the same, less than optimal state.
