Good morning.
I tried to create profiles to eSprint.
The first thing that we need is create a base linearization for each
paper and resolution. Without base linearization you can't use a ICC.
I use Best Color Proof to make this task. This software is for PC, and
the version for Mac (Designer Edition) can't create base linearizations.
I believe that important step is define correctly this base
linearization.
This is the way Best works.
I was talking with a trainer from Best and he said to me that eSprint
works with Colorsync to determine points in workflow that eSprint has
no option.
If the purpose of eSprint is drive HP, it make this task, but if you
want to create new ICC's to use with it, you will need others softwares.
Best regards
