Wow - are Estonians printers that advanced and that sensible?
Here printers always insist on some ICC profile, usually some utter crap which turns red to grey and yellow to red before they accept work. Sometimes photographers also supply their very own profile, carefully worked out to look right on their 1987 Sony Profile monitor. Then you're fucked. And guess who gets the blame?
Yes, the pre-press dogsbody, who could correct all the faults and mishaps before they happen, but who only ever gets to correct the damage after it happens.
