mailto:argyllcms@xxxxxxxxxxxxx Hello Everybody, It's Diego I' m new to backlit printing and I' d like to make a good profile for this kind of printing on my A4 and A3 printer. I'd like to use Argyll to do this but I don't know what kind of option setting. I' d like to print not more than 2 A4(or legal) pacth sheet, is it enought to make a good profile? 2 legal profiles give me 504 patch. Another point is that I tried to use the chatread command with -e (emissive) option but Argyll continue to make 2 beep on reading.This because probably I have to set the -T ratio option but what to put? Perhaps I' m using the wrong command and I have to use the filmread command. What to do? I hope someone could help me.:) And I hope to obtain good results with Argyll. Thanks for any help.Have a nice time.Diego
