Hi Graeme Gill! I am very found of your work you put into ArgyllCMS. I bought a 2nd Hand EFI ES-1000 Rev. D with a UV Cut Filter for a low price (~200USD) I tried to create a easy workflow solution for me, I have several Epson Printers all of them are equiped with refillable cartriges and third party inks. Since there is no Custom ICM Profile I had to create my own, before that I rent a ColorMunki for about a week but I did want to own a spectrometre myself. I print 870 Patches on a sheet of A4 Paper. 90 Patches are for B/W. Since the EF ES-1000 is a relabeld Eye-One it works good so far. These are the commands I use for the workflow targen -v -d2 -G -g90 -t -f870 "870_A4" printtarg -v -ii1 -a0.82 -b -T360 -P -m1 -pA4 -L "870_A4" chartread -v -H -B -T0.4 "870_A4" colprof -v -qh -S AdobeRGB1998.icc -dpp -D"PRINTERMODELL INKSET PAPERTYPENAME" "870_A4" Do I have to change anything due to the UV Cut Filter? I want to print photos as neutral as possible. Is there any tweak that I didn't see or forgot? Kindest regards from Hamburg Germany Serhat
