As the tutorial suggests, I ran colprof -v -D"Epson 3880 A" -qm -S /usr/local/Argyll_V1.3.2/ref/sRGB.icm -cmt -dpp Epson_3880_A Iccdump shows Rndrng Intnt = Relative Colorimetric On the other hand, a profile Epson provides for use under Windows for the same printer shows Rndrng Intnt = Perceptual Is this because relative colorimetric is the default? If I wanted to produce a profile with Rndrng Intnt = Perceptual, how would I do that? Use -Tp? -- Leonard Evens len@xxxxxxxxxxxxxxxxxxxxx Professor Emeritus, Department of Mathematics, Northwestern University
