For photographic prints at PCL we prefer sRGB or adobe 1998. For Online Orders use sRGB.
Q. what is the difference between colour spaces?
A. sRGB is very close to the gamut of photographic paper. Adobe RGB and ProPhoto each have a colour gamut that is larger than that of photographic paper. Our output ICC Profiles (made in-house) render both colour spaces to be indistinguishable from each other.
