You can't lower it (without screwing it up) but you can build profiles based on the same dataset with different numbers. > Do 'old school' printers have trouble printing a full range of black?

Not unless you use a Gravure printer.

Souvlaki > > So looking at PSR LWC (lightweight), only 90% black but HIGHER > max..360%! I thought that a Gravure process could only handle LESS ink > not more max...Can someone explain why this is? Gravure can routinely handle more ink, and frequently uses a lot less black - this yielda more vivid colour. The inks are much more viscous (thinner) and the dot's and priting process used in gravure is very different from offset. Don't mix up offset and Gravure profiles. > > Basically, the printers ideally want 340% max, 85% black.... If it's an offset press one can simply build new profiles with appropriate numbers based on the same dataset. > What is our > best option? ISO web or PSR Gravure? Is ti offset or gravure printing?

A revised profile will fix that - AND you will still be able to proof it correctly. If you tweak the profile (or the file) proffing will likely be off.
