I still don't know if I'm using the right Pixl image. The one I found may have diagnostic help, but if so I haven't figured out how to access it. Thjere is something at the website about a notes tool when used with photoshop, but I am working under Linux and using gimp. There are some general comments about the gray scale, and that looks okay to me with my display calibration/profile. In any case, I am not asking anyone to diagnose/fix what is wrong with my setup. I am just asking what techniques/tools I can use to do that myself. > > > > On Tue, Mar 15, 2011 at 3:57 PM, Leonard Evens > <len@xxxxxxxxxxxxxxxxxxxxx> wrote: > > On Mon, 2011-03-14 at 20:36 +0100, edmund ronald wrote: > >> display and printer both need to be calibratef. > >> > >> calibrate the display, > > > > My display was calibrated/profiled before i began. > > > > I've read about calibrating the printer, but the recommendation is that > > I not do that until quite a bit later.
