I'm successfully making RGB profiles for my printers, using a DTP22, argyll's targen and printarg (to create the target), Xrite's ColorPort software, the cpxchg utility to convert argyll ti2 and ti3 files to and from ColorPort and argyll's profile command. I'm reasonably confident that ColorPort and cpxchg provide a way for most Xrite instruments to feed into argyll. Many thanks to Graeme for his help in outline a method for debugging the workflow - this turned out to be key, as well as a Photoshop based procedure documented at InkJetArt.com. My next step will be to "tune" the profiles to get a more accurate gray ramp, as Graeme described in an earlier post, but that's for later. One remaining problem - the profiles I create are satisfactory, but for one of my printers the PCS value for black, Lab(0,0,0), yields an RGB value of RGB(13,8,2). This is very close to black, but measures as a slightly lower density than a max black. The profile is probably attempting to compensate for the rather cool black of this printer by adding red-orange. Is there a way that I can specify that black should map to RGB(0,0,0)?
