Seems like a good way to learn, since a profile for that ink/printer/paper combo comes bundled with QTR, and I can ultimately compare my profile with the bundled one. Good theory, at least.

However, in the K7 inkset I am using (Special Edition) channel #5 is far more dense than #4 or even #3. Effectively, there is no crossover with the previous channel. All of the other channels do have a crossover limit.

  JB,

When you say K7 inks are you using the Piezographic K7 inks from the Ink Jet Mall?  And if you are, do you have them loaded in the slot sequence that they recommend?  eg slot 1 for shade 1, slot 2 for shade 2, slot 3 for shade 4, slot 4 for shade 7 etc.
If you do, then as I understand from Jon Cone, you cannot make your own profiles.  They have some special ways and equipment to do it.  I use their K7 Special Edition inks and use their profile that come with QTR.  With the 4880 printer you can use any of the profiles for Epson printers in the series with  x880 designation.

Hope this helps.
