QTR-Quadtone RIP

Terry, I assume you have used the 3MK curves where you have 3 cartridges filled with MIS (image specialists) matte black?  That is definitely a warm black.

I have played with what I call 1MK, and 1PK.  I have tried just using one cartridge with a custom curve, and that works pretty well.  I have not noticed any significant banding (which is the rationale for the 3 cartridges simultaneously).  You might like the look of the straight PK color balance.

Otherwise, you could literally do some custom blending.  You could add a little blue/cyan or red color to the black to create your own custom ink mix.  You could mix small batches of black ink with a few different percentages of color.  You might be able to judge the color balance using a swab of the ink on your paper.

When you get the balance you like, then fill a cartridge (or 3) with that mix and use the standard single color curve (e.g. 3mk).
