I would like to know if the LK and LLK inks are used in making color prints with the Epson 7800, when printing with the Epson driver and ICC profiles?
What I would like to do is put darker shades of black (like Epson PK or Cone Opaque Black) in the LK and LLK slots to give more UV blocking inks in the printer for a QTR profile for making digital negatives, but hesitate to make this change if it makes printing in color impossible.
