Once I did a Christmas print that just would NOT print out correctly. It kept looking more blue than the shade of green that I had wanted. The monitor was calibrated. The printer normally didn't have this problem. I happened by Office Depot later that day, thinking it was my color cartridge. It just happened that an HP rep was there. I explained my problem to him, and he said that HP printers were programmed that if they detected a certain shade of green to dump more cyan in the ink. I went home, not buying the expensive cartridge. I adjusted the shade of green JUST a bit, and it printed perfectly. I suppose I'd stumbled onto the color of money. -K.
