Hello From germany I want to convert an rather old but good Epson R265 Stylus Photo to an dedicated B/W Pigment printer. I already mixed inks as following Black: 100 % Photo or Matte Black Magenta: 100 % Light Black (LB) Cyan: 70 % Light Black (LB) + 30 % Light Light Black (LLB) Light Magenta: 50 % Light Black (LB) + 50 % Light Light Black (LLB) Light Cyan: 40 % Light Black (LB) + 60 % Light Light Black (LLB) Yellow: 100 % Light Light Black (LLB) THX to pharmacist from printerKnowledge.com for that but I feel unsecure. How would the workflow look like? Since If i would print a my regular 1512 Patches on two sheets of paper it cointains all "colorfull" information, I want to read only the brightness not the hue, since it would be all "shades of grey" any ideas?
