Marco,
On the R3000 you adjust the platen gap through the printer menu screen. Begin by pressing the OK button then either Left Arrow or Right Arrow to the Setup Menu.
On QTR, you can name the curve anything you want but most folks use a combination of Printer-InkSet-Paper-Tone OR InkSet-Printer-Paper-Tone.
R3000-UCmk-UPPM5-Warm = R3000 Printer-InkSet (UltraChrome matte black) - Epson Ultra Premium Presentation Matte (UPPM) 5 Star - Warm Tone
If you are using the Photo Black = R3000-UCpk-UPPM5-Warm.
Hope this helps.
