Hi Graeme, Thank you for researching this for me. The TID for a short chart created from the software that came with the DTP20 works fine for me on a 4x6, so I'm certain that it's capable. I like your charts because there are more patches per page on a 4x6 sheet. So I can skip reading the TID in tethered mode and start reading the chart directly? I didn't have a clue. That might be a useful note to add to your documentation for the DTP20 if you would for other folks. Would you like to see the target file for the first page of a 4x6 so you can see what a TID from ColorElite looks like? That might help figure things out. Thank you again for your support!
