I am having trouble with colored blotches when printing large, 12", solid color backgrounds on a DTG HM1. The problem is when printing green backgrounds I get patches of just cyan and when printing pink backgrounds I get patches of just yellow. The patches are not in the exact same spots but are close in both location and size. I have verified the color fills are solid with no textures, replaced the printhead and all dampers with no change in appearence. No difference when printing from PhotoShop CS4 or Corel X4. No difference with Color Management disabled, set for software or set for printer. The wiper is clean and so is the capping station. A test pattern of 100% CMYK prints perfectly so the issue seems to be in the color blending. Any ideas?????
