Pro tip: I spent 4 months chasing a muddy green in my t-shirt runs before I found the real problem
I was trying to hit a bright grass green on some cotton tees and the color kept coming out olive brown instead. I adjusted the ink mix, tweaked my curves, and even swapped paper stocks for weeks, but nothing worked. Turns out my printer's magenta cartridge was low and the software was quietly swapping in a duller profile, so my whole "green fix" was built on a bad baseline. Took me about 4 months of guessing before a guy at the supply shop in Akron asked if I'd checked my consumable levels first. Has anyone else had a bad cartridge throw off an entire color plan like that?
