I first did this design about two years ago. No problems. No complaints.
Then I got my new computer, and printer. A printer that uses different ink than I used to. These days, I would say that at least 15% of my 'work' time is spent on adjusting colors.
I thought I had it. For several months I sold, printed and shipped out garments with my Batgirl design. I got reviews and thank you's from my customers. Then I got a review that crushed me. (I take my reviews very seriously) It said that my Pink looked more like Salmon. I took a good look at it, and..it did.
