I have printed about 30 wraps for one of my customers. The main color is red and burgundy. I printed one whole wrap a couple of nights ago without a problem. The following night I printed 3 sections with no problems, but when I printed the bulk of the wrap 5 minutes later, the color seems to be a lot more brown than it should be. This leads me to believe that the Magenta is not laying down enough ink all of the sudden. I have done numerous tests and nothing seems to be working. Printheads are new., primer tips are there, etc. Any ideas?
