Troubleshooting - Matchprint Analog Negative/Positive Proofing Systems
Poor Image Quality
Q: Water rinse temperature too hot/cold
A: Adjust water rinse temperature to within five degrees of the preferred range. Too cold water causes poor cleanout, and too hot water creates color wash out. We recommend a water mixer in the water line to the processor if possible. Water mixers can be purchased at graphic arts supply dealers or through your local plumbing company.
Use the Matchprint Model 2570 Water Recirculator to help regulate water temperature.
