Hello there, we have been using Sonora XP Plates for the almost a year now, but recently we been getting spots on them. We know it is not from our CTP, because we hang a blank (No image) plate and run a test. Our press is a Miller TP104 5 color, our chemistry are as follow, Roller Wash - VARN, Fountain Solution - Nova Fount FS 501 and Achol Sub - Pro Chem AS-R. Any suggestion as to where we can make adjustments or changes to solve this issue? Thank you in advance.
