The high viscosity of UV inks often causes blade streaks and misting during transfer from anilox rolls, leading to speckle defects on printed surfaces. At speeds exceeding 150 meters/minute, friction between doctor blades and anilox rolls intensifies, significantly increasing scratch risks.
Chemi Tech's KMR-3001 Anti-Scratch Address addresses these issues through rheological modification:
Dynamic Viscosity Control: Reduces ink thixotropy to improve shear flow in blade contact zones;
Surface Energy Optimization: Fluorinated compounds minimize ink residue in anilox cells, preventing blade buildup;
Micro-Defect Repair: Fills micro-cracks in ink layers during curing for enhanced smoothness.
Case Study: Label Printer Efficiency Breakthrough
A flexo label manufacturer encountered 4-5 annular scratches per shift on PET labels, requiring and generating 50+ meters of waste. After using KMR-3001:
Added at 1.5% of ink weight, scratch frequency decreased 80%;
UV ink mist spots reduced by 70%, lowering rework costs;
Anilox roll polishing intervals extended from 2 to 8 weeks.
KMR-3001 is compatible with rotary and label presses, maintaining print gloss while drastically reducing waste. Chemi Tech upgrades printing stability through advanced surface treatment.
