What are the specific effects of temperature on ink?
- As the temperature of the ink increases, the amines evaporate from the ink, causing the pH to drop and the viscosity to increase.
- Changes in pH affect color, viscosity, and process speed.
- Changes in viscosity will adversely affect ink adhesion levels and flow characteristics, affecting the ink film applied to the substrate.
- Inconsistent ink film transfer clogs plates and causes frequent production interruptions for plate and anilox washing.
So why InKomand – Ink Temperature Control?
- Minimal addition of chemical additives … reduced cost / inventory
- Viscosity and pH changes are minimized if not eliminated.
- Improved ink drying
- Faster settings and shorter washes in time
- Significant reduction in ink adhesion
- Significant reduction in downtime due to sheet jams
