Technical bulletins for industrial printing operations

Targeted engineering notes addressing common printhead and substrate variables.

Eliminating roll-edge cockling

Ink viscosity and paper porosity

Storage in humid climates

Adjusting pre-heater temperature profiles and take-up tension to prevent edge-curl on lightweight 31gsm coated rolls during high-speed passes.

Balancing microporous coating absorption rates with high-load heavy density CMYK ink limits to achieve 98% dye release without bleeding.

Managing moisture-barrier kraft wrapping and acclimatization intervals in 85% relative humidity facilities prior to master roll loading.

Maintaining strict 45-55% relative humidity across the print floor eliminates electrostatic static discharge and ensures consistent master roll tracking.
