Slow Drying and Slow Setting

Paper pH

Paper should be between a pH of 6.0 and 8.0 Readings lower or higher than this range will affect ink drying

Paper absorption

A paper with low absorption will prevent the inks from setting up, and will slow down the overall drying of the ink film

Fountain solution

High acidity levels will retard the oxidation as will high levels of alcohol substitutes

Paper absorption

Lower the absorption. Slow the setting

Lifts are stacked too high

Run shorter lifts on heavier coverage jobs and ensure spray powder is dispensing correctly and is the correct particle size

Water levels too high and emulsifying the ink

Adjust ink/water balance to lowest levels
