As with any printing papers, PaperTyger printing papers should be allowed to become fully acclimated to pressroom conditions before attempting to use them. PaperTyger papers are manufactured to a relative humidity of 42-50% @ 72°F / 22°C.
As relative humidity is a function of temperature, the first step is to be sure paper reaches the temperature of the pressroom before opening any packages, cartons, or skids. Use this paper conditioning chart as a guideline for how long, e.g. cold paper might need to reach the temperature inside the pressroom.
