What we should know about Measuring Paper Moisture?

Moisture content gets measured as relative humidity (RH), and most papers are designed to be stable at 45-55% RH in a 72°F environment. Typically, manufacturers produce paper to an absolute moisture content between 4.0 and 6.0%, meaning water makes up 4 to 6% of the paper’s total weight. But once unpacked, paper can either absorbContinue reading “What we should know about Measuring Paper Moisture?”
