Paper Training For Printers

Over longer periods of exposure, unprotected paper will equilibrate to the ambient conditions, so any extremes in environment should be avoided. High humidity, for instance, will cause paper to take on moisture and curl at the edges. Conversely, excess dryness will cause it to lose moisture and become brittle and tight at the edges. Either substrate condition can result in registration and wrinkling problems on an offset presses, or lead to image deletion on digital printers. To ensure optimal performance, paper should be stored under temperature- and humidity-controlled conditions that closely approximate the environment in which it will be utilized.
