Paper is normally received at the printing press in moisture proof wrappers. However when the reams are unpacked and exposed to temperatures substantially below the ambient temperature, the paper begins to absorb moisture from the surrounding air. This causes expansion, waviness and curling of paper resulting in misregister and creases during printing. Moisture also delays the drying of inks, leading to smudging and set off.Variation in moisture level during plate making affects the light sensitivity of the coating leading to variation in dot density.
