How do paper and cover or board stocks compare during the printing process?
Paper, cover and board stocks, or more commonly referred to as substrates, do respond quite different from each other. Moisture (humidity), temperature and other factors in the storage and pressroom must be maintained to a certain level. Even though a plant may be climate controlled, the changes of the outside atmosphere can play a big role in how a substrate may respond during the printing process. Especially in the drastic changes from cold, dry winters to hot, humid summers. Generally thicker cover stocks have fewer problems than thin text stocks. However, if pressure, ink and water settings are not correct, there can be problems with any type of stock, such as paper curl and stretch. Remember these are just a few variables that affect paper and other substrates during the printing process.
