A common question asked by our customers, What are paper coatings? And how are they used. When samples are available it helps to explain the feel and characteristics of them. But it is not always possible. So I am going to setout and try to explain what coatings are so you can get a better understand of the characteristics of each.
Below is a list of Different Coatings and their characteristics: Note Coatings can only be used with certain type of stock. When you are planning your printed project ask if the stock allows for coating options. Warning - Coating projects may increase the likelihood of cracking when folded and scored.
