What is C1S and C2S in Printing?
C1S is printing industry shorthand for "coated one side." Likewise, C2S means "coated two sides." These terms refer to coatings applied to paper by the paper manufacturer.
Why is Paper Coated?
Paper is coated to produce a smooth printing surface and to slow the absorption of ink. Basically, the coating acts as a barrier to help keep the ink on the surface of a printed sheet, as opposed to allowing it to seep into the paper fibers. This extra control results in sharper images and finer details.
Different Coatings Yield Different Results
Coatings can be glossy, matte or dull depending on the application and the desired effect. The more sheen to the coating, the more brilliant and vivid the ink colors will appear when printed. The duller the coating, the more subdued the ink colors will appear.
Don't Confuse your Coatings
Bear in mind that C1S and C2S refer to a coating applied at the paper mill before your printer gets the paper and prints on it. Thus, it is not to be confused with various coatings your printer may apply after the printing process, such as UV or aqueous coatings, varnishes or laminates.
