People who work in printing sometimes have a tendency to toss industry-specific nomenclature around without regard as to whether those within earshot will understand or recognize the terminology — particularly, when talking with clients/customers about a project or a job. Hence, you might hear a printer utter “C1S” or “C2S” and wonder “What is the meaning of this secret code?” In this instance, C1S and C2S are shorthand terms (acronyms) for “coated one side” and “coated two sides” in reference to coated paper stock.
Coated Paper Stock
Paper can be coated with a variety of materials or polymers to create a smooth, non-absorbent surface. This kind of surface keeps ink from sinking into the paper fibers and spreading, which enables images and text to be printed with more detail and resolution.
Different Levels of Sheen
Coated paper stocks are available in a variety of sheens ranging from high gloss to a matte finish. High gloss finishes are the coated paper of choice when rich, vibrant colors are desired in the finished piece. As the sheen level decreases, colors will appear more muted and subdued. Hence, it’s always a good idea to consult with your graphic designer and printer to pick a sheen that will match your intentions/desires.
Pre- and Post-Print Coatings
When a printer uses the term “C1S” or “C2S”, they’re referencing paper stock that comes from the paper mill with the coating already applied. It’s important to keep in mind additional coatings — such as aqueous, UV, laminates, or varnishes — can be applied to a coated paper stock after it’s been printed. These additional coatings, also available in different levels of sheen, can further enhance the look and feel of the finished piece.
