C2S coated

C2S coated: "Coated 2 sides" cardstock — a clay coating applied to both faces for sharper printing and a smoother feel.

C2S (coated two sides) means the paper has a thin clay coating applied to both faces before it ever reaches the press. The coating fills in microscopic surface fibers, giving printers a smoother, more uniform sheet to lay ink on. The practical result: colors come off the press more saturated, blacks deeper, fine type and hairline detail hold their edges instead of bleeding, and metallic foil sits flat instead of skipping over surface texture. C1S (coated one side) is its cheaper cousin and is fine for the inside of a tuck box, but C2S is the right call for any surface a customer will actually see and handle. Mr. Playing Card tuck boxes are printed on 350 GSM 16 point C2S coated cardstock so brand colors and gold/silver foil sit flat and consistent across the run, and so embossing crisps up without cracking the coating. If your artwork includes large solid areas of a Pantone-matched brand color, C2S is what keeps that color consistent from the first box off the press to the last. C2S also accepts soft-touch lamination, spot UV, and aqueous coating cleanly — none of which behave well on uncoated stock.
