What is the difference between 14 pt. c1s and 14 pt. c2s?

14 Point paper refers to the exact thickness of the paper at .014 inches or 0.356 millimeters. This is equivalent to 114 Lb. card stock or 308.52 gsm.

C1S = Coated 1 Side
C2S = Coated 2 Sides


A coated paper stock is usually either glossy or matte. An uncoated paper stock has a similar texture to a piece of photocopy paper, which is uncoated. So a C1S paper might be glossy on one side, and uncoated on the other side.
