Definitions for "Felt Side"
The top side of the sheet on the paper making machine; usually the preferred side for printing.
The top side of the paper, which comes in contact with the dandy roll and felts during the papermaking process. The bottom side of the paper, which comes in contact with the wire (forming fabric) or the papermaking machine, is called the wire side. The felt side of a paper may appear to be softer, while the wire side of a paper may have more "tooth." During printing, the softer texture of the felt side of an uncoated paper may pick up slightly more ink than the wire side of the same sheet, and the printer may have to adjust ink densities to compensate for this. Paper is generally packed and shipped as it is made: felt side up.
The smoother side of paper for printing; the top side of the sheet of paper in papermaking.
