Note: 1. This thickness is added by multi single-ply papers, and it is only achieved when
just printing on the upper paper. (No need to copy)
2. Refer to the requirement of the multi-ply paper (NCR paper), the mount paper can
be thicker than other plies, but we can’t guarantee the printing effect as it is
influenced by paper difference.
