The adhesive strips are 10 mils thick and the paper is 8 mils thick with the tape being positioned on a top portion only of the paper. This creates uneven stack issues in the feeder of the printer that prevents proper feeding of the sheets into the printer. These issues are eliminated by providing taped media imposition that orients the PSA to signage card color bands which are imposed in a mirror image. Mirror imaging of indicia on the card color bands evens out the sheet stack and enhances sheet feeding.
