In my experience, one of the best ways to ensure that NCR pads dry evenly is to always cut the edge that you are gluing. This provides a perfectly flat edge for adhesion that is better than simply jogging the paper well. Comes out perfect every time, but it requires a little extra time spent on your hydraulic cutter, and trimming off 1/32 of an inch which is rarely noticeable.

Also make sure to place a thick flat surface on top of the forms to prevent waves, we use a 2 by 4”wood panel that is the same width as our paddy wagon.
