Abstract: In a method of printing a product, a plate gap can be at least partially concealed, and the presence of any trap lines can be minimized. The background of each impression can be printed to include a gradient region along the leading and trailing edges of the background adjacent to the plate gap. An overprint ink/layer can be printed over the plate gap and at least a portion of the background gradient regions. The overprint ink/layer can be printed to include gradient regions along the leading and trailing edges of the overprint. The overlapping gradient regions of the background and of the overprint soften or obscure the appearance of any trap lines that would otherwise be more prominent in the overlapping areas.
