Back printing is printing on the reverse side or back side of a carbonless form. The print is usually lighter in shade or a percentage of the original color of ink. The lighter shade of print is done so the back side printing does not bleed through to the front side of the custom carbonless form.
Back printing can be printed head to head the top of the front matches the top of the back for or it can be printed head to foot were the top of the page for the back is bottom of the page on the front. Back side printing can be done on most forms and printed material and is not limited to carbonless forms.
We use back side printing on note pads, letterhead, envelopes, flyers, and many other products. Back printing can be printed in all PMS colors but is usually done as a 50% screen of black to look like gray ink thus the lighter shade of ink.
