Blocking Blocking can occur where ink from one print is deposited on the back of another when prints are allowed to accumulate in a
stack in the output tray. The combination of pressure from the weight of the media and ambient heat may cause partial transfer
of the image to the next print in the stack. Blocking is aggravated by abrasion, vibration, or storage under a large stack of prints
(compression). See also residual image.
