My example of a printing mistake is mis-registration. Mis-registration occurs when the successive passes of a printed sheet through a press do not correctly make contact in the areas that they were intended to. One problem that could lead to this is changes in a paper’s dimensions (like stretching due to not lining it up correctly in a tray or having damp paper being incorrectly outright as examples).
As seen in the attached image, the letters in the word “East” look as if they are shifted the left and to the right even though the letters proper are somewhere in the middle. Since the alignment is not correct due to a likely scenario involving paper stretching during a print job, the result of this print sample is mis-registration.
