My definitions:

I split printing errors and cutting errors.

Printing errors

Ghost: a wet sheet transfer where the ink from one sheet migrated to another leaving a mirror image of what is on the source sheet




Registration Error: a misprint where one or more ink passes was misaligned, resulting in an offset print. Varies in severity





Missing Ink: self-explanatory





Wrong back/front or inverted back: where the sheet was facing the wrong way when one side or the other was printed.




Misaligned front/back: where the sheet slipped when one side was printed and the result is the correct front/back combo but not aligned



Wrong partial print: where one or more ink passes was made with the wrong image, usually resulting from the sheet facing the wrong way for fewer than all of the ink passes



Misprint: anything that isn't covered above

Cutting Errors

The printing is OK on both sides of the card and they are aligned; the cutting was bad. Varies in degree from a nuisance to collectible--for me the latter begins where the image on the next card is visible





Diamond cut: I see these mostly with Topps cards. where the card is a diamond shape



Scrap

Stuff that does not appear to have made it through the end of the printing process or into the product
