I would always defer to you expertise on printing issues, Steve. I collect recurring differences in cards whether they are print defects or intended differences.
The latter would be my definition of a "variation" as opposed to a variant. But I include in my personal definition of a variation both changes specifically intended ( like the 59 traded or optioned cards) and changes not specifically intended but resulting from intentional changes in the printing process itself, such as the Mantle and numerous other DP differences, or stock changes, or the 62 green tints.
I assume the printers in 56 did not intend the colored line differences, but what did they do that resulted in them, in particular the several different ones that exist for the Williams card
