However, the Topps employee I spoke to told me they used offset lithography printing - ie a printing plate created from a mask of negatives (I'm following Steve's theory here that an obstruction - tape, etc- in the platemaking process prevented the black plate from being properly exposed). In gravure a cylinder is engraved with cells which carry ink - seems a lot different than offset lithography. Also, it says gravure prints hexagons, while offset lithography gives the dot design - an example of which can be found on the very distinct 1990 Topps colored borders.

Well I'd say the point of the post is not to demonstrate that a gravure method was used vs. offset lithography and that the references to gravure, by means of internet ready information, were the clearest way to demonstrate the idea of how printing made the leap from etched images to being able to accurately reproduce photographic images on a plate. I would trust your assertion regarding the use of offset lithography.
With either offset lithography or gravure (in 1990) a chemical process is required to transfer the image from the negative into a metal plate. Full stop.
My point being this is my opinion on where the error originates. It was a chemical issue that relates to the image being engraved on the plate. How the ink and/or image is then impressed or transferred to cardboard stock is not an issue.
This would correlate with the visual we have from the totality of the error area. It resembles nothing. It is an irregular fluid area, almost like you poured water on a pane of glass.
I do not understand the desire to relate all this to a piece of tape or cardboard obstruction, which the error area in no way resembles.
Perhaps it's a better narrative that more people could relate to that a careless or incompetent worker carelessly or foolishly wasn't paying attention to a piece of tape or cardboard, rather than a very esoteric discussion of offset lithography methodology and common mass production issues.
