There was a proof stage somewhere between the ocr garbage and the final glyphs that were positioned on the screen. Having taken quite a few of the topaz books apart myself, it's clear that avoiding proofing was not a universal dodge by any means. I had several topaz books that actually rendered (and read) beautifully. Searching for text in the books was miserable, however, since it searched the included, but invisible ocr layer. The final product (glyphs positioned on the screen with some sort of coordinate system) was utterly unusable for searching or conversion to other formats.
The only conversion routines ever produced had to rely upon the underlying, mistake-ridden, ocr as well. So the results were never pretty. There was simply no way to match the glyphs from the matrices to letters in order to reconstruct the text of the book.
