Suggestion: The article should have a discussion of image embossing algorithms in terms of computer graphics, and how embossing algorithms work.
The article says that embossing is done on letterpresses, which is true, but it is also done in conjunction with engraved printing. In those instances, is a letterpress also used? If not, then the article is misleading. —Preceding unsigned comment added by Jimstoic (talk • contribs) 18:29, 10 November 2010 (UTC)[reply]
