Microprinting

• ... that microprint was invented by Albert Boni in 1943?

• ALT1:... that microprint can be found not only on currency but also bank cheques, postage stamps, security seals, and other important documents?
• ALT2:... that the first US postage stamp to incorporate microprinting was the American Wildflower Series in 1992?
• ALT3:... that true microprint (text less than 1px tall) can not be reproduced by digital methods but microtext can (text approx 4 to 1px tall)?
• Comment: I have spent the past few days significantly expanding and improving this article.

5x expanded by David Condrey (talk). Self-nominated at 09:09, 8 October 2015 (UTC).

• I will review this one.... Hassocks5489 (Floreat Hova!) 19:50, 12 October 2015 (UTC)

• There is some further work needed here. An expansion of about 2.5x has been achieved so far (based on expansion starting on nomination date of 4 Oct), and a large number of good sources have been introduced, but more content is needed to reach the DYK yardstick of a 5x expansion. There may be scope to include info about microprinting on other countries' banknotes, for example. There is an {{Expert-subject}} tag in one section, which I think is justified, but some expert help would really need to be forthcoming before this could run at DYK. Has the Science wikiproject been approached directly? Could the Numismatics and/or Technology wikiprojects help as well? There are also some paragraphs needing citations.

This article has excellent potential, especially given that good sources have been added as part of the expansion so far, and it would be good to keep this nomination on hold for a while to see if further expansion could be achieved. I have watchlisted the article. Hassocks5489 (Floreat Hova!) 20:41, 12 October 2015 (UTC)

I have noted this article is currently being peer-reviewed, so am prepared to continue to keep this nomination on hold for the time being. Hassocks5489 (Floreat Hova!) 12:22, 23 October 2015 (UTC)
