Talk:Diffractive optically variable image device

Reverted edits
I reverted a sequence of edits today that replaced reference links to several different articles on the Kinegram websites with links to a single page on that site, which provided little information and did not serve as a reference to support all of the statements that cited the original pages. Many but not all of the links are dead. A reference to a dead link is preferable to an irrelevant link.

Archive.org is down at the moment. When it is up again we can try to replace the dead links with archived copies. Srleffler (talk) 03:54, 25 August 2022 (UTC)
