Content-changing document and method of producing same
摘要:
Sheet print media are printed/marked with both transient and permanent marking which may be juxtaposed or the transient marking overprinted to change the meaning or message of text on the appearance of an image over time. Applications include advertising and labels for articles of commerce. The method applies to plain paper or coated print media for subsequent ultraviolet radiation.
