Gimmick expression medium producing method and data processing method for gimmick expression medium
11602918 · 2023-03-14 · ·

A gimmick expression medium producing method forms a gimmick expression medium 300. The gimmick expression medium 300 includes a retroreflective medium 1. A printing medium 301 placed on the retroreflective medium 1 includes a light-transmission layer 302. A gimmick print 303 which varies color of reflective light of the retroreflective medium 1 to produce a gimmick effect is printed on the light-transmission layer 302. The printing medium 301 is provided with a light-blocking layer 304 which partially blocks reflective light reflected by the retroreflective medium 1. The light-blocking layer 304 is composed of a white printing layer, and a reflection picture print 305 is printed on the light-blocking layer 304. The reflection pattern printing 305 and the gimmick print 303 are placed in adjacent to each other using a stripe-shaped (or dot-shaped) lattice pattern 306, printing which can be seen on a printed matter under normal illumination and printing which can be seen under light source such as flash light can be printed at one time (one-pass) by the same printer.

Pad transfer printing method for making colored contact lenses

The invention relates to a pad printing instrument comprising an ink supply system capable of control the temperature, viscosity and colorant concentration of an ink in an ink cup. Such controls are achieved by continuously adding and mixing a cold ink having a composition identical to the ink in the ink cup but having a lower temperature. The continuous addition of a small amount of a cold ink into the ink cup could compensate heat generated by the friction between the ink cup and a cliché and could minimize the evaporation of a diluent in the ink and change in the concentration of colorants in the ink and ink viscosity. The invention also relates to use of a pad printing instrument comprising an ink supply system of the invention for producing colored hydrogel or silicone hydrogel contact lenses.
