<p>PURPOSE:To make a latent-image design appear or disappear or view it in a different color manner by viewing by the change of a visual angle by using offset ink and intaglio printing ink including a vehicle having a repellence and mutually having repellence and conducting operation so that intaglio printing ink is placed only onto sections except an offset design. CONSTITUTION:Offset lines 4, 5 are printed onto a printing medium 1 such as paper at intervals 6 by the offset ink of two colors. Intaglio lines 9 corresponding to the width of the sections 6, to which the offset lines are not printed, are formed onto an intaglio printing plate 7, and intaglio printing ink is printed onto the printing medium 1. Since ink having repellence is used as offset ink and intaglio printing ink at that time, intaglio printing ink 8 is attached onto the sections 6 having no offset line while intaglio printing ink 8 is not transferred on the offset lines 4, 5, and positional displacement is not generated in the low lines 4, 5 by offset ink and the intaglio lines 9 having height by intaglio printing ink and a precisely inserted print is acquired.</p> |
