PRINTING LIQUID CONTAINING SHOKOSEKI, PRINTED MATTER BY USING THE SAME, AND METHOD FOR PRINTING

摘要

PROBLEM TO BE SOLVED: To provide a printing liquid utilizing Shokoseki (a kind of quartz porphyry) and capable of generating negative ions, a printed matter using the liquid, and a method for printing using the liquid. SOLUTION: In this method, the printing liquid at least contains a Shokoseki powder 22, and it is used for preparing printed matters 11. Powdered Shokoseki is borne in an ink 21, and the radiant energy of Shokoseki generates negative ions. For printing, the printing liquid containing the Shokoseki powder is applied to screen printing or pad printing. In this way, printing may be performed not only on 2D shapes but also on 3D shapes, wherefrom negative ions can be emitted.
