<p>PROBLEM TO BE SOLVED: To form a stereoscopic image by heating stereoscopic image forming ink for printing stencil containing thermally expansible microcapsule and binder by a simple heating means. SOLUTION: A light is cast on a stencil print image made of ink containing thermally expansible microcapsule given by photothermal conversion material and binder. A light is emitted by a flash lamp or the like to instantaneously heat to foam the ink. The photothermal conversion material preferably contains 0.01 to 1.0 wt.% of total ink amount. The conversion material is preferably composite oxide containing oxide of carbon black or the like and/or tin, antimony or indium as main components having a particle size of 30μm or less.</p> |
