LIGHT-REFLECTION/LIGHT-TRANSMISSION IMAGE SHEET AND METHOD FOR FORMING LIGHT-REFLECTION/LIGHT-TRANSMISSION IMAGE SHEET

摘要

In order to enable a natural and clear image to appear in both light reflection and light transmission usage modes of a light-reflection/light-transmission image sheet having front and back-side images (3, 4) overlying each other with a sheet-like base material (2) that is reflective and transmissive interposed therebetween, the density distribution of the back-side image (4) of the light-reflection/light-transmission image sheet is obtained by reducing a high-density portion (N1) that exceeds a set density α in the density distribution of the front-side image (3), to the set density α or a density close in value thereto.

1. A light-reflection/light-transmission image sheet that includes, on a sheet-like base material that has reflective and transmissive properties, a front-side image and a back-side image that overlie each other with the sheet-like base material interposed therebetween,
wherein the density distribution of the back-side image is a density distribution in which a high-density portion that exceeds a set density in the density distribution of the front-side image has been reduced to the set density or a density close in value thereto.
