Benefits of technology

The patent text is explaining a new technology for improving the efficiency of solar cells. The technology involves a special coating that helps to reflect sunlight and reduce its loss when the light passes through the cell. This results in a higher conversion of sunlight into electricity, leading to a more effective and efficient solar cell.

Problems solved by technology

The curved surface shape of the lenticular lens is difficult to accurately form in high resolution by using an inkjet printer as discussed in PTL 1.

Abstract

The present invention is directed to obtaining an object having an anisotropic reflection characteristic without using a lenticular lens. A print product including a print medium on which a repetitive structure of projected portions and recessed portions is formed out of image forming materials including a color material includes a first layer formed on surfaces of the projected portions out of a first color material among the image forming materials, and a second layer formed on the recessed portions out of a second color material different from the first color material, wherein the projected portions have a height to occlude part of the second layer when observed at an angle different from an angle formed by a normal to a surface of the print medium.

Description

TECHNICAL FIELD[0001]The present invention relates to color reproduction of an object that changes in color depending on a direction of observation.BACKGROUND ART[0002]Woven fabric, typified by velvet, has a fine complicated shape on the surface and thus has an anisotropic reflection characteristic of changing greatly in appearance as the angle of observation changes. A lenticular lens can be used to provide a typical anisotropic reflection characteristic. PTL 1 has been discussed a technique for simultaneously forming a lenticular lens and an image adhering to the lenticular lens by using an ultraviolet (UV) curing inkjet printer that can discharge ink containing a light curing resin to form arbitrary projections and recesses.[0003]According to the method using a lenticular lens, to smoothly change color with a change in the angle of observation, the adhering image needs to be printed in high resolution. The curved surface shape of the lenticular lens is difficult to accurately for...
