Methods for measuring printed materials

Abstract

To provide a printed matter capable of improving a quality of a pattern in the printed matter capable of recognizing a displayed content through the pattern, a display device, and a production method of the printed matter.SOLUTION: A pattern-printed layer 5 can conceal the existence of a light source with a pattern when the light source is turned off. Therefore, a pattern of the pattern-printed layer 5 is shown on a printed matter 50. On the other hand, light from the light source can penetrate the pattern-printed layer 5 when lightening the light source. Thereby, a pattern on a front side is visually recognized when a light source from a back face is not lightened, and a displayed content of the light source can be visually recognized through the pattern when lightened. A first graph of a value has a mountain-shaped peak, and a second graph of b value has a mountain-shaped peak when measuring the a value and b value of reflected light from an arbitrary measurement place of the printed matter 50 by a range of a receiving light angle of 0-30 deg to make a graph.SELECTED DRAWING: Figure 41

Claims

[Claim 1] It comprises at least a translucent substrate and a pattern printing layer, The aforementioned pattern printing layer is provided on one side of the translucent substrate and includes a pattern layer composed of a plurality of dots. Each of the aforementioned multiple dots comprises a binder and a plurality of pigment chips dispersed within the binder. The plurality of pigment chips are interference pigments, and the method for measuring printed materials is as follows: When the a-value and b-value of reflected light from any measurement point on the aforementioned printed material are measured within a light receiving angle range of 0 to 30 degrees and a graph is created, A method for measuring printed materials, which evaluates whether the first graph of the a value has a bell-shaped peak and the second graph of the b value has a bell-shaped peak.
