Abstract

Provided by the present inventions are a pattern-printed sheet and a method for manufacturing this, wherein the pattern-printed sheet is characterized that on a precoat layer laminated on a substrate are formed an optically readable region in which a dot pattern optically readable by an input terminal is printed and an optically unreadable region in which a dot pattern optically unreadable by an input terminal is printed, and the dot pattern formed in the optically unreadable region is a halftone tint having regularity whose halftone dot concentration is in the range of 10 to 30%. This pattern-printed sheet not only can be obtained by using a gravure printing method having outstanding production efficiency but also has a dot pattern readable with high reading precision in a prescribed dot size.

First claim

The invention claimed is:

1. A pattern-printed sheet, comprising:
a substrate;
a precoat layer laminated on the substrate;
a first region printed on the precoat layer and comprising a first dot pattern in which a pattern in one part differs from a pattern in another part such that locations of dots in the first dot pattern can be identified from a lay-out relation of the dots in the first dot pattern that is optically readable by an input terminal; and
a second region printed on the precoat layer adjacent to and not overlapping the first region and comprising a second dot pattern, different from the first dot pattern, in which the dots are arranged in order such that locations of dots in the second dot pattern cannot be identified from a lay-out relation of the dots in the second dot pattern by an input terminal;
wherein the second dot pattern comprises dots arranged in order and is a halftone tint having regularity whose halftone dot concentration is in the range of 10 to 30%.

2. The pattern-printed sheet according to claim 1 , wherein a plurality of the first regions and a plurality of the second regions are formed alternately.

3. The pattern-printed sheet according to claim 1 , wherein the dot pattern formed in the first region has the dots with the diameter of 80 to 130 μm and with the dot density of 5 to 20 dots/mm 2 .

4. The pattern-printed sheet according to claim 1 , wherein the pattern-printed sheet comprises on the substrate: the precoat layer, a dot-printed layer, a primer layer, and a surface protective layer comprising a crosslink-hardened curable resin composition in this order; wherein
the precoat layer comprises a resin composition comprising titanium oxide and at least one resin selected from a polyurethane resin and an acryl polyol resin, and
surface wet tensional force of the precoat layer is in the range of 30 to 60 mN/m as measured in accordance with the method stipulated in JIS K6768.

5. The pattern-printed sheet according to claim 4 , wherein the dot-printed layer comprises a vinyl chloride/vinyl acetate/acryl-type copolymer resin which contains carbon black.

6. The pattern-printed sheet according to claim 4 , wherein the primer layer comprises a hardened two-component cure type urethane resin.

7. The pattern-printed sheet according to claim 4 , wherein the surface protective layer is a crosslink-hardened resin composition of a resin composition curable by an ionizing radiation beam.

8. The pattern-printed sheet according to claim 4 , wherein the curable resin composition contains a filler in the range of 0.5 or more by mass to less than 12 parts by mass relative to 100 parts by mass of a curable resin.

9. The pattern-printed sheet according to claim 4 , wherein 60° gloss value thereof is in the range of 10 or more to 75 or less.

10. The pattern-printed sheet according to claim 1 , wherein the first region comprises reference points arranged in parallel in vertical and horizontal directions, the dot pattern formed in the first region comprises dots displaced from the reference points.

11. The pattern-printed sheet according to claim 1 , wherein the first region and the second region are formed contiguously.

12. The pattern-printed sheet according to claim 1 , wherein the first region and the second region are formed with a space therebetween.

13. The pattern-printed sheet according to claim 1 , wherein, in the first region, reference points are set up in parallel in vertical and horizontal directions with the same distance, and the dots of the first dot pattern are displaced predetermined distances from side to side and up and down from these reference points, whereby locations of dots in the first dot pattern can be identified by a relative location relation from the reference points of the dots.
