Abstract

PURPOSE:To obtain double-surface printed matter in one process by using a single surface printing press, by a method wherein a printing layer for a front surface and a printing layer for a back surface are formed to the single surface of an object to be printed by printing and one of both layers is adhered to the other surface of the object to be printed in winding up the same. CONSTITUTION:Picture patterns 11 which must be applied on the surface of a final product by printing are printed on the surface of a long object 1b to be printed withdrawn from an unwinding roll 1a by using the first unit 2, the second unit 3 and the third unit 4 in a multi-color gravure rotary press for single printing. These picture patterns are printed by using inks each having strong adhesiveness. In the next step, a release layer 12 having strong adhesiveness is printed to the surface of the ink layers or the object to be printed by using a fourth unit 5 and, thereafter, picture patterns 13 which must be printed on the back surface of the final product are printed by using a fifth unit 6 and a sixth unit 7. Subsequently, an adhesive 14 is applied by using a seventh unit 8 and, thereafter, the object to be printed is wound up around a wind-up roll 9 while contacted with the surface of a press roll 10 under pressure.

方法を提供しようとするものである。Conventionally, 1 In order to produce double-sided printed matter, 1 When using a normal single-sided printing machine, the front side of a long printed material is printed and rolled up, and then this rolled up material is processed in a manner suitable for printing on the back side. It required two steps in total: resetting the paper and printing on the back side. In order to perform this in one step, it was necessary to use a double-sided printing machine equipped with a reversing device for reversing the front and back sides of the printing material. The present invention aims to provide a method for obtaining double-sided printed matter in one step using a conventional multicolor gravure rotary press for single-sided printing.

法である。In other words, in the present invention, the front printing layer and the back printing layer are printed on one side of a long printing substrate so that the front printing layer and the back printing layer can be separated, and in this case, The uppermost layer of the printing layer is adhesive to the non-printed surface of the printing material, and the uppermost layer of the printing layer is then rolled up by winding up the printed long printing material. A printing layer printed on the upper layer of the front printing layer or the back printing layer that is separably formed on the non-printing surface of a long printing material by closely contacting the non-printing surface. This is a method for producing double-sided printed matter characterized by transferability.

As shown in the cross-sectional view of the multicolor gravure printing machine in Figure 1 and the intermediate product in Figure 2, the surface of the final product is The pattern to be printed (at 1°C) is printed using, for example, 6 units of 1st unit (2), 2nd unit (3), and 3rd unit (4). Printing is performed using ink.Next, the fourth unit (5) is used to print a release layer 02) having strong adhesiveness to the ink layer or the surface of the printing material. Next, a pattern (13) to be printed on the back side of the final product is printed using the fifth unit (6) and the sixth unit (7). The ink used here needs to have mold releasability with respect to the mold release layer. Next, apply adhesive (14) using the seventh unit (8),
Next, the printing material is transferred to the take-up roll (9) and the pressure roll (1).
Wind it up while pressing the surface with 0). The adhesive needs to have adhesive properties to the back side ink layer and the back side of the printing object. In this embodiment, the pattern layer and the release layer (
12) constitutes the front printing layer, and the pattern (13) and adhesive (14) constitute the back printing layer.

ッキング性の良好な印刷物が得られる事（でなる。The printing material wound up in the above manner is pressed by the pressure roll while the printing layer formed on the surface and the back surface of the printing material are in close contact with each other, so that the print material is released by the action of the adhesive that is the topmost printing layer. The printing layer for the back side printed on the layer is transferred to the back side of the printing material, resulting in a double-sided print (1) as shown in Figure 3.
5) can be obtained. In addition, in the above-mentioned method, the surface printing layer may be only a release layer. In this case, for convenience of explanation, we used the term "printing layer" on the front surface, but if you turn the printing material over in advance, you can obtain a printed material with good blocking resistance and a pattern on the surface with only the release layer on the back surface.

て接着性を有する場合には接着剤層は省略できる。Further, regarding the pattern layer of the back side printing layer, if it is desired to fully exhibit the releasability between the back side pattern ink layer and the release layer, a release layer may be provided between the two. In this case, the release layer also serves as a protective layer for the back pattern layer. Furthermore, if the ink layer for the back side pattern itself has adhesive properties to the back side of the printed material, the adhesive layer can be omitted.

As a special application, when the printing layer for the back side is only an adhesive layer, a printed product having an adhesive layer on the back side is obtained as a product.

A pattern for the surface using Uninoto and salt-vinyl acetate resin gravure ink? After printing, a release layer containing silicone resin as a main component was provided using a flat 4 unit. Next, apply a layer of acrylic resin-based release varnish using Uma 5 Uni 7), and then print the pattern for the back side using Uma 6 Uni No 7).
Using Uninotna, a salt-vinyl acetate resin adhesive was applied and rolled up in a semi-dry state. During winding, a pressure roll was used to ensure that the front and back surfaces of the printed salt f-vinyl film were in complete contact with each other. When the printed material that had been rolled up was rewound, a double-sided printed material was obtained in which the release varnish layer, the printed pattern layer for the back side, and the adhesive layer were integrally transferred to the back side of the PVC film.

After the film was completely coated with adhesive, an A7 unit was used to apply the adhesive and the film was wound up. The adhesive layer is transferred to the back side of the vinyl chloride film G,
As a result, an adhesive-backed tape was obtained.
