Abstract

PURPOSE:To express a pattern such as a detailed design or character in a low cost by applying the thick build-up printing of a pattern such as a design or character to the main body of a cover by screen printing using UV ink and solidifying the ink by the irradiation with ultraviolet rays due to an ultraviolet lamp. CONSTITUTION:A screen 2 made of Tetron or nylon is placed on the outer surface of an outer surface sheet 1 made of a thermoplastic soft synthetic resin and a required design 4 is applied to the outer surface of the outer surface sheet 1 by thick printing using the screen 2 and UV ink 3 and, thereafter, the thick printing part 5 is irradiated with ultraviolet rays by an UV lamp 6 to solidify the ink 3 and a pair of inner surface sheets 7, 7' made of a thermoplastic soft synthetic resin are superposed on the inner surfaces of both end parts of the outer surface sheet 1 and the entire peripheral edges of the inner surface sheets 7, 7' excepting the inner side edges thereof are welded to the peripheral edge of the outer surface sheet 1 to complete a note cover 8. As mentioned above, the thick printing part can be solidified in a state held to a built-up state by the strong surface tension of the UV ink.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to notebook covers, address books, schedule books, etc.
Pocket diary Concerning the manufacturing method of covers made of synthetic resin sheets, paper, leather, metal, synthetic resin boards, etc. such as binder files.

[Conventional technology]

Conventionally, this type of cover has been widely known in which the design and characters are given a sense of thickness by creating unevenness on the cover body by pressing or other means.

[Problem to be solved by the invention]

The cover described in the above-mentioned conventional technology has a thick texture in the patterned parts such as designs and letters, and the pressing process requires expensive stamping dies and pressing devices, resulting in a high cost. C,
Also, in places where the designs and letters were thin, where the lines were extremely close to each other, and where the lines were drawn, the unevenness was difficult to make out.

It is an object of the present invention to provide a new method for producing a cover that enables the display of elaborate designs, letters, and other patterns at low cost.

[Means to solve the problem]

In order to achieve the above object, the manufacturing method of the cover of the present invention includes a step of thickly printing desired designs, characters, etc. on the cover body using screen printing means using UV ink, and a step of printing the thickened pattern on the thickly printed part with a UV lamp. The steps of irradiating with ultraviolet rays are performed in the listed order.

〔Example〕

The example shown in the figure is an outer sheet made of thermoplastic soft synthetic resin (
A Tetron or nylon screen (2) with a film thickness of 120 microns and 60 mesh is placed on the outer surface of the outer sheet (1) using this screen (2) and UV ink (3). A desired pattern (4) is printed thickly, and then the thickly printed part (5) is irradiated with ultraviolet rays using a UV lamp (6) to assimilate the ink (3) and the above-mentioned outer cylinder note (1). ) on the inside of both ends of a pair of thermoplastic, soft composite or resin implosion rings. The entire periphery of the outer sheet (1) is welded to the periphery of the outer sheet (1). This is a complete version of the notebook power f8).

still. (9) in the figure is the workbench. αO is the squeegee and αυ is the screen frame indicator.

[For production]

The present invention is capable of obtaining a cover with a desired pattern such as a raised design or text using a so-called screen printing method, and the surface tension of UV I/K is significantly higher than that of ordinary ink. It is.

[Effects of the Invention] The present invention performs thick printing of designs, characters, etc. on the cover body using a screen printing means using UV ink, and
Since the solidification of V-I/K is carried out by irradiation with ultraviolet rays using a GV lamp, it is of course highly effective in producing detailed designs, letters, etc. very easily and at low cost. ．． In particular, the thick printing part that forms patterns such as designs and letters,
UV ink solidifies when it is maintained in a raised state due to its strong surface collapse tension (that is, by itself), so water evaporation occurs like in the case of normal ink, causing the raised shape to form. The height (depth) is not lowered, etc.
This provides excellent effects such as being able to reliably produce a cover with a sufficient number of convex designs, letters, and other patterns.
