Abstract

PROBLEM TO BE SOLVED: To provide a method and equipment for printing a cover of a book by hot stamping and a foil sheet which make it unnecessary to set types, enable very simple execution of printing and, accordingly cost reduction. SOLUTION: Equipment for printing a cover of a book by hot stamping comprises a character image forming part 1 which forms image signals of characters and others to be printed, a character printing part 2 which prints the characters with toner on a material 3 to be the cover of the book on the basis of the formed image signals of the characters and others and a bonding part 6 which puts a foil sheet 5 excellent in the adhesion to the toner on the cover material whereon the characters are printed and presses these with heat. By peeling the foil sheet 5 from cover material cloth 4 taken out of the foil bonding part 6, printing by the hot stamping is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION

In bookbinding, what is sold at bookstores, that is, a book that binds a large amount of books of the same type at a time is called publication binding, and bookbinding of different kinds of books for the purpose of storage is called library binding. Good, bookbinding is roughly divided into these two types. According to the present invention, letters and the like on the cover of a book in library bookbinding for the purpose of preservation are printed by foil stamping by a method different from the conventional method. Due to the nature of library binding, characters and the like differ from one book to another, and the work of stamping and printing requires time and skilled skills.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for printing letters and the like on the cover of a book by foil stamping and an apparatus for carrying out the method.

[0002]

2. Description of the Related Art Generally, library bookbinding is performed by attaching a section to form a book block and then attaching a relatively solid cover, ie, a hard cover, to the book block. Usually, the title of the book, the name of the creator, and the like are printed in gold or other colors on the front and back surfaces of the cover.

[0003] Such a foil-press printing on a book cover is performed by incorporating a metal (chase) frame into which a metal type such as a character to be printed on the book cover is incorporated one by one, and a foil sheet of a necessary color is formed on the upper surface thereof. This is performed by a so-called foil stamping process in which a sheet of material that is to be the cover of a book is placed on top of the book, and heated and pressed by a pressurized instrument heated by a heater or the like and printed by foil stamping.
Such a conventional method of stamping the cover of a book requires a large amount of metal type printing, and when this series of operations is described in detail, it is necessary to select the type necessary for the printing, typesetting, foil stamping, release after completion, typesetting. These are labor-intensive, extremely specialized tasks, and are expensive and time-consuming. However, since there is no alternative to such a conventional method, the conventional method is still used at present.

[0004]

The present invention is a completely new method of printing a book cover by foil stamping instead of the above-mentioned conventional method, which can be made extremely simple without the need to form a type as in the conventional method. It is an object of the present invention to provide a printing method by a foil stamping method for a book and an apparatus for performing the method.

[0005]

According to the printing method of the present invention, a character to be printed is formed by an electronic image signal, and a book cover is formed based on the formed electronic image signal. Printing characters and the like by toner on the material to be formed, on the cover material on which the characters and the like are printed, a foil sheet having excellent properties of adhesion with toner is superimposed, and these are heated and pressed to adhere the foil, Next, the method comprises the steps of removing an extra foil sheet.

[0006] The printing method of the present invention by pressing a book cover foil is characterized in that a character image forming section for forming an electronic image signal of a character or the like to be printed and a book cover based on the formed electronic image signal of the character or the like. A printing unit that prints characters and the like with toner on a material that is made of, and a bonding unit that superimposes a sheet of foil excellent in adhesion with toner on the cover material on which the characters and the like are printed and heat-presses them. Be composed.

[0007]

The principle of the present invention is that the styrene / acrylic copolymer 45-50% contained in the printed toner and the iron oxide 45-
50%, polyolefin 1-3%, quaternary ammonium 1-3%, amorphous silica <1% are melted by heat, release coating layer (acrylic resin 100%) deposited on polyester film, colored coating Layer (melamine 80% rosin 20%), vapor deposition layer (aluminum purity 99.99% mixture),
This is based on bonding an adhesive layer (80% acrylic resin and 20% NC nitrified cotton mixed) by heat and pressure. Therefore, the heating temperature must be higher than the melting temperature of the toner, but if the temperature is low, the characters and the like as a foil stamp are transferred, but may be peeled off from the cover material. Therefore, it is necessary to control the temperature appropriately. The temperature is suitably 140 ° C. The pressing force is suitably set to 30 kg of the weight of the roller of the device that performs the heating and pressing.

As is apparent from the above principle, characters to be printed must be images to which toner formed by electrostatic copying is fused, but even if character images are optically formed. It may be electronic, that is, formed by a word processor or computer graphics.

The foil sheet must be excellent in adhesion to toner and not adhered to the base material of the book cover material.

[0010] The material used as the cover of the book must be one that does not melt or deform due to heating and that can print a toner image. In addition, this cover material may be peeled off with a commercially available product, and a special cover material is required. The exclusive cover material cloth must be back LS specification made by Dynic Corporation. The configuration is as follows:
Thickness = 0.21 ± 0.03 mm. Weight = 225 ± 20g
/ M. Clark stiffness = vertical 63 ± 12 horizontal 46 ± 14c
m / 100. Water content = 6.8%. Surface roughness = vertical. 25μ. Below volume low efficiency = 0.1 × 10 ¹¹ -10
Although the configuration is such as 0 × 10 ¹¹ Ωcm, the moisture content is a necessary and sufficient condition.

Hereinafter, the present invention will be described by way of embodiments with reference to the accompanying drawings.
