A book cover foil printing apparatus according to the present invention includes a character image forming unit (1) for forming an image signal of a character to be printed.
And a character printing unit (2) for printing characters by toner on a material (3) which becomes the cover of the book based on the image signal of the formed characters, and toner on the cover material (4) on which the characters are printed. And a foil bonding portion (6) for stacking the foil sheets (5) having excellent adhesiveness and heating and pressing them. The foil printing is completed by peeling off the foil sheet (5) from the cover sheet (4) taken out from the foil bonding section (6).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for printing shapes such as letters and figures made of foil on the cover of a book, and an apparatus for carrying out the method.

[0002]

2. Description of the Related Art Generally, bookbinding is performed by attaching pages to each other to form a book block, and then attaching a relatively robust cover, that is, a hard cover to the bookblock. Gold or other color titles and author names are printed on the front and back of the cover.

Printing on the cover of such a book is generally performed by assembling one metal type on a metal frame called a chase, and then forming a foil of a predetermined color such as gold foil on the combined metal type. This is performed by a so-called foil stamping process, which is performed by stacking a sheet of a material to be the cover of the book and applying heat with a heater. Such a conventional method for foil-pressing the cover of a book requires a large amount of metal type characters and requires manual and skillful manipulating and typesetting, which is a very special work and costly. However, since there is no alternative method to such a conventional method, the conventional method is still used.

[0004]

SUMMARY OF THE INVENTION The present invention is an entirely new method for printing the cover of a book, which is an alternative to the above-mentioned conventional method, and it is extremely simple and does not require any cost, as in the conventional method. It is an object of the present invention to provide a method for printing a book cover and an apparatus for carrying out the method.

[0005]

According to the present cover printing method of the present invention, an image signal of a character to be printed is formed, and a toner character is formed on a material serving as a cover of a book based on the formed image signal of the character. After printing, the cover material on which the characters are printed is overlaid with a sheet of foil having excellent adhesiveness with toner, and these are heated and pressed to adhere the foil, and then the excess foil sheet is removed. It consists of steps.

Further, the present cover printing apparatus of the present invention includes a character image forming unit for forming an image signal of a character to be printed, and a toner character on a material as a cover of the book based on the formed image signal of the character. And a foil adhering portion that superimposes a foil sheet having excellent adhesiveness with toner on the cover material on which the character is printed and heats and presses these foil adhering portions.

[0007]

The principle of the present invention is that the printed toner is melted by heat and the metal foil or pigment deposited on the polyester film is adhered by heat and pressure. Therefore, the heating temperature must be higher than the temperature at which the toner melts. However, if the heating temperature is too high, the characters may be distorted, so it is necessary to control the heating temperature to an appropriate level. About 140 ° C
Is appropriate.

As is clear from the above-mentioned principle, the character to be printed must be an image on which toner formed by electrostatic copying or the like is fused, but the character image may be formed optically. It may be formed electronically, that is, by a word processor or computer graphic.

The foil or pigment sheet must have excellent adhesiveness to the toner and not be adhered to the base material of the cover material of the book, and the commercially available product "Irotech" is marketed by Too Co., Ltd. (Trade name) is preferred.

When the pigment has a relatively light color, it is preferable that the pigment film is appropriately thickened so that the color does not become dull, or that the pigment of the base color is previously attached to the pigment layer.

The cover material may be of any type as long as it is not melted or deformed by heating and a toner image can be printed. Further, it is most preferable that the base material of the cover material is flat, and in the case of the grain surface, it is sufficient if there is some unevenness such that the toner image is clearly printed, but it is not preferable that it has severe unevenness.

The present invention will now be described by way of examples with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an apparatus for carrying out the method for foil printing on the present cover of the present invention. In FIG. 1, reference numeral 1 denotes a character image forming unit to be printed, and an image of characters to be printed is formed on a screen by operating a keyboard, and the character image formed on the screen is output as an image electric signal. can do. The image electric signal from the character image forming unit 1 is supplied to the character printing unit 2. The character printing unit 2 is composed of a laser printer, and receives the image electric signal from the character image forming unit 1 to print characters by toner on the sheet 3 of the material as the cover. Cover sheet 4 with text printed with toner
Further, the foil sheet 5 is arranged so that its printed surface is adjacent to the foil.
And is passed through the foil bonding portion 6. The foil bonding portion 6 includes two heating rollers inside. When the laminated foil sheet 5 and cover sheet 4 are passed through the foil bonding portion 6, they are heated and pressed so that the foil is bonded only to the portion where the characters are printed.
When the cover sheet and the foil sheet coming out from the foil bonding portion are peeled off, the foil is bonded only to the portion where the characters are printed, and the other portions are not bonded. In this way, the same foil characters as the conventional foil stamping are printed on the front sheet of the book.

[0014]

As described above, according to the present invention, since it is not necessary to form a type, it is possible to print foil characters very easily without requiring special skill. Therefore, the cost of printing the foil characters on the cover of the book can be significantly reduced, and the value of the utility is extremely high.
