Abstract

PURPOSE:To simply reproduce the color original picture on cloth and to rapidly dye the cloth by subjecting the color original picture to color separation and spraying photosensitized ultraviolet reactive dye to the cloth before irradiating the cloth with ultraviolet rays. CONSTITUTION:The electric signal subjected to color separation by a color scanner 1 is inputted to a computer 3 and, when the color original picture is projected on a CRT display tube 4, the hue of the projected image is corrected by the operation of an operation panel 5. Thereafter, a color printer 6 sprays a four-primary-color photosynthesized ultraviolet reactive dye to cloth on the basis of the output signal from the computer 3 according to a jet system. Thereafter, the cloth is irradiated with the ultraviolet rays emitted from an ultraviolet ray generator 7 to form a color image.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for enlarging printing on natural fibers, fabrics such as leather, etc. based on color originals such as color photographs or paintings.

Conventional technology Conventionally, in order to print a color original image on cloth, the original color image is separated into colors using a color scanner, etc., printed using silk screen printing, then the dye is fixed using a fixing agent, and then washed with water. is generally known.

Problems to be Solved by the Invention However, this conventional method requires the steps of fixing the color and washing with water, which is very troublesome and also has the problem that it cannot be easily printed on fabric.

The present invention has been made in view of the above-mentioned problems, and it is possible to copy original color images such as photographs onto fabrics such as handkerchiefs, T-shirts, or wall hangings using a simple method, and to dye the fabrics quickly. The purpose is to provide a color printing method.

Means for Solving the Problems According to the present invention, the above problems are solved by color-separating a color original image using a color scanner (1), inputting the color separation signals to a computer (3), and transmitting the color separation signals from the computer (3). This problem is solved by providing a color printing method for fabric, characterized in that a color printer (6) sprays a photosynthetic ultraviolet-reactive dye onto the fabric in response to a signal, and then irradiates the fabric with ultraviolet rays.

Function: Fabrics and the like sprayed with photosynthetic ultraviolet-reactive dyes by the color printer (6) develop color when exposed to ultraviolet rays, and the dyes are immediately fixed.

EXAMPLES The present invention will be specifically described below based on examples shown in the drawings.

FIG. 1 is a block diagram showing an embodiment for carrying out the method of the present invention, in which (1) is a color scanner,
This color scanner (1) electronically separates color photographs or color originals such as paintings. The electrical signals color-separated by this color scanner (1) are stored in a storage device (2) such as a disk.

This color separated signal is input to the computer (3), the original color image is projected onto the CRT display tube (4), and the color tone of the image projected onto the CRT display tube (4) is corrected by operating the operation panel (5). do.

Thereafter, a color printer (6) prints on cloth or the like based on the output signal from the computer (3). This color printer (6) conventionally used a jet method using ink, but in the present invention, instead of ink, a four-primary-color photosynthetic ultraviolet-reactive dye is used and sprayed onto the fabric by a jet method.

The photosynthetic ultraviolet-reactive dye is a dye that reacts and develops color when exposed to ultraviolet light, and is transparent and harmless.

After the color printer (6) sprays the photosynthetic ultraviolet-reactive dye onto the fabric, the ultraviolet light emitting device (7) emits ultraviolet light onto the fabric to develop a color image. As mentioned above, this photosynthetic ultraviolet-reactive dye develops color when exposed to ultraviolet rays, and even if the fabric is colored, there is no need to fix the color with a fixing agent, and washing with water is also not necessary. It is something that will take root immediately.

Effects of the Invention As described above, according to the present invention, a color printer sprays ultraviolet coloring dye onto fabric, etc., and irradiates it with ultraviolet rays, so that an original color image can be printed on fabric, etc. in a simple manner. It can also fix color like traditional,
It has the advantage that it does not require washing with water, the dye fixes immediately, and dyeing is quick. Therefore, there is an application in that the photograph taken by oneself can be easily printed on a plain T-shirt, handkerchief, or wall hanging.
