BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing cloth on which a dye is dyed in a dot shape.

[0002]

2. Description of the Related Art Conventionally, a screen printing method, a roller printing method or the like has been used as a method for printing a cloth. In these methods, a screen, an engraving roll, etc. are prepared according to a desired printing pattern. Therefore, there is a problem in terms of both workability and economical efficiency in performing printing in a large number of small lots. Therefore, various studies have been attempted on printing using an ink jet method, for example, Japanese Patent Laid-Open Nos. 61-6347 and 2-3033.
There are patent applications such as Japanese Patent Laid-Open No. 77 and Japanese Patent Laid-Open No. 3-45774. Japanese Patent Application Laid-Open No. 61-6347 discloses that a dot-shaped dyeing is a) the average of the major axis and the minor axis is 100 to 500.
μ, b) The maximum density is 16 points / mm or less, and c) It penetrates from the front surface to the back surface of the fiber cloth so that some of the different color points are recognized as dots on the back surface of the fiber cloth. It is described that by doing so, delicate patterns can be expressed with deep colors. However, with such a dyeing method, it is not possible to obtain a deep color which exceeds that of the screen printing method.
It was not possible to express fine lines such as mm or less as a print pattern, and it was also difficult to express an accurate stripe pattern or natural blur pattern.

[0003]

DISCLOSURE OF THE INVENTION The present invention is capable of clearly producing fine lines such as 0.3 mm or less, an accurate stripe pattern, and a natural blur pattern, which cannot be obtained by the conventional method, with a deep color. It is an object to provide a dyed textile fabric.
