The digitalization (digitization) of each field is rapidly expanding and developing around the world due to the trend of Internet informationization and the rapid development of industry. In the field of textile and fashion industry, Digitalization.

In order to cope with the rapid change of fashion that is derived from the rapidly changing social trends, digital textile printing technology, which can produce a small quantity of various items rather than the existing mass production system and is free in design expression, It is a technology that meets the demands of the times, such as diversification of design, personalization of fashion and shortening of delivery, as well as social demand for solving environmental pollution, labor intensiveness and inefficiency.

In addition, by utilizing the technology, we are responding to short deadlines by minimizing processes, reducing fixed costs, creating new designs by improving various color and pattern expressions, and achieving marketing effects using advanced network and database systems.

Here, the digital textile printing is called DTP (digital textile printing) or DDP (direct digital printing). The digital textile printing is a process of designing the ideas starting from the designers' Which means 100% digitization.

Meanwhile, a comprehensive range of digital systems includes conventional image processing systems such as image processing, color simulation, and direct engraving systems for digitizing common print patterns, And the digital equipment used in the colorimetric process. However, the true meaning of digital printing means an ink jet printer system that directly prints on a fabric without using a separator.

Advantages of the digital printing method as described above include the ability to improve the product planning ability currently required in the existing printing production method, the ability to produce a sample close to the final processed product, the production of a small quantity of various items, This system is used to solve problems and problem of establishing short deadline due to process minimization, fixed cost reduction, creation of new design by improving the expression ability of various colors and patterns, marketing effect using advanced network and database system, And the positive aspects such as the reduction of wastewater treatment burden on untreated dye (printing ink) and treating agent are evaluated as efficient next generation countermeasures.

Recently, as the digital textile print and printing technology as described above rapidly develops, a design, a message, a photograph and an illustration (hereinafter referred to as "image") selected by a buyer are transferred to various materials such as clothing, bag, shoes, And the like.

In general, digital printing or printing (collectively referred to as " output ") on a release paper or transfer paper which can usually form an image, unless it is directly output to a material using special ink, After the area is removed, the release paper or transfer paper is removed after thermal bonding or heat transfer to the material.

At this time, it is practically impossible to cut delicate images such as a human hair image or a lion's fine hair image in the process of cutting the print image area and the non-image area.

Furthermore, if only the printing ink is transferred to the material, the printing image (hereinafter referred to as "image") easily falls off from the material or the durability thereof is greatly deteriorated due to no adhesive component.
