Further, by applying the flexographic printing method, it is possible to proceed to a continuous process according to the automatic feeding of the paper, and all the various documents listed above can be used and printed.

Here, the pattern of the print layer formed by the printing can be expressed by a logo, a brand, a symbol, a pattern, a letter, or the like.

Drying step ( S30 )

The drying step (S30) is a step of drying the raw paper on which the print layer is formed by passing through the printing step (S20).

At this time, in the drying step (S30), it is preferable to perform the continuous process and apply the hot air drying method to the drying efficiency of the printing layer.

Coating step ( S40 )

The coating step (S40) is a step of forming a coating layer by coating UV silicon on the printing layer of the raw paper passed through the drying step (S30).

The printing layer and the coating layer formed on one side of the base paper by reverse processing of the base paper will be arranged to face downward with respect to the horizontal plane.

Hot melt  The application step ( S70 )

The hot-melt applying step S70 is a step of forming a hot-melt adhesive layer by applying a hot-melt adhesive on the other side of the paper which has been reversed by the paper-inverting step S60.

At this time, in the hot melt application step (S70), it is preferable to use a line-shaped slot nozzle so as to cover the whole widthwise direction of the base paper so that the hot-melt adhesive can be line-coated.

In this way, the application amount of the hot melt adhesive is automatically adjusted and applied in accordance with the printing drive speed in the printing step (S20), thereby making it possible to work and manufacture a label sticker that does not have a release paper meeting the requirements of the consumer, Adhesion by hot melt adhesive can be controlled by adjusting.

Here, the hot-melt pressure-sensitive adhesive does not require a solvent, unlike the UV and water-based pressure-sensitive adhesives, and can improve the working environment as compared with the prior art.

Raw winding step ( S80 )

The raw paper reeling step S80 is a step for winding the raw paper passed through the hot-melt applying step S70.

At this time, it is preferable that a roll-type winding system having a rotational force is applied to the raw paper winding step S80 so that the paper can be automatically wound.

That is, the manufacturing process can be processed as a continuous process by applying a roll-to-roll method by matching with the raw paper feeding step S10.

2, between the hot-melt application step (S70) and the paper-wrapping step (S80), a label sticker without a release paper, which is produced by applying a hot-melt adhesive agent, A step S75 of performing a Thompson operation may be added and a step S90 of performing a slitting operation in a desired size by a customer in a post-process may be performed.
