Description

The dry-transcribing method on coloring board}

The present invention relates to a dry transfer method on a paint plate material, screen printing or stencil on the outside of dry heat transfer by placing a transfer paper printed on a release paper with disperse dye ink on the surface of a metal plate material (spray, electrodeposition, powder) coated by various means. It relates to a method of coating drying the surface after the operation.

Usually, in order to beautify the design of a board such as a fire door or a tile, color patterns or photographs are expressed.

Here, the expression method is ① screen printing method to repeatedly print various patterns or pictures on the board according to the colors, ② attach a release paper printed with color patterns or pictures, and apply heat to glue the printed layer of the release paper on the board. 3) How to bond color-printed vinyl paper to the plate, ④ Form a coating layer (printing layer) on the plate and heat the color pattern or photograph on the transfer paper on which the sublimable dye is transferred. Dry transfer methods such as printing to the coating layer is used.

In the above method, ① means for screen-printing on the plate has the disadvantage of low economical efficiency due to the inconvenience of having a screen plate according to the color and having to go through the printing process separately. ② means for transferring the color patterns or photos of the release paper onto the plate. Although it is convenient for work, the color pattern or the picture on the release paper is not transferred completely on the plate, so the defect rate is high and the surface layer is weak so that it is easily damaged when scratched by external shocks. ③ The vinyl with the color pattern or photo expressed on the plate Adhesive or heat means is bad when air enters between plate and film. In case of heat adhesion, if the temperature is not uniform, color pattern or photograph will be deformed and the surface film will be easily damaged by external impact. There is a closed end, ④ Form a coating layer (printing layer) on the plate and color patterns or photos When the transfer paper transferred to a sublimable dye is heated and pressed in a dry state, the color pattern of the transfer paper or the dye of the transfer body of the photograph penetrates into the cured coating layer, and the printing is performed. Although it has an easy feature, it is sensitive to the hardening state of the coating layer into which the sublimable dye is introduced into the plate, the thickness of the coating layer, the compressive force between the transfer paper, and the heating temperature, so that the defect rate is high. In particular, when the content of the curing agent is high, the coating layer becomes like scales in the printing process. If the cracking and the content of the curing agent are insufficient, the transfer paper sticks to the coating layer of the plate when the compressive force and the heating temperature are high, resulting in staining. If the compressive force and the heating temperature are low, the transfer is poor. Control the compression force, heating temperature, heating time and transfer according to season during transfer As the gun changes, a high degree of inferior transcription is required, while high professionalism and precision are required, and the pattern is printed on the plate by using dry transfer and screen printing or by tapping on a model plate with dry transfer and stencil (Acrylic) paint on a sponge. How to make the expression] such as screen printing and stencil work on the coating layer is not possible at the same time, because the coating part must be removed, it can not be parallel and monotonous waste is generated.

Therefore, the present invention is to solve the conventional closed closure, improve the process of the dry transfer method, and perform the dry transfer on the coated plate or after the screen printing or stencil operation around the dry transfer, the dry transfer layer is liquid It is an object of the present invention to provide a dry transfer method of a painted plate that can be printed on the printing layer and the screen printing layer or stencil portion of the coating layer.
