Description

Composite printer and its printing method {COMPLEXED PRINTER AND PRINTING METHOD USING THE SAME}

The present invention relates to a composite printer and a printing method, which is capable of pre-treatment coating for improving the adhesion of ink before printing starts, and post-treatment coating for protecting ink and preventing diffuse reflection after printing of an image, and cutting of printed output is possible. It relates to a possible multiple printer and a printing method thereof.

In general, an inkjet printer is a printing machine that prints ink through a thin nozzle and prints it on paper.

1 is a view illustrating an inkjet printer using a conventional ink, and the inkjet printer 10 may include a material 15 to be printed, that is, a paper, a fabric, or the like, in the longitudinal direction of the main frame 11. A carrier 13 having an ink head 12 that outputs colors C (Cyan: blue), M (Magenta: red), Y (Yellow: yellow), and K (black: black) in the transverse direction is printed. Printing is performed while moving in the direction perpendicular to the moving direction of (15). At this time, the carrier 13 is moved along the drive shaft 14 by a drive motor (not shown).

However, the general inkjet printer 10 outputs letters, pictures, colors, etc. by spraying ink on a paper material 15 of a white background supplied from the rear, but such a paper material is not suitable for general outdoor advertisements. .

This problem can be solved by directly outputting a material such as vinyl or PVC by using a solvent ink. However, the solvent ink generates a lot of volatile odor due to the characteristics of the solvent, resulting in poor working environment, and solvent sprayed on a vinyl or PVC material. Since the ink is not absorbed into the material, there is a problem that the output speed of the printed product is lowered by spraying a small amount of ink and drying through natural drying.

In addition, the inkjet printer 10 according to the related art may perform a printing operation when the material to be printed is a flat plate, wood, glass, stone, or metal material that is not a roll type supplied from the rear of the inkjet printer 10. There is no problem.

In addition, even when the printing operation is performed on a material with poor adhesion, there is a problem in that durability due to bleeding, light resistance, color development, water resistance, scratch, etc. of the ink is reduced.

In addition, although the conventional inkjet printer 10 is set to maintain a constant distance from the surface of the material to be printed, when the thickness of the material to be printed is irregular, the ejection surface of the ink head is in contact with the surface of the material to be printed, thereby resulting in poor printouts. There is a problem that occurs.

In addition, when the ink head is brought into contact with the surface of the material to be printed, there is a problem that a fatal damage of the ink head occurs.

In addition, if the background color of the target material to be printed is not white, that is, to express the picture on a black background, the ink is printed by spraying ink of the desired color on the material of the white background, and the rest is output by spraying black ink. By doing so, there is a problem in that unnecessary ink consumption and output time increase.

On the other hand, the inkjet printer 10 according to the prior art has a problem that it can not provide a secondary processed printed matter, such as cutting only outputs the printed matter.

This problem can be solved through the laser cutting machine of FIG.
