Embodiment 1

[0034] By using the No. 5 Meyer rod, the surface energy is 29~30erg / cm 2 A polymer resin solution bar-coats the graphic surface of an elastic mold containing PDMS as the main component. The polymer resin solution contained carbon black, an acrylic binder, a dispersant, and a surfactant, and the solvent contained propylene glycol monomethyl ether as a main component. After that, set the surface energy to 31.9erg / cm 2 A polypropylene roller was rolled on the surface of the elastic mold coated with the polymer resin solution, thereby removing the polymer resin on the surface of the relatively protruding relief part of the elastic mold by the surface of the polypropylene roller. In this way, the polymer resin is selectively filled into the intaglio of the elastic mold. After that, the elastic mold is tightly attached to the PET substrate, and then, after applying weak pressure thereto, the elastic mold is removed from the PET substrate, thus forming fine particles of polymer res...

[0036] By using the No. 5 Meyer rod, the surface energy is 29~30erg / cm 2 A polymer resin solution bar-coats the graphic surface of an elastic mold containing PDMS as the main component. After that, set the surface energy to 31.9erg / cm 2 A polypropylene plate is rolled on the surface of the elastic mold coated with a polymer resin solution, thereby removing the polymer resin on the surface of the relatively protruding relief portion of the elastic mold through the surface of the polypropylene plate. In this way, the polymer resin is selectively filled into the intaglio of the elastic mold. After that, the elastic mold is tightly attached to the glass substrate, and then, after applying weak pressure thereto, the elastic mold is removed from the glass substrate, thus forming fine particles of polymer resin on the glass substrate. graphics.

[0038] By using a No. 5 Meyer rod with a surface energy of 25.8 erg / cm 2 A polymer resin solution bar-coats the graphic surface of an elastic mold containing PDMS as the main component. After that, set the surface energy to 31erg / cm 2 The poly(butyl methacrylate) was coated on the surface of the PET plate to prepare a poly(butyl methacrylate) film, and the poly(butyl methacrylate) film was coated with the polymer resin The solution was rolled on the surface of the elastic mold, thereby removing the polymer resin on the surface of the relatively protruding relief portion of the elastic mold through the surface of the poly(butyl methacrylate) film. In this way, the polymer resin is selectively filled into the intaglio of the elastic mold.

Abstract

A method of printing fine patterns prints a fine pattern on a substrate using an elastic mold with an intaglio pattern. This method includes applying a fine pattern printing ink to a surface of a patterned elastic mold; removing the ink applied to an embossed portion of the elastic mold by closely adhering an ink removing unit having a polymer resin or an organic compound with a surface energy from <a surface energy of the ink - 2 erg / cm<2> > to <the surface energy of the ink + 8 erg / cm<2> > to the surface of the elastic mold and then detaching the ink removing unit therefrom; and closely adhering the elastic mold to a substrate to transcribe the printing ink thereto. This method allows forming a fine pattern with good quality since the ink applied to the embossed portion of the elastic mold may be effectively removed during a gravure process.

Description

technical field [0001] The present invention relates to a method of printing fine graphics, a printing system of fine graphics, and an ink removal method therefor. More particularly, the present invention relates to a method of printing fine graphics, a printing system of fine graphics, and an ink removal method therefor by efficiently removing relief applied to a printing roll during gravure printing. Ink on the part, which can form fine graphics with high quality. Background technique [0002] The gravure printing method for forming fine patterns is performed in such a manner that a pattern-forming material (hereinafter, referred to as "ink") is coated on a gravure mold, and then the ink existing in the relief portion is removed using a knife such as a doctor blade. residual material on the substrate, and then print the graphics onto the substrate. [0003] A conventional gravure mold used in the gravure printing method is a hard mold made of a steel material or the like...
