Problems solved by technology

[0016]However, the above-mentioned offset printing method using the conventional technology requires the ink to have a relatively high fluidity and kiln denaturation when performing the trimming process. On the contrary, it requires Ink has an adhesive force that easily sticks to the surface of the first body, and the final printing process requires an adhesive force that prevents the ink printed on the substrate from flowing out and maintains its shape.
[0017] As a fluid, ink has both fluidity and viscosity in terms of characteristics, but usually the fluid with high fluidity has low viscosity, and the fluid with high viscosity has low fluidity. Small, so it is difficult to find a fluid that satisfies both fluidity and viscosity
[0018] Therefore, when ink with high fluidity is used, it is easy to carry out the trimming process, but there is poor adhesion of the ink on the surface of the first body and it flows, and the ink printed on the substrate cannot problems maintaining shape
[0019] On the contrary, when the ink with high viscosity is used, the ink adheres well to the surface of the first body, and the ink printed on the substrate can maintain its shape intact, but it is difficult to perform the trimming process, and the cut surface of the ink is not clean when the ink is cut with a scraper. question

Embodiment 1

[0055] The offset printing ink of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056]However, when describing the present invention, descriptions of well-known functions or structures will be omitted in order to clarify the gist of the present invention.

[0057] Fig. 2 is a schematic diagram showing the viscosity change effect of the ink for offset printing in Example 1 of the present invention. As shown in the figure, it includes: the ink 100 for offset printing in Embodiment 1 of the present invention, in which electrorheological particles 101 are diffused.

[0058] The electro-rheological phenomenon (ER: Electro-Rheological) is a phenomenon discovered by Winslow. It means that when an electric field is added to the suspension, its rheological properties, especially the viscosity and stress, increase sharply. It is a phenomenon of reversible reaction that returns to the original rheological properties in a short p...

Embodiment 2

[0070] The structure of offset printing machine of the present invention is specifically introduced as follows:

[0071] Fig. 5 shows a simplified schematic diagram of the trimming process in the offset printing process of the offset printing machine in Embodiment 2 of the present invention, and Fig. 6 shows a simplified schematic diagram of the transfer process in the offset printing process of Fig. 5, and Fig. 7 shows 5 is a schematic diagram showing a printing process in the offset printing process, and FIG. 8 is a sequence diagram sequentially showing the offset printing process in FIG. 5 .

[0072] The offset printing machine in Embodiment 2 of the present invention is composed of a first body 200 , a second body 300 , and a base plate 400 .

[0073] Among them, the first main body 200 includes one or more storage units 201 for storing the ink 100 for offset printing. The first body 200 can be composed by itself such as a conveyor belt moving along with the plane, or it ...

Abstract

The invention discloses a plasma display board of the constituted component preparing offset ink and adopting offset ink print. The invention provides an electrorheological particle to diffuse into ink and change stickiness by increasing electric field so as to properly change stickiness force based on the different procedure.

Description

technical field [0001] The present invention is an invention related to a plasma display panel equipped with offset printing ink and components printed with offset printing ink. More specifically, when manufacturing PDP electrodes and phosphors, electrorheological particles diffuse into the ink to apply an electric field. The invention relates to a plasma display panel equipped with offset printing ink and components printed using the offset ink, which can change the viscosity and thereby appropriately change the adhesive force according to each process. Background technique [0002] A plasma display panel (Plasma Display Panel, hereinafter referred to as PDP) is an imaging device equipped with elements that use the light released by the plasma generated during gas discharge to display text or graphics. [0003] This kind of plasma display panel can realize the enlargement or color effect of more than 40 inches, and has many inherent advantages that other imaging devices suc...
