Description of the invention: [Technical field of invention] The invention is an improvement of a method for printing a surface of an optical film board, and the graphic to be printed can be easily printed on the optical film board without being easily wiped off. [Prior Art] According to the prior art, a pattern printed on an optical film sheet is first rolled out of an original film of an original optical film, and then cut into a set size by a cutting device. After the cutting, the optical film plate is first aging, and after a period of time, the graphic is printed on the optical film plate, and after the printed graphic is dried, the relevant optical film plate is processed, and the printed image is processed. In the first step, the printing is performed manually. However, the manual printing cannot be performed with a very precise stamping. Among them, it is often impossible to print because of shaking or sliding, and it cannot be printed with considerable precision. When it reaches the designated location, it will be returned by the quality control department or the customer. Therefore, the automatic printing method replaces the manual printing, which not only can be accurately printed to the designated place, but also can save a lot of labor costs and working hours. However, both methods have a total of owe. After the core printing is completed, the film must be stagnant. When the film is dried, the pigment used in the printing can be further processed, and the subsequent processing steps can be carried out. Adhesion ability are poor, the relative cost of the required higher, and therefore the cost of the pigment in the process cost and time spent in printing are quite wasteful. In order to improve the method, the inventors of the present invention have made full efforts to improve the research and development, and finally have proposed a present invention which is rational in design and can effectively improve the above-mentioned deficiency. σ [Summary of the Invention] The present invention is an improvement of a method for automatically printing a pattern on an optical film surface. The main purpose of the invention is to reduce the contact angle of the optical film sheet and make the surface rough: if an acid test is used Corona method (Corona), in order to increase the effect of pigment adhesion on the optical film, so that the pigment is not easily removed, and the corona method is based on the electrostatic discharge method to improve the coating of the plastic film. Adhesion, which solves the problem of adhesion caused by printing of polypropylene or polyethylene film. In addition, the moisture generated on the surface of the film and the high solids radiation cumable ink cause an increase in surface energy. For example, both polyvinyl chloride and polyester are such films. The pretreatments generally employed for films include: combustion treatment, corona treatment, or coating operations that enhance adhesion. The corona treatment system includes: a generator, a high voltage transformer, and a treating machine. The processing machine is basically a capacitor, and the processed material is placed between the electrodes, so that The voltage is gradually increased until the purpose of corona treatment is achieved. Therefore, corona treatment can increase surface oxidation, promote chemical bond cleavage and cause more hydroxy 1 groups, carbonyl bonds and peroxidation. Hydrogen bond, then the surface of the film surface 269116 will change roughen, which will reduce the surface contamination. The plastic film is usually placed between the rollers and treated with bipolar substances, and passed through the electrodes and electrodes. The surface is separated by a few centimeters. Corona treatment decreases with time, and its response factors include: elevated temperature and humidity, in addition to reducing surface energy and improving slipperiness after painting. The additive, therefore, corona treatment needs to avoid the occurrence of blockiness and the increase of surface energy to affect the unwinding and winding. The improvement of the automatic printing method applied to the surface of the optical film board. The second objective is to wait for the two-stage aging time. The invention only needs to wait for the optical film board to mature after the automatic printing and cutting are completed. Therefore, the time for the production process can be saved. The invention is an improvement of the method for automatically printing the surface of the optical film, the steps comprising: (a) forming an original film of an optical film; (b) making the optical film The contact angle on the surface of the board is lowered; (c) the pattern is automatically printed on the optical film; (d) cut to a set size range; (e) placed for a period of time to aging the optical film; (f) The optical film of the present invention can increase the adhesion of the pigment on the surface of the optical film by lowering the contact angle of the surface, so that the pattern automatically printed on the optical film can be easily removed. The present invention will be described in detail by the following specific embodiments, with reference to the accompanying drawings, and the following description of the present invention. [Embodiment] Please refer to FIG. Place The invention is a flow chart of the steps of the invention. The invention is an improvement of the method for automatically printing the surface of the optical film board, and the steps thereof include: (a) an optical film plate 10 (for example, a polarized acupoint, see FIG. 2A) The raw material 1269116 is formed into a film of the optical film sheet 10 by rolling, and the material of the optical film sheet 10 may be tyrosine acetate fiber (CAB) or triacetate fiber (TAC); (b) the surface of the optical film sheet 10 is made. The upper contact angle is lowered, wherein the surface of the optical film sheet 10 is roughened to reduce the contact angle to increase the adhesion of the surface of the optical film sheet 10, and the optical film sheet 10 is lowered. The contact angle of the surface is such that the acid-base method and the corona method (Corona) can effectively reduce the contact angle of the surface of the optical film sheet 10; (c) automatically print the pattern on the optical film sheet 10, wherein The method of printing on the optical film sheet 10 is to automatically eject the pigment onto the optical film sheet 10. Since the pigment is mainly in the form of a liquid, the pigment may form a small water droplet due to the surface tension, so that it is easy. Causing dry conditions Therefore, the pigment is automatically printed on the treated optical film sheet 10, because the surface of the optical film sheet 10 is rough and uneven, so that the contact angle of the surface tension of the pigment is easily lowered, so that the pigment can be easily attached. On the surface of the optical film plate 10, and is not easily damaged by external environment damage; (d) cutting into a set size range, after the pigment is automatically printed on the surface of the optical film plate 10, the optical film plate can be immediately 10 performing the cutting action, cutting into a pre-designed size (e) for a period of time to aging the optical film plate 10, and after the cutting, the optical film plate 10 needs to be placed for a period of time, not only the optical film plate 10 aging, and can wait for the undried pigment which is automatically printed on the optical film sheet 10 to be dried; (f) is completed, and the processing at the rear end thereof is not the focus of the present invention (for example, after removing the optical film sheet 10 after cutting) The resulting burrs), so I won’t elaborate here.
