INSTRUCTION DESCRIPTION (1) A '---Technical Field of the Invention The present invention relates to a lithographic screen printing method for supplying I MD and injection molding, in particular to lithography and screen printing. The mutual use, not only the printing speed is fast, it is not easy to drop the paint, and can be used together with the injection molding machine to produce a variety of color change structures. [Prior Art] The general methods used for IMD printing include screen printing, baking varnishing, direct injection, and the like. Among them, the printing speed of screen printing is only about 2 丄 per hour. The printing of the trains, but not the rapid mass production, has been used less by the (IMD printing) industry; the paint is colored, and after each color, it must be dried by a lamp or oven. In addition to other colors, this method is not only time-consuming, energy-consuming, but also inconsistent with economic efficiency. Direct injection molding is currently the most popular production method for the market. It is added to the raw materials before hot pressing and injection molding. However, each time only one color can be used, the variability is not high, and the color method is produced by the method. SUMMARY OF THE INVENTION The main object of the present invention is to provide a structure in which the lithographic printing speed is fast, it is not easy to drop paint, and various color changes are produced. For the above purpose, the hair material (film) is printed. The ink of an ink brush is compatible to increase its attachment to the above-mentioned defects, avoiding the use of the missing and screen printing, and can be used not only with the injection molding machine, but also for the first lithographic printing. After the material (film) and subsequent printing degree, 'the first instant dry 1257901 five, the invention describes dry irradiation; four-color copy) print the above second lithographic printing adhesive, printed in the program, after waiting, The finished ink printing screen printing and drying equipment completes the printing single mode so that the copy is placed in the [implementation side is as follows: Please refer to the molding supply to not only the printing but also the above mentioned first flat demilitarization Printing, after the printing and printing of the upper plaque, after the second four-color ink, and then, the material with a layer of ink (film four-color copy lithography) The second instant drying of the printing ink; in the front brush, the ink is pressed into a material (film) to carry out the third to increase the printing surface; ^ design the specified color and add the thermal material (film) And the degree of ink adhesion, together with a 'plain print" [the first drying screen printing of the drying equipment, this screen printing thin family): brush finished::, can increase the follow-up plastic out η; fans After the completion of the 'after printing' process, the material r will be scanned and the material (film) will be rolled and rolled into a separate surface m Λ τ ί :: Out of shape 'and color h will be shot out After the molding is formed, it is a complete finished product.
