摘要： PROBLEM TO BE SOLVED: To improve a polishing accuracy of a doctor blade edge, to accurately upgrade ink filling and to shorten an operating time by providing a polishing table for polishing the edge on a flat surface in the same plane as a flat plate- like intaglio. SOLUTION: A polishing table 120 is provided on a flat surface in the same plane as an intaglio 105, and the table 120 is horizontally operated to polish in parallel direction with the edge while the edge of the blade 117 is brought into contact. That is, when the edge is worn or damaged, a doctor blade 117 is moved to the table 120, the table 120 is moved in parallel with the edge horizontally to polish the edge of the blade 117. Thus, the doctor blade edge can be easily polished without work of removing the blade, and the edge is polished horizontally in parallel while maintaining the contact state of the doctoring, and hence an excess load is not applied to the edge, and the edge can be accurately polished.

摘要： PROBLEM TO BE SOLVED: To print the pattern shape of a plate correctly and three-dimensionally by an ink layer by changing the polarity of a surface printing layer when ink is received and transferred. SOLUTION: The polarity of a surface printing layer is changed when ink is received and transferred. Namely, an intaglio 1105 is filled with ink 1107, and a blanket 1113 is rolled to receive the ink. The surface energy of the dry blanket 1113 is appropriately high so that the ink can be peeled off from the intaglio 1105. A solvent contained in the ink penetrates into the surface printing layer of the blanket, and the cohesive force of the ink increases with the decrease of the solvent. But in the blanket, the polarity changes by the absorption of the solvent to reduce the surface energy. Next, the blanket 1113 is rolled on a work 1106 to transfer the ink. Since the surface energy of the blanket 1113 is reduced, the ink is transferred quickly onto the work 1106.

摘要： PROBLEM TO BE SOLVED: To realize a highly finely patterned offset printing by removing dirt and dust, which exert a bad influence upon a blanket as much as possible by a method wherein a dustproof mechanism is equipped on the blanket, which receives an ink pattern and transfers it to a matter to be printed. SOLUTION: When a blanket cylinder enters a transferring action, as electrically conductive rubber roller 121 being under a free state so far is moved to a position contacting with the surface of a blanket 113. When printing is executed by moving a stage 102 so as to transfer an ink film on the blanket 113 to the surface of a work 106, through the contact of the surface of the blanket 113 for transferring the ink to the work 106 with the electrically conductive rubber roller 121 as it is, the static electricity and fine dirt stored on the surface of the rubber of the blanket 113 during the printing actions are handed to the electrically conductive rubber roller 121, resulting in allowing to return the blanket 113 to its electrically free state a and no static electricity effects even during repeated printing.

摘要： PROBLEM TO BE SOLVED: To always use a transfer material in a proper state for printing by a method wherein volatilization of a solvent of the transfer material occurring naturally in offset printing is made to proceed only in portions irrelevant to the printing. SOLUTION: In the equipment for offset printing having a transfer material supply means 5 for supplying a transfer material 7 to an intaglio 4, a doctoring means 6 for filling the transfer material 7 supplied to the intaglio 4 in the recess of the intaglio 4, with a surplus of the transfer material 7 removed, and a blanket 2 for receiving the transfer material 7 filled in the recess of the intaglio 4 and transferring it onto a body to be printed, the transfer material supply means 5 supplies the transfer material 7 for subsequent printing to the intaglio 4 immediately after the reception of the transfer material 7 by the blanket 2. Moreover, the doctoring means 6 conducts the removal of the surplus of the transfer material 7 and the filling thereof as to the transfer material 7 supplied to the intaglio 4 for the subsequent printing, just before the blanket 2 receives the transfer material 7 so as to conduct the subsequent printing.

摘要： PROBLEM TO BE SOLVED: To easily form an insulation film having a good insulation characteristic to a necessary shape by coating an insulative material solution in which a predetermined organic compound is dispersed or dissolved in a liquid insulative material by a printing process and baking it. SOLUTION: A viscous liquid organic compound 13 in a state of a solid or a liquid polymer at an ordinary temperature such as acetamide and acetotoluide is dispersed or dissolved in a liquid insulative material 14 capable of forming a film by baking. The organic compound 13 is evaporated from the insulation film 12 during baking by preferably using the organic compound 13 having a boiling point of 50 to 300 deg.C, lower than temperature for baking the insulation film to obtain a fine and uniform insulation film 12 without causing a pin hole and a gap. The viscous organic compound 13 is mixed to the liquid insulative material 14 to import an appropriate viscosity. Thereby, the insulation film 12 can be easily and accurately formed into a necessary pattern by coating the liquid on a substrate 11 consisting of silicate glass, etc., by an offset printing process and the substrate 11 having a large area can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a blanket for offset printing capable of suppressing a deterioration of the blanket itself to the minimum limit by simply removing a volatile component of an ink from the blanket and restarting a printing operation immediately after a treatment by shortening a stopping time of an offset printer for a recovering work. SOLUTION: The blanket comprises a blanket body having a base material part and a surface part. The base material part has a heating mechanism to be a self-temperature regulation type. A method for offset printing using the blanket comprises the steps of supplying an ink to an intaglio, scraping the excess ink by a doctor blade, then receiving a pattern on the intaglio by an ink placing surface of the blanket, transferring the received pattern to a matter to be printed, and offset printing the matter.
