摘要： PROBLEM TO BE SOLVED: To solve the problem of the setting-off of printing paper in the printing method and printing equipment, in which emulsion ink is used. SOLUTION: At this printing method, ink-transferred images I are formed with emulsion ink E on a printing paper 31 and then pressed by an aqueous liquid film 3 with a carrying device 800 at an ink-transferred image fixing part so as to destruct tire emulsion of the emulsion ink in order to obtain fixed images F on the printing paper. In the carrying device 800, a carrying roller 81, between which and a press roller 82 the printing paper 31 is pinched for carrying it, is provided. On the outer peripheral. surface of the carrying roller 81, the aqueous liquid film 3 is formed. This printing equipment is composed of the above-mentioned carrying device 800.

摘要： PURPOSE:To obtain high image quality printed matter without depending on experience by providing a printing method and a printer that allows an easy evolvement of a configuration of an ink passage that provides a maximum ink discharge at the time of printing. CONSTITUTION:A porous elastic layer 32 is provided on a perforated master film 31 for stencil printing, an ink-repellent layer 34 is provided thereon, printing paper 13 is placed under the master film 31, ink is forced out of the perforations 35 of the master film 31 and transferred to the printing paper 13 by applying pressure to the porous elastic layer 32 between the printing paper 13 and the ink-repellent layer 34 while ink is supplied, and by deforming the porous elastic layer 32 by pressurization.

摘要： PURPOSE:To prevent formation of moire stripe pattern by forming a plate cylinder, which has a mimeograph master having openings following image signal wound on the outer peripheral face thereof and prints on a matter to be printed by making a printing ink pass a conducting section and a master opening from the inner peripheral face, out of a sintered body of small solid matters. CONSTITUTION:On the outer surface of a plate cylinder, faces 1-1 which are smooth being in contact with a stainless smooth face, openings 1-2 having irregular shapes, and an ink leading section having irregular distribution of openings are formed. The plate cylinder is made of a sintered body of small solid matters of thermosoftening plastic, metal, or ceramic at the time of sintering. The sintered body of the small solid matters is obtained in such a manner that the small solid matters are put into a mold of the plate cylinder after they are dried and pressed as occasion demands, heated to a temperature below the melting temperature of plastic for several minutes through several tens minutes and taken out after they are cooled. Thus, even a master consisting substantially of only resin film does not undergo mechanical damage.
