Disclosed are a threshold value data setting device, method, and program and an image forming system capable of, even if the number of types of printing devices and printing materials is enormous, simply and easily determining threshold value data suitable for any combination thereof. A change in dot shape occurring in an image forming process from the creation of a binary image signal 46 to the formation of an image is acquired as response characteristics data 112 in a spatial frequency domain. The response characteristics data 112 is applied to create a simulated image signal in which the change in dot shape is reproduced in a simulated manner. Threshold value data 44 to be set is determined from among threshold value candidates by a comparison and/or evaluation based on quantitative values calculated by executing predetermined evaluation processing for the simulated image signal.

摘要:
The present invention relates to a printing technology wherein an endless belt-shaped printing plate 13 is wound about a plate cylinder 18 and a guide roller 19 of a printing cylinder 16 and, by using the printing plate 13, a continuous form 1 sent between the printing plate 16 and an impression cylinder 17 is printed. The plate cylinder 18 of the printing plate 16 and the impression cylinder 17a are each composed of a solid cylinder. In the plate cylinder 18, feed pins 43 are disposed in rows at an even pitch along an outer periphery of the cylinder at both ends in the axial direction. The feed pins 43 are guided by a fixed cam ring 52 and are disposed so as to project and retract freely and project in a desired region of the plate cylinder 18, respectively with respect to the cylinder surface S. Pin feed holes 37 are provided in rows in the marginal zones 34 of the endless belt-shaped printing plate 13. The endless belt-shaped printing plate 13 is formed endless by abutting and joining both ends of an elongated resinous relief printing plate so that both ends are engaged with each other and bonded with an adhesive tape from the printing surface side. The pin feed holes 37 of the endless belt-shaped printing plate 13 are engaged with the feed pins 43 of the plate cylinder 18, whereby the plate feed is guided. According to the present invention, it is possible to provide a printing apparatus and a printing method that allow clear and beautiful printing with sufficient accuracy and no printing unevenness, even if relief printing is performed on a continuous business form by using such an endless belt-shaped printing plate 13 formed from an elongated resinous relief printing plate, thus allowing photographic printing capable of microscopic characters and screen lines of 175 or more line and up to 300 lines; and also a method of attaching a belt-shaped printing plate.

A printing method includes a step of dividing the to-be-printed surface 10 of a to-be-printed object 100 into a plurality of small to-be-printed surfaces 1a, 1b, ... (a, b, ... will be omitted below) and dividing a picture 20 to be printed on the to-be-printed surface 10 into small pictures 2 to be printed on the small to-be-printed surfaces 1, a step of a creating small developed picture 3 by developing each of the small pictures 2 into a plane, a step of putting ink on small printing original plate 30 corresponding to the small to-be-printed surface 1 according to the small developed picture 2, a step of a pressing small printing blanket 40 corresponding to each of the small to-be-printed surfaces 1 against the corresponding small printing original plate 30 and transferring the ink, and a step of printing the picture 20 on the to-be-printed surface 1 by pressing the small printing blanket 30 grasped by the arm of a multi-axis robot against the small to-be-printed surface 1 to print the small picture 2.
摘要:
The letterpress printing machine comprises an impression cylinder (8), at least one inking device (11, 12, 13) with an inking train comprising inking rollers (25, 26, 28) and at least one letterpress forme cylinder (14, 15, 16) inked by said at least one inking device (11, 12, 13). Said at least one letterpress forme cylinder (14, 15, 16) is driven by first drive means (30), whereas said at least one inking device (11, 12, 13) is driven by second drive means (31, 32, 33), said second drive means (31, 32, 33) being mechanically independent from said first drive means (30). A control unit is coupled to the second drive means (31, 32, 33) to adjust a circumferential speed of the inking rollers (25, 26, 28) with respect to a circumferential speed of the letterpress forme cylinder (14, 15, 16) so as to adjust deposition of ink by the inking device (11, 12, 13) on the letterpress forme cylinder (14, 15, 16). At least one of letterpress forme (14, 15, 16) cylinder is preferably a numbering cylinder for numbering printed sheets or webs.
