摘要： The invention pertains to a printing form precursor, and particularly a printing form precursor that can form printing forms, or printing plates, having improved properties. The printing form precursor includes a photopolymerizable composition containing an additive having a structure of Formula (I). The presence of the additive results in ease of processing and/or better cleanout and reduction in webmarkings on solid areas of the printing form.

摘要： Provides is a seal surface carving apparatus capable of carving a seal surface using only a single attachment irrespective of a size of a stamp. A porous impression die having a seal surface to be carved is set on a dedicated attachment, and is loaded in a seal surface carving apparatus. A fitting projection fit to a bottom portion of the impression die is formed on the attachment, and impression dice having various sizes may be set. In addition, a slit hole extending in a conveyance direction is formed in an impression die setting portion of the attachment. Impression die size determination means of the seal surface carving apparatus determines a size of the impression die by detecting a position at which the impression die blocks the slit hole.

摘要： A stamp-face platemaking device transports a medium holder inserted into a plate insertion portion to a printing unit. The medium holder holds a stamp face material at a center portion of a plate-like member, and has a cutout portion in one side end portion thereof. An optical sensor detects the top end portion of the medium holder on a sensor scanning line in the inserting direction, and the cutout start point and the cutout end point of the cutout portion. The size of the stamp face material in the inserting direction and/or the size of the stamp face material in a direction perpendicular to the inserting direction are set based on the positions of two of the detected end portions. When the cutout end point is detected, platemaking with the stamp face material is started. The cutout portion can have a wedge-like shape or a U-shape, or can change its positions and/or sizes.

摘要： An ink image is formed on the side of a gauze of a screen master by discharging ink by an ink discharge apparatus, and collected visible rays or infrared rays are irradiated onto the ink image to heat the ink. Then, a thermoplastic resin film is perforated to form a plate making image corresponding to the ink image. The minute ink drops discharged from the ink discharge apparatus are held inside minute opening portions (pixels) of fibers configuring the gauze, and are put on the thermoplastic synthetic resin film bent by gravity. Thermosensitive perforation is carried out in this state, and thus a high-definition plate making image corresponding to the image configured using the ink drops in units of pixels can be obtained.
摘要翻译： 通过由喷墨装置排出墨水，在丝网印刷机的纱布一侧形成油墨图像，并且将可收集的可见光或红外线照射到油墨图像上以加热油墨。 然后，对热塑性树脂膜进行穿孔以形成与油墨图像相对应的制版图像。 从喷墨装置排出的微小墨滴保持在构成纱布的纤维的微小开口部分（像素）内，并被放置在由重力弯曲的热塑性合成树脂膜上。 在这种状态下进行热敏穿孔，因此可以获得与以像素为单位的墨水配置的图像对应的高清晰度制版图像。

摘要： A method for digital imaging of a printing form (10) through application of energy is described, in which a burn-off area (66) is detachably fixed by supporting points (68, 84), supporting points (68, 84) being left in place on the printing form (10) through non-imaging of image spots (112) and in which the burn-off from the burn-off area (66) is detached from the printing form (10) in a cleaning step. A supporting point (68, 84) at a reference point is left in place precisely if the number of image spots (110) to be imaged in a surrounding area (18) of the reference point (12) exceeds a limit value and a boundary area (20) in the surrounding area (18) around the reference point (12) contains only image spots (110) to be imaged. The method may be used in a system for digital imaging of printing forms (10) having an energy source (86), a cleaning unit (70), a control unit (96), and an image processing unit (98) with a computing unit (100), in particular with a raster image processor (RIP) (102) in a printing unit of a printing press.

摘要： A duplex printing device comprises a duplex printing master on which a first image and a second image are perforated in series over the length of a single plate, and a simplex printing master on which a third image having an image area equivalent to the first image and the second image is perforated over the length of a single plate. The duplex printing master or simplex printing master is wrapped around an outer peripheral surface of a print drum, thereby enabling a duplex printing operation in which one of the first image and second image is printed by pressing a front side of a sheet against the duplex printing master on the print drum using pressing means which can be brought into and out of contact with the print drum, after which the other of the first image and the second image is printed by reversing and refeeding the sheet and pressing a reverse side of the sheet against the duplex printing master on the print drum using the pressing means, and a simplex printing operation in which the third image is printed by pressing one side of the sheet against the simplex printing master on the print drum. When power is supplied to the duplex printing device, during mode clearance for clearing various modes executed by the duplex printing device, and so on, a preset initial set mode can be switched between a duplex print mode for performing the duplex printing operation and a simplex print mode for performing the simplex printing operation.
