摘要： PROBLEM TO BE SOLVED: To supply a recording body having no image quality deteriorating flaws on the surface to an image forming means. SOLUTION: The recording body 20 has an image (a latent image) formed by an image forming means 11, which is transferred to a recording paper 19 after being developed by a developing means 32. The flaw restoring means 40 heats the recording body 20 in order to restore flaws of the recording body. The heated recording body surface has liquid-repellency, so it is made into a lyophilic state by being heated in contact with liquid or solid by a lyophilic treatment means 30 to subsequently be sent to the image forming means 11. Thus, a recording body 20 having no flaw on the surface is forwarded to the image forming means 11 at all times, and its image quality can be rendered steady.

摘要： PROBLEM TO BE SOLVED: To prevent scumming at the time when a recorder rubs on a developing roller significantly. SOLUTION: Anti-slip means 3 are provided at the opposite ends of a recording body 2. The anti-slip means 3 is provided most simply by forming a member having high frictional coefficient at the end of a recording body supporting roller or a developing roller. The anti-slip means 3 is provided by forming a member having surface of high trictional coefficient, e.g. a member having a coarse surface, or an elastic member of rubber, for example, extremely thinly at the end of the developing roller or the recorder. Furthermore, end part of the developing roller or the recorder is roughened by sand blasting, or the like.

摘要： PROBLEM TO BE SOLVED: To prevent not only the deterioration of the durability of a thermal head but also the deterioration of resolving power, to dispense with the heating of the entire surface of a recording member in a liquid and to neglect the effect of the maintenance environment of the recording member. SOLUTION: A recording material 3 of which the sweepback contact angle is lowered upon heating in contact with a liquid and increased upon heating in the non-contact state with the liquid is applied to a substrate 2 and the coated substrate is dried to obtain a recording member (A) having a surface showing hydrophilicity and oleophilicity. When this recording member A is selectively heated by a thermal head 4 to which a current is supplied corresponding to an image signal, the recording material 3 of a heated part is increased in its sweepback contact angle to become water/oil repelling properties to form a latent image (B). The latent image formed on the recording member 1 is developed by a developing roller 5 having an ink film to obtain an image.

摘要： PURPOSE:To obtain an excellent plate wear with excellent line sharpness and resolution by providing on a support body an ink repellent layer which repels ink and contains light absorbing material which absorbs laser beam, compound having functional group reactive to isocyanate, and blocked isocyanate. CONSTITUTION:A light absorbing material which absorbs laser beam on a support body is contained in an ink repellent layer and/or intermediate layer. As a layer forming high polymer material capable of forming a layer film, a compound having functional group reactive to isocyanate and a blocked isocyanate are contained in the ink repellent layer. On the support body, a monolayer structure and a layer structure with two layers or more may be used for a printing original plate and ink repellent property is given to the surface layer. A printing plate is manufactured in such a manner that the printing original plate is exposed to laser beam, the light absorbing material absorbs the laser beam so as to heat, so that the block of the blocked isocyanate is broken, an reaction by the isocyanate occurs, and the ink repellent property is lost at that part.

摘要： Positive-working lithographic printing plate precursors comprise a substrate surface having an average oxide pore diameter of 15 to 80 nm. On this, a crosslinked hydrophilic inner layer is formed using a formulation comprising: (1) a hydrophilic polymer having recurring —CH2—CH(OH)— units, (2) a crosslinking agent for these units having at least two aldehyde groups, and (3) an acidic compound. An oleophilic outer layer formulation comprises: (a) an infrared radiation absorber, and (b) an oleophilic polymer having at least 10 mol % randomly recurring —CH2—CH(OH)— units, within an organic solvent solution, and dried to form a composite structure. The composite structure is heated so its surface exhibits less than 10% optical density change within a first rectangular area (width W1 and length L1) centered inside a second rectangular area (width W2 and length L2), where the surface is subjected to 1000 rubs according to ASTM D3181 using the organic solvent solution.

摘要： Modular printing apparatus wherein multiple central-impression presses may be linked to one another, either directly or through a perfecting assembly that reverses the facewise orientation of cut sheets. The presses each contain circuitry defining a signal and control path for the press and a plurality of electrical contacts that renders the path accessible and facilitates serial connection of the presses without disruption of the path. At least one of the presses includes a port for receiving connection to a controller, which thereby engages the signal path and, via the path, operates the presses independently or together as appropriate. The system includes a connector that is used to couple the electrical contacts of one press to those of the second press, thereby establishing a single, continuous signal and control path through both presses accessible to the controller. The system can accommodate a perfecting assembly that may be selectably engaged between the presses, and which thereby becomes a part of the system. The perfecting assembly includes circuitry defining a signal and control path for the assembly and sets of of electrical contacts capable of mating with the contacts of two presses and retaining the continuous path.

摘要： A lithographic ink and moisture control system is provided for maintaining copy quality over a wide range of operating and environmental conditions without special operator assistance. The control system, among other things, momentarily increases the moisture feed rate each time ink is added to the system to maintain a substantially constant ink/moisture balance at the master, particularly under high coverage conditions.
