Abstract

PURPOSE:To eliminate the need for separately providing a plate making machine and a printing press by a construction wherein in a lithographic press provided with a plate cylinder, an impression cylinder, and an inking arrangement, a heat-sensitive lithographic plate which is not required to be developed is set on the plate cylinder, and image signals are recorded the plate by a printing part. CONSTITUTION:A lithographic press is provided with a plate cylinder 3, an impression cylinder 1, and an inking arrangement 6. On the plate cylinder 3, a heat-sensitive lithographic plate is set. For this plate, a developing operation independent of an image signal recording operation is not required. Image signals are transmitted from an electronic composition machine, an electronic edition and composition machine, a DTP, a personal computer, a word processor, or the like. The image signals are recorded on the heat-sensitive lithographic plate by a printing means 4 serving as an image output means for making a pressplate. In this invention, the printing part 4 is so constructed as to use a thermal head or a laser.

2. Description of the Related Art A conventional printing apparatus has only a function of printing by mounting a pre-made plate, or one having a plurality of functions, the added functions are cutting, punching, There was no function that had a plate making function before printing, such as folding. There are various reasons why the plate-making function before printing was not added in this way.For example, in the case of conventional lithographic materials, it is necessary to develop and dry the image signal after recording it on the plate material with ultraviolet rays, visible light, or heat. Met. For this reason, it is mechanically rather complicated to develop and dry the plate material on which an image is recorded after it is mounted on the plate cylinder, which is almost unrealistic.

On the other hand, it has been attempted to integrally perform printing and plate-making instead of a single device for printing and plate-making. In this, independent devices such as a printing device and a plate-making device are connected by an automatic plate mounting device. However, there were no major advantages in terms of installation area and cost.

When a thermal head is used, the plate cylinder 3 is slightly rotated by using a stepping motor. At this time, control is stopped so that the rotation distance of the plate cylinder 3 is not irregular due to the inertial force due to the weight of the plate cylinder 3. To do it. After the plate comes to the predetermined position for printing start by the rotation of the plate cylinder 3,
The thermal head or laser 4 moves to a position required for printing, and in the case of a thermal head, is fixed at that position.
The rotational speed of the plate cylinder 3 at the time of printing, that is, plate making is determined by the sensitivity of the heat sensitive planographic material used, the thermal head, the output of the laser, and the number of printing lines.
When an image is recorded on a -3 size printing plate, the image is printed within a range of several seconds to 1 minute. When printing is completed, the thermal head or laser 4 is moved away from the surface of the plate cylinder 3.
