である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for making an offset printing plate.

、また製版コストが高くなるという問題がある。In recent years, there has been a strong demand for faster printing speeds and higher quality printing, and there has been a corresponding strong demand for improvements in plate-making methods. However, on the other hand, there are also increasing demands for improvements in the working environment.For example, in rotary letterpress printing, which is mainly used for newspaper printing,
The transition from lead plates to resin plates caused high heat, lead damage,
Improvements from heavy work etc. were achieved. On the other hand, the No. 11 oil plate has the problem of inferior printing quality compared to the lead plate, and the plate-making cost is high.

は製版時間がかかるからである。Therefore, as a new direction, a shift to a printing method using offset lithography is currently underway. As a plate-making method for offset printing plates, the printing exposure method is currently the mainstream. That is, one film original plate was exposed in close contact with a so-called 28 plate, which had been previously treated to be hydrophilic and had been coated with a photosensitive liquid on the entire surface of a #4 aluminum plate.
This is a method of image processing. However, in this plate-making method using the printing exposure method, there are several essential steps such as alignment of the 28 plates and master film, mounting, exposure, attachment and detachment of the master film, and development processing. Although effective, it is unsuitable when large-cover, high-speed printing is required, as is typically seen in new rotary printing. In other words, in this case, the predetermined number of sheets (
For example, when printing 100,000 to 200,000 sheets, n% background dirt, self-portrait defects, etc. occur, and it is necessary to replace the printing plate.Also, multiple printing plates with the same pattern are printed on rotary rotary printing machines that are required to increase speed. You also need to set the pieces. For this reason, it is necessary to print a large number of printing plates with the same pattern, that is, duplicate plates, for newspaper printing at 11 medium to large scale companies.
This is because 60 sheets of paper must be made into a plate, and the above-mentioned non-photographic printing method takes a long time to make a plate.

方法として満足し得るものではない。There is also a problem with the cost of one plate material) dIi.Therefore, multiple copies of the same offset printing plate can be printed at a higher speed.
As a low-cost method of plate making, a method has been proposed in which ink is transferred onto a hydrophilic-treated aluminum plate using an offset printing method, and the ink is fixed to reproduce the printing plate (
Japanese Patent Publication No. 56-100005, % Publication No. 55-2168)
. However, all of these are based on the offset gJ Kiri method, and the transfer is done in two steps: first from the original plate to the blanket, and then to the printing material.
Because it is a process, the reproduced printing plate has 1 on the 7th plate.
Due to its nature, the thickness of the ink film transferred to the IIi image area becomes thicker and defects such as pinholes appear.
It is unsuitable for printing plates that require a thick film. on the other hand,
Even if the amount of ink on the original plate is increased in anticipation of the thinner film thickness, the ink remains exposed on the original plate surface or blanket surface, and the pressure during transfer may cause the image to become thicker or blur in the image area. Image quality such as resolution 9
causing a decline. In addition, the surface of the reproduction printing plate is a rough aluminum surface or a boehmite-treated surface that does not absorb ink, and offset printing methods generally use dampening water, which has an adverse effect on the hydrophilic treated surface. This is not a satisfactory plate-making method.

に印刷できることからである。? The reason why a waterless intaglio plate having an elastic body (an elastic body) was used as a master plate for direct printing is that printing must first be performed on the hydrophilized rough surface of the substrate. That is, in the case of waterless intaglio printing, no water is used, so there is no occurrence of pinholes due to emulsification of ink, etc., which is the problem with offset printing, which requires dampening water. Second, the ink transfer level can be adjusted by changing the depth of the recesses on the printing plate (specifically, by changing the thickness of the silicone rubber layer tS), and third, the lower layer of the original plate contains an elastic material. By providing the layer @, printing can be performed directly on the reproduction printing plate, improving the printing quality.Fourthly, the recesses on the plate surface play a role as ink pockets, and the elastic layer (6) etc. By maintaining a constant printing pressure, ink does not protrude from a part of the intaglio plate, and printing can be performed faithfully on the back of the original plate.

First, the transfer ink is applied to the ink supply roller (not shown) and the ink deposit roller (not shown) to the concave part (to the WL surface).
K is supplied. Next, when the silicone rubber layer α◆ of the intaglio plate is in contact with the aluminum substrate (roller) for the reproduction printing plate, the printing pressure PK applied to the plate cylinder causes the elastic layer (6) and the photosensitive layer to (2), and the silicone rubber layer α is pressed. Then, after a period of time, the elastic layer became compressed (
