2. Description of the Related Art In recent years, photocurable resins have been generally used as relief printing materials for printing on paper containers, cardboards, paper bags, and the like.
The plate material used in these fields is
The thickness of the plate is required to be as thick as 3 to 9 mm, and the relief of the printing plate is also required to have a large engraving depth. In addition, from the viewpoint of workability when handling the printing plate, there is a demand for reducing the weight of the printing plate by eliminating unnecessary portions as the printing plate. Further, the printing plate used in this field has a high plate thickness, so that the price of the plate material is high, so that the printing plate is required to have sufficient durability.

[0003] On the other hand, the insolubilization reaction of the photocurable resin proceeds from the surface irradiated with the energy rays. Therefore, if the thickness of the resin, the size of the relief image, the depth of the relief, and the like are different, if the exposure is insufficient, the lower part is exposed. Is not sufficiently performed, and the image is undercut or side edged. A plate making method using a mask as a method for solving this problem is disclosed in JP-A-52-56606. However, in this method, the reproducibility of the relief image as a printing plate is satisfactory, but the sub-relief is formed in a floating island shape on the support, so that the printing ink or plate detergent attack on the interface between the adhesive and the resin on the support. There is a problem that the interface is apt to peel off due to printing stress when receiving.

[0005] However, this masking film is functional, but on the other hand, it has a complicated structure, so the cost is high, and the semi-blocking property is also fixed. This is disadvantageous because it is necessary to prepare a masking film having a semi-blocking characteristic according to the resin to be formed.

FIG. 1 shows the structure of a printing plate obtained by the plate making method of the present invention. This printing plate can be obtained through the steps shown in FIGS. As an example, a method of manufacturing a printing plate for printing the mark “AB” on the liquid photosensitive resin plate on a cardboard sheet, which is disposed on a carrier sheet for printing shown in FIG. 5, will be described.

[0010] First, a negative film having the mark "AB" is placed on a light table with a peelable portion 82 of a commercially available masking film (trade name: Green Top / Bokusui Co., Ltd.) facing up. A cut is made on the surface of the masking film about 6 mm larger than the outer peripheral portion of the image “AB” of the negative film with a cutter, and the portion 81 corresponding to the image portion is peeled off to produce a masking film FIG. 4b.

A negative film 3 is placed on a glass plate 2 transparent to energy rays as shown in FIG.
A transparent film 5 for protection that can be peeled off from the photocurable resin 4 is put on the photocurable resin 4. A frame 6 is provided on the outer periphery of the transparent film so as to act as a weir for the photocurable resin 4, and the photocurable resin 4 is poured onto the transparent film in the frame. The adhesive side of the transparent support 7 on which the adhesive is applied is placed on the liquid surface of the photocurable resin layer 4, and the masking film 8 is placed on the transparent support 7 so as to correspond to the image portion of the negative film. .

As shown in FIG. 7, the photocurable resin layer is exposed by irradiating energy rays 51 and 52 such as an ultraviolet lamp from outside the masking film 8 and the transparent glass plate 2. The exposed portion starts to cure corresponding to the respective patterns 31 and 81 of the masking film 8 and the negative film 3, but the unexposed portion remains liquid and the resin cured portion on the negative film 3 side has the rating "AB". Relief part 4 that matches
It becomes 1 and the cured resin portion on the masking film 8 side becomes a sub-relief portion 42 which is thickly connected to the relief portion 41 and serves as reinforcement.

Next, the masking film 8 is removed, and as shown in FIG. 8, a masking film 9 prepared in advance is placed on a transparent support 7 so as to correspond to an image portion of a negative film as in the case of FIG. The energy beam 51 is exposed for a short time. By this exposure, a cured resin layer 43 is formed around the joint between the support and the sub-relief 42, and a printing plate having the relief image of FIG. 1 more firmly joined to the support is completed.

When plate making is performed only by the exposure shown in FIG. 7 without using the exposure on the masking film 9, a structure in which the sub-relief portion is formed directly on the support as shown in FIG. Since the shape of the sub-relief tends to be side-etched, the base of the support and the sub-relief are easily subjected to stress such as washing of the plate during printing or after printing, which may cause peeling at the interface between the adhesive and the resin. There is a problem that it is easy.

On the other hand, when the entire surface of the transparent support 7 is exposed as shown in FIG. 9 without using the masking film 9 after the exposure shown in FIG. Of course, a resin cured layer is formed on the entire surface of the support around the substrate. In this case, although the same effect as in FIG. 1 can be obtained with respect to the separation between the sub-relief portion and the interface of the support adhesive, the cured portion unnecessary as a printing plate is more than that in FIG.
There is a problem that the weight of the finished printing plate cannot be reduced.

Furthermore, in the case of a liquid photocurable resin, the uncured resin can be recovered and reused, which is disadvantageous in reducing the cost of the printing plate. When exposure is performed using the masking film of the present invention, the structure of the printing plate obtained as shown in FIG. 1 can be obtained regardless of the order of the exposure.

If the energy-ray opaque portion of the masking film is practically opaque to the energy-ray permeable portion, it can be used as the masking film of the present invention. Needless to say, paper, synthetic paper, plastic film, metal foil, and the like can be used for the purpose.

Further, since two masking films are used to form the respective relief bases, even if photo-curable resins having different sensitivity characteristics must be used, the masking films are suitable for each photo-curable resin. The amount of exposure can be given by each masking film, and the convenience is excellent.

COMPARATIVE EXAMPLE 1 The same method as in Example 1 except that the exposure from the masking film and the negative film but not the exposure with the masking film was carried out in the same manner as in Example 1 was carried out. -Drying was performed. The obtained plate had the plate structure shown in FIG. 2 and peeled off from the base of the sub-relief when the sub-relief on the base film was strongly pulled.

Comparative Example 2 After exposing the masking film and the negative film in Example 1, the masking film was removed, the top cover of the plate making apparatus was closed, and the entire surface of the base film was exposed for 18 seconds. Thereafter, the uncured resin was recovered, washed, post-exposed in water and dried in the same manner as in Example 1. Although the obtained plate had the plate structure shown in FIG. 3 and did not cause separation between the sub-relief on the base film and the base film, the weight of the printing plate was heavier than that of Examples 1, 2 and Comparative Example 1. The recovered amount of the uncured resin was small, and the plate manufacturing cost (resin cost) was high.
