An RIP server 70 that receives image data imposed and edited by another computer via a network such as Ethernet, converts the image data into a digital image recording signal, and transmits the digital image recording signal to the digital exposure head 20, a vacuum pump, an air compressor, and the like. Is provided with a vacuum suction and pressure air introduction pipe 80 connected to the air conditioner. A method for producing the photosensitive resin relief printing plate of the present invention using a production apparatus comprising such components will be described below.

The support 100 supplied from the roll-wound support source supply mechanism 1 is placed on the surface plate 2 and cut into a desired size, and the support 100 is squeezed on the support 100 with an ironing plate or the like. The air interposed between the body 100 and the surface plate 2 is extruded, and the extruded air is vacuum-suctioned from the groove on the surface plate 2 and discharged from the vacuum pump to the outside air through the vacuum exhaust pipe 60, and the support 100 is It is fixed on the surface plate 2 in a smooth state without air pools and wrinkles.

The bitmap image data generated by the RIP processing is transferred to the IP server 70 and transferred to the block memory of the digital exposure head 20 to serve as a start signal for starting plate making.

When the start signal is input, the bottom of the bucket 5 is opened and the photosensitive resin liquid 200 contained therein is opened.
Is supplied onto the support 100, and the carriage mechanism 4 is moved at a predetermined speed in the illustrated direction so that the bottom of the bucket 5 is closed when a desired area on the support 100 is coated with the photosensitive resin liquid 200. Is done. The photosensitive resin liquid 200 applied on the support 100 in this manner is
The gap between the blade and the doctor blade at the tip of the bucket fixing plate 6 is kept constant, so that the thickness becomes constant.

As shown in FIG. 8, if a thin protective film is further laminated on the photosensitive resin liquid 200 together with the application of the last photosensitive resin liquid 200 as necessary, Before the coating, the protective film 300 is supplied to the protective film guide 14 in advance, and the bucket 5
With the supply of the photosensitive resin liquid 200 from above, the protective film 300 is further laminated on the photosensitive resin liquid 200 applied by the laminating roll 13 at the same speed as the movement of the carriage mechanism 4. Thus, when the first layer of the photosensitive resin liquid 200 is applied, the controller 60 that controls the manufacturing apparatus
Then, the application area of the photosensitive resin liquid 200 is divided into a two-dimensional matrix of grid blocks, and the plane coordinates of all blocks are calculated. Based on the plane coordinates, the digital exposure head 20 is moved to a predetermined block position. A control signal for moving the plane is transmitted.

The digital exposure head 20 receives the control signal and moves a two-axis (X, Y) linear motor 30.
Moves to the first block position on the photosensitive resin liquid 200 applied at 32. Thereafter, the active light 400 emitted from the active light source 21 is collected, shaped while passing through the condenser lens 22, and guided to the two-dimensional micromirror array 23. The micromirror stores the stored bitmap image data. Only the active light 400 that has been individually rotated in conjunction with the control signal converted to the active light modulated electronic control signal and incident on the micromirror tilted toward the exposure side has its optical path changed by the mirror. The light reaches the applied photosensitive resin liquid 200 via the projection lens 24. The first block image layer is formed by selectively exposing the grid pixels constituting the first block of the photosensitive resin liquid 200 with the active light 400 for a required time by the above operation. Is completed, the digital exposure head 20 transmits an exposure end control signal to the controller 60, and the controller 60 uses the control signal to send a plane movement control signal to the second block to the two axes (X, Y) of the digital exposure mechanism 20. The driving mechanism receives the control signal, moves the digital exposure head 20 to the second block position, and repeats the block exposure to form a second block image layer. By repeating this operation for all blocks, a digital image layer is formed.

When the first digital image layer is thus formed, if necessary, the surface plate 2 is lowered by a distance corresponding to the thickness of the second layer, and the photosensitive resin liquid 200 is removed. Is repeated and the digital exposure cycle is repeated to further laminate the second digital image layer. The same operation as the second layer is repeated for the third and subsequent layers, and the digital image layers are successively laminated to the desired thickness. Formed as a digital image layer.

As an example of exposing the applied photosensitive resin liquid 200 with active light, when the photosensitive resin liquid 200 is applied, the entire surface of the photosensitive resin liquid 200 is excited and exposed by the active light source 11 on the upper side. . The excitation exposure is performed by applying a weak active light energy to the photosensitive resin liquid 200 in advance so that the photosensitive resin liquid 200 is not photo-cured to photo-activate the photosensitive resin liquid 200 and raise the energy level, so that the next digital exposure can be performed. In the process, it is an auxiliary exposure that plays a role of photo-curing with a small amount of active light energy. Further, as an example of forming the entire surface cured layer, when the photosensitive resin liquid 200 is applied, the photosensitive resin liquid 200 is applied from the upper active light source 11.
The entire surface is exposed.

One example of forming a mask image layer is as follows.
As shown in FIG. 9, the material of the surface plate 2 is limited to transparent glass or the like. After the mask film 15 is set on the surface plate 2, the transparent film support 100 Is fixed on the glass 2 and the photosensitive resin liquid 200 is applied, and the photosensitive resin liquid 200 is exposed through the mask film 15 from the lower active light source 12. In addition, if necessary, the photosensitive resin plate having both layers is manufactured by combining the above-described means for forming the entire surface cured layer and the mask image layer.

When all the exposure operations are completed, the vacuum suction of the groove on the surface plate 2 is turned off, air is introduced, and the photosensitive resin plate integrated with the support 100 is peeled off from the surface plate 2. The photosensitive resin plate is fixed to the collecting plate 41 of the cured resin collecting mechanism 40, and the uncured resin is removed by the hot air knife 42. The removed uncured resin is collected and reused. Next, the photosensitive resin plate is fixed to the cleaning plate 51 of the cleaning device 50, and the remaining uncured resin is eluted by the cleaning liquid 53 ejected from the cleaning nozzle 52, followed by washing / drying / washing.
Through the post-exposure step, a photosensitive resin relief printing plate is obtained.

[0026]

As described above, according to the present invention,
When manufacturing a photosensitive resin relief plate, the photosensitive resin liquid applied by the digital exposure mechanism is directly exposed from the image data, eliminating the need for a conventional negative film production process output from an image setter, etc., streamlining the process. In addition to saving resources, there is no need to wait for a negative film to make a plate.
