Embodiment 2 An embodiment in which the method of the present invention was implemented using the plate making apparatus of Embodiment 1 will be described below. The image data preliminarily imposed and edited by another computer is transferred to the RIP server 30 via a network or the like, and the bitmap image data created by the RIP process is transferred to the line memory of the ink jet drawing apparatus 9 to start plate making. Start signal.

The carrier film 100 supplied from the material roll 1 is still stationary and stretched in a smooth state without wrinkles due to the tension of the pinch roll group 3. The adhesive rubber roll 10 for inkjet drawing descends and the carrier film 10
0 is pressed against the drawing surface plate 8 and moved while being handled. Therefore, air interposed between the carrier film 100 and the drawing surface plate 8 is extruded, and the extruded air is sucked in vacuum from a groove on the drawing surface plate 8 and discharged from the vacuum pump to the outside air through the vacuum exhaust pipe 50. Is done.

By this vacuum suction operation, the carrier film 100 is fixed on the drawing surface plate 8 in a smooth state without air pockets and wrinkles. An ink image receiving layer is provided on the carrier film 100, and the ink jet drawing device 9 converts the bit map image data into an ink discharge electric control signal according to the stored bit map image data to shield ultraviolet light from a plurality of nozzle tips. While the ink is sprayed, the drawing head traverses the carrier film 100 at a predetermined speed.

An ink image (hereinafter referred to as one band) composed of a plurality of lines corresponding to the number of nozzles is formed by one traversing of the drawing head. Thereafter, by moving the drawing head orthogonally along the carrier film 100 by a distance corresponding to the image width of one band, the drawing head moves to the next drawing position. By repeating the drawing, the entire image is formed. When the ink jet drawing is completed, the vacuum suction of the groove on the drawing surface plate 8 is turned off, and the pressure is introduced to break the vacuum suction state between the carrier film 100 and the drawing surface plate 8 to facilitate peeling.

Next, the carrier film 100 is taken up by the driving roll 4 and moved at a predetermined speed in the direction of the roll 5. When the ink image formed on the carrier film 100 approaches just before passing through the bucket 12, the bucket 12 is turned over. At least, the photosensitive resin liquid 200 is applied onto the ink image area of the carrier film 100, and the base film 300 is also moved by the laminating roll 17 at the same speed as the movement of the carrier film 100.
Further, the layers are further laminated on the top of the layer.

In this operation, the carrier film 100
Is measured in real time by the length measuring sensor 6, the falling timing of the bucket 12, the rising timing that governs the application length of the photosensitive resin liquid, and the rotation and stop timing of the laminate roll 17 are determined by the length measuring sensor 6. Controlled by command. The ink image layer formed on the carrier film 100 in this manner, the photosensitive resin liquid 200, and the base film 300 are in a state of being overlapped in three layers. At this time, the carrier film 100 is stretched in a smooth state without wrinkles by the tension of the pinch roll group 3 as in the ink drawing process.

The thickness of the photosensitive resin liquid 200 applied on the carrier film 100 is controlled by keeping the gap between the molding platen 11 and the doctor blade at the tip of the bucket 12 in the overturned state constant. Lamination of the base film 300 on the applied photosensitive resin liquid 200 is also performed while controlling the gap between the molding platen 11 and the laminating roll 17 to be constant. Thus, a photosensitive resin plate component is obtained in which the photosensitive resin liquid 200 is applied on the ink image of the carrier film 100, and the base film is further laminated thereon. The part is moved to a predetermined position in the exposure zone and then stopped.

In the exposure zone, the contact rubber roll 1 for exposure
Since the photosensitive resin plate component 9 integrated with the carrier film 100 moves downward while being pressed against the lower glass 18, the air interposed between the carrier film 100 and the lower glass 18 is pushed out. The extruded air is vacuum-suctioned from the groove on the lower glass 18 and is discharged from the vacuum pump to the outside air via the vacuum exhaust pipe 50.

By this vacuum suction operation, the carrier film 100 is fixed on the lower glass 18 in a smooth state without air pockets and wrinkles. Next, after the upper glass 21 at the upper standby position descends and is supported by the lower glass 18 via the spacer attached to the upper glass 21, the photosensitive resin plate component is passed through the groove on the lower surface of the upper glass 21. Is vacuum-sucked and vacuum-sucked to the lower surface of the upper glass 21.

As a result, the photosensitive resin plate component integrated with the carrier film 100 is held in a sandwich state by the lower glass 18 and the upper glass 21 without any gap. Thereafter, a back exposure of a predetermined exposure amount is performed from above by the back exposure irradiator 22 so that the base film side of the photosensitive resin liquid 200 is photo-cured and the base film 30 is exposed.
0, and then subjected to a predetermined amount of relief exposure from below by a relief exposure irradiator 20 and exposed to ultraviolet light transmitted through a transparent portion of the ink image drawn on the carrier film 100. Only the liquid is photocured to form a relief image.

When a negative film, which is a conventional plate making method, is used, instead of omitting the ink jet drawing step, the base of the lower glass 18 is pulled out to the near side, and the negative film is moved to a predetermined position on the lower glass 18. The negative film and the air interposed between the lower glass 18 are pushed out while the negative film is being vacuumed by operating the negative film while operating the negative film vacuum suction, and the base of the lower glass 18 is pushed into a fixed position. Manual work is added.

When the exposure is completed, the upper glass 21
By cutting off the vacuum suction of the groove and introducing pressure, the vacuum suction state between the photosensitive resin plate component and the upper glass 21 breaks, and peeling becomes easy. Next, the upper glass 21 is raised to the standby position, and the vacuum on the groove on the lower glass 18 is also cut off to introduce pressure, thereby breaking the vacuum suction state between the carrier film 100 and the lower glass 18 and peeling off. After it becomes easier, the carrier film 1 again
00 is moved by the drive roll 4 so as to be wound in the direction of the take-up roll 5, and the photosensitive resin plate with the base film integrated with the carrier film 100 is peeled off by the guide roll 2c.

The photosensitive resin plate with the base film is moved by the collection rubber roll 23, and is pressed from the base film side by the metal roll 22 descending one after another to be transferred from the photosensitive resin plate to the rubber roll 23. The removed uncured resin is scraped off by the blade 25, and the scraped uncured resin is collected and reused.

Thereafter, both ends (ears) of the base film are sandwiched by the chain conveyor 26 and sent into the washing zone, and the photosensitive resin plate remains on the photosensitive resin plate with the washing liquid ejected from the nozzle of the washing device 27. The remaining uncured resin is eluted, and thereafter, through known steps (appropriate combination of washing, draining, surface treatment, drying, and post-exposure steps), a photosensitive resin relief plate is obtained.

[0043]

According to the method and the process of the present invention, when plate making a liquid photosensitive resin relief plate by a plate making apparatus, an ink image formed on a carrier film directly from digital image data by an ink jet apparatus is exposed. Since the image can be printed as it is, the process of producing a negative film output from a conventional imagesetter or the like is not required, streamlining and resource saving can be achieved, and plate making through a negative film as in the past eliminates the inkjet drawing process. In addition, as in the conventional case, the effect that the operation can be easily achieved only by setting the negative film on the lower glass is obtained.
