DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a photosensitive resin relief plate from a liquid photosensitive resin, and a production apparatus for performing the method.

[0002]

2. Description of the Related Art As a printing plate material for relief printing represented by flexographic printing such as cardboard printing or film printing, a photosensitive resin relief printing plate has been conventionally used. As the photosensitive resin relief plate, a so-called liquid type having a form that can be applied,
Alternatively, APR (trade name, manufactured by Asahi Kasei Co., Ltd.) is the most typical liquid-type photosensitive resin, which is roughly classified into two types, a so-called sheet type molded in a predetermined shape in advance. Also ALF / A
JF / AWF / ASF (all are trade names, all manufactured by Asahi Kasei) and the like are provided on the market. As a plate making process using this liquid type photosensitive resin, a negative film on which an image has already been formed by a film production system such as an image setter is set on a glass plate of an exposure apparatus,
Cover the top with a transparent cover film, apply a photosensitive resin on the cover film to a certain thickness, further laminate a base film on it, and then irradiate ultraviolet light from below the glass plate to form a negative film. Is transferred to the photosensitive resin layer to form a relief image. Next, the uncured resin is removed with a rubber spatula, or blown off with an air knife or the like, and the remaining uncured resin is completely washed off with a cleaning liquid, and subjected to necessary post-processing such as drying and post-exposure, and then subjected to printing. Resulting in a photosensitive resin relief printing plate.

[0003] With the rapid spread of computers in recent years, the improvement of their performance, and the progress of networking represented by the Internet, in the relief printing field,
In the case of making a plate from a sheet-type photosensitive resin, an apparatus and a method for selectively irradiating a photosensitive material with a laser beam based on an image recording signal to form an image have been developed. For example, in Japanese Patent Application Laid-Open No. 8-300600, an infrared photosensitive layer for shielding ultraviolet rays is provided on a photosensitive resin sheet, and the infrared photosensitive layer is burned off with an infrared laser by an external drum type laser drawing apparatus to form an image. Flexo-CTP, which is formed and then exposed to ultraviolet light via an infrared-sensitive layer by a conventional exposure apparatus, is rapidly spreading. Therefore, even when using a liquid type photosensitive resin in which an infrared photosensitive layer cannot be directly provided, a system capable of making a photosensitive resin relief plate directly from digital image data without passing through a negative film in the middle of such a long-awaited expectation. Have been.

In the case of using a plurality of optical switch arrays arranged along the length direction of 0, two adjacent rows of optical switch arrays are staggered with respect to each other because there is a possibility that a gap may be formed at a connection point of each array. It is preferable to arrange them.

2, the RIP server 80 receives image data imposed and edited by another computer via a network such as Ethernet, converts it into a digital image recording signal, and transmits it to the digital exposure head 30. Each of the optical cells selectively irradiates the photosensitive resin 200 based on the digital image recording signal.

(F) In FIG. 2, the drive mechanism 40 is supported by guide mechanisms 41 and 42 for traveling, and horizontally traverses the exposure head 30 over the applied photosensitive resin 200. The drive mechanism 40 is further connected to a drive motor and connected to the controller 7.
The digital exposure head 30 is moved at a predetermined speed along the guide mechanisms 41 and 42 based on the control signal from 0. (G) In FIG. 7, in the cleaning device 60, the uncured resin collecting device 50 is configured to remove the uncured resin adhered to the photocured photosensitive resin (hereinafter referred to as a photosensitive resin plate) integrated with the support 100. The cured resin is removed and collected by moving the hot air knife 52. After this, the uncured resin remaining on the photosensitive resin plate is
It is eluted with the cleaning liquid 63 ejected from the cleaning nozzle 62. It has a mechanism. Further, in the present apparatus, in addition to the above blocks (A) to (G), the following mechanisms can be added as necessary.

In FIG. 1, when the entire surface of the photosensitive resin 200 applied on the support 100 is to be uniformly excited and exposed to the active light, the carriage mechanism 4 keeps the active light source 10 inside as shown in FIG. The photosensitive resin 200 is moved and exposed, or the active light source 10 is used instead of the active light source 10, and exposed from above by the active light source 11 installed on the upper surface of the surface plate 2. A mechanism for exposing from below the installed active light source 12 can be provided. When four active light sources 12 are used, the surface plate 2, which is a transmission path of the active light, is made of a material through which the active light can pass, instead of a metal one.

The active light sources 11 and 12 provided on the upper and / or lower portions can also be used for exposing a hardened layer and a mask image layer to be described later. 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-winding support material supply mechanism 1 is placed on the surface plate 2 and cut into a desired size, and then the support 100 is squeezed on the support 100 with an ironing plate, a rubber roll, or the like. 100
The air interposed between the platen and the platen 2 is pushed out. The extruded air is vacuum-suctioned from the groove on the surface plate 2, discharged through a vacuum pumping pipe 90 to the outside air from a vacuum pump, and
Numeral 0 is adsorbed and fixed on the surface plate 2 in a smooth state without air pools and wrinkles.

After the support 100 is fixed by suction on the surface plate 2 by the above operation, the image data preliminarily imposed and edited by another computer is transferred to the RIP server 80 via a network or the like, and is subjected to RIP processing. The bitmap image data generated by the digital exposure head 30
, And this is a start signal for plate making start. When the start signal is input, the bucket 5
Resin 200 whose bottom is opened and housed inside
Is supplied onto the support 100, and the carriage mechanism 4 is moved at a predetermined speed in the direction shown in FIG.
A control signal is transmitted from the controller 70 so that the bottom of the bucket 5 is closed at the time when the desired area on 0 is coated with the photosensitive resin 200. The photosensitive resin 200 applied on the support 100 has a constant thickness by maintaining a constant gap between the surface plate 2 and the doctor blade at the tip of the bucket fixing plate 6.

When the photosensitive resin 200 has an anaerobic response characteristic, for example, as shown in FIG. A thin and transparent protective film 300 such as a polypropylene having a property may be laminated.
The protective film 300 is supplied to the protective film guide 14 in advance before the application of the photosensitive resin 200, and at the same time as the supply of the photosensitive resin 200 from the bucket 5, the laminating roll 13 is moved at the same speed as the moving speed of the carriage mechanism 4. And laminated on the applied photosensitive resin 200.

As an example of an alternative to the protective film 300 lamination method, as shown in FIG.
In order to apply a thin resin 400 having a characteristic insensitive to actinic rays on
The resin 400 may be supplied from the bucket 5 </ b> A together with the supply of 0, and the resin 400 may be applied onto the photosensitive resin 200 by moving the carriage mechanism 4.

When the first layer of the photosensitive resin 200 is applied, a control signal for movement is transmitted from the controller 70 to the head driving mechanism 40, and the digital exposure head 30 is moved on the applied photosensitive resin 200. Move horizontally. In synchronization with the start of the movement of the digital exposure head 30, the active light beam 500 emitted from the active light source 21 is condensed by the lens 23 and guided to the optical fiber 25, and then condensed again by the lens 31. Optical switch array 32
It is led to. Each of the plurality of optical switch cells constituting the optical switch array 32 intercepts or transmits the active light beam 500 in conjunction with a control signal converted from pre-recorded bitmap image line data into a light modulation electronic control signal. . Only the actinic ray 500 incident on the optical switch cell corresponding to the transmission control signal reaches the coated photosensitive resin 200 through the optical switch array 32, and a one-line relief image is formed on the photosensitive resin 200. You. After the first line of the photosensitive resin 200 is selectively exposed for a required time by the actinic ray 500 by such a line exposure operation, each optical switch cell returns to the light blocking state, and thereby the first line is switched. The exposure process ends.

Thereafter, the digital exposure head 30 moves to the second line position, where the line exposure process is repeated to form a second line image layer.
By repeating the line exposure process for all lines, a digital image layer is formed over the entire image forming area of the applied photosensitive resin 200. When a plurality of digital image layers are stacked after the first digital image layer is thus formed, the platen 2 is lowered by a distance corresponding to the thickness of the second layer, and the first digital image layer is lowered. A second digital image layer is laminated on the layer by repeating the application of the photosensitive resin 200 and the digital exposure cycle, and the same operation as the second layer is repeated for the third and subsequent layers to obtain sequentially. Until the plate thickness reaches the specified value.
Digital image layers are stacked.

As an example of exposing the applied photosensitive resin 200 with active light before exposure by the digital exposure head 30, for example, after the photosensitive resin 200 is applied,
There is a method in which the entire surface of the resin 200 is subjected to excitation exposure using the active light source 11 shown in FIG. By applying a weak active light energy to the photosensitive resin 200 beforehand so that the photosensitive resin 200 is not hardened by exposure by the excitation exposure, the photosensitive resin 200 is photoactivated to increase the energy level, so that the next digital exposure 30 In the exposing step, photo-curing can be performed with a small amount of active light energy.

In the case of forming a hardened layer on the entire surface, for example, after the photosensitive resin 200 is applied, the entire surface of the resin 200 is collectively exposed from the active light source 11 located above the surface plate 2. In the case of forming a mask image layer, for example, as shown in FIG. 10, after the mask film 15 is placed on the surface plate 2 made of a material that can transmit the active light, the active light can be transmitted through the mask film 15. Film support 1
After the photosensitive resin 200 is coated on the support 2 and the photosensitive resin 200 is applied on the support 2, the resin 200 is collectively exposed through the mask film 15 from the active light source 12 located below the surface plate 2. .

Further, a photosensitive resin plate having both layers may be produced by performing the formation of the mask image layer in addition to the formation of the entire hardened layer, if necessary. When all the exposure operations are completed, the vacuum suction of the grooves on the surface plate 2 is broken, the photosensitive resin plate integrated with the support 100 is peeled off from the surface plate 2 by introducing pressure, and then the uncured resin is removed. The photosensitive resin plate is fixed to the collecting plate 51 of the collecting mechanism 50, and the uncured resin is removed by the hot air knife 52. The removed uncured resin is collected and reused. Next, the photosensitive resin plate is fixed to the cleaning plate 61 of the cleaning device 60, and the remaining uncured resin is eluted with the cleaning liquid 63 ejected from the cleaning nozzle 62. After that, the final cleaning is performed through a water washing / drying / post-exposure step. Thus, a photosensitive resin relief plate to be used for printing is obtained.

[0025]

As described above, according to the present invention,
When manufacturing a photosensitive resin relief plate, since the photosensitive resin applied by a digital exposure mechanism is directly exposed from the image data, the process of producing a negative film output from a conventional image setter or the like is not required, and streamlining and Resources can be saved, and there is no need to wait for a negative film to make a plate. Further, since a general photosensitive resin having anaerobic properties can be used, a plate making system corresponding to various photosensitive resins is provided.
