The present invention relates to a printing apparatus, a printing stand and a printing method, in particular, a vacuum contact printing apparatus, a printing stand, and a printing method for printing a pattern on the photosensitive plate by bringing a patterned plate and a photosensitive plate into close contact with each other.

Unexamined Patent Application Publication No. 2-38282 shows a print zone of a vacuum contact printing apparatus for bringing a patterned original plate into close contact with a photosensitive plate to print the pattern on the photosensitive plate. The print stand has a print stand body and a soluble sheet mounted on the print stand main body. The upper surface of the main body of the print stand is flat and there is no step. On the other hand, a protective holding frame is provided on the outer periphery of the flexible sheet, and an opening for exposing the original plate and the photosensitive plate upward is formed in the center portion. An exhaust pipe is connected to the flexible sheet.

In the case of performing a printing process using the above-described printing stand, a photosensitive plate and a disc are stacked on the printing stand main body, and a flexible sheet is placed thereon. Next, the exhaust pipe connected to the flexible sheet is used to pressurize the space between the main body and the flexible sheet. As a result, the flexible sheet, the original plate, and the photosensitive plate adhere to the main body of the printing stand. In this state, exposure is performed by irradiating a tube from above.

In the above conventional configuration, the original sheet and the photosensitive plate are covered with the flexible sheet, but the operation of exactly matching the edge portion of the opening of the flexible sheet to the edge portion of the original plate is not easy. In addition, the flexible sheet mounted on the main body having a flat upper surface deforms irregularly under reduced pressure. This deformation adversely affects the lamination state between the original plate and the laminated plate. And since the exhaust pipe is provided on the flexible sheet side, the flexible sheet easily deforms due to the weight of the exhaust pipe, further deteriorating workability.

An object of the present invention is to reduce image distortion during printing and to improve workability.

(1) A vacuum adhesion printing apparatus according to the present invention is a device for printing a pattern on a photosensitive plate by bringing the original plate on which the pattern is formed into contact with the photosensitive plate. The device is equipped with a flash stand, an opening / closing frame, an exhaust unit and a light source. The print table is for stacking the original plate and the photosensitive plate, and the top surface is flat. The opening / closing frame has an opening for exposing the center portion upward while covering the outer circumferences of the original plate and the photosensitive plate, and has a rigid frame body and a closed space jointly with the upper surface of the print table at the outer circumferential edge of the opening at the bottom of the frame body. It has an elastic seal part for forming and can be arrange | positioned upwards to a print object. The exhaust part is provided in the flash stand, and the closed space is for reducing the pressure. The light source is disposed above the flash stand.

In addition, the print table has a ring-shaped first end that protrudes upward on the outer circumferential side of the position where the disc and the photosensitive plate are placed, and at the same time has an annular end made of an elastic body, and wherein the elastic seal portion can elastically adhere to the outer circumference of the disc. It is preferable to have a 2nd annular chamber which can stick to the said end part. The upper surface of the print table preferably has a groove for facilitating the pressure reduction between the upper surface and the photosensitive plate.

(2) A printing stand according to the present invention is a printing stand of a vacuum adhesion printing apparatus which prints a pattern on a photosensitive plate by bringing the original plate on which the pattern is formed into the photosensitive plate. The print stand has a print stand main body, an end portion, and an exhaust part. The print table main body is for stacking the original plate and the photosensitive plate, and the upper surface is folded. The said end part is provided so that it may protrude upwards on the upper surface of the main body of a printing stand at the outer peripheral side of the position where the original plate and the photosensitive plate were mounted, and are an annular elastic body. The said exhaust part is provided in the main body of a print table, and is for depressurizing the space enclosed by the said edge part.

Moreover, it is preferable that the upper surface of the said print table main body has a groove for facilitating decompression between the upper surface and the photosensitive plate.

(3) The vacuum adhesion printing method according to the present invention is a method of printing a pattern on a photosensitive plate by bringing the original plate on which the pattern is formed into contact with the photosensitive plate. This method includes a preparation process, a placing process, a seal process, an exhaust process, and an exposure process. In the preparatory process, an upper end of the printing table body on which the upper surface is folded for placing the original plate and the photosensitive plate, and an end portion of an annular elastic body installed to protrude upwards on the upper surface of the printing table main body on the outer circumferential side of the position where the original plate and the photosensitive plate are placed; A flash stand provided in the main body of the print stand and provided with an exhaust unit for depressurizing the space surrounded by the end is prepared. Next, in the mounting step, the original plate and the photosensitive plate are stacked on the print main body. In a seal process, the outer peripheral part upper surface of a disk, the edge upper surface, and the upper end surface are sealed. In the exhaust process, the space surrounded by the end is exhausted by the exhaust unit. Then, the exposure process is performed from above on the original plate and the photosensitive plate which are superimposed on the main body of the printing stand in the exposure step.

In addition, it is preferable that the said real process includes the process of sticking so that a vacuum tape may be spread between the upper surface of the outer peripheral part of the said original plate, and the said upper surface of the said edge part. Moreover, it is preferable that the said real process includes the process of mounting the flexible transparent plate which covers the upper surface of the said disk and the upper surface of the said end on the said disk and the said edge part.

(1) In the vacuum contact printing apparatus according to the present invention, an original plate and a photosensitive plate are placed on the object to be printed. Next, the opening and closing frame is disposed thereon. As a result, a closed space is formed between the open / close frame and the print stand in a state where the center portion except the outer peripheral portions of the original plate and the photosensitive plate is exposed upward from the opening of the frame body. Here, since the frame body which has high rigidity which can cover the outer peripheral part of an original board and a photosensitive plate is used, it is easy to form a closed space. Next, the closed space is decompressed by the exhaust portion. As a result, the original plate and the photosensitive plate are fixed to the object to be printed. Also in this decompression operation, since a frame body having rigidity that can cover the outer circumferential portions of the original plate and the photosensitive plate is used, deformation due to the reduced pressure is small, and as a result, accurate lamination state between the original plate and the photosensitive plate is maintained. In addition, since the original plate and the photosensitive plate are disposed along the upper surface of the flat printing table, the distortion of the original plate and the photosensitive plate is small. Next, although the exposure process is performed by the light source, the accurate lamination state of the original plate and the photosensitive plate is maintained, and the warpage of the original plate and the photosensitive plate is small, so that the image distortion during printing is small.

The first annular chamber may protrude upwards on the outer circumferential side of the position where the disc and the photosensitive plate are placed, and at the same time have an annular end made of an elastic body, and the elastic thread portion may elastically adhere to the outer circumference of the disc. In the case of having a second annular chamber capable of adhering to the end, the action becomes more remarkable. When the upper surface of the print zone has a groove for facilitating the pressure reduction between the upper surface and the photosensitive plate, the above effect becomes more remarkable.

(2) In the flash stand of the vacuum contact printing apparatus according to the present invention, an exhaust part is provided on the side of the main stand of the print stand. Therefore, the exhaust portion does not adversely affect its work when the pressure is reduced by the exhaust portion to bring the original plate and the photosensitive plate into close contact. In addition, since the end portion of the annular elastic body is formed in the main body of the printing stand, the height difference between the upper surface of the original plate and the upper end surface of the peripheral plate can be reduced while the original plate and the photosensitive plate are placed on the printing base body. This is facilitated. In addition, the deformation of the seal member at the time of reduced pressure becomes small, and it becomes easy to maintain the accurate lamination posture of the original plate and the photosensitive plate. As a result, high workability and reduction of image distortion upon printing can be achieved.

In addition, when the upper surface of the main body of the printing stand has a groove for facilitating the decompression between the upper surface and the photosensitive plate, the above effect becomes more remarkable.

(3) In the vacuum adhesion printing method according to the present invention, an end portion of an elastic body having a conversion in the upward direction is provided on the outer circumferential side of the position where the original plate and the photosensitive plate are placed on the printing surface main body having a flat upper surface, and the exhaust portion is a printing table. It is installed on the main body side. Therefore, the exhaust portion does not adversely affect the work when the original portion and the photosensitive plate are brought into close contact with each other by reducing the pressure by the exhaust portion. In addition, since the annular end portion is formed in the main body of the printing stand, the height difference between the upper surface of the original plate and the upper end of the surrounding plate can be reduced while the original plate and the photosensitive plate are placed on the main body of the printing stand, and the actual work becomes easy. . In addition, the deformation of the seal member at the time of reduced pressure becomes small, and it becomes easy to maintain an accurate deficit position between the original plate and the photosensitive plate. As a result, high workability and reduction of image distortion during printing are achieved.

Moreover, the said action becomes more remarkable when the said real process includes the process of sticking so that a vacuum tape may be spread between the upper surface of the outer peripheral part of the said disk, and the upper surface of the said edge part. Moreover, the said action becomes more remarkable when the said real process includes the process of mounting the flexible transparent plate which covers the upper surface of the said disk and the upper surface of the said end on the said disk and the said edge part.

The upper surface 6a of the upper surface 6 of the main body 6 has a high precision and a high rigidity, and has high rigidity and works effectively during the decompression treatment. Has a groove 6b. The end portion 7 is elastic (for example, made of rubber) and has an opening 7a in which the disc 50 and the photosensitive plate 51 can be accommodated. The height of the edge part 7 is set so that it may become substantially equal to the total thickness of the original plate 50 and the photosensitive plate 51 superimposed on the upper surface 6a.

Exhaust pipe 8 formed in main body 6 in the space between opening 7a and original plate 50 and photosensitive plate 51 with original plate 50 and photosensitive plate 51 mounted on top surface 6a. This opening is open. The other end of the exhaust pipe 8 is connected to the valve 9, and the exhaust pipe 8 is connected to the air or the pressure reducing pump 10 through the valve 9 so as to be able to communicate.

As shown in FIG. 3, the groove 6b is formed in a lattice shape, and the upper end of the exhaust pipe 8 is opened at each corner thereof. 2 and 3 are highlighted in the thickness direction for ease of understanding.

The opening / closing frame 3 is usually a quadrangular frame body, and has a quadrangular frame body 3b having an opening 3a at the center thereof. The inner end of the opening / closing frame 3 is freely connected to the main body 6 via the hinge 11 as shown in FIG. In addition, a pair of gas springs 12 are provided between the opening / closing frame 3 and the print table 2, whereby the opening / closing frame 3 is gently applied upwards.

Two sets of seal portions 13 and 14 are provided on the lower surface of the opening / closing frame 3 so as to surround the opening 3a. The annular chamber portion 13 on the inner circumference side elastically contacts the outer peripheral portion of the upper surface of the disc 50 when the opening / closing frame 3 is closed, as indicated by the double-dotted line in FIG. The annular chamber portion 14 on the outer circumferential side is elastically in contact with the upper surface of the end portion 7 when the opening and closing frame 3 is closed. As a result, the space enclosed by both annular chambers 13 and 14, the edge part 7, the main body 6, the disc 50, and the opening / closing frame 3 becomes airtight with respect to the exterior.

Next, the printing method as an embodiment of the present invention will be described using the above-described embodiment.

First, the photosensitive plate 51 is put on the main body 6 in the state which opened the opening-closing frame 3, and the original plate 50 is piled up on it. Next, the opening / closing frame 3 is rotated from the solid line state of FIG. 2 to the double-dotted line state, and the annular chamber portions 13 and 14 provided on the lower surface of the opening / closing frame 3 are respectively the upper surface and the end portion 7 of the disc 50. Press the upper surface of the to contact. Next, the pressure reducing pump 10 is operated, and the exhaust pipe 8 is connected to the pressure reducing pump 10 side by the valve 9 so as to pass through it. As a result, the sealed space in the opening 7a of the end portion 7 is reduced in pressure. At this time, since the groove 6b is formed in the upper surface 6a of the main body 6, a rapid decompression operation is performed.

When a sufficient pressure reduction state is obtained, the original plate 50 and the photosensitive plate 50 are brought into close contact with the upper surface 6a of the main body 6. In this state, the light source 4 is turned on and the master plate 500 and the photosensitive plate 51 are exposed through the opening 3a of the open / close frame 3.

When the exposure process is completed, the valve 9 is switched to the atmospheric side and the pressure reducing pump 10 is stopped. As a result, the inside of the sealed space surrounded by the opening 7a of the end 7 returns to atmospheric pressure. Then, the operator makes the opening-closing frame 3 into the state of a solid line in the state of the dashed-dotted line of FIG. The gas spring 12 serves to reduce the force when the operator opens the open and close frame 3. In this state, the worker takes out the original plate 50 and the photosensitive plate 51 on the upper surface 6a of the main body 6.

In this case, the annular chamber portions 13 and 14 provided on the lower surface of the rigid opening / closing frame 3 adhere to the disc 50 and the end 7, respectively, to form a closed space. The laminated state of the photosensitive plate 51 is easily maintained. Moreover, since work is performed by raising and lowering the opening / closing frame 3 which has rigidity, workability is high. As a result, the image distortion at the time of printing becomes small and workability improves.

Moreover, what is necessary is just to comprise the opening / closing frame 3 as what has high rigidity, such as iron and stainless steel, for example.
