Abstract

PURPOSE:To improve the efficiency and accuracy of registering by boring punch holes for registering in a decomposition film for four colors at the same time. CONSTITUTION:The decomposition film of four colors (Y, M, C, and BK) which are decomposed by a scanner is mounted on an X-axial movable punch table 2 where a punching groove 4 is formed in an X-axial direction. Then registering is carried out with a magnifying lens 12 with a scale and a scale 14 for registering to set the film parallel, and a vacuum device for film contacting is put in operation to fix the decomposition film through vacuum holes 6. Then, positions where punch holes are bored are confirmed, the table 2 are moved to the positions, and a punching lever 10 is operated to bore the punch holes by a puncher 8 at equal intervals for four colors at the same time.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a four-color simultaneous puncher device that simultaneously punches registration punch holes for four colors in a decomposed film decomposed by a scanner during plate making. Regarding.

<Prior art and its problems> Conventionally, in plate making, when pasting the four-color separation film separated by a scanner in the post-process retouching process, first, for example, an M plate was placed on top of the Mylar film. After pasting them all together, flip them over on the photochromic film and
The retoucher used cellophane tape to attach each edition to the other Y editions, 0 editions, and BK editions, matching the image of each edition with his eyes. In this method, a person had to adjust the register one plate at a time, which was inefficient and the registration accuracy was likely to deviate.

<Problems to be Solved by the Invention> This invention solves the above-mentioned drawbacks of the manual work performed by conventional retouchers, which is inefficient and time-consuming work as humans manually register each plate one by one. This was done for the purpose of improving the problem that the register accuracy was easily deviated.

〈Means for solving problems〉 The present invention uses four colors (Y) separated by a scanner.

An X-axis movable punch table that can move the decomposition film (M, C, BK) in the horizontal direction, and an enlarged scale with scales to set the decomposition film parallel to the row of punch holes on the X-axis movable punch table. For plate making, which is equipped with a louver, a scale for registration, a vacuum hole for fixing the decomposition film on the X-axis movable table, a puncher for simultaneously punching holes in four colors in the decomposition negative film, etc. This is a four-color simultaneous puncher device.

<Example> Next, a four-color simultaneous puncher for plate making according to the present invention will be explained based on the drawings, and FIG. 1 shows the appearance of the four-color simultaneous puncher for plate making. X-axis movable punch table 2
The machine has four punching grooves 4 for the male and female punches to pass through in the X-axis direction, and by moving the X-axis movable punch table, it is possible to punch holes at any position. . The puncher 8 is fixed to the main body, and is operated by a punch lever 10, and an enlarged louver 12 with a scale and a registration scale 14 are used to make the puncher 8 parallel to the film, and the film is exposed to light. A vacuum hole 6 that performs parallel alignment by aligning the alignment mark with the registration scale 14.
This is to tightly fix the decomposition film on the X-axis movable punch table 2. After suctioning and making it parallel using a vacuum pump (not shown), the decomposition film is placed on the table so that it does not move. It plays the role of fixing.

Here, magnifying loupe 1 with scale used for parallelizing the film
2 and the registration scale 14 will be explained in detail.

Place the decomposed negative film on the X-axis movable punch table 2, visually align it roughly, and use the table movement switch 16 to move the scaled magnifying loupe 12 in the X-axis direction, and use the registration scale. 14 in the X-axis direction and set it so that it overlaps the positioning mark of the separated negative film. Here, checkout scale 14
is movable to a desired position in the X-axis direction. Here, as shown in FIG. 3, by moving the decomposition negative film 30, the peel-off film peeling portion 28 and the decomposition negative film alignment mark 32 are brought into alignment, so that accurate parallel alignment can be achieved.

That is, the registration scale 14 has a structure in which a peel-off film is adhered to the lower side of a plastic scale support 22, and the peel-off film has a negative-positive relationship with the decomposition film alignment mark 32. Similarly, since the peel-off film release layer 26 is provided, even the slightest amount of deviation can be visually detected, making alignment easier. Furthermore, the scaled magnifying looper 12 is provided with a gauge in units of 10 μm, so that the amount of deviation can be determined and correction can be made easily. The magnification of this magnifying louver is preferably about 50 to 80 times.Workability will be improved if a proofing device is attached inside the magnifying louver 12 with scales so that alignment marks can be easily aligned.

To use this puncher, first place a four-color simultaneous film that has been separated by a scanner on the X-axis movable punch table 2, and register it using the magnifying louver 12 with graduations and registration scale 14 to make it parallel. Then, the film-closing vacuum device is activated to fix the decomposition film. After confirming the position to be punched, the table is moved to that position using the movement switch 16, and the punching lever 10 is used to simultaneously punch holes in four colors at equal intervals.

Referring to FIG. 4, a description will be given of the type of film that is attached to a four-color simultaneous puncher for plate making. The decomposition film 40 usually contains a plurality of different patterns in the horizontal direction, and the decomposed images Y, MSC, BK in the vertical direction.
In this device, which has 4 versions lined up, this exploded pattern 7th version 42
, Decomposed pattern BK version 44, Decomposed pattern 0 version 46, Decomposed pattern M
This is useful for punching grooves for Y, punch holes 52 for BK, punch holes 54 for C, and punching grooves for M at the same positions from each color pattern in order to align the 4th edition of the 4th edition. .

<Effects of the Invention> Although the present invention is constructed as described above, this four-color simultaneous puncher device for plate making punches holes with the four colors in register, making it easy to paste in retouching. There is no need for a person to visually adjust the register during the work, and the pasting work can be performed using a bin bar using the eight punch holes punched by the four-color simultaneous puncher device.

In other words, for example, a pin bar is placed and fixed while a decomposition film is set on a positive inverted from a negative mount on which a printing plate has been photographed, and when all the decomposition film is set, Mylar is placed on top and pressed with a roller from the front. I'll do it. (At this time, the bottom positive and the Mylar film to be covered from above are aligned via pins.)
,M.,C.

By repeating BKJ times, you can create 4 versions of mylar paper pasted in the designated positions according to the layout. This example is an example of the main effects of using a four-color simultaneous puncher for plate making. As a result of the above, it becomes possible to perform the registration of the fourth edition efficiently and accurately.
