Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a plate-making puncher device for punching holes in each separation plate of a color separation film output from a scanner for registration during pasting work. .

[Conventional technology]

Conventionally, in a pasting operation for plate making, a first color separation plate, for example, an M plate, is pasted on top of a Mylar film using an adhesive tape or the like in accordance with the layout.

When all the M plates for one plate have been pasted, they are reversed on a photochrome film, and the retoucher visually adjusts the image so that it matches the image of the M plate on the photochrome film. Paste the other Y, 0, and 8 plates onto their respective Mylar films. In this way, a plate is made from four sheets of Mylar film to which separated plates of each color are pasted.

[Problem to be solved by the invention]

As described above, in the conventional pasting work, a person had to paste each plate one by one in the correct register, resulting in poor work efficiency and easy misregistration.

This invention was made to deal with the above-mentioned circumstances,
To provide a plate-making puncher device for punching holes for registration at the corresponding positions of each separation plate of a color separation film in order to perform the pasting work efficiently in a short time and with good accuracy while preventing misregistration. Its purpose is to

(Means for Solving the Problems) A puncher device for plate making according to the present invention includes a table on which a color separation film is placed via a mount, and a means for movably supporting a ψ- drill to an arbitrary position on the table. and,
After punching one hole, means are provided for moving the drill along the array of separations at intervals equal to the array period of the separations of each color in the color separation film.

[Effect]

According to the plate-making puncher device according to the present invention, first,
Position the drill at any position around the separated plate of one color,
After drilling, the drill is moved periodically along the array of separation plates at intervals equal to the array period of the separation plates of each color in the color separation film, and the drill is drilled sequentially at each stop position.
Registration punch holes can be punched at corresponding locations around each exploded plate.

〔Example〕

First, an example of a color separation film will be explained with reference to FIG. When the color separation film 10 is output from a color scanner, the color separation film 10 has Y, BK, C, and M for each color original.
4-color separated version 12y.

It is assumed that 12bk, 12c, and 12m are lined up in the vertical direction (in the axial direction when attached to the exposure cylinder of the color scanner) at a period of d. When exposing the image of each plate, a row of reference marks (register marks) i is placed on the upper side of the image as a reference for alignment.
4y, 14bk, 14c.

14 meters are also exposed at the same time. FIG. 1 shows an example in which color separation plates for three color originals are exposed onto one color separation film.

As shown in Figure 2, each color separation plate has a total of 8 perforation positions P1 to P8, two each on the top, bottom, left and right sides.
Punch holes may be punched at any two of these locations. For example, if punch holes are to be punched in Pl for the Y plate, punch holes are punched at corresponding positions for plates of other colors as well. Then, another punch hole is punched at an arbitrary position selected from P2 to P8, and punch holes are punched at positions corresponding to the Y plate in the same manner for other color plates.

As a result, two punch holes are punched at corresponding positions on the plates of all colors. Similarly, two punch holes are punched at corresponding positions on plates for other color originals. Figure 1 shows Pl.

An example of drilling at position P2 is shown. After punching holes, each disassembled plate is cut.

During pasting work, by pasting separated plates onto each Mylar film using these punch holes as a reference, all color plates can be pasted in exactly the same position.

Next, an embodiment of the plate-making puncher device according to this embodiment will be described with reference to FIGS. 3 to 5. FIG. 3 is a plan view, FIG. 4 is a front view, and FIG. 5 is a side view.

A color separation film as shown in FIG. 1 is placed on the desk 20.
A table 22 is provided.

Guide rails 24a, 2 are provided at both left and right ends of the table 22.
4b is provided. Movable members 26a, 26b are provided on the guide rails 24a, 24b. Movable member 26a,
26b is manually moved on guide rails 24a, 24b. Both ends of two balls 28.30 perpendicular to the guide rails 24a, 24b are movable members 26a, 26bl.
C can be installed. As a result, the movable member 26a.

The movement of 26b also causes the balls 28.30 to move in a direction perpendicular to the guide rails 24a, 24b.

A drill 32 is freely attached to the ball 28.

The drill 32 is automatically moved to a desired position along the ball 28 by a drive mechanism used in a known drawing machine or the like. The maximum size of the color separation film that can be placed on the table 22 is shown in broken lines in FIG. 3, and the maximum perforated range of the color separation film is shown in dashed lines in FIG.

Here, the drill 32 punches holes by rotating a hollow round blade whose perforation part is provided inside the cylinder and moving it toward the color separation film, as shown in FIG. perforate.

For this reason, the tip of the blade of the drill 32 must dig into the table 22 to some extent after punching the hole. If this is done, the table 22 will also be perforated to some extent, and the lifespan of the table 22 will become unknown.In order to prevent this, the color separation film is actually placed on the table 22 with a mount such as cardboard in between. Then, replace this mount from time to time.

The ball 3o has two magnifying scopes 34a.

34b is slidably attached. Magnifying scope 34a
, 34b are manually slid. Magnifying scope 34a, 3
4b are each provided with an index, and when placing the color separation film on the table 22, one mark in the reference mark row 14y of the color separation film, for example, the leftmost mark 14a, and one mark in the reference mark row 14m on the color separation film. Align one mark, for example the leftmost mark 14b, with these indicators. Thereby, the separated plates can be fixed horizontally with respect to the puncher WAR, and the intervals between the separated plates of each color match the predetermined intervals during exposure with the scanner. In this state, if the drill 32 is moved along the ball 28 at this predetermined interval, the drill 32
2 stops exactly at the corresponding position of all the disassembled plates.

An operation panel 36 is provided on the movable member 26a. The operation panel 36 inputs the arrangement period data d of the color separation plates to a drive mechanism used in a known drawing machine or the like. Thereby, the drill 32 can be automatically moved along the ball 28 at intervals corresponding to the arrangement of the color separation plates.

The movable member 26b is provided with a locking mechanism, and by operating the lock lever 38, the movable members 26a, 26b are locked.
movement along the guide rails 24a, 24b is prohibited.

The color separation film 10 may be fixed to the table 14 with a magnet or adhesive tape, or
The adhesive may be fixed by suction using a suction mechanism (not shown) provided in the.

Next, the operation of this embodiment will be explained. First, a color separation film is placed on the table 22, and its reference mark 14a is
, 14b is magnified by a scope 34a.

Fix it according to the mark 34b. In addition, the arrangement period data d of the separation plates of each color in the color separation film is displayed on the operation panel 3.
Enter from 6. Next, the movable member 26a
, 26b along the guide rails 24a, 24b, and the drill 32 along the ball 28,
The drill 32 is set at an arbitrary position (for example, Pl in FIG. 2) around the first color separation plate, for example, the Y plate. Then, the locking mechanism is activated to prohibit movement of the movable members 26a, 26b along the guide rails 24a, 24b. Here, the blade of the drill 32 is rotated to punch holes. After that, move the drill 32 by d, punch holes at the corresponding positions around the plate at 8, and do the same in C, M.
Drill holes at corresponding positions around the periphery of the plate.

Release the lock mechanism and move the movable member 26a.

26b to align the drill 32 with any other position around the Y plate (for example, P2 in FIG. 2), and then repeat the above operation to the corresponding position on all color plates. 2
m punch holes are punched.

Similarly, two punch holes are punched at corresponding positions on plates for other color originals.

As explained above, according to this embodiment, the drill
After drilling, the drill is moved periodically along the separation plate array at intervals equal to the array period of each color separation plate in the color separation film. Sequential drilling at the stop positions allows registration punches to be punched at precisely corresponding positions around the circumference of each disassembled plate.

Therefore, even if the size of the color separation film, the size of each separation plate, and the arrangement format change, punch holes can be punched at arbitrary positions.

Note that this invention is not limited to the embodiments described above, and can be modified in various ways. For example, although the drill is of a rotary blade type, drilling may be performed without contact using a laser or the like.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide a buncher device for plate making that punches punch holes for registration at arbitrary corresponding positions around each separation plate of a color separation film.
