Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for converting film originals photographed for printing into PS
This article relates to a device that is useful for use in registration work for accurately positioning and pasting plate materials such as plates or base films at preset positions, or registration work during book collection, etc. This invention relates to a registration device based on a completely new idea that completely overturns the conventional concept of registration.

First, we will explain the current procedure for accurately positioning and pasting each film original at a predetermined position on the surface of the printing plate with reference to the accompanying drawing (FIG. 1).

Work (1)...Depending on the size and number of individual film originals to be printed on the plate material, place around the image area of the film original at the vertical center and left and right of the image area. For the register marks printed on each center, the exact placement position is determined by determining the distance from the reference line on the plate surface and the distance between adjacent film originals, etc. Using any drawing tool, create a mount (1) on cardboard or the like with the required lines drawn on it as shown in the figure.

That is, in the figure, 4 film originals (a, bX c, d) of the same size are placed symmetrically from the center @X, Y to the left and right and one to one.
This shows the case where a mount for pasting the sheet is created, (2
) is a register mark line, and (3) is an image contour line.

Work (2)...In the register mark line (2) of the mount (1) created in the above work (11), the point where the image outline line (3) intersects the line (2) ( 2
), place a ruler on the outer side of the image area along the register mark line (2), cut it out, and open a triangular window. 4') A mount (5) having a triangular window (4) is prepared.

Work (3)...The mount (5) created in the above work (2) is superimposed on the plate material, and the triangular window (4) of the mount (5) is
), insert a writing mark X from ) A plate material (7) is created.

Work (4)...Plate material (7) with register marks (6) marked in the required places by the above work (3)
Place the film originals one by one according to the required placement position, and then place the film originals m (81) on the register marks (2) marked on the plate material (7).
9) Superimpose them individually, then use a magnifying glass to check whether the register marks t61 (91) are accurately superimposed on each other while making fine adjustments. By fixing the four corners of 8) with adhesive tape, as shown in σ)) in the same figure,
There is also a film original (8) that is precisely positioned and pasted at the required position, and a plate material (7) that can be immediately applied to a printing machine is prepared.

Thereafter, the plate material is passed through a printing machine to create a so-called printing plate in which the original image is printed on the surface of the plate material.

As is well known, in order to obtain multi-colored printed matter, it is necessary to use sekihan, gaisei,
The process involves creating four printing plates for the indigo and black versions, and printing them over and over again using the ink for each plate. Through this process, the colors, gradations, etc. of the original painting are transferred to the printed matter. Therefore, if precise registration is not performed for each plate, color misregistration will occur in the final printed matter, which will seriously impair the quality of the printed matter.

-As mentioned above, in order to obtain one multicolor print, it is necessary to create a total of four printing plates for each manuscript. In order to create a printing plate, step 1 m(2+(3)(4)) is required, and in order to create the second and subsequent printing plates, work (
It is necessary to perform operations (3) and (4) based on the mount created in step 11 (2).

By the way, in the above conventional method, it is difficult to obtain uniformity in the insertion angle of the writing instrument when scribing the register marks (6) in work (3), so There is a defect in (6) that a minute error is likely to occur in the writing position, resulting in the above-mentioned cause (color shift due to poor pasting).

Moreover, above all else, it is necessary to create a mount by the above-mentioned operation tlN2) each time a printing plate for a single printed matter is created, which is extremely complicated and inefficient, and furthermore, it is extremely complicated and inefficient. (21 in particular requires a certain degree of skill to perform the work (31 (4)), which is simply an unreasonable task.

Furthermore, intervening the work of writing register marks (6) on the plate material (7) may cause staining or damage to the surface of the plate material, and this is a work that should be avoided if possible.

On the other hand, some methods have also been adopted in which register marks are drawn directly on the plate surface using an automatic drafting device, but in this case,
Since the automatic drafting machine itself incorporates a large number of advanced equipment, it is very expensive and has major drawbacks in practical terms.Moreover, compared to the price of the automatic drafting machine, the work efficiency obtained by it is very low. There is also the problem that it cannot be expected, and furthermore, it involves the means of making notes on the surface of the printing plate (writing lines), which is by no means desirable.

The present invention fundamentally overturns the basic idea of the conventional method described above, dramatically improves the workability of registering, and provides extremely high reliability in registering accuracy. The feature of the above work (t) (2
In addition to creating the mount mentioned in ``), it is possible to completely eliminate the work of scribing register marks on the plate surface, and to create a register on the plate surface for each film manuscript as a means of registering the film manuscript and the plate material.・Simply place a thin registration wire (hereinafter referred to as "registration wire") that can be moved arbitrarily over the corresponding position of the mark, and precisely align the register mark on the film document with the registration wire. ,
The reason is that it has made it possible to achieve perfect registration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The explanation will begin with reference to the same figure.

(10) is an upper half-shaped registration wire rod with a weight 001 fixed at the intersection, and a horizontal wire rod (
IOX) has a driving pulley (12X) at one end.
The other end is wrapped around a hoisting pulley (18X) with a hoisting boot +)-(1ax), respectively,
On the other hand, the vertical wire (10”) perpendicular to the upper horizontal wire (IOX)
i), one end of which is the driving goo IJ-(,12
The other end is wound around the winding gou IJ-(13Y) equipped with a winding boot IJ-(13Y), and the other end thereof is wound around the winding boot IJ-(13Y).

(14X) is for winding and torsion pulley (18X) and drive.

The pulley (12X) and (14X) are the winding pulleys (
18X), (14Y) is the winding pulley (l BY
) and driving booley (12Y), (14Y)
is a rotating shaft formed by penetrating the five cores in each of the winding boos IJ-(taY').

In these rotating shafts, a winding pulley (15X) is attached to the rotating shaft (14X), and a winding pulley (15X) is attached to the rotating shaft (14X). ,
A lifting pulley (15X) is attached to the rotating shaft (14Y), a hoisting pulley (15Y) is attached to the rotating shaft (14Y), and a hoisting pulley (x5y) is attached to the rotating shaft (14Y) at both ends. As will be described later, the winding pulleys (13X) (13X) (18Y) (18Y) and the rotating shafts (14X) (14X') (14YX1
4Y') are constructed so that they rotate integrally, so the winding pulley and the lifting pulley (15mm x 1
5Y) (15Y') also obtains the same operation.

In addition, the drive pulleys (12X) (12Y) provided on the hoisting gear (18X) (18Y), and the rotating core (17X) of the pulse motor (16X) (16Y)
) (17Y) drive boo 'J each pivoted on the end of
-(18X)(18Y) ,! :・is a bell) (19
X) (19Y) are wrapped around each other, so the rotation of the pulse motor (16X) is as follows: Rotating core (17X) → Driving pulley (18X) → Driving pulley (12X) → Winding l
; The rotation of the pulse motor (16Y) is controlled by the rotation core (17Y) → drive pulley (18Y) → drive pulley (12Y) → winding sheath IJ- (18Y). It is now possible to convey the information to each person.

On the other hand, a hoisting pulley (taX'
) (13Y') has a coil spring (not shown) embedded in it.
The hoisting pulley (lax') is a horizontal wire rod (I
The winding pulley (18Y') constantly winds up the vertical wire (IOY).

L7'C75r is a coil spring of the winding pulley (iax'). The winding rod is wound up in the -(18X) direction against the winding action, while the pulse motor (16X) i is rotated in the opposite direction (unwinding direction) to the above, and the horizontal wire (IOX) The winding pulley is wound in one direction (i-direction) by the winding action of (13X').

7. Of course, if the pulse motor (16Y) is driven, the longitudinal wires (IOY) are constructed so that the same operation as the horizontal wires (LUX) can be obtained.

Furthermore, as is clear from Fig. 8, a pulse motor (1
6X) is fixed on a guide member (21X) that can slide freely on the guide frame (20X) while holding the guide frame (20X) arranged parallel to the rotation axis (14X)', Drive pulley (12X) and hoisting pulley (13X)
The driving pulley (12X) and the winding are inserted into the engagement groove (22X) formed along the axis of the rotating shaft (14X).
The retaining convex part (2) formed on the barb pulley (18X)
Since the rotation shaft (14X) is inserted through the shaft (14X) in such a way that the drive pulley (12X) and the hoisting boot 9-(13X) are integrated, as mentioned above, As the rotation is completed, the drive boob IJ-(12X
) and the winding goo IJ-(13X) are the rotating shaft (1
4X), and thus the winding base, designated by the reference numeral (24X), is movable back and forth along the axis of rotation (14X) and the guide frame (20X).

Incidentally, the above structure and operation are exactly the same for the winding base (24Y).

Furthermore, as is clear from Fig. 4, the winding is carried out in such a way that the retaining protrusion (28X') formed on the winding pulley (iax) fits into the retaining groove (22X) formed on the winding pulley (iax). , since the rotating shaft (14X) is inserted through it, the hoisting pulley (18X) rotates integrally with the rotating shaft (l+Q) as described above, and can also slide freely on the rotating shaft (l+Q). Moreover, the winding goo IJ-(lad) has a guide frame (2
An engaging pawl (0
A) is engaged with 1 without inhibiting the rotation of the hoisting boo IJ-(lax), so the hoisting base represented by the symbol (2 叡) is connected to the rotating shaft (14X) and the guide. The configuration and operation of the winding gate body (24t') are exactly the same. .

In addition, the winding base (24X) and (24X')
A hoisting string (27Y) is wound around a hoisting gree (15Y) fixed to both ends of the rotating shaft (14Y), and a hoisting pulley is fixed to both ends of the rotating shaft (14Y).
Since the ends of the winding string (27Y') wound around (15Y) are fixed, the winding base (24X) and (
24X) refers to the rotation of the rotating shaft (14Y) or (14Y), that is, the winding-F pulley (15Y) (18Y)
(15Y) is designed to move at the same speed as (15Y'), and the horizontal wire (IOX)
is always regulated in position at eight points of intersection between both ends and the vertical wire (IOY), and is moved in parallel to the X axis of the base (28) surface.

On the other hand, the winding bases (24Y) and (24Y) also have the same operation as above, and therefore the vertical wire rods (io
y) is also constantly regulated in position at eight points of intersection between both ends and the horizontal wire (10X), and moves parallel to the Y axis.

The horizontal wire rod (IOX) of the register wire rod (1o) is
- The force end is regulated by the pulse motor (16X), and the other end is always under the winding action by the winding sheath IJ (13X) with a built-in coil spring, so the extended state is always maintained. The same applies to vertical wire rods (IOY).

The device of the present invention having the above-mentioned configuration may be installed in a holding frame that is provided with a hinge that can be opened and closed on a base (28+) as shown in FIG. By configuring the holding frame equipped with the inventive device so that it can be horizontally spaced upward from the base surface by a desired distance, it does not interfere with the placement of plates, etc. on the base, and the plates, etc. After making it possible to operate the register wire at a position where there is no contact, and further operating the register wire at this position to the desired position,
The register wire rod is configured to be able to be lowered onto the plate material, etc., and to be able to touch the plate material, etc. with the register wire rod at this time.

In addition, if a plurality of registering wires and their driving members are arranged and configured according to this purpose, a plurality of registering wires can be arranged on one base surface, and each of them can be operated independently. It is obvious that it can be configured so as to force the user to do so.

Hereinafter, the operating method and effects of the device of the present invention will be explained in detail.

To operate the device of the present invention, for example, the N
, C. The preset counter connected to the control computer (31) is equipped with the preset counter.
By operating the required buttons on the counter C33, the pulse
Registering can be performed by operating the motors (16X) and (16Y), respectively, and moving and setting the registering wire (10)'(r) to a desired position.

First, in operation, referring to Fig. 5, lift the entire holding frame side as shown by the dotted line in the figure, and then lift the base C.
Fix the plate material in a predetermined position on the camphor tree.

Subsequently, each film original to be printed (to be pasted) is placed in a predetermined placement position and placed on the surface of the base (28) in a roughly arranged manner.

On the other hand, the user operates the numerical buttons on the 02 side of the GRISENOD COLOR/TAR 02, using the pre-calculated numerical values relating to the placement positions of each film original.

In other words, register first? For example, if the position of the register mark on the film original to be printed is set to the reference line in the If it is 25 (7) upward from X in Figure 2 and 80 cIn to the left from the reference line (Y in Figure 2), then XI → -25,0, then T: Y+-* = 80 .0 Press the number hota/,
Thereafter, in the same manner, numerical values relating to the register mark positions of the second and subsequent film originals are manually memorized.

The numerical value input in this way is the upper display window + 331
will be displayed. That is, from the same display window (331), the second film original is 25m downward with respect to the reference line 25 crn downward, 80 crn to the right with respect to reference line Y, and the fourth film original is reference line X.
It can be confirmed that the position 25 ctn upward from the reference line Y and 80 crn to the right from the reference line Y is the register mark position of each film original.

In addition, if it is below the reference line
On the other hand, in the case on the right, it is arranged that the minus button is pressed before the number buttons are pressed, in which case the stem is configured to rotate the pulse motor in the opposite direction.

Therefore, to register the first film original, first press the buttons Xl, Yj→C.

Then, the numerical value of the first film document is called up, and the apparatus of the present invention obtains the following operation.

That is, the registration wire OI is placed at the reference line position (center line XY of the base surface) by operating the reference point return button, and the register mark position of the first film original is located above the reference line. 25m to the left and 30c1n to the left, the pulse motor (16X) is connected to the horizontal wire (I
OX) 'i Required amount in the upward direction of the spring roll (vertical wire rod (IOY)
80 crn to the left).

This rotation is from rotation core (1?X) to drive pulley (18
(12 Therefore, the hoisting string (27X) also pulls the hoisting bases (24Y) and (24Y) to the left by the same amount, and thus the vertical wire (IOY) is moved 7 to the reference line m.
, 1 and are moved 30σ to the left from the ridge line while maintaining parallelism.

At the same time, the pulse motor (16Y) is running the vertical wire (1
6Y) is rotated by the required amount (to move the horizontal wire (1 (8) 25 crn upwards from the reference line) in the direction of unwinding the rotating core (1?Y) → drive pulley (
18Y) (12Y) 1 is transmitted to the hoisting pulley (18Y), and the vertical wire (IOY) is rewound by the required amount, but at the same time, the hoisting bases (24X) and (24X) are pulled by the same amount by hoisting. and thus the horizontal wire (lOX)
is moved 25 m upward from the ridge line while remaining parallel to the reference line N.

As shown in F-F, each winding base moves the position of the winding L- along the axis of rotation due to the traction action of the string while winding or unwinding the registration wire. The above operation takes place very quickly.

- According to the above, the horizontal wire rod (IOX) is placed at the corresponding position of the register mark of the film original to be registered first.
The vertical wire rods (IOY) and vertical wire rods (IOY) are set and arranged accurately, and both wire rods (HIX) are placed in the center of the film original.
A weight (11) is placed at the intersection of (IOY).

Therefore, when the holding frame Ool is lowered onto the inner surface of the base as shown by the solid line in the figure, the film original plate placed on the base (2) and the registration wire (10) are designed so that they are lightly pressed. In addition, since the center of the film original is pressed against the weight (11), the film original is held completely still.

Therefore, while making fine adjustments to the film original, align the register marks at the left and right centers around the image area of the film original with the vertical wire (IOY), and register the register marks at the center of the top and bottom with the horizontal wire (LUX). When the film originals are fixed to the plate surface when they are properly registered, the l°th film original is accurately positioned and fixed at a predetermined position on the plate surface.

After completing the above operations, press Precent Counter C3.
While pressing the reference point return button of 21, hold frame 00
) and set the value of the second film original to \2, Y2.
→Call by pressing button C. Then, the same operation as described above is repeated, and the registration wire (10) is placed at the required position (
The horizontal wire (IOX) is set to move 25 cm downward from the reference line If registration is performed and the film original is fixed, the second film original will be accurately positioned and fixed at a predetermined position on the surface of the printing plate.

Thereafter, by the same operation, the 8th and 4th film originals can also be accurately positioned and fixed at the predetermined positions on the plate surface. Once these are completed, the four film originals can be fixed at the predetermined positions on the plate material surface. It is precisely positioned and fixed, and the plate material can be immediately applied to the printing machine.

In addition, if the above operation is configured so that multiple registration wires can be placed on the base surface, it will be possible to set the positions of multiple film originals simultaneously, and the efficiency of the amplifier will be further increased. I can figure it out.

Hereinafter, referring to FIG. 7, the procedure for registering by using a droplet and a water droplet will be explained.

For registration using water droplets, it is possible to achieve the purpose by using an ultra-fine knotted wire such as a piano wire as the registering wire, but as shown in the same figure, broken wire can be used as the registering wire. If a transparent strong thin material (34I) with a straight line (34') is used and configured in advance, when the register mark is superimposed on the registration wire, the broken line part (s4 ') Since the register mark C3nk of the film original (36) can be seen through one pass, the accuracy and workability of registration are exceptionally high.

In this embodiment, the register wire was driven using a pulse motor as the drive source, but scales were attached to the required locations, and the movement position of the register wire was confirmed using the scale. The present invention does not intend to make it manually driven, and the present invention naturally includes design changes within the scope of the idea of the pond water invention.

As detailed above, the present invention not only eliminates the creation of a mount as a means of registration, but also eliminates the work of scribing register marks on the plate material, and uses horizontal and vertical lines as a substitute for register marks. A register wire having a wire, that is, a cross-shaped register wire is arranged on a base, and connected to a driving means so that it can be set at a desired position. By simply aligning the register marks of the film original with the wire material, precise registration is possible, which greatly improves work efficiency.Moreover, the registration wire material itself has the features described above. This invention greatly improves the accuracy and ease of registering, and is an invention with outstanding practical effects.
