Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an image scanning recording device (hereinafter referred to as a color scanner), and more particularly to a method for recording register marks on a recording film for positioning a reproduced color image. .

(Prior art) When a color image is reproduced by multicolor printing, the original color image is separated by color using a color scanner, and multiple color separation printing plates such as yellow, magenta, cyan, and black are made. It is well known that the colors of the original painting can be reproduced by overprinting them on the same paper using corresponding colored inks.

In this case, it is necessary for the multiple color separation images to be printed in the same position and correctly aligned with each other, so-called "registration", and if the alignment is poor, the result will be "Color shift" occurs in printed matter, resulting in a significant drop in quality.

As a result, in order to obtain sharp images with no color shift on the printed matter, the [registration 1] work at the plate-making stage is important, and although this work often spans several steps, the most important Registration 1 work is usually carried out by "collection" or "
For example, as shown in FIG. 3, a layout transparent sheet film 4 corresponding to the size of the plate to be made is prepared, and register bins 5 and 5 are inserted into punch holes 6. 5 for positioning. The separation mesh positive film 3 for the first color plate is sequentially attached to this sheet film 4 with adhesive tape according to a required layout. Usually, a magenta plate is selected as the first color plate, and a magenta plate separation mesh positive film is pasted. When all the films 3 have been pasted, the magenta plate compilation work is completed.

Next, based on the magenta edition in which this collection has been completed,
Another transparent sheet film 4 is positioned and placed on top of this using the register pins 5, and another color separation mesh positive film 3 is placed on top of the magenta mesh positive film placed under the transparent sheet film 4. Paste it in register with the pattern, and complete the collection of the second color (for example, cyan) version.

The same applies to the third color (for example, yellow) plate and the fourth color (for example, black) plate. At this time, the registration of each pattern of the second to fourth color plates with respect to each pattern of the first color plate, which serves as a reference, can be accurately checked by the degree of consistency of the register marks 2, and the register marks can also be checked with each other. This can also be achieved by precise alignment.

The present applicant previously disclosed an invention described in Japanese Patent Application Laid-Open No. 54-46602 regarding a register mark recording method in a color scanner applied to register the reproduced color image.

However, since the register mark array (FIG. 5, 24) formed based on the above disclosure is of the same positive type for each color separation plate, the following inconvenience has occurred in the registration work.

In other words, the register mark of the first color plate serving as a reference,
If the second to fourth color register marks are both positive or negative type, the apparent line thickness due to misregistration or the apparent thinning of the line due to misregistration, respectively, should be matched. The registration work associated with the above-mentioned book collection work requires great care and attention from the operator. As a result, a decline in work efficiency due to the stress was unavoidable.

On the other hand, if the negative and positive register marks are overlapped for positioning, the amount of error can be further reduced, so many companies go out of their way to create reversal films. In this case, the extra film is a so-called disposable plate, and producing it requires extra materials and labor, leading to increased costs.

(Problems to be Solved by the Invention) The present invention has been made to solve the above-mentioned difficulties, and when recording register marks with a color scanner,
In a color scanner, the cross-shaped register mark of the disassembled version, which is the standard, is recorded in a negative type, and the cross-shaped register mark of the Mutsuike version is recorded in a bond type, making registration easier and contributing to improved work efficiency. The purpose of this invention is to provide a method for recording register marks.

(Means for Solving the Problems) The present invention uses clock pulses that are synchronized with scanning in the main scanning direction on the recording side. It counts to form line images at regular intervals parallel to the sub-scanning direction, and on the other hand, it forms line images in the main scanning direction at regular intervals in the sub-scanning direction, and the above two types of line images are combined to form a cross-shaped register. In a color scanner that records a mark outside the copy image area of a photosensitive material, outputting a signal to be recorded by combining the two types of line images,
A method for recording a Renoster mark in a color scanner, characterized in that the signal and a signal obtained by inverting the signal are selectively outputted, and a cross-shaped positive line image and a cross-shaped negative line image are recorded. be.

These recording image signals Y, M, and C include 1 as disclosed in Japanese Patent Publication No. 52-18601, for example.
The four-color image signals for scanning lines are stored in parallel once in the memory device 21.
The image signals Y, M, C, K are read out one by one one by one at a timing when one rotation period of the recording drum 14 is divided into four, for example, and inputted to the recording head 18 via the output drive circuit 22. Corresponding color separation images are arranged and exposed and recorded as a yellow version (0'l), a magenta version (M I ), a cyan version (CI), and a black version (KI), respectively.

In order to control writing and reading of the image signals Y, M, C, into the memory device 21, the original image drum 1 is used.
Rotary encoders 23a and 23b which are driven coaxially or synchronously with the recording drum 14 and the recording drum 14 are attached to generate control pulses that are synchronized with the rotation of the drum. for example,
The rotary encoder 23a outputs a large number of clock pulses (Pc) that are equally divided into one rotation period of the drum.
Generates a rotation pulse (Pr).

Figure 5 shows a color-separated image Y obtained by the color scanner in Figure 4.
l, M1. This is a schematic illustration of a film in which register marks are recorded by exposure at the same time as CI and KI are recorded by the method disclosed in the above-mentioned Japanese Patent Laid-Open No. 54-46602.

The photosensitive film 13 has color-separated images (Yl)MI, C, I along the circumferential direction of the recording drum (hereinafter referred to as the main scanning direction).
, KI are exposed and recorded. In this case, areas (T1) where an image is recorded by inputting an image signal to the recording head and blank areas (T2) between each image area are alternately arranged. In these blank areas (T2), as shown in the figure, the main scanning direction and orthogonal to this (hereinafter referred to as the sub-scanning direction)
Register mark rows 24 are recorded by exposing parallel straight lines 25 and 26 at regular intervals to each other, and the positional relationships between the straight lines 25 and 26 that make up these register mark rows 24 and each color separation image all match. control record and
The crosshairs of the register mark row 24 are used as register marks. In FIG. 5, a yellow plate area TY is arranged so as to include one register mark row 24 before and after the area T of one color separation image (for example, YI), and similarly TM, TC. , TK are installed in series.

During the above-mentioned plate collection work, each color plate area TY, TM, TC
.

It is cut into TKs and registered using this register mark row 24.

The exposure recording of the register mark row 24 is performed as follows.

First, to record the straight lines 25 in the sub-scanning direction, clock pulses PC at regular intervals that are generated synchronously with the rotation of the drum are used. That is, the clock pulses PC are counted based on the end of scanning exposure of each image area T1,

The present invention is based on the well-known technology described above and has been improved upon, and embodiments thereof will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a diagram of a register mark row formed based on the first embodiment of the present invention, where A is a positive type, A'
indicates a negative type register mark string. Although there is a difference between the transparent portion and the opaque portion of both lines, in the illustrated example, their thicknesses are equal to each other.

FIG. 7 is an enlarged view of a main part showing a mode in which portions A and A' in FIG. 1 are overlapped for the purpose of registration work. If there is a misalignment between the respective register marks, a blank gap 27 will appear, so it is only necessary to register them so that this gap 27 does not occur.

It is clear from FIG. 7 that more precise alignment can be easily obtained by using positive type and negative type register marks than by overlapping positive type register marks.

FIG. 8 is a control circuit diagram of an embodiment for appropriately selecting and recording the positive type register mark row and the negative type register mark row.

Next, the control circuit shown in FIG. 8 will be explained.

A clock pulse PC is input to the terminal 31, and the recording head (FIG. 4, 18) is input to the terminal 32 in the image recording area (TI).
During the scanning period, the low level of the signal CK is input. The low level of this signal OK is stored in the memory device (21)
Each color separated image signal (Y.

A circuit (not shown) counts and outputs timing pulses, the number of which is determined by the circumferential dimension of the tweet image, at the time when the timing pulse for reading out the images (M, C, K) is generated.

The signals input to the terminals 31 and 32 are input to the NAND circuit 33, and the NANDjjl path 33 outputs a pulse Hj while the recording head scans the blank area (T2). This pulse H1 is input to the counter 34 at the next stage.

The counter 34 receives the signal C8 via the inverter 35, inputs the pulse CK as a reset signal, counts the input pulses H1, and outputs one pulse H2' every time a certain number of N pulses are input. Output. This pulse H1' is input to the -stable multivibrator 36, modified into a pulse signal H2 of the required width, and input to the OR circuit 43. This pulse signal H2 is a straight line 25 in the sub-scanning direction (arrow F).
used as a signal for recording.

On the other hand, a one-rotation pulse Pr is input to the terminal 37, and a signal Dr for driving the recording head (FIG. 4, 18) in the sub-scanning direction (arrow F) is input to the terminal 38. The input is input to an AND circuit 39.

Therefore, one pulse is outputted from the AND circuit 39 for each rotation of the drum while the recording head is being driven, and is inputted to the counter 40 at the next stage.

The terminal 41 receives an output signal MS from a position detecting means such as a magnetic sensor disposed at a suitable position on the moving path of the recording head. This input signal MS is input to the counter 40 as a reset signal. Therefore, the counter 40 counts one revolution pulse Pr from the time when the recording head passes a certain point during its scanning stroke, and outputs a signal (2) having one pulse every fixed number N2. This pulse (1) is input to the -stable multivibrator 42, modified to a pulse signal V2 of the required width, and input to the OR circuit 43. This pulse signal V2 is a straight line 26 in the main scanning direction (arrow E).

The output signal (H2+V2) is outputted as is, a positive register mark is recorded, and when the signal tM is at a high level (when scanning and recording a magenta plate), the output signal 102 of the EX-OR circuit 45 is , is taken out as an inverted signal (H2+V2), is outputted to the recording signal output terminal 54 via the amplifier 47 and the switch 51, and a negative type register mark is recorded in the blank area of the magenta plate.

The manual switch 46 is a switch for switching between positive register mark recording according to the invention of the prior application and positive register mark recording including negative according to the present invention, and can be omitted.

Color-separated image signals Y, M, C, and K sequentially read out from the memory device (FIG. 4, 21) are input to the terminal 52 and output to the output terminal 54 via the switch 53.

Note that the signal CK input to the terminal 32 controls the switch 51 via the amplifier 49, and also controls the switch 53 via the inverter 48 and the amplifier 50, as is conventional.

Therefore, a color separated image is recorded in the image recording area T1, and a register mark string shown in FIG. 1 is recorded in the blank area T2 by the signal from the EX-OR circuit 45.

The negative type register mark in Figure 1 A' is
Since a thin transparent line is formed within the blackened area, if the positive type register mark of FIG. In order to avoid this inconvenience, the means of the second embodiment described below can also be applied.

(Second Embodiment) FIG. 6, AM to AK (although AK does not appear),

Each register mark string AY, AM, AC, AK is
For example, as shown in FIG. 6, AY is recorded before and after the yellow version image YI, and AM is recorded before and after the magenta version image MI, and the same is true for the cyan version and the black version. Negative cross lines 30 are arranged in each register mark row so as to have different phases depending on each color plate.

Note that although there is a difference in the transparent and opaque portions of both lines, in the illustrated example, their thicknesses are equal to each other. When performing registration work using this register mark, as in the first embodiment, the register mark (
Therefore, there is no need to specify the reference color separation plates, and accurate registration can be achieved using any of the register marks, similar to the embodiment shown in Fig. 7, and when four plates are overlapped at the same time. It also has the advantage of being easy to register. In particular, in this case, the inconvenience of difficulty in visual recognition in the first embodiment is solved, and after the positive type register marks are used to achieve highly accurate registration, more precise registration can be performed using the positive type and negative type register marks. By performing registration, the required high precision alignment can be achieved more quickly.

FIG. 9 is a diagram showing an embodiment of a control circuit for recording the series of register mark rows.

FIG. 9 will be explained below. Note that the reference numbers and symbols used in FIG. 9 that are the same as those in FIG. 8 represent the same circuit configurations and signals, respectively, and the explanation of parts configured with the same circuits will be omitted since it will be redundant.

2+V2) is output.

The output signal (1) from the counter 40 is also input to the counter 61 and shift register 63. The start signal MS input to the terminal 41 is input to the counter 61 and shift register 63 as a seven-step signal.

From the counter 61, two types of signals, for example, the number of pulses of Vl, are divided into 1/2 and 1/4, respectively, and the required number of pulses (pitch L of vertical line 26) is output from the rising edge or start signal MS.

Note that in order to obtain such a signal, a decoder can be used instead of the AND gate 62 and the shift register 63.

A signal tY corresponding to the yellow plate area TY is inputted to the terminal 71 and inputted together with the signal VY to the AND circuit 64, from which a signal [Y·vY (signal LY and vY are ANDed) is outputted. , are input to one input terminal of the OR circuit 68.

When the output signal of this OR circuit f%68 is low level, E
The X-OR circuit 45 outputs the signal (V2+H2) as is, while when the output signal of the OR circuit 68 is at a high level, the EX-OR circuit 45 inverts the signal (V2+H2) and outputs it. Therefore, when scanning and recording the area indicated by arrow 105 in FIG.

(Third Embodiment) In the first and second embodiments, the line widths of the pop and negative register marks were recorded equally, whereas in this embodiment, the main part is shown in FIG. like,
The line width of the negative Renoster mark is symmetrically thickened compared to the line width of the Bonn register mark. In the register marks of the above embodiments, if one or both of the positive and negative register marks becomes thickened, accurate registration may not be possible using register pins. However, in this embodiment, the line width of the negative register mark is symmetrically thicker than that of the positive register mark, so even if printing thickens, accurate registration is not possible. It has the characteristics of being able to

The control circuit for recording such a negative register mark string, for example, as shown in FIG. - The timing at which the stable multivibrators 36 and 42 are shifted forward by a time corresponding to 1/2 of the dimension for which the line width is to be thickened; Increase the Hatake cutless width by the time corresponding to the dimension to be increased, and reduce the number of input pulses to the counters 34 and 40 appropriately so that the pitches and 7s of the register mark to be recorded are the same as those of the positive ones.

Further, in the first embodiment shown in FIG. 1, the register mark row is made up of only negative register marks, but it can also be constructed to include some positive register marks, if necessary.

For example, it is also possible to use a negative and positive register mark row shown in FIG. 6.

(Effects of the Invention) Since the present invention is configured by the method described above, the register mark used in the registration work is formed of a cross-shaped positive line image and a cross-shaped negative line image, and the register mark is formed of a cross-shaped positive line image and a cross-shaped negative line image. When aligning and registering, it is possible to easily identify poor alignment, so unlike conventional methods, the apparent thickening or thinning of the line due to misregistration will not be overlooked, resulting in high accuracy. registration becomes possible.

Therefore, it is of great practical value, particularly in improving the efficiency of registration work during book collection work, or contributing to saving time and cost for creating a master plate, such as an inverted magenta plate, for registration purposes.
