Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that automatically lays out the printing position of a film original plate to be printed onto a printing plate in a printing plate process for producing a printing plate in offset printing.

Conventionally, in the printing plate process, the printing position of the film original plate is determined.The layout work is the size of the film original plate, the number of sides, Based on data such as the paper size used, the specification of the printing machine used, and other data such as notes and layout specifications written in the case of special layouts,
The operator investigated the specifications of the printing press used and calculated the layout position using an electronic desktop calculator or by hand according to a predetermined layout procedure. After calculating the layout, a printing plate mount (or marking mount) is prepared in the printing plate process, which is used to make markings on the printing plate necessary for positioning when printing the film master onto the printing plate.
There is a task of searching the mount ledger for a marking mount that matches the layout. At this time, if there is no marking mount that matches the layout results, it is necessary to create a new mount, and at this time, the marking positions are calculated in detail from the layout results and a design sketch of the marking mount is created.

As described above, in the conventional method, an unskilled person cannot perform the work smoothly until he memorizes the work procedure, rules, specifications of the printing machine, etc., and it takes a long time to learn the work. In addition, even for an experienced person, this series of tasks takes time, and it is also time-consuming to organize the ledger of the marking paper that is provided.

In view of the above points, the present invention enables even unskilled workers to perform layout work easily and automatically, does not require much time, and automatically searches for the necessary marking paper or assists in the management of marking paper ledgers. The purpose is to provide a device that can do this.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an automatic layout device.

The layout drawing, the type of data to be input next,
A display device 100 that displays various messages such as menus, a floppy disk device 200 that stores programs and various data necessary for work, a magnetic card device 300 that stores the results of automatic layout, and a computer that stores calculation results. Printer 400 that prints out figures and numbers
and a computer main body 500 that executes programs stored on the 70TB disk and performs various calculations.

Calculation refers to contents including calculation of layout position and correction and registration of recorded contents of floppy disk 200.

FIG. 2 shows a flowchart of the control program of this device.

Layout determination by this device is performed as follows.

A. Data Registration Basically, the layout (layout) of printing a film original onto a printing plate used in a sheet-fed printing press is such that the Y-axis is symmetrical with respect to the printing plate, as shown in Figure 3. position,
The Y-axis coordinate axis is set at the start position of the effective printing range of the occlusal edge, and the printing plate is symmetrically distributed in the left and right directions of the printing plate around the Y-axis, and the printing plate is placed on the occlusal side. When placed in the vertical direction, the Y-axis and the bottom of the surface, the lowest step, and the bottom edge of the surface are aligned, and the surface is printed above this point.

In a rotary printing press in which the paper is cut to a length corresponding to the length in the rotational direction of the printing plate and then ejected, the Y-axis is positioned symmetrically with respect to the printing plate, as shown in Figure 4. The coordinates of the Y axis are set at the center position in the circumferential direction of the printing plate cylinder when the printing plate is mounted on the printing press cylinder, that is, the center position of the paper that is cut and discharged, and In both directions, the surfaces of the burn-in are basically axially symmetrical.

In the rotary press 811 machine, which cuts the paper into half the length corresponding to the length in the rotational direction of the printing plate and outputs it, the Y-axis is positioned symmetrically with respect to the printing plate, as shown in Figure 5. In this case, there are two Y-axes, and the first Y-axis is on the bottom side of the printing plate (biting side).
1 at a position corresponding to the center position of the paper to be cut first. The layout coordinates of the second In the vertical direction, the burning is based on the number of surfaces (if the number is even, half of the surfaces are symmetrical about the first Y axis, and the other half are symmetrical about the second Y axis). If it is an odd-numbered side, it is symmetrical with respect to the intermediate position between the first and second Y axes. ;be.

As described above, printing presses are roughly divided into three types based on layout coordinates and layout basic methods. In addition to coordinates, there are other data that must be allocated at times, such as the size of the printing plate, the effective range for printing on the original film, and the area of the paper that cannot be printed, but these data including the coordinates are It is unique and unchanging for each printing press.

In addition, the L-shaped register mark that the inventors have proposed so far is formed on the printing plate, and this mark is optically detected by a sensor when the printing plate is mounted on the plate cylinder of the printing press. The formation position of the L-shaped mark used in the method of automatically registering multicolor printing is also considered to be unique to the machine specifications of the automatic register adjusting device used, that is, similarly unique to the printing machine. Therefore, it would be inconvenient to enter these data every time they are allocated, so they are registered with a representative number or name, and from then on, a series of data can be used simply by specifying the representative number or name. Registration of these data is performed as follows.

(1) Menu displayed on the display according to the printing machine data registration program (1. Inscription mode, 2. Data mode, 3.
Select the data mode using the input device from Cart Yomido Remote, that is, press the 2 key on the keyboard and press the ENTER key. The menu that appears next (1,
Teaching, 2. Select 1 from (check). The menu that appears next (1, Pre-teaching, 2
．． Select box 1 from (machine teaching). This will change the mode in which you can register printing press data, and the message ``Enter printing press number'' will be displayed. This means "specify the representative number" for the series of data you are about to register. Enter the optimal value at 9.

Next, the message "Specify the type of printing press" will be displayed, and the menu (
11 sheet-fed presses, 29 rotary presses, 3. B vertical full-rotary press) is also displayed, and the type of printing press to be registered is specified. Here, menu 3 is a printing machine that cuts the paper into half the length corresponding to the length of the printing plate in the circumferential direction. From now on, when specifying the size of the printing plate, the effective printing range, and the position of the L-shaped mark for a two-sheet-fed machine, the length of the printing plate excluding the effective range from the edge of the printing plate, the unprintable width of the paper, and the ring If a turning machine is specified, the length from the edge of the printing plate to the position corresponding to the center in the flow direction of the paper to be cut and discharged; if a B donation rotary press is specified, the length of the printing plate Sequentially input the length from the occlusal end to the position corresponding to the center in the flow direction of the paper to be cut and discharged in the "th" and "M2" according to the instructions on the display for the type of data to be input. Go. When all data input is completed, the input data is displayed in the form of a list, and the operator confirms the input data. If there is an incorrect input, it is possible to re-enter by correcting the display. When the check is completed, press the "Check Finish" key and the data will be registered on the floppy disk. At this time, if data has already been registered with the same representative number, an "error" message is displayed and an instruction is given to change the representative number. At this time, the operator changes the number and presses the "Check Complete" key. When the writing of data to the floppy disk is completed, a menu (1. Teaching, 2. Teaching) is displayed on the display.

If you specify 1, you will be returned to the beginning of registration mode and asked for your representative number. If you specify 2, program execution returns to the mode-specified menu display that was initially displayed. If you want to continue registering another printing press, specify 1 and you can continue registering data one by one. If all registrations are completed, specify 2. With the above steps, the printing machine data can be registered, and the preparations for printing the printing plate 1 and performing the surface layout are completed. Registration of printing press data is not always necessary as it is performed only when this apparatus is installed or when a new printing press is installed.

(2) Registration of machine data If you specify 2 from the menu (1. Pre-teaching, 2. Machine teaching) that appears after specifying the data mode and then the teaching mode, you will be able to register the device data. Become. This specifies the environment around the device. For example, the instructions include not using a magnetic card input/output device or not using a printer.

As a result, the contents of the menu displayed as the program progresses will change depending on the specified surrounding environment.You can also specify the length of the marking line.

Of the menus (1. Teaching, 2. Check) displayed after the data mode, 2 is a mode for extracting the data registered in Menu 1 and checking and changing the contents.

In the case of a B0 sheet-fed printing press (1) Determining the layout (allocation is calculated) Next, the actual layout is calculated, but the data that is the basis for the layout (printing machine used, size of the original film, The number of pages for printing, the spacing between prints, shifts in horizontal and vertical directions, binding format, paper size to be used, and other special instructions (detailed instructions for printing) are included in the work instruction sheet for the printing plate along with the film original plate. It is written and submitted to the printing plate department where this device has been installed.

If the original film size to be printed is of one size and you want to layout it in a square pattern (regular imposition), select the menu shown on the display (1° scribe mode, 2.
data mode, 3. Specify the marking mode (1) from the Cartoon Remote), and then specify the regular imposition mode (1) from the menu that appears (1. Seisoku Mentsu, 2. Hensoku Mentsu). If you specify 1, the next screen will ask you to enter the printing press number. This is the representative number that was first entered when registering the printing press data mentioned above, and the number corresponding to the printing press to be used is entered here. When input, the device searches for the data with the input number from the floppy disk, reads it into the device itself, and displays the printing press number, printing plate size, printing plate shape, and L-mark position data on the display. If it is not zero, a picture of an L-shaped mark is displayed and the message ``Enter the required size of the film original'' is displayed.

If you enter the numerical value listed on the work instruction form, a message will appear saying "Enter the number of sides for printing," so enter this next. Then, according to the basic method described above in the coordinate system unique to the printing machine, the position of each printing surface is automatically calculated so that the surfaces are in contact with each other, and the layout result is displayed as a picture. displayed within the border of the printed version. At the same time, the size of the film master input, the number of sides for printing, and the center distance between each side are displayed, and the menu for ``Are there any mistakes in the input data?'' (1. No mistakes, 2. All mistakes) is also displayed. . The operator checks the display and selects 1 or 2. If you select 2, you will be asked again for the size of the original and the number of prints. If you select 1, a special designation menu will be displayed next.

If the printing machine you are inputting is a sheet-fed machine, the menu will be 1, dovetail, 2. 3. Kentoukagen, 4. It's exciting. In the automatic layout calculations so far, each side is laid out so that they are in contact with each other, but if you want to leave space between the sides when printing, specify 1 in the menu,
If you input the position and width where you want to increase the spacing, the position will be automatically adjusted accordingly and a corresponding picture will be displayed on the display. During this series of operations, the operator is instructed each time what data should be input to the display via a message, so the operator can input the desired numerical values in accordance with the instructions. This is the same for any work in any mode.

If you want to shift the entire layout horizontally or vertically, specify 2 and enter the direction and amount of shift, and the position will be automatically adjusted accordingly and a corresponding picture will be displayed on the S display. If you want to move only a certain laid out surface by a minute amount, specify 3. This is to correct in advance the print position of the image due to the peculiarities of the printing machine. After specifying 3, if you input the number of the surface you want to move and the amount of movement according to the displayed message, the position will be corrected accordingly and a corresponding picture will be displayed on the display. However, at this time, if the amount of movement is small and is below the resolution of the figure on the display, it cannot be displayed, so "Kagen" is displayed on that side to indicate that it has been moved, and the input data is displayed as a numerical value. It is supposed to be done.

After completing the above special specifications and checking the allocation status, 4. Specify Owari.

(2) When data transfer 4 is specified, a menu regarding whether or not to transfer data is displayed next. The menu is 1. Jiki card success printout, 2. Jiki card success, 3. Printout, 4. This is Tensou Shinai. When 1 or 2 is specified, a message saying "Set the magnetic card" is displayed, and when the magnetic card is inserted into the magnetic card device, the results of the layout so far are written as data and ejected. Next, in order to check the written content, the message ``Insert a magnetic card'' is displayed, and when the card is inserted, the contents of the card are read and compared with the written data to check the writing. If there is an error in writing, a message to rewrite will be displayed, and if there is no error, if 1 is specified, the layout result will be printed out to the printer, the layout mode will end, and the menu that was displayed at the beginning will be displayed. Program execution returns to the display. If you specify 3, the layout result is printed out and the program execution returns to the menu that was displayed at the beginning.

In the case of a C9 rotary press If the printing press being input is a rotary press or a B donation rotary press, the content after the special designation menu display will be different from that of a sheet-fed press. The displayed menu is 1.7. 3. Dobuire, 4. 5. Menus 3, 4, and 5 are the same as those for sheet-fed printing presses, but modes 1 and 2 are added.

In rotary presses and B-vertical rotary presses, after printing, the paper is generally cut, folded two to four times, and then discharged.

The number of folds is determined by the size of the printed matter, and the method of folding is specified by the binding form of the printed matter.

The method of folding printed matter in bookbinding formats such as flat binding and wireless binding is completely symmetrical folding.

In the case of this type of folding, the position of the image on each page must be printed so that the left, right, top and bottom margins are even. If the layout is made by simply inputting the size and number of impositions of the original film plate using this device, all sides will be in contact with the center of the printing plate, so if the printing plate is folded in this state, the margins of the page will not be even. For this purpose, mode 1, Habajidugaisandpuile, is used to make the margins even.

If you specify this mode, the message ``Enter the paper width'' will be displayed. When you input the paper size, the system automatically calculates the position and width of the margins based on the size of the original film and the number of impositions, corrects the layout position, and displays the corresponding picture on the display.

The method of folding printed materials with a center-edge binding method is to fold the printed materials in the binding machine where they are not folded overlappingly (the 6th fold), which is called a wrap.
It is asymmetrical because it requires

For a typical 16-page paperback, this device only requires inputting the size of the original film plate and the number of impositions, and all sides are laid out in contact with the center of the printing plate (center of the coordinate axes). ” should be selected. However, before the paper is cut perpendicular to the flow, it is cut horizontally evenly on both sides of the flow, and after horizontal and vertical cutting, the paper is folded once vertically and once horizontally. In a so-called "8-page double-column print", the left and right sides of the coordinate Y-axis and the axis of rotation of the printing plate must not touch and have gaps (white parts that are not pictures). Also, the position of the burn-in must be shifted to the left or right depending on the width of the gutter. For such printed matter, if you specify 2 on the menu and enter the width of the paper, it will automatically calculate the gutter width and shift amount from the size of the original film, the number of impositions, and the paper, and correct the layout position. A corresponding picture will also be displayed on the display. Menu 3 or 4 if there is any other special position designation.
You can perform the same work as with a sheet-fed machine according to the instructions using the .

Enter the printing press number, film original size, and number of impositions to be used as described above, and while checking the layout status on the screen, enter the paper size interactively using various special specification modes and automatically correct it. complete the final assignment by making corrections by inputting numerical values. In most cases, layout is completed by simply entering the printing press number, film master size, and number of impositions without making any special specifications.From then on, you can simply specify the data transfer menu and the layout work can be completed. Complete.

D. Irregular Surface Addition Next, we will explain the layout method when the size of the original film to be printed is not the same size or when there is a special designation for the printing arrangement rather than repeating squares, which is an accompanying function.

The coordinates of each surface are calculated in advance by considering the layout based on the size and number of impositions of the film original plate according to the coordinate system of the printing machine to be used.

If an arrangement shape is specified, the coordinates of each surface when arranged in the coordinate system of the printing press are calculated according to the arrangement shape.

Specify 1 from the displayed menu (1. Marking mode, 2. Data mode, 3. Cart reading remote), and then select 1 from the displayed menu (1. Marking mode, 2.
．． Specify 2 from Hensoku Mentzke). You will then be prompted to "Enter the number of the printing press you are using," so enter this. The device extracts the relevant data from the registered data, displays the shape and data of the printing plate on the display based on that data, and lays it out.
Please enter the size of the original film.'' appears. When you input the size, it will ask you for the coordinate position of the first side, and once you input this, it will ask you the number of times to repeat the layout in the horizontal and vertical directions in order to repeat the layout of this first side. For example, if a layout as shown in FIG. 7 is specified, three other pages of the same size as the first side are lined up horizontally. You can input the size and coordinates of all the surfaces from the 1st to the 6th surface at any time, but if the same size is arranged regularly, the size of the surface, the first position of the arrangement, and the repeat If there is data on the number of times, the coordinates of other surfaces can be automatically calculated, eliminating the need to specify coordinates from time to time.

Using the example in Figure 7, to explain an example of input when printing this on a sheet-fed printing machine, when an input message for the size of the first side appears, the size is set to X = 230 and Y = 46.
Enter as 0. Next, when a message to input the coordinate position of the first surface appears, input X=-345 and Y=230. Next, when a message appears asking you to input the number of repetitions, the lateral force direction is 4. Enter vertical direction 1 (Figure 8). This is the second ~
The coordinates of each of the four sides are automatically calculated, and the laid out picture and data are displayed on the display. The operator checks the displayed contents and, if there is a mistake in input, selects 2 from the displayed menu (1, No mistake, 2. Yes, mistake) and re-enters from the first page. If there are no mistakes, select 1. Based on this, a menu (1, yes, 2, no) is displayed asking whether there are any surfaces to be added and laid out. In the example of FIG. 7, there are 5th and 6th sides, so 1 is selected. Then, the plate size, coordinate position, and number of repetitions of the fifth side are sequentially provided, so set this to the plate size of 460
230, coordinates -230°575, repeat horizontal 2, M
Enter with l (Figure 8).

As a result, the position of the sixth side is also calculated, and the laid out picture and data are displayed on the display. Check the display and if there is an input error, select 2 from the displayed menu (1. No error, 2. All errors) and re-enter from the 5th page. If there is no input error, select 1. Then, a menu will be displayed asking whether there is something to add or not (1, yes, 2, nothing). In this example, since the seventh surface does not exist, 2 is selected. If you select 2, the next menu will be 1. Lenteidou (Lenteeidou), 2. Ichi Shuusei (
Tandok), 3. Owari is displayed. In normal work, the layout position is calculated in advance and the data is input, so 3 should be selected. Modes 1 and 2 are available in case you want to correct the imposition position after the entire imposition is finished for some reason. Mode 1
For example, when you want to move the second side to the left in the layout shown in Figure 7, the 0 function will move the 3rd and 4th sides on the side to be moved by the same amount if you enter the plate number 2 and the amount of movement to the left. It is something. In other words, even if one surface is moved, related surfaces are also moved by the same amount so that they do not overlap with other surfaces. In mode 2, only the specified surface is moved independently, and it can also be moved so that it overlaps with other surfaces. Mode 1 if especially necessary. Modify the layout using mode 2.

All operations at this time can be done by inputting data according to the contents shown in the message.

This mode is convenient when controlling an automatic marking device that stores the layout results in a magnetic card and automatically marks a printing plate based on the data on the magnetic card.

This completes the allocation.

E. Output of layout (allocation) results If you print out the layout results, the dimensions for creating a marking mount are also shown, so you can create the mount based on this.

After creating the mount, if you organize and bind the printed results on the printing machine, this will become a ledger for the marking mount. If you examine this from now on, you will be able to obtain information about the preserved mounts. By comparing the results displayed on the screen after layout with this device and the printed results of the bound ledger, it is possible to determine whether or not the mount has been saved. If there is a result stored in the ledger that matches the result displayed on the screen, that storage mount is used. If there is no match, print out the results and create a new mount.

If you want to store the results on a magnetic card, select the menu that appears at the beginning (1. Marking mode, 2. Data mode,
3. By specifying 3 from Cart Yomid Remote and inserting the magnetic card with the results memorized into the device's magnetic card device, the layout results can be reproduced on the screen, and it is also possible to modify the layout from the reproduced state. It is.

Furthermore, this magnetic card can also be used as a data card for controlling the marking position of an automatic marking device that automates the marking work that is performed manually by an operator using a marking mount.

FIG. 9 shows an outline drawing of the automatic marking device.

The device M has a machine base 0 with legs 10a, 10a,
Guide rails 12, 1 are placed along the front and rear ends of this machine base 10.
2, and the front and rear ends of a slide rod 13 are slidably engaged on these guide rails 12, 12, and this slide rod 13 is prevented from coming off upward by guide plates 12a, 12a. . The slide bar 13 has a writing section 15 for marking linear registration marks and color registration marks.
and a register mark reading sensor 16.
4 is slidably supported.

An operation panel P for operating a microcomputer (not shown) is provided on one side of the guide plate 2. By operating this operation panel P, the slide rod 13 is moved to the guide rail 12.
The head portion 14 automatically slides along the slide rod 13, respectively. A magnetic card insertion slot for reading magnetic cards is also provided.

The operation of this device M is as follows. Press the magnetic card reading button on the operation panel P and insert the magnetic card from the card insertion slot. If there is no error in reading the magnetic card, place the printing plate on the machine stand and press the start drawing button on the operation panel. As a result, the device automatically performs marking according to the layout data on the magnetic card.The automatic marking device uses a rotary printing press to optically detect the registration marks printed on the paper using a sensor and perform automatic registration. It also has the ability to form color registration marks on printing plates that can be printed on paper. Data for controlling the writing function of this color registration mark can also be created by an automatic layout device and stored on a magnetic card. In this case, the control flowchart of the automatic layout device is as shown in FIG. This is the flowchart of FIG. 2 with the addition of a routine for automatically specifying a color registration mark writing position after layout and a routine for individually specifying a writing position.

The magnetic card can also be used as a control card to control an automatic stacking device for marking paper. In this system, when a card is input into an automatic stacking device, it is determined whether or not the intended marking paper is stored, and if it is, the marking paper is automatically taken out.

There is also a method of registering the layout results on a floppy disk without using a magnetic card. When a new marking board is created, the data is registered on the 70-bit disc. In this way, by comparing the layout results with the data on the floppy disk, it is possible to automatically determine whether or not the marking board has been saved, thereby eliminating the need to manually search the ledger. If you have a lot of data to register and can/can store it on a floppy disk,
A large-capacity hard disk device may be used instead of a floppy disk.

In this embodiment, a magnetic card is used as a data storage means, but other known means such as a paper card, paper tape, magnetic tape, semiconductor storage element, etc. may also be used. Furthermore, the data may be transferred directly to the automatic marking device without using these storage media, such as online transfer using a cable, or online transfer using light, radio waves, or sound waves.

Furthermore, the position data of the register marks detected from the printing plate is
Although this information is registered in advance on the floppy disk along with other printing machine specific data, it may also be specified when inputting the layout. This is advantageous in changing the position when used for other purposes, such as changing the position due to changes in the paper when detecting the register mark from the paper surface, for example.

With the present invention, if you register the printing machine data in advance in this way, basically all you have to do is input the size of the original film plate and the number of impositions, and the printing layout will be automatically calculated, so the operator can There is no need to be an expert when it comes to attaching, and the work can be done quickly and in a short period of time.
