Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing and plate making layout device, and more particularly to a layout device for laying out image data according to the contents of a designated layout sheet.

(Prior Art) In recent years, with the color separation of the document by the scanner, the printed matter 1
2. Description of the Related Art A printing plate making layout device that synthesizes image data for each item by computer processing is used in the field of printing plate making. In this layout apparatus, a computer having a page editing function is connected to the scanner, and the image data captured by the scanner is given to the computer, processed such as layout, and then output to the scanner.

FIG. 23 is a schematic diagram showing the configuration of a general printing and plate-making layout apparatus. In the figure, 160 is a layout section, 170 is a tablet digitizer, and 180 is a scanner section. As shown in the figure, the layout section 160 comprises a computer 161, and memories 162, 163, a display 164, a joystick 165 and a keyboard 166 connected to the computer 161, and a tablet digitizer 170 comprises a cursor 171, an input surface 172, and The surface 172 has a mount area 173 and a menu area 174.
Is set. The scanner unit 180 includes an input drum 181, an output drum 182, and interfaces 185 and 186, and the interfaces 185 and 186 are connected to the computer 161. The computer 161 is composed of an input computer, a layout computer and an output computer (none of which is shown).

In this layout scanner, image data editing work and the like are performed in the following manner based on various originals, layout designation sheets, and other instructions. First, the input drum 1 of the scanner unit 180
A manuscript is pasted on the 81 at an angle designated by the layout designation paper, and the image data of the manuscript is taken into an input computer (not shown) of the computer 161 via the interface 185 and stored in the memory 162. The image data is taken in from the original in a slightly larger range than the actual trimming range based on the designated layout sheet (not shown), and the computer 16 is used later.
Accurate trimming is performed by the layout computer (not shown) of 1.

The memory 162 in which the image data is written is separated from the input computer and connected to the layout computer. As a result, the image data written in the memory 162 is displayed on the display 164. The operator observes this display image and operates the joystick 165 while referring to the layout designation sheet to move the cursor to designate the trimming range and the position of the halftone dot. In addition, the keyboard 166 is used to specify the magnification, plate color, halftone dot ratio, and the like.

Since the data layout-processed according to these specifications is written in the memory 163, the memory 163 is disconnected from the layout computer after the writing is completed, and the computer 16
1 output computer (not shown). As a result, the data in the memory 163 is taken out through the output computer and the interface 186, and the trimmed-layout image is output to the film set on the output drum 182 of the scanner section 180.

Also, the above work done using the joystick 165 and keyboard 166
It can also be performed by operating. That is, the layout designation sheet is set in the mount area 173 of the tablet digitizer 170, and the cursor 171 is operated to select the position data of the pattern drawn on the layout designation sheet and various menus set in the menu area 174. Enter it.

Here, when the image data of the original is read from the input drum 181 of the scanner unit 180, it is necessary to first attach the original to the input drum 181 at an angle designated by the layout designation paper.
Then, the worker attaches the original document based on visual inspection. That is, the inclination angle of the figure drawn on the layout-designated paper is measured by a protractor, and the original is pasted on the input drum while confirming the angle of the original using the protractor or the like based on the measured value. Therefore, there is a problem that the work is complicated and the original cannot be attached at an accurate angle. Then, in order to improve the work of sticking the original to the input drum of this scanner, a magnification measuring machine having a function of projecting the original is used, and a data tablet is provided on the projection surface of the magnification measuring machine to attach the original sticking line and trimming. A device for outputting a sheet in which a range is drawn has been proposed by the present applicant as the invention of Japanese Patent Application No. 60-137434.

Next, in the layout work using the computer 161, it is necessary to perform accurate trimming of the captured image data and give an instruction such as shading. This layout work is performed by displaying an image on the display 164 and operating the joystick 165, so the position specification of the trimming range tends to be inaccurate, and not only skill is required for the work, but also the computer 161 can be used for a long time. Since it is occupied, there is a problem that an expensive printing plate making layout device cannot be used efficiently. Therefore, as an improvement of this layout work, a dedicated data input device is provided to record various layout data on a recording medium,
An apparatus for providing layout data to a computer via this recording medium to perform layout processing is Japanese Patent Application No. 59-2130.
No. 99 invention is proposed by the applicant.

(Problems of the prior art) However, the device of Japanese Patent Application No. 60-137434 and Japanese Patent Application No.
This is not only an expensive device as a whole, but also a device different from the data input device in No. 59-213099. In this regard, there was a problem that the work as the preparatory work could not always be performed efficiently.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and various layout data instructed by a designated sheet of layout can be input at the same time as the magnification and angle of the original are measured, and the layout by the computer is based on the input data.

The mouse 31 corresponds to the coordinate designating means in the present invention.

Next, the operation of the apparatus shown in FIG. 1 will be described. Third
The figure is an explanatory view showing an operation in the original sticking sheet creating apparatus A.

First, the designated layout paper RS is set in the mount area 12 of the data tablet 9 (S1). In the figure, the designated layout paper RS and the mount area are the same. A ruled line indicating a range to be trimmed of the original and a simple graphic showing the outline of the pattern are drawn on the layout designation paper RS.

Then, the position data of the ruled line indicating the trimming range and various layout data are input from the cursor 11 (S2).
At this time, regarding the input of the position data indicating the trimming range, a simple input method of the position data can be adopted if the trimming range is one of several predetermined shapes, for example, a rectangle. That is, for example, the "rectangle" of the first menu area 13a is selected by the cursor 11 and only two vertices of the upper left corner and the lower right corner of the rectangle are input with respect to the position. The input of various layout data is performed in the second menu area 13b. The input in the second menu area 13b is data used in the layout apparatus B thereafter (for example, document number, magnification, halftone dot percentage, etc.).
Is. Thus, the input using the data tablet 9 is processed by the CPU 14 and recorded on the floppy disk FD via the floppy disk device (S3). The floppy disk FD corresponds to the recording medium of the present invention. The floppy disk FD is moved to the layout device B and the recorded contents are used. Further, this recorded content is given to the plotter 18 or the mask cutter 19 and is also used for photographing and burning of the character, but the character is not particularly related to the trimming layout in the present invention, and therefore detailed description thereof will be omitted.

Next, a document such as a color film is set on the document holder 5 (S4), and the image I of the document is projected on the surface of the designated allocation sheet B set on the data tablet 9 of the workbench 2.

Then, the manuscript number is input by the ten keys or the keyboard 16 provided in the second menu area 13b (S
5) After that, the magnification adjusting switch (not shown) provided in the magnification measuring machine 1 is operated to match the design of the original image I with the layout designating graphic drawn on the layout designating paper RS. To do so. In addition, the matching of the positions at this time is performed by shifting the designated allocation sheet RS on the workbench 2.

After this, the magnification display switch (not shown) of the magnification measuring machine 1
When is operated, the magnification at that time is displayed on the magnification display 7 and the magnification data is taken into the CPU 14 and further recorded in the floppy disk FD (S6).

As already described, the above-mentioned operation is almost the same as that of the known magnification measuring machine, and the following operation is not necessary for a document for which angle setting and trimming range setting are unnecessary.

Next, when various position data on the designated allocation sheet RS for calculating the original sticking angle and the trimming range are input (S
7) At this point, the CPU 14 starts the processing of the position data and the magnification data, and calculates the sticking line data and the trimming range data of the document (S8). Next, the output position data on the sheet W of the sticking line and trimming range of this original is input and taken into the CPU 14 (S9).

When the sheet output switch (not shown) of the magnification measuring machine 1 or the keyboard 21 is operated, the data from the CPU 14 is sent to the control circuit of the XY plotter 17, which starts the graphic output operation by the XY plotter 17. Then, the hard copy in which the figure showing the original sticking line and the trimming range is drawn at the specified position on the sheet W is completed (S1
0).

After that, when the magnification of the next original is to be measured, the process returns from step S11 to step S4, and the operations up to step S10 are performed. In this case, when the output position data is input in step S9, since the sheet W is drawn with the figures indicating the pasting lines and the trimming lines of the document input up to the previous operation, refer to this figure. It is possible to easily input desired output position data.

In this way, when a series of operations are repeated by repeating the predetermined document magnification measurement operation and the like, the end operation is performed (S1
1).

FIG. 4 is an explanatory diagram of the menu setting operation performed prior to the data input in step S2 of FIG. As shown in the figure, this menu setting first sets the menu area (S2
1) Then, the menu area is divided and a menu item is assigned to each divided area (S22).

FIG. 5 is an enlarged view of the input surface 10 of the data tablet 9.

As shown, the input area 10 has a mount area 12 and a first menu area.
13a and the second menu area 13b are set. Mount area
12 is set by inputting three points A1, A2 and A3 with the cursor 11 in accordance with the designated allocation sheet RS. Then, it is used for inputting the position data by using the layout designation sheet RS itself. In the first menu area 13a, figures frequently used in the data tablet 9 are set as its items. Here, each item is a rectangle, a circle, a polygon, a straight line .... The mount area 12 and the first menu area 13a described above are included in a normal data tablet.

On the other hand, the second menu area 13b is newly adopted in the present invention. However, since the numerical input is conventionally used, the part excluding the numerical area is added by the present invention. And the menu item is a pattern number, a scaling factor (%), halftone → halftone%, layout rule items such as live ruled color, plate color, specific point, and operation items such as terminator and end point. In addition, color items C (cyan), Y (yellow), M
(Magenta) and K (black). In these items, 0 to 9 for inputting numerical values, decimal point, and delimiter of numerical values are shown.
In order to provide the area to which TAB is added, the second menu area 13b is set by the points B1, B2 and B3, which is divided and each item is assigned to each divided area.

By this menu setting operation, the data tablet 9 having the function required by the layout apparatus B according to the present invention is set.

FIG. 6 is a flow chart showing a data input operation performed using the data tablet 9 in which the above menu is set and an operation based thereon, and the data input in step S2 of FIG. 3 will be described accordingly.

First, the plate coordinates are input (S31). The printing plate coordinates are the coordinates of the mount area and indicate A1 to A3 shown in FIG. These 3
The point is entered with the cursor 11. Next, the plate color is input (S32). In the figure, an example of cyan C is shown.
The plate color is 10% cyan. In this case, with the cursor 11, "plate color", "C" in the second menu area 13b,
Specify "1", "0", and "TAB" sequentially.

When the plate color input is completed, the graphic is input (S34).
The figure refers to a figure indicating a trimming range and other figures drawn on the layout-designating sheet RS, and is a rectangle here. Then, after the "rectangle" in the first menu area 13a, the cursor 11 inputs the upper left and lower right two points of the rectangular trimming range on the layout designation paper RS.

There are cases where this figure is a pattern and cases where it is screened. In the case of a design, image data will be imported from the original later,
In case of halftone dot, it will be painted in the specified color.
Therefore, it is judged whether or not the screen is shaded (S35), and an operation is performed according to the judgment. If it is not shaded, it is a pattern. In this case, a pattern number is input (S36), a scaling factor is input (S37), and a specific point is input (S38). To enter the picture number, perform the operations "picture number", "1", and "TAB" (picture number 1
in the case of). In addition, the variable magnification input is "variable magnification", "1",
Operate with "2", "0", and "TAB" (when the magnification is 120%). Then, the specific point input indicates a predetermined point on the designated allocation sheet RS after the "specific point".

The pattern number is the same as the original document No. input in step S5 of FIG. 3, and the input of the variable magnification is omitted when the magnification measurement in step S6 of FIG. 3 is performed.

If the screen is shaded, enter the color of the screen (S3
9). This is "meshuse", "C", "1", "0", "T"
Perform "AB", "Y", "2", "0", "TAB" (C10
%, Y20%).

After this, it is judged whether or not there is a live ruled line (frames such as patterns) (S4
0) If there is a live rule, enter the color of the live rule (S4
1). This is "live ruled color", "M", "5", "0",
Do it with "TAB" (in the case of living ruled color M50%).

Following this, the "terminator" is designated (S42) to return to the flow repetition point. Then, the above-described operation can be performed on the new figure unless the "end" is instructed. When the "end" is instructed, the data input in step S2 in FIG. 3 is finished.

The data thus input are all recorded on the floppy disk FD of the original sticking sheet preparation apparatus A shown in FIG. 1 in step S3 of FIG.

Needless to say, the arrangement order of the steps in the flowchart shown in FIG. 6 is an example, and the order can be changed.

Further, the data input operation performed using the data tablet 9 is performed only for the plate surface coordinate input in step S31, the graphic input in step S34, and the specific point input in step S38 shown in FIG. 6, and other operations are dedicated. Simple input device,
For example, a personal computer may be used. In inputting various layout data using the dedicated input device, first, the position data input by the data tablet 9 and recorded in the floppy disk FD is given to the dedicated input device and displayed on the display provided. To be done. This display is performed for each layout frame graphic drawn on the designated layout paper RS. Then, for each frame graphic, data such as a plate color, a pattern number, a scaling factor (it is not necessary to input if input in step S6 in FIG. 3), a shaded color, and a live ruled color. Is entered. Then, these input data are recorded on the floppy disk FD and given to the layout apparatus B.

In this way, various layout data are input by the dedicated input device because many of the various layout data are not position data, and data other than these position data are input by operating the data tablet 9. than,
This is because it is more efficient to input with a dedicated input device. Further, it goes without saying that the original sticking sheet creating apparatus can be efficiently used by using the dedicated input device.

FIG. 7 is an explanatory diagram of input points on the data tablet 9 in step S7 of FIG. In the figure, a layout designation paper RS is placed on a data tablet 9 provided on the workbench 2, and a plate surface line H forming a rectangle and a layout designation graphic E are drawn on the layout designation paper RS. There is. The projected image I is projected so as to match the figure E.

First, the two points P on the printing plate line H drawn on the designated layout paper RS.
Input the position data of 1 and P2 with the cursor 11. This plate surface line H corresponds to a reference line when a document is attached to the input drum of the scanner. Next, the position data of the vertices R1, R2, R3, R4 of the rectangle forming the projected image I
The position data of the vertices Q1, Q2, Q3, Q4 of the rectangle indicating the trimming range in the projected image I is input with the cursor 11. These position data are used for the magnification measuring machine 1.
It is taken into the CPU 14 by operating the operation switch (not shown) or the keyboard 21.

FIG. 8 is an explanatory diagram showing the positional relationship of each point input from the data tablet 9 in step S7 of FIG. 3, and based on the figure, calculation of the sticking line data and trimming range data of the document in step S8 Will be described in detail.

When the coordinates of two points P1 and P2 on the printing plate line H in the XY coordinates shown in the figure are P1 (a, b) and P2 (c, d), the inclination θ of the printing plate line H with respect to the coordinate axis X is Becomes

Here, if the origin is PO (w, z), and the new coordinates with the plate surface line H and the line orthogonal thereto as the coordinate axes are xy, then X
The coordinate conversion formula from the −Y coordinate to the xy coordinate is as follows.

X = x cos θ + y sin θ + w Y = −x sin θ + y cos θ + z Becomes

Also, from the formula, sin θ and cos θ are Therefore, the coordinates of an arbitrary point input by the XY coordinates on the data tablet 9 are replaced with the coordinate values on the xy coordinates with the plate surface line H as a reference from the formula. For example, the dot
The XY coordinate value of R1 is (XR1, YR1), and the xy coordinate value is (xR
1, yR1) Becomes Similarly, all points of R2-R4 and Q1-Q4 are x-
It will be obtained in the y coordinate.

Next, drawing coordinate values for drawing with the XY plotter 17 are calculated from these coordinate values.

The magnification obtained in the magnification measurement work is m times, the coordinate axis obtained as a result of the above calculation is (x, y), and the drawing coordinate value is (Dx,
Dy) Becomes

Therefore, the drawing coordinate value drawn by the XY plotter 17 can be obtained from the equation.

FIGS. 9, 10, and 11 show examples of output position data input in step S9 of FIG. 3, and each example will be described with reference to the drawings.

FIG. 9 shows an example of displaying the original sticking line and the trimming line on the display 15 and inputting the output position.

FIGS. 19, 20 and 21 (a) to (g) are flow charts showing the data processing contents by the layout computer 29, and the positioning of the image data taken in the fixed disk 28 by this data processing is performed. Done.
The processing contents of the layout computer 29 will be described in detail below with reference to FIGS. 19 to 21.

First, the operator specifies the number of the image to be positioned using the keyboard 30 with display (S51). Next, the image of the designated number is entirely displayed on the display 32 (S52). Since the disk number in which the image is stored when it is input from the scanner unit 20 is recorded in the floppy disk FD, the desired image can be searched out by relying on it. Further, the thinning rate is calculated for displaying the entire image on the display 32. Here, since various modes are displayed on the screen of the display 32,
These various modes are selected by operating the mouse 31.

FIG. 20 shows the modes that can be selected with the mouse 31 in the form of graphics, and the modes of M1 to M7 corresponding to the graphics are menus with the following contents.

M1: Menu for instructing a specific point on the display 32 M2: Menu for instructing the range to be displayed without thinning out and displaying the divided area M3: For measuring the dot percentage of the point instructed on the display 32 Menu M4: Menu for allocating points designated on the display 32 to measure the coordinates on the designated paper RS M5: Menu for returning the split image to the whole image M6: Display of the currently displayed image Menu to end and move processing to the image of the next document number M7: Menu to end displaying the currently displayed image, processing moves to the keyboard with display 30 side. Mode M1 is set to enable the instruction of (S53). Then, in step S52, it is determined whether or not the positioning of the image displayed on the display 32 is completed (S54). This judgment is made by looking at the flag in the floppy disk FD. When the positioning is completed, that is, when the specific point instruction on the display 32 is completed, the trimming range of the image on the display 32 is calculated based on this specific point (S55). If the positioning is not completed, the trimming range of the image on the display 32 is calculated so as to be in the middle of the displayed entire image, and the specific point is calculated based on the calculated trimming range (S56).

When the specific points and the trimming range are determined in this way, these are displayed on the display 32 so as to be superimposed on the entire image (S57). Then, in this state, the input from the mouse 31 is awaited (S58).

Input by the mouse 31 is performed by designating a point on the screen of the display 32. If the designation of the mouse 31 is within the image area, it means that the specific point moving mode has been set (S59), and the designation of the mouse 31 is made. If is a menu area outside the image area, one of the modes M2 to M7 is set.

21 (a) to 21 (g) are flowcharts showing the processing contents of the modes M2 to M7, and the processing contents of the respective modes will be described below with reference to the drawings.

FIG. 21 (a) shows the specific point moving mode in step S59. In this case, when a point in the display image is designated with the mouse 31, the designated point becomes a new specific point, and the specific point has moved on the display 32 (S6
0). Then, a new trimming range is calculated based on this new specific point (S61), and the process returns to step S57.

FIG. 21 (b) shows a split display menu in mode M2. First, the mouse 31 is operated to indicate the center point of the portion to be displayed in the entire image (S71). The image to be displayed is an image that is not thinned out, and the instruction can be given up to three points. As a result, four points in the maximum image including the specific points are designated. Then, the image is divided and displayed on the display 32 centering on the point designated as the specific point (S72). This image is displayed without decimating each quadrant on the display 32.

Next, the specific point and trimming range on the divided display 32 are calculated (S73). Then, the specific point and the trimming range obtained by this calculation are displayed in an overlapping manner on the images divided and displayed in step S72 (S
74). After this, the M1 mode is set in preparation for the specific point instruction (S75), and the mouse 31 waits for input (S7).
6).

If the mouse 31 is in the image area, the specific point moves on the display 32 (S77), a new trimming range is calculated (S78), and the process returns to step S74. On the other hand, if the instruction of the mouse 31 is the mode M3 to M7 outside the image area, the instructed mode is set.

FIG. 21 (c) shows a menu for measuring the dot percentage in mode M3. When this mode M3 is instructed by the operation of the mouse 31, first, it enters a state of waiting for the coordinate input from the mouse 31 (S81). If the coordinates input from the mouse 31 are within the image, C, M,
The halftone% of each color of Y and K is displayed (S82), and the process returns to step S81. The displayed mesh% is the average value of the values of the pixels (for example, 9 pixels) in the vicinity of the point designated by the mouse 31 as the center.

On the other hand, when the mode M1 for instructing a specific point is designated by the mouse 31 in step S81, step S58 or FIG. 21 in FIG. 19 is selected depending on whether the image display state at this time is the whole display or the split display. The process moves to step S76 in (b) (S83) and waits for an input from the mouse 31. Further, in step S81, the menu for performing the split display in mode M2 is effective only when the full display is performed, and the menu for returning to the overall image in mode M5 is only performed when the split display is performed. It goes without saying that it is effective.

FIG. 21 (d) shows a menu for measuring the coordinates on the designated allocation paper RS of the point designated on the mode M4, that is, the display 32. When this mode M4 is instructed by the operation of the mouse 31, first, it enters a state of waiting for an input from the mouse 31 (S91). If the coordinates input from the mouse 31 are within the image, the coordinate value of the point designated by the mouse 31 on the layout designation paper RS is displayed (S92), and step S91
Return to.

FIG. 22 is an explanatory diagram showing an example of calculating the coordinate values on the layout-designating sheet RS in step S92, and points indicated by the mouse 31 are represented by PM. In the figure, the coordinates on the image data corresponding to the specific point P _s (xp, yp) are steps 51 to S61 in FIGS. 19 and 21 (a), and further steps S71 to S78 in FIG. 21 (b). It has already become clear as a result of the positioning by. Therefore, the coordinate value (xm, ym) of the point PM on the designated layout paper RS is calculated based on the coordinate value of the specific point PS, and the result is displayed on the display 32.

On the other hand, when the mode M1 for instructing a specific point is designated from the mouse 31 in step S91, step S58 or FIG. 21 in FIG. 19 is selected depending on whether the image display state at this time is the whole display or the split display. The process moves to step S76 in (b) (S93) and waits for an input from the mouse 31. Further, in step S91, the menu for performing the split display in mode M2 is effective only when the full display is performed, and the menu for returning to the overall image in mode M5 is only available when the split display is performed. It goes without saying that it is effective.

FIG. 21 (e) shows a menu for returning the image displayed in the mode M5, that is, the divided display to the whole image. When the mode M5 is instructed by the operation of the mouse 31, the divided display screen is displayed. The whole display is returned (S101), the M1 mode is set in preparation for the specific point instruction (S102), and the process returns to step S57 in FIG.

FIG. 21 (f) shows a mode M6, that is, a menu for ending the currently displayed image and shifting the processing to the image of the next document number, and when the operation of the mouse 31 instructs the mode M6. , The number next to the number of the currently displayed document is searched from the information in the floppy disk FD and set as the number of the next positioning image (S111), and step S5 in FIG.
Return to 2.

FIG. 21 (g) shows a menu for ending the image currently displayed in mode M7. When the mode M7 is instructed by operating the mouse 31, the layout work of the image currently displayed is performed. Then, the processing of the layout computer 29 shifts to the display-equipped keyboard 30 side.

When trimming, that is, positioning of the image data captured in this way is completed, the layout computer
The numeral 29 processes the data such as the plate color, halftone dot, and live ruled color recorded on the floppy disk FD. The processed data is stored in the fixed disk 28 again, and then output to the output drum 22 of the scanner 20 via the input / output computer 27 and the interface 26, and the film exposure is performed to perform Y, M, C. , K film originals will be created.

(Effects of the Invention) As described above, in the present invention, layout data including a trimming range instructed by the layout-designating sheet is input at the time of measuring the magnification of the original, and arithmetic processing is performed using the magnification data and the layout data to perform trimming. A document sticking sheet is created in which a range and a document sticking line forming a predetermined angle with respect to the trimming range are drawn, and layout data including magnification data and a trimming range is recorded on a recording medium. Further, the print data is given to the layout computer via this print medium, and the image data of the original input from the input drum using the original sticking sheet is displayed on the display together with the trimming range. Further, in the layout computer, the displayed image is laid out according to the instruction from the coordinate designating means, and the laid out image data is given to the output drum.
