Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for creating a document pasting sheet for a scanner, which is used when performing color separation of various documents using a layout scanner.

(Technical background) In recent years, along with the color separation of originals using scanners, printed matter 1
Layout scanners that synthesize pages of image data through combinator processing are used in the field of printing plate making.

This layout scanner is a scanner connected to a computer with a page editing function, and image data captured by the scanner is fed to the computer, and after processing such as layout, is output to the scanner. When performing color separation work on a document using a scanner, it is first necessary to attach the document to the scanning drum of the scanner at the angle specified on the layout specification sheet, and then manually adjust the magnification and rimming range. be.

Conventionally, pasting of the above-mentioned original is done by an operator, and input of the magnification ratio and trimming range is done based on visual estimation. In other words, when pasting the manuscript, the angle of inclination of the figure drawn on the designated layout paper is measured with a protractor, and based on this measurement, the angle of the manuscript is confirmed using a protractor, etc. It is attached to the scanning drum. Regarding the magnification ratio, measure the distance ^11 between the two points of the figure drawn on the designated layout paper and the distance between the two points of the document corresponding to these two points with a ruler, etc., and calculate the ratio of the two measured values. Calculations are made to find the magnification ratio and then manually applied to the scanner. Regarding the trimming range, the operator manually inputs the trimming range into the scanner by visually measuring the trimming range while comparing the trimming range marked on the designated layout sheet with the document.

In addition, as an improvement to the work described in -■2, a device for measuring the variable magnification and measuring the angle of the original by using a magnification measuring machine with a function of projecting the original was disclosed in Japanese Patent Application No. 59-162108. It was proposed by Kideto Kide as an invention of the number.

However, the device that outputs the angle gauge of the document described above cannot specify the trimming range, and the actual situation is that the trimming range depends on the operator's visual estimation. Therefore, the image range captured by the scanner according to the operator's instructions often deviates from the actually required image range, and if the range captured by the scanner is smaller than the required range, it will have to be redone, and if it is larger, it will be a waste of capture time. Therefore, in any case, there was a problem that the scanner could not be operated efficiently.

Furthermore, with this Toyana, the diameter of the disassembly drum to which the original is attached changes in several stages depending on the disassembly magnification of the original, and each drum is not used when attaching the original to the disassembly drum, but also uses a document pasting sheet. needed to be created. Therefore, when creating the above-mentioned manuscript pasting sort, the manuscripts that can be pasted onto disassembly drums of the same size are selected in advance, and a manuscript pasting sheet is created that performs group pasting for the selected manuscript group. . This task of selecting manuscripts is performed based on the measured magnification value, which creates a problem that the task is complicated.

FIG. 10 is a schematic diagram showing the configuration of a -m layout scanner. In the leap, the layout scanner is a disassembly drum 51. Exposure drum 52, scanning head 53, control 1ff

0, it consists of a digitizer 61. Next, the creation of the laid out color separation file J that is sent to this layout scanner will be explained. First, the decomposition drum 51
The color source IF is turned on at 7:1, and the image light F is taken into the control section 54 from the scanning head 53 to the source 11 while rotating the decomposition driver 1 and 51. After the image light taken into the control unit 54 is spectrally separated, it is converted into R, G, and 3' hypochondriacal signals. , rKJ), and after various signal processing is performed, it is sent to the magnetic disk device 5H and stored as image data in a magnetic disk back (not shown) set in the magnetic disk device 58. be done.

This image data writing tα is performed for all documents used on the same page. Next, the 65I disk bag containing the image data is set in the magnetic disk device 59.

A layout designation sheet (not shown) showing the layout of one page is set in the digitalizer 61, and the position data of the stopper shape etc. drawn on this layout designation sheet is set. The computer 60 inputs layout data from the digitizer 61 to the computer 60 and layouts the image data stored in the magnetic disk drive 59 based on the layout data. This laid out image data is stored as page data in a hard disk (not shown) set in the magnetic disk device 62. Then, the magnetic disk puncture in which the page data is stored is set in the magnetic disk device 58 again. The control unit 54 is an IF disk device 58.
The above page data is read from Y, M.
, CSK are applied to the modulator for each signal.

On the other hand, an exposure film P is wound around the exposure drum 52, and is exposed to light from a light source 56. The intensity of the light irradiated onto the exposure film P from the light rA 56 is controlled by a light modulator 57, and the light modulator 57 is controlled by a modulator 55.

Therefore, the intensity of the light irradiated from the light [56 to the exposed film P changes in accordance with the changes in the Y, M, and C signals applied to the modulator 55, and the exposed film P
, M, C, are formed, and a color separation film of the laid out images is created.

By the way, since the decomposition drum 51 has a different drum diameter depending on the decomposition magnification, the document pasting sheet used when pasting the document on the decomposition drum 51 also needs to be prepared for each drum having a different diameter. Therefore, as a preparatory work before pasting the originals in this manuscript pasting sort, it is necessary to select the originals that use drums of the same diameter and decide on the disassembly order, which is very complicated. Therefore, it takes a long time, and as a result, the layout scanner cannot be operated efficiently, and furthermore, the workload of the preparatory worker is extremely heavy.

(Object of the Invention) The present invention has been made in view of the above-mentioned problems, and the present invention uses a separation drum that uses the pasting lines and trimming range of a document when measuring the magnification of the document prior to the color separation work of a layout scanner. To provide a device for efficiently operating a layout scanner by setting originals on a separation drum by outputting them separately and in the order of color separation (Summary of the Invention) To achieve this object, the present invention The system includes a magnification measuring device that measures the magnification of the original by projecting the original into a specified size, a digitizer that inputs the base line and pattern position data on the specified layout paper, and a magnification range for each separation drum of the scanner. and a storage device storing size data of the original pasting sheet;
Calculations are performed based on the magnification data from the magnification measuring device and the position data from the digitizer to calculate data on the document pasting line and trimming range, and at the same time, the scanner data is read from the storage device and is applied to multiple documents. an arithmetic control device that selects data on the original pasting line and trimming range according to the disassembly drum of the scanner; An apparatus for creating a document pasting sheet for a scanner is provided, which includes an output device that outputs the output in the order of color separation.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view showing an example of the apparatus for creating a document pasting sheet for a scanner according to the present invention. In FIG.
5 is a document holder, 6 is a lamp house, IO is a magnification display, 11 is a digitizer, 12 is a cursor, 13 is a menu, 20 is a computer, 21 is a keyboard, 30 is an X
The Y block is connected to a combination node 20 consisting of a main body 22 having a display. Note that F is a document, B is a designated layout sheet, and 1 is a projected image of the document F set on the document boulder 5.

A holder holding member 7 for setting the document holder 5 is provided at the bottom of the lamp house 6, and further below the holder holding member 7, a projection lens 4 fixedly supported by a support member 9 is arranged, and the holder holding member 7 and the support member 9 The space between them is covered with a bellows-shaped protective cover 8. The lamp house 6 and the support member 9 are movably supported by the support column 3, and form a fixed magnification of 14111 with the surface of the workbench 2 as the projection plane. Digitide 11 is buried in the surface of workbench 2,
On the surface of the digitizer 11, a split (・1 designation) B is set. Therefore, the document F mounted on the document holder 5 is sent from a light source provided in the lamp house 6 to an appropriate condenser lens. illuminated through etc.
A projected image 1 of the picture is projected onto the surface of the layout designation sheet B.

Since the projection lens 4, document holder 5, and lamp house 6 are movable up and down along the column 3,
@Measurement By operating the switch on the operation control panel (illustrated, humming), etc., the image of the original F is moved downward to -E, thereby reducing or enlarging the image of the document F to an arbitrary size over a predetermined range. I can be imaged on the surface of the designated layout paper 13, and by capturing the distance ^1 (between the projection lens 4 and the designated layout paper B at this time with a linear encoder etc. and processing the expression 1γ), (u :rf- is calculated, and the value is displayed on the magnification display 10.

Therefore, the original F is placed on the original holder 5 seven times, and the projected image l is one? If you set the designated paper B with 1 (1δ is written and type 1), the magnification will be automatically displayed on the magnification display lO, and you can finish the magnification measurement.
Such automatic magnification measuring machines are well known.

FIG. 2 is a block diagram showing an example of a signal processing system in the apparatus shown in FIG. tllγ at this time:h control unit 22
The import of data and the start of /'A arithmetic processing can be controlled by pointing the cursor 12 at a predetermined position on the menu 13 or by using the keyboard 21 installed in the computer 20. ff1l, and a drive signal is output to the XY plotter 30.

Figure 3 shows an example of menu 13. Menu 1
3 is provided with a numeric keypad 35, a scanner designation command 36, and various manual commands 37.

"Manuscript floor" in the input command 37 is a command to input the manuscript, "magnification" is a command to input the magnification value displayed on the magnification display 10, and "process" is a command to input the document pasting line and trimming range for each disassembly drum, and The arithmetic processing commands for outputting in color separation order are: "Cj is clear,""input" is enter, and "output" is the output command of the XY plotter 30.

Figure 4 shows 1. ! An example of specification data for each scanner stored in the VZ 23 is shown. In the figure, a magnification 41, a disassembly drum 42, and a document pasting sheet size 43 are set as specification data items. Decomposition Dragon J,
42 is standard, and in this embodiment, three types, large, medium, and small, and two types, dog and small, are set. The magnification 41 indicates the decomposition magnification/de range to which the drum of the type shown in the decomposition drum 42 is applied, and the document pasting sheet size 43 indicates the extent to which the document pasting sheet size 43 is applied to the drum of the type tn, which is not shown in the decomposition drum 42. Indicates the size of the notebook.

The reason why the 411 angle of the ram is the stomach is as follows. This is because the image capture speed of the scano' differs depending on the magnification, and this speed adjustment is performed by changing the circumferential speed of the drum by changing the drum diameter. It is assumed that such specification data for each scanner is stored in the storage device 23 in advance.

Next, the operation will be explained.

First, the document holder 5 on which the document F is set is stored in the holder holding member 7, and then the layout designation paper B is placed at a predetermined position on the workbench 2 in which the digitizer 11 is embedded.

Next, the image of the original F is split (;j) and projected onto the designated paper Bl-,
A switch on the tffl panel (not shown) of the magnification measuring device 1 is operated to match the projection image 1 of the original F with the stopper shape drawn on the layout designation sheet B. At this time, the magnification value of the document F is displayed on the magnification display 10.

FIG. 5 is a flowchart showing the processing in the arithmetic and control unit 22.

First, the target scanner model is input using the scanner specification command 36 in the menu 13 provided on the digitizer 11 (Sl), and the specification data shown in FIG. 4 is read out. Next, using the various input commands 37 of the menu 13 and the numeric keypad 35, the magnification value displayed on the document side and magnification display of the document F is input with the cursor 12 (S2). Various positional data on paper B are input.

FIG. 6 is an explanatory diagram of human effort points on the digitizer 11. In the figure, a digitizer 11 installed on a workbench 2
Layout designation paper B is placed on top of the layout designation paper B, and on the layout designation paper B there are plate surface lines [I and a stopper type El for layout designation] forming a rectangle.
E2 and E3 are drawn. The projected image I is projected to match the plug shape El.

First, use the cursor 12 to manually enter the coordinate values of two points I'l and P2 on the printing surface H drawn on the layout designation sheet B (S
3). This printing plate line H corresponds to a reference line when pasting a document onto a disassembly drum of a scanner. Next, use the cursor 12 to input the coordinate values of the vertices R1, R2, R3, and R4 of the rectangle forming the projected image
Manually input the coordinate values of vertex Ql, Q2.03, and mouth 4 of i1 using the cursor 12 (S5). Also, if the stopper type E1 on the layout designation sheet B is not rectangular, for example, it is circular like the stopper type E3. In this case, it is sufficient to set a circumscribed rectangle G shown by a broken line and input the coordinate values of its four vertices. These coordinate values are taken into the arithmetic control unit 22 as position data by inputting the commands in the various commands 37 of the menu 13.

In this way, when the position data on the layout designation sheet B is input manually,
At this point, the arithmetic control section 22 starts processing the position data and the magnification value data, calculates pasting line data and trimming range data of the document F (S6), and further determines the decomposition drum (S7). The processes from step 2 to step 7 are performed on a series of a plurality of documents.

After this, in the various input commands 37 of the menu 13,
When the "Processing" command is input, the documents that can be input using the same disassembly drum are collected, a group is formed for each disassembly drum for the plurality of documents, and the pasting position on the document pasting sheet is determined for each group. is determined, and thereby the decomposition order is determined (S8). Next, when the "output" command in the various manual commands 37 of the menu 13 is input, the XY plotter 30 starts the graphic output operation, and displays the document pasting line and trimming range for each group formed in step 8. The hard copy with the figure drawn is completed (S9).

FIG. 7 is a diagram showing the positional relationship of the points on the digitizer 11, and the calculation of the document pasting line and trimming range data in step 6 will be explained in detail based on the diagram.

Two points 1'L on the printing plate line 11 in the X-Y coordinates (not shown in the figure)
When the coordinates of R2 are PI (a, b), P2Cc, d), the head θ of the printing plate cotton 11 with respect to the coordinate axis X is −bLanθ=□■.

Here, if the origin is PO (w, z) and the new coordinates whose coordinate axes are the plane line H and the line orthogonal to this are X-y, the coordinate conversion formula from the X-Y coordinate to the x-y coordinate is It will look like this:

X=XCO3θ+y sinθ+W y=-xsinθ+ycosθ+2 Than this becomes.

Also, from equation 0, sin θ and CO30 are expressed as will be replaced with the coordinate values of For example, the x-y coordinate values of point R1 are (XR1, YRI), x - y
p8! Let the i standard value be (xRl, yRI). Similarly, all tons of R2-R4 and Ql~04 are obtained in xy coordinates.

Next, drawing coordinate values for drawing with the XY profiler 30 are calculated from these coordinate values.

The magnification obtained in the magnification measurement work is multiplied by m, and the coordinate values obtained as a result of the above calculation are (X, y), lAt ii! i
If the Il $ target value is (Dx, Dy), then

Therefore, the drawing coordinate values to be drawn by the XY plotter 30 can be obtained from equations (1), (2), and 0.

Calculation of the output size is based on the two adjacent sides (lIQ2
．． It can be obtained by calculating the length of 01 mouth 4. Here, the length of the side is 02, and the length of QIQ4 is 2.0.

FIG. 8+a+, (bl is an explanatory diagram showing an example of the output of the XY plotter 30 in step 9, and in the same figure (al is an example of drawing on an opaque notebook 100 such as paper. In the figure, a transparent sheet) 100. At the top, there is a base [￥
Cotton 101 is drawn 114 times, and the scanner model 10 is displayed on the upper left.
05, the decomposition drum 100F to be used is drawn.

Further, a rectangular original pasting line 102 is drawn in the center of the transparent sheet 100, and a trimming line +03 indicating a trimming range is drawn inside the original pasting line 102, but this trimming line +03 is a rectangular shape. is drawn with each side extended to the outside of the original pasting line 102. This is because the blank note 100 is cut and cut out along the original pasting vA102, and then the original is set in the cough cutout section. Also, the output 1'h is placed above the original pasting line.
100a, original 1'hloON, magnification value 100m, and resolution size 100z are drawn, where X of the resolution size 10oz is the size of the output horn image in the drum axis direction, and Y is the 4J size of the output image in the drum circumferential direction.

FIG. 8 fbl is an example of drawing in transparent sort 200.

In this case, unlike the opaque sheet 100, the trimming line 2 is not cut along the original pasting line.
03 is drawn in the original pasting line 202 (11) in a rectangular shape.

In this way, each document's data is stored in the same decomposition drum.
The manuscript pasting note with the manuscript pasting lines and trimming lines drawn is handed to the scanner operator together with the manuscript. By simply pasting the original on this original pasting sheet, the scanner operator can manually manually feed originals that use the same disassembly drum into the magnetic disk drive 58 shown in FIG. 10 in an accurately trimmed state. .

FIG. 9 shows an example in which the image data stored in the 6ft disk device 5B is page-edited by the computer 60 shown in FIG. 1O, and then outputted onto exposed film.

In the figure, images 301, 302, and 303 have a magnification of 200
%, so they were created manually using the large drum of Hess Toyana shown in Figure 4, and images 304 and 305 are not shown in Figure 4 because their magnification is in the range of 201 to 600%, and were created using the Δ scanner. The middle drum was made by hand. As shown in the figure, the computer 60 outputs Y, M, and C decomposed images in two columns each in the vertical and horizontal directions for the image data that has been converted into page k[4. In this way, the manuscripts are collected for each disassembly drive and a manuscript pasting note that can be pasted is automatically output, thereby eliminating the need for cumbersome manuscript selection work.

(9. Effect of brightness) As described above, in the present invention, by providing a digitizer in the magnification measuring device and storing the scanner specification data in advance in the computer, the original color separation work performed by the scanner is performed. When measuring the magnification, by simply inputting the position data on the designated layout paper, the original pasting line and the trimming line indicating the trimming range are simultaneously drawn for each separation drum of the scanner in the order of color separation, and the original pasting sheet is easily created. This greatly improves the efficiency of pasting documents onto the scanner's disassembly drum, and allows accurate setting of the trimming range, which was conventionally dependent on the operator's experience and knowledge and was prone to mistakes. In addition, since it outputs a manuscript pasting sheet on which manuscripts can be collectively pasted for each disassembly drum used, tasks such as selecting manuscripts and determining the disassembly order, which are performed as preparatory work before pasting the manuscripts on the manuscript pasting sheet, are output. This is no longer necessary, and has the effect that the operating rate of the layout scanner can be greatly improved.
