Abstract

PURPOSE:To make it possible to arbitrarily convert the size of a proof manuscript, by converting the clock frequency on a scanning line when developed character data is read to be outputted to the main scanning direction of paper and outputting the same so as to thin out the arbitrary scanning line of character data when said data is outputted to a sub-scanning direction. CONSTITUTION:An arbitrary value is preset to a decoder and, every when the figure-up signal of an n-steppting counter is inputted, said arbitrary value is compared with the number of times of said signals. If both of them coincide as the result of comparison, an m-stepping counter 32 is stepped by one and a new Y-address is outputted. That is, operation for thinning out scanning line output in an arbitrary sub-scanning direction is performed. If M-numbers of values were set to the decoder 31, M-scanning lines are thinned out. A clock generator 23 receives a signal from CPU21 to transmits the same to an interface 24 while the interface 24 converts the character data read from bit map memory 22 in a bit unit to the clock frequency on a scanning line when the printer 3 performs output to the main scanning direction of the paper in a bit unit.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a printing method for a proofreading document for proofreading a printed matter of a computerized phototypesetting machine or the like.

[Technical background of the invention and its problems] When creating a printed matter with a computerized phototypesetting machine, exposure (printing)
The printed content cannot be checked unless the photosensitive material is developed. Therefore, the character data to be printed by a computerized phototypesetting machine is first input into a proofing terminal with a display screen, such as a CRT, and the contents of the character data are checked before printing, and then the desired printed matter is created by the computerized phototypesetting machine. This method is becoming common practice.

However, with this method, the author who does not have a proofreading terminal or the orderer cannot confirm the content, so approval cannot be obtained in the end. Therefore, as shown in FIG.
This printer is used to create proofread manuscripts and send them to the client for approval.

If this printer 3 is a normal raster set printer,
Regardless of the method, various types can be used, and a typical example of the computerized phototypesetting machine 1 is shown in FIG.
It is only necessary that the character data from the above are assembled into an arbitrary format by the character typesetting control section 5, and then printed on the roll-shaped long photosensitive material 8 by the output section 7 controlled by the output control section 6. In addition, the device for obtaining typed and processed character data is not limited to the computerized phototypesetting machine mentioned above, but any character processing device that can receive character signals and compose them into text can be used. Can be done. In this application, they are collectively referred to as a computerized phototypesetting machine.

Next, the relationship between the printing state on the photosensitive material 8 and the proofreading document 9 created by the printer 3 will be explained using FIG. 4. A in the figure shows a part of the roll-shaped photosensitive material 8 on which horizontal text is printed, and the area surrounded by the frame 10 is one page or one arbitrary block. Line 1 within frame 10
1 represents a sentence for convenience, but in reality this frame 10
When printing , many ``a'' will be printed.

As a pre-process for creating such a printed matter, a proof original 9 is created by the printer 3 as described above. The various printers currently on the market and in practical use are JIS △
Since each sheet of -4 or B-5 size is used, the proofreading manuscript will also be output on A-4 or B-5 size paper.

FIG. 4B shows a state in which an area of the same frame as the frame 10 indicated by A is printed on the paper 11 as the proofreading document 9. In this case, since the printing area 10 is smaller than the size of the paper 9, the text to be printed on the photosensitive material 8 can be output onto the paper 11 as the proofreading original 9.

However, a situation may often occur in which the area of the frame 10 exceeds the area of the paper 11 shown in B. For example, in FIG. 5A (a), the length direction of the paper 11 in (b) may be shorter by Pl than the length Ll of the photosensitive material frame. In this case, if a 10-minute area of the photosensitive material is printed on paper, it will be divided into two sheets and only the first line will be printed on the second sheet. Also, as in B (A), the width direction of the paper in (B) is P2 compared to 12 (B) may be shorter. In such cases, only the second sheet of paper is output. Therefore, only 1 This means that the user is forced to output one sheet of paper for each line, and the proofreading process becomes cumbersome as the user has to check two sheets.

[Object of the Invention] The present invention provides printing of a proofreading original in which the size of the proofreading original to be output on the paper 11 of the printer 3 can be arbitrarily converted so that printing can proceed even on paper of a fixed size. The aim is to provide a method.

As a result, the original for proofreading will be slightly different from the state actually printed on the photosensitive material, but the output of two sheets of paper will be
Since it can be combined into a single sheet, the purpose is to efficiently promote character proofreading and to reduce the amount of paper used as the output medium of the printer.

[Summary of the Invention] That is, the printing method of a proofreading original of the present invention includes: Expand character data to bitmap memory;
When reading this expanded character data and outputting it in the main scanning direction of paper, the clock frequency on the scanning line is converted, and when outputting it in the sub-scanning direction, arbitrary scanning lines of the character data are thinned out and output. The present invention is characterized in that the size of the original for proofreading is arbitrarily converted to the character data developed in the bitmap memory and outputted.

[Embodiments of the Invention] FIG. 1 is a configuration diagram showing an example of an apparatus suitable for carrying out the printing method of a proofreading original according to the present invention.

Character data processed by the computerized phototypesetting machine 1 is sent to the CPU 21 via the interface 20. CPU
Then, the encoded and compressed character data is restored and outputted via the memory controller 23 to the bitmap memory 22, which has one bit corresponding to one dot of the printer 3 and stores an arbitrary amount of character data. Memorize it as an image. The printer interface 24 reads data in bytes from the bitmap memory 22,
Transfer to printer 3 bit by bit.

Next, the operation will be explained using FIG. 6, which is a partially detailed diagram of FIG. 1. In the figure, 3o is an n-ary counter that can count the maximum coordinate value n in the X direction of the bitmap memory 22, and the counter l~ signal is sent via the memory controller 23 to the Specify them sequentially. When this n is counted by the counter 3o, a signal is sent to the decoder 31 and the m-ary counter 32. The m-ary counter is capable of counting the maximum coordinate value m in the Y direction of the bitmap memory, and specifies the Y address of the bitmap memory 22 via 23. m
After counting, the m-adic counter returns to 1.

An arbitrary value is set in advance in the decoder 31, and each time there is a carry signal n from the n-ary counter, the arbitrary value is compared with the number of times. If the comparison results match, m
The advance counter 32 is incremented by one and a new Y address signal is generated. That is, the scanning line output in an arbitrary sub-scanning direction is thinned out. If M values were set in the decoder 31, M scanning lines would be thinned out, and as a result, the original size AC of the area 10 represented by ABCD in FIG. 7 would be AC'' This means that the sub-scanning direction is reduced by P3 in the figure.

This state is shown in (c) of Figure 5B, where area 10
is reduced by P3 to become IOH, and the proofreading original 9 is output within this 10H.

A clock generator 33 receives a signal from the CPU 21 and transmits the clock to the printer interface 24.

Then, the interface 24 is connected to the bitmap memory 22.
The character data read in bytes from the printer 3
converts the clock frequency on the scanning line when outputting the paper bit by bit in the main scanning direction. That is, if the clock frequency on one scanning line is increased, the length of the scanning line reproduced by the printer will be correspondingly shortened. For example, if the clock speed is increased by N times, the original size of area 10, AB, in FIG. 7 becomes AB=. That is, the scanning direction is reduced by P4 in the figure. This state is shown in Figure 5A.
In (c), the area 10 is reduced by P4 to become IOV, and the composition original is output within this 10*.

The values of P3 and P4 shown in Figures 5 and 7 are set in advance by CPU2.
1, but the signal 35.1 shown in FIG.
36 can also be used. In other words, computerized phototypesetting machine 1

It is also possible to provide the signal 35 representing 0 and the signal 36 representing the paper size set in the printer 3 to the CPLI to automatically calculate the two, and use the results to determine the above-mentioned P3 and Pa.

[Effects of the Invention] As described above, the printing method of the proofreading original according to the present invention allows the size of the proofreading original to be arbitrarily converted and outputted, so even if the size of the proofreading original is outputted on two sheets, it can be combined into one sheet. This allows for efficient calibration work. In particular, the effect is further improved in the case of printed matter such as a person or a map, which would be extremely difficult to see if output in two parts. It is also possible to obtain the additional effect of reducing the amount of paper used.
