Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing data output device and method for a printing press, and more particularly, to a printing press that can easily output print data larger than the printing size of the printing press. The present invention relates to a data output device and a method thereof.

[0002]

2. Description of the Related Art Conventionally, an overwritten image formed by sequentially supplying multicolor liquid toners to a surface of a photosensitive drum that rotates at a constant rotation is transferred to a transfer roller and a backup roller via a transfer roller. Printing machines are known that transfer onto a printing sheet placed between them. This printing machine
A charging unit that charges the surface of the photoconductor drum to give it photosensitivity, an exposure unit that exposes and scans the photoconductor drum based on print data to draw an electrostatic latent image, and a static unit on the photoconductor drum. And a developing means for developing the latent image,
The developing unit includes a plurality of developing rollers that sequentially supply multicolor liquid toners to the photosensitive drum.

Among the printing presses described above, for example, A2
With a printing machine that can print up to the size of (vertical) size paper,
In some cases, it may be necessary to print print data that is larger than the A2 (vertical) size, for example, the B2 size. In such a case, conventionally, the operator first uses, for example, a DTP (desktop publishing) system that creates a publication or the like based on the print data using a small computer system such as a personal computer or a workstation. The print data of the size is divided into A2 size that can be printed by the printing machine, and the respective divided print data is output.

That is, as shown in FIG.
When the print data 60A of (vertical) size is sent, the print data 60 is divided into two parts up and down, and each is rotated 90 degrees counterclockwise. A2 (vertical) size print data 70
Is set to output 2 sheets. Also, FIG.
As shown in (B), when the print data 60B having a paper size of B2 (horizontal) size is sent, the print data 60B is divided into left and right, and A2 from the printing machine.
The print data 70 of (vertical) size is set to be output as two sheets. After being divided and set by the DTP, the print data is input to the RIP (raster image processor). This RIP outputs two pieces of A2 size print data 70, as described above, by the division setting.
Then, the printing machine prints the output A2 size print data 70.

[0005]

However, in the conventional method in which the operator divides and outputs the data, when the print data larger than the printable size is input by the printing machine, the operator uses the DTP system each time. Then, the large size print data must be divided into printable sizes. The printable size on the printing machine is
The size of the drawing (paper) specified by JIS, eg A2
If the input print data is in the (vertical) size and belongs to the A column, for example, A1 is a size obtained by combining two A2s in the vertical direction, so that it can be easily divided. The operator has to input the number of divisions into the DTP system and perform operations such as rotating by 90 degrees, which is troublesome and time consuming. Also, DTP
A person who is used to operating the system is required. Further, if the input print data belongs to a column B different from the column A, for example, B0 size, printable A2 size and B
Since there is a difference in size between the 0 size and the A column and the B column, the B column is larger than the B column even if it has the same size, so it cannot be easily divided. There is a problem that the processing takes a lot of time. In addition, if there is a difference in size between the two, there is a risk of inputting an incorrect division method and division number.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a division output device of a printing machine and a method thereof which can easily and surely divide and output even print data larger than a printable size.

[0007]

When the printable size is determined, the print data is output to the printing unit as it is.

According to the present invention as described above, when it is determined that the print data input from the print data input unit is larger than the printable size of the printing unit of the printing machine, the division control unit can print the print data. When the print data is divided into sizes and output, and the print data is determined to be a printable size, the print data is output as it is. Therefore, the operator can print the print data larger than the printable size by using the DTP system or the like. It is not necessary to output the data after dividing it into various sizes, and the division processing can be performed quickly and reliably.

In step 5, the exposure signal is converted into a signal (exposure signal) for driving the exposure device 4, and the exposure signal is transmitted to the exposure device 4 by a drive command signal issued from the process control unit 40 of the print data output device 30. It

When the process control unit 40 is created by the print data input unit 25 and the print data input from the print data input unit 25 is the printable paper size of the printing machine 1, the process control unit 40 outputs the print data as it is, and when the print data is larger than the printable size. , Is divided into printable paper sizes and is output to the printing unit 50. The process control unit 40 includes a size determination unit 41, a printable size storage unit 42, and a division control unit 43.

The size discriminating section 41 includes a print data input section 2

It has a function of determining whether the size is the following.
The printable size storage unit 42 has a function of storing the printable size of the printing unit 50 of the printing press 1. The division control unit 43 compares the size of the input print data with the printable size of the print unit 50, and the size determination unit 41 determines that the size of the input print data is larger than the printable size. In this case, print data larger than that size is optimally divided into printable sizes.

The division control unit 43 is provided with a table 45, and the table 45 has a correspondence table 4 as shown in FIG.
6 is provided. In the correspondence table 46, how to divide print data larger than the printable size of the print unit 50, for example, A2 size, that is, print data of A1, A0 and B2, B1, B0 size is preset. There is. Then, the division control unit 43 automatically selects a designated number for which the optimum division is determined for the input print data, and outputs a drive command signal to the exposure control unit 35 to divide the divided A2. The size is output sequentially.

As described above, since the B column is larger in the same size, when the printable size is A2, it cannot be accurately divided by A2, and a surplus portion occurs. Vertical B
Both 0 and horizontal B0 are optimally divided into A2 × 8. That is, the print data 70 of eight vertical A2 sizes is sequentially output. However,
Since (B) is a horizontal size, it is rotated 90 degrees counterclockwise, for example, so that it is output in a printable vertical A2 size.

Next, the operation of this embodiment will be described with reference to FIG. First, in step (hereinafter referred to as ST) 1,
When started, in ST2, the size determination unit 41 determines the size of the print data input to the process control unit 40. In ST3, it is determined whether the determined print data size can be printed by the printing unit 50 of the printing press 1.
If the printable size is, for example, A2 (vertical) or smaller, printing is performed on one sheet of printing paper in ST4. If the size of the print data determined in ST3 is not within the printable range, that is, if it is determined that the size is larger than the A2 size and printing cannot be performed as it is, the division control unit 43 of the process control unit 40 determines in ST5. From the correspondence table 46 entered in the table 45, the optimum division designation number for the judged print data is automatically selected, and in ST6, the originals divided by the printing unit 50 of the printing press 1 are sequentially printed, ST7
Press to finish printing.

(1) Whether or not the print data input from the print data input unit 25 is larger than the printable paper size in the print unit 50 of the printing press 1 and automatically printable by the size determination unit 41. If it is larger than the printable size, the division control unit 43 controls the division into the printable size and outputs it. Therefore, the operator uses the DTP system or the like to output the print data larger than the printable size. You don't have to output after dividing into printable size,
The operation for that is unnecessary, and the division processing can be performed quickly and reliably.

(2) In the division control unit 43, when the input print data is larger than the paper size that can be printed by the printing unit 50 of the printing press 1, the corresponding data is changed from the correspondence table 46 provided in the table 45 to that data. Since the optimum division number is selected and output, and the correspondence table 46 covers all sizes larger than the printable paper size,
No calculation is required, the response time is shortened, and the processing becomes faster.

The present invention is not limited to the above-mentioned embodiment, but may be modified as follows as long as the object of the present invention can be achieved. That is, in the above embodiment, when the paper size of the input print data is larger than the printable size in the printing unit 50, the division control unit 43 divides the print data based on the correspondence table 46 provided in the table 45. However, the present invention is not limited to this, and a calculation unit may be provided to perform calculation based on the vertical and horizontal dimensions to perform division. In this way, particularly when the paper size is out of the standard, optimum division can be easily performed.

Further, in the above-described embodiment, the printing machine 1 uses the printable paper size of A2 size, but the present invention is not limited to this, and the present invention is of a larger size or a smaller size. It can also be applied to a printing machine that prints sizes.
