Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a multipass operation color plotter that serially outputs color drawings for each color by a host computer. The present invention relates to a control device for outputting.

[Conventional technology]

FIG. 6 shows a principle diagram of a color plotter of a multipass operation, in which a winding roller 1, a drive roller 2 and a paper feeding roller 3 are provided so as to be able to rotate in the normal or reverse direction, and the electrostatic recording paper 4 is reversed to these rollers. It is installed freely. Then, a cyan developing device 5, a magenta developing device 6, a black developing device 7 and a yellow developing device 8 are arranged on the drive roller 2 and the paper feeding roller 3 side, respectively, and a cyan toner liquid 9, a magenta toner liquid 10 and a black toner, respectively. Liquid 1
The developing solution is supplied from 1 and the yellow toner solution 12. In addition, the writing head 1 is provided on the side of the paper feed roller 3.
3 and a mark reading sensor 14 are provided.

Conventionally, in the above-mentioned color plotter, first, a tic mark serving as a reference for color matching is plotted, and an electrostatic latent image for each color is transferred to the electrostatic recording paper 4 by the writing head 13 based on this. Overwriting is done with black, cyan, magenta, yellow or cyan, magenta, and eiro pass. For example, in a 5-pass overwriting, as shown in FIG. 7 (f), when it is desired to plot + in a horizontal row for each color, when a command for specifying the plot length is received from the host side,
As shown in FIG. 7 (b), the ticks 15 are plotted at predetermined intervals on both sides of the electrostatic recording paper 4 by the plot length, rewinding is automatically performed, and then black is plotted ( c) Rewinding is automatically performed again, and cyan, magenta, and yellow are similarly plotted with reference to the tick mark 15 (d, e, f). It should be noted that in the method of plotting the tick mark and the black at the same time, the operation is four passes.

FIG. 4 shows a system configuration in which the above color plotter is incorporated into an online system. The multicolor plotter 20 is connected to a host computer 22 via a controller 21. The element data on the host side includes the input processing unit 23, the data conversion unit 24, and the sorting unit 2.
5. It is converted into raster data through the raster conversion unit 26 and output to the multi-color plotter 20 through the output processing unit.

When the same color drawing is output a plurality of times in the above system, the same data is copied a plurality of times on the host side, and each drawing data is output to the multi-color plotter 20 via the controller 21, and the method described in FIG. After multi-passing to obtain one drawing, it is output again to the multi-color plotter 20 via the controller 21 to obtain the next drawing. For example, when two identical color drawings are obtained, as shown in FIG. 5, the tick marks are discontinuous and the drawings A ₁ and A ₂ are output.

[Problems to be solved by the invention]

However, when outputting the same color drawing n times,
In the above conventional method, the system controller 2
The process in 1 is performed n times, and the multicolor plotter 2
In the case of 0, since the pass operation is performed 4 to 5 times as described above, there is a problem that processing is required 4 to 5 × n times in total and the processing time increases.

The present invention solves the above problem, and an object of the present invention is to provide a control device for a color plotter that can significantly reduce the processing time.

[Means for solving problems]

Therefore, the color plotter control device according to the present invention is configured as follows. That is, in a color plotter that outputs a plurality of identical color drawings online, including a color plotter that plots each color in a plurality of passes and a host computer that connects the color plotter through a controller The color data is stored in the raster data storage through the raster converter, while the tick mark length contained in the command for drawing the tick mark input from the host computer is multiplied by the number of output sheets and sent to the multipath color plotter. Then, after the data of one color accumulated in the raster data accumulating section is continuously output for the number of output sheets, the paper is rewound, and the above process is sequentially repeated for four colors.

[Action]

In the present invention, for example, when the same color drawing is output n times, as shown in FIG. 2, first, the tick mark length is multiplied by the number of output sheets to output n tick marks.
The paper is rewound, then the data of one color is output n times, the paper is rewound to plot the next color, and this is repeated until four colors are output.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram showing an embodiment of a color plotter control device of the present invention, FIG. 2 is a diagram for explaining a processing flow, and FIG. 3 is a diagram showing an output drawing.

In FIG. 1, one-color data input from the host computer 22 is stored in the raster data storage unit 30 via the input processing unit 23, the data conversion unit 24, the sorting unit 25, and the raster conversion unit 26. On the other hand, during this time, the tick mark length included in the command for drawing the tick mark input from the host computer 22 is multiplied by the number of output sheets, and the result is sent to the multipath color plotter 20. After continuously outputting the data of one color accumulated in the raster data accumulating unit 30 by the number of output sheets, the paper is rewound. The above process is repeated four times in sequence.

FIG. 2 shows the flow of processing when the same color drawing is output n times. First, in the step, after the number of output sheets is divided by the tick mark length to output the tick marks for n times, the paper is rewound (). Next, after outputting the data of one color n times (), in step, the paper is rewound to plot the next color as described in FIG. 6, and this is repeated until four colors are output ( ).

In the above embodiment, the paper rewinding is required 5 times in total, but if the data of one color is simultaneously output when the tick mark is output, the paper rewinding is 4 times.

FIG. 3 shows a case where the same color drawing is output twice, and shows that drawing A ₁ and drawing A ₂ are continuously output on a sheet having continuous tick marks. Therefore, according to the present invention, the multipass color plotter 20
In the prior art, the operation of (4) -5 times the number of output times can be performed, but it is possible to perform the operation in 4-5 times regardless of the number of output sheets.

[Effect of device]

As described above, according to the present invention, after the tick mark length is multiplied by the number of output sheets and output to the multipath color plotter, the data of one color accumulated in the raster data storage section is continuously output for the number of output sheets. , Rewind the paper,
Since the above process is repeated four colors in sequence, the time required for drawing can be greatly reduced.
