DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prepress printing method,
For more details, please refer to the product
The present invention relates to a plate printing method and a plate printing apparatus using the same. [0002] 2. Description of the Related Art A stencil printing apparatus is one of the printing apparatuses.
You. This printing apparatus uses a punching process equivalent to a plate making process.
A stencil master with holes corresponding to the original image
It is wound around a plate cylinder with an ink transmission structure and installed inside the plate cylinder.
Ink from the ink supply mechanism
Transfer ink to printing paper pressed against
The image is printed more. [0003] By the way, one of the printing methods is a color photograph or a PO.
Using full-color originals such as stars,
There is multicolor printing. When performing this printing, color matching etc.
Fine adjustment, etc., HighAbove-mentioned technology is required.
With such a stencil printing machine, it was almost impossible. [0004] In recent years, drum replacement has led to full color
However, a stencil printing machine capable of multi-color overprinting is provided.
Came to be plannedEnemyAnd multicolor printing of 2-5 colors
It is becoming possible to be done. In particular, among multicolor printing, two-color printing is a manual operation.
It is considered to be frequently used because it is light. As an example of performing the two-color printing, a drum exchange
To print each color print image individually.
You. To explain this casenextIt is on the street. Manuscript reading
Color CCD or monochrome CCD
And place a color filter on the front to scan the original.
Sometimes color separation of each color is performed and the image information is stored in the control unit
Keep it. The first of the color image information stored in the control unit
For using the color based on the image information of the color
ToMadeA plate making process for making a print is performed. After plate making, plate making
The stencil mass perforated according to the image information
Rolled on the plate cylinder, and the color corresponding to the first color
KiIs supplied to the stencil master,
Will be Then wait for the first color image to dry
Image information of a second color of the colors separated by the color separation
The information is stored in the control unit. Stored in the control unit
According to the image information of the second color, the image is printed in the same manner as when printing the color.
The prepress process of the image master is executed,HoleEdition master
Different from the plate cylinder on which the stencil master of the first color is wound
And then supply the ink to the first
Printing on the same printing paper.
(For example, JP-A-64-18682).
As a method of forming the masters of different colors, for example,
For example, it is described in JP-A-48-46410.
A copy is formed using an electrophotographic process
The copy is printed with a fixing device and an etching device.
Method of forming as starThere is. [0007] However, as described above,
Such a multicolor printing method has the following problems. [0008] First, it is necessary to prepare plate cylinders for each color to be printed.
Need to increase the number of parts and maintain
become. The reason for using multiple plate cylinders is that the same plate
When using different color inks on the cylinderAriseColor mixing and use
Elimination of ink of the color usedAvoid operationsBecause
You. Second, when printing is performed for each color, multi-color printing is performed.
The required printing time is lengthenedFearis there. Printing time
Lengthening of the printed image after the first printing is completed.
DrynessButIt is also increased by the need. Replacing the plate cylinder
Work is required, printing worksexIs bad. This is the print
It is necessary to change the plate cylinder according to the number of colors
So, as the number of colors increases, the replacement work becomes more troublesome
In addition, the working time is also lengthened. Executed after plate cylinder replacement
When printing the next color, the printing position of the image
Consistency is likely to be poor, and the position as processing for this
Matching is required. Alignment requires a large number of colors to be printed.
It is done by the work of proof printing as it becomes more and more
Therefore, the workability of printing work will be
become worse. An object of the present invention is to provide a conventional multicolor printing method.
In terms of parts count and parts management
Work is possiblesexPrinting can also be improved
In providing a method and a printing apparatus using the same,
You. [0010] SUMMARY OF THE INVENTION In order to achieve this object,
