Abstract

PROBLEM TO BE SOLVED: To conduct an operation of drawing lines and a center line in single- facing plate-makign, by an efficient, accurate and a simple method, corresponding to a PS plate having a large number of kinds of sizes. SOLUTION: This line-drawing machine is constituted of a drafting board 1 whereon positions of a PS plate guideline 8 and a center line 9 are shown, a parallel ruler 2 whereon a dimensional scale of the PS plate guideline is shown and a guide rail 3 whereon a dimensional scale of a margin of line is shown, and a stopper 6 for setting the position of a PS plate correctly is provided below the drafting board. According to this constitution, the PS plate can be positioned correctly by the stopper 6 and the PS plate guideline 8, and the line and the center line can be drawn correctly by the dimensional scale 10 for the margin of line shown on the guide rail 3 and by the scale shown on the parallel ruler 2.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a P
In addition to displaying the S version guidelines and the position of the center line,
A PS plate tongue that is composed of a parallel ruler that displays the dimensional scale of the S plate guideline, and a guide rail that displays the dimensional scale of the sill plate, and that is provided with a stopper below the drawing board to accurately determine the position of the PS plate. It is about the machine.

2. Description of the Related Art Hitherto, in a printing plate making process, an operation of accurately drawing a carving line or a center line on a PS plate has been performed. Usually, in the case of multi-face plate making, the process is computerized, and the work of attaching a mylar base (film) having a pin hole to a predetermined position is sufficient. On the other hand, in the case of one-side plate making, the work of making a pin hole in the mylar base (film) and mounting it becomes laborious and costly, so each time using a T rule or a triangle ruler,
The hand line and center line were drawn by hand.

[0003]

Since the PS plate used in the plate making process has various sizes, it was necessary to measure the carnation and the center each time and draw the carp line and the center line each time. . Since these are performed manually, technical skills are required and work efficiency is poor. For this reason, high skill is not required, and it corresponds to PS plates of various sizes,
Efficient and accurate drawing of the carp line and center line was required.

[0004]

The present invention comprises a drafting board on which the position of the PS plate guideline and the center line are displayed, a parallel ruler on which the dimensional scale of the PS plate guideline is displayed, and a guide rail on which the dimensional scale of the sill is displayed. A stopper for accurately determining the position of the PS plate was provided below the drawing board. With such a configuration, when trying to do this in the work of drawing the chisel line or the center line in one-shot plate making, the PS plate is adjusted to the stopper and the PS plate guideline, easily and accurately, Positioning can be done. In addition, the scale line displayed on the guide rail and the scale displayed on the parallel ruler enable accurate drawing of the chin line and the center line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIG. When a land line or center line is to be drawn on the PS plate, the lower end of the PS plate is aligned with the stopper (6) and placed on the drafting plate (1). In this case, the drafting board (1) is slightly lifted up and is in an inclined state. This is because the lower end of the PS plate easily comes into close contact with the stopper (6). PS
Position the plate in accordance with the PS plate guideline (8) while sliding the plate along the stopper (6) small to the left and right. The positioned PS plate is fixed on a drafting board (1) by drafting tape or the like. next,
Move the parallel ruler (2) up and down to set the brake lever (5) attached to the guide and brake (4) at a predetermined position corresponding to the scale margin dimension (10) displayed on the guide rail (3). Press down and fix. This makes it possible to accurately draw the necessary kaolin. Further, the center line can be drawn by using a triangle ruler or the like as an aid by adjusting the scale displayed on the parallel ruler (2) to 0 (zero). Also in this case, since the parallel ruler (2) is fixed by the brake, a line can be drawn without displacement.

[0006]

The PS plate carving machine according to the present invention performs the work of drawing the carved line and center line of the PS plate in one-side plate making.
It is possible to carry out easily and accurately without requiring a skill level as before. Further, since the work is simplified, the work efficiency is improved.
