In the above-described registration adjustment display device in the background art, a sheet-fed printing machine, work is limited to sheet products, and K, C, M, Y printing, etc. on one side are often used in a fixed manner. There is no confusion in registering operations. For example, when M (magenta) is moved backward by 0.05 in the vertical direction and moved to the operation side by 0.17, the button g3 of the _third printing unit is selected by the input means d in FIG. It is understood that the above numerical value 0.05 / 0.17 is input and the register button in the designated direction is pressed.

  However, when form printing is performed on continuous paper using a plurality of replaceable cylinder form printing machines, it is difficult to intuitively operate with the input means d as shown in FIG. As an example, when performing 8-color printing and performing front and back multicolor printing, a turn bar or reverse running method is used for paper reversal, and offset printing (3 cylinders) or convex printing (2 cylinders) is used for printing. When offset printing of K, C, M, and Y is sequentially performed for the 1st to 4th colors and the reverse printing is performed with the turn bar for the 5th color, the left and right registration adjustment directions for the 5th color and after are 1 It would be the opposite of printing 4 colors. In addition, when backing with convex printing in the reverse run mode with the fifth color, the operator must rely on memory and memos whenever the combination of paper thread and exchange cylinder changes, such as the top and the left and right are the same as the previous stage. Was operating. Furthermore, in form printing, special colors and desensitizing ink are used in addition to the front and back sides, and the relationship between color and used color is not fixed as in a sheet-fed printing press. I was relying on my notes.

  As described above, in the prior art shown in the background art, the registration adjustment work is confused every time the paper thread, the exchange cylinder and the ink used are changed, or the ink is erroneously supplied. It was difficult to operate for features that were difficult to understand.

  The present invention has been made in view of the above, and operates registration adjustment work when changing printing conditions of each printing unit such as paper threading, change of offset printing and convex printing by plate cylinder exchange, change of ink used, etc. It is an object of the present invention to provide a register adjustment display device that can be intuitively and smoothly performed on a panel.

  In order to achieve the above object, the register adjustment display device according to the present invention has different printing conditions such as reverse printing, front printing, turn bar reverse printing, offset printing, and convex printing, and each has a registration adjusting mechanism. In a registration adjustment display device in which registration adjustment of each of a plurality of printing units is performed using a single operation panel, a unit button for designating a registration adjustment mechanism of each printing unit on the operation panel, and each printing unit A condition designation button for designating printing conditions, a plurality of movement amount setting buttons, and a registration adjustment mechanism for the printing unit designated by each unit button are set by the movement amount setting button according to the designation by the condition designation button. Movement command having buttons for instructing forward movement, backward movement, OS movement, and GS movement over the amount of movement It has a configuration provided with a tan.

  In the above registration adjustment display device, the unit button can be changed in color, and a color selection means for selecting the color of the designated unit button is provided on the operation panel, and this color selection means is a color code. The color sample buttons used in the printing unit cover the shades of each color, or this color selection means is an ink line-up display.

  According to the configuration of the first aspect of the present invention, the printing conditions of each printing unit, that is, the reverse reverse printing, the front printing, the turn bar reverse printing, the offset printing, and the convex printing can be designated on the operation panel. Registration adjustment work can be performed intuitively and smoothly on the control panel when changing the printing and offset printing by changing the paper thread, plate cylinder exchange, and convex printing performed according to the change in printing conditions of the printing unit. In addition to reducing mistakes, it is possible to significantly reduce work load, waste paper, and loss time.

  According to the configuration of claim 2, the color of the designated unit button is made the same color as the ink used in the printing unit corresponding to the unit button by operating the color selection means provided on the operation panel. This makes it possible to eliminate unit button selection errors when registering each color. Further, the relationship of the ink used in the printing unit designated by the unit button can always be displayed on the operation panel by the color of the unit button, and the risk of erroneous ink supply in the printing unit can be reduced.

  The above color code is a color sample button that covers the shades of each color, or an ink line-up display, so that the color of unit buttons can be easily specified even in difficult-to-understand colors such as light blue (shallow shades). Can do. Moreover, this color designation can be performed by pressing a color sample button, and the operation is simple.
