The amount of wear changes subtly. In addition, since the solvent component in the electrode ink 1 gradually evaporates during printing, the viscosity of the electrode ink 1 increases with time, and the solid content in the electrode ink 1 also increases. This leads to an increase in coating amount.

However, since the electrode ink 1 must also be present in the viscosity adjusting means, the necessary electrode ink 1 is required. However, there is a problem in that a large amount of is required and waste occurs.

It was measured by the applied coating amount detection sensor 23. The results are shown in (Table 1).

The amount of coating gradually decreases due to the rise in the temperature of the surface of the ink cylinder 9 by adjusting the temperature of the plate cylinder 10.
It can be seen that the coating amount is controlled. However, the reason why the amount of coating increased when the temperature reached 80 ° C. was that the solvent component volatilized violently due to the temperature exceeding the boiling point of the solvent in the ink 9 and the solid content ratio in the ink 9 increased.

れたことになる。As can be seen from Table 2, by changing the surface temperature of the plate cylinder 10 according to the present invention in accordance with the viscosity of the ink 9, the desired coating amount at the start of printing is reduced to the end. It is clear that this was done. On the other hand, in the comparative example in which the temperature is not adjusted, the result is that the coating amount gradually increases. This means that the coating amount increases due to the gradual change in the viscosity of the nickel ink 9, and the coating amount is changed by changing the surface temperature of the plate cylinder 10 in accordance with the change in the viscosity of the nickel ink 9. This proves that it can be kept constant.
