PURPOSE:To obtain a gravure cylinder etching system of a low cost and high accuracy by forecasting the progression of etching of a gravure cylinder with the etching start point of copper as a time series and controlling the state of etching with means for changing the concn. of etching liquid, changing the number of revolutions of the cylinder, etc. CONSTITUTION:The operator inputs initial set values of a cylinder size, the number of revolutions the concn. of etching liquid, liquid temp., etc. to an input terminal 1, and upon starting of etching, he observes the scale. At every changing in th color of the scale, he treads a foot switch 5 to input the change in color to a CPU3. The CPU3 displays the forecast figure of the case when the current etching state continues from this and the etching progression model for the progression of etching of the gravure cylinder with the etching start point as a time series stored in a storage device 4 in a CRT display 7 via a video interface 6 and displays the action that the operator is ought to make. |
