Abstract
An inspecting liquid is dropped onto a resist layer formed on a gravure printing plate and is allowed to permeate the resist layer or gelatin resist layer to reach the printing plate so that a short circuit is formed between the inspecting liquid and the printing plate. The time required for forming the short circuit in the resist layer is measured by utilizing an oscillator pulse counting circuit to determine the conditions of the resist layer thereby to improve the quality of the finished printing plate.
