Washing process:
Please use the concentrated ammonia water (25% concentration) developing, setting the temperature between 65-85centigrade developing, due to different ammonia water the imaging machine have different effect, in order to get a satisfactory density, please take two or more than twice developing.
Remark: If developing under the high temperature (100centigrade abov |
