Hello everyone, I know this discussion material is not new. I reviewed a post from 2016 that didn't lead to anything new. That's why I need the community's help to use these papers that I received as a donation.
From what I've researched, this material is completely obsolete and not used anywhere, at least in my country. According to the information I've found on Google, it's material for PMT-type graphic work, using a large static camera that illuminates the CPN negative material and, together with the CPP, is processed in a machine called CP 380. The activator is named CP 286B, which is not a paper developer; it is basically Sodium Thiosulfate with additional chemicals that I have attached in the PDF. I have tried to do all this manually with poor results or almost no results. I wonder if there is another way to use the CPN and CPP material without using rollers and activator. I was thinking about using a pinhole camera, but I haven't found any information.
If you have any idea how to use this process, or if you have a CP 380 machine or the CP 286B activator, I ask for your help to reach the end of all this.
