I'm still a noob and was hoping for some professional eyes to look at my problem:
I recently ordered a Ranar CBX2024 exposure unit and have not been able to produce a perfect stencil with it yet. This could very well be user error, but I'm beginning to suspect that there is an electrical problem.
So hears the deal: I'm using an Ulano exposure calculator to determine the best exposure time for my new emulsion: Murakami Sp-9500.
As you can see, the Ulano logo is only minimally covered by the the density filters and therefore should look about the same after exposure and washout.
I have noticed some inconsistencies in how the Ulano logo is rendered after I rinse the screen:
the left logo washed out poorly, yet the right logo looks fine?
I tried carefully reinstalling the UV tubes just in case they weren't seated properly on the left side. Before I expose another screen I wanted to get some advise on how to properly install the tubes? Also I need to determine if this is an electrical problem so I can contact Ranar for a replacement (which I do not want to do!).
Am I nuts or is the light slightly brighter on the left side????
