A couple of suggestions:
With MIS ink.
Temperature is important - I have not had much success below 230 C
- or above 240 C.
Ammonia will help remove the cured ink residue after etch.
I use the same oven at a lower temperature and Plumbers Paste as the
tinning medium. There is no need to remove the cured residue the
Plumbers Paste paste takes care of it. The boards come out nicely
tinned. -This is the non water soluble variety of paste.
The key to fine traces MAY be to reduce the "liquid" content of the
ink increasing the "solids" content while still getting the printer
head to pass the ink. This is what I am working on now.
Good Luck!
