That's a very good point and I am checking with the manafacturer to see if their mix would work.
oil based enamel is also a problem as it is not compatable with shellac over the longer term. It also tends to be fatty and hard to spread evenly and that is why I have been seeking a shellac based solution.
If the ink holds on the surface long enough for the water to dry then I should not have a problem but of course if it breaks into blotches it would be no use.
I will look at printing ink if the shellac is out of the question.
It may be I need a solution that bypasses water but still uses shellac.
