Joachim,

I have developed litho film and made enlarged negative for ten years
with dilute HC-110 and acidic acid stop and have NEVER had any
pinholes. Hate to break the news - looks like you've offended the
gods. Either that or your mixing your developer with seltzer water.
Sorry, maybe someone else has experienced this. What type of film are
you using ? Could that be the problem ? I like to use Kodalith 2556.

Jeff
