Pinholes help

Post by FreakyTeez »

Okay I use diazo emulsion and was wondering is there a way to not have pin holes after coating? I have so many pin holes and I don't want to start over is there a way to cover up all the pin holes?

Pinholes are caused by 3 things..
Coating too fast
underexposing
Dirt

Slow down your coating speed
expose longer
clean your glass and clean your positives

as far as bandaging the problem... Block out the pinholes with emulsion and re-expose it ... or use tape.
