"Deep etching problems while using Dry Film"



April 2, 2017
60423

Q. Hello,

my name is Thomas Müller, we are Platemakers in Germany, specialist in UV printing commercial advertising plates; now we want to etch Plates for embossing with FeCl3.

Our results with the Bungard Jet 34D are not good yet. We have a big order but still can't handle the problems.


Our Blue dry film 50 mic is lifting from the plate after 7 minutes of etching, so we have big underetching and no sharp corner; we need to go 1,5 mm deep into the Brass.

Can anyone give me resources for a good application of the film?
The Brass was completely cleaned from fat and oil; we make it a little bit rough too; laminate with water; make a second exposure after developing and dip it a few seconds in 80 °C water for relax the film.

Best regards
Thomas Müller

A. Way, way back in the 1960s, we etched iron cylinders with numbers and letters using FeCl3. It was no problem using Kodak MER (Metal Etching Resist).

MER is long gone, but maybe someone at Kodak can tell you whether that product is now available elsewhere.
