Picking up on Harold's question, what film are you using? Are you doing anything different? Could be bad film to plate contact.

The bristles should be as low as possible without leaving residue on the plate backing. Any signs of wear or do they still look new?Since density issues can affect anyone processing film, I'd still check that. I'd bet your service provider could check the density, and the dmax should be over 4.0.ThanksHaroldOn Tue, Jul 9, 2013 at 2:18 PM, Ian Bristow <ductormanpaperboy@...> wrote:Hey Harold
The lines are getting fatter, I find that it is almost like there is a stroke around some letters and some lines. It is hard
to capture a good image of the plates with the camera. But I am 99% certain it is the brushes causing the problem
by not washing away the excess material. I will be getting some new brushes soon but just wanted to eliminate
any other possible problems. I have never had any issues with the KF95 plates, the only thing I have changed
over the last year is the back exposure for 25 seconds. Since I put in the new bulbs in if I back expose the plates they
will not wash out properly so I avoid that step now. I have been using a good service provider for the film and the
density is not an issue. I'll try and get some pics to send along.
Oh and glad to hear that the chaps across the pond are embracing modern technology:) I'm sure they do not make
the bulbs over there either as I think that the company that makes these machines has been out of business for the
last gazillion years.
