Hello!
I’ve just used a glass stage (glass on both sides) for the first time and immediately ended up with Newton’s rings on the prints.
How can I avoid them next time – using the same stage? With a hairdryer, perhaps?
Let me know how you go about it.

Hello!
I used to have an enlarger myself (a Durst 606), with which I often had problems with Newton rings – I cut a small mask out of thin cardboard to fit the negative and attached it to the top glass, and that sorted it.
With the F? you’re only making things worse – if my memory serves me right, dry air promotes the formation of Newton’s rings...
Tetenal used to make an anti-Newton’s ring spray, but I’ve no practical experience with it.

What sort of enlarger is it, then?
Perhaps there are anti-Newton glass and metal inserts available for it

The enlarger is also a Durst. Laborator 900 or Colidap 905 – there’s all sorts of information on the machine.
First of all, I’ll give the cardboard insert a go – thanks for the tip!

Hi,
I’ve had the same problem with these smudges all along. No matter which glass coating I tried… they never went away :rolleyes:
This cardboard mask has solved all my problems! Thanks, Roman! :lol:
Newton’s rings have completely disappeared and the prints are coming out fabulously! I can’t recommend this highly enough to anyone here who’s having the same problem!
To show what it looks like, in case anyone else has the same problem... here’s a photo of my solution:

The cardboard is very thin, smooth and stiff, like a playing card (that’s what I’d use). Clean the glass with methylated spirits beforehand and stick the mask on with normal cheap paper glue (apply a thin layer!). If anything gets on the mask -> dampen it briefly with methylated spirits and rub it off with your fingers.
