I have a question about dry plate frilling.....

[GOSKINO]

I've made dozens of dry plate with alum hardening solution... Half of them are Plain bromide-iodide solution and another half is Ammonium plate.
But there's a problem about 'Frilling' of plates...
I've Researched few books and some papers and there is numerous solution of this problem
1. Apply less Emulsion on plate
2. Add more Alum solution in Emulsion
3. Use proper Fixing bath instead of water
4. Use Hardening Fixing bath

So, I've tried 1 and 3. And 2 is being ended as a Total faliure

For 3rd Method, I've used 2% solution of Acetic acid and 4% solution of Acetic Acid as a Stopping Bath
2% solution of Acetic Acid Worked Quiet well.....But 4% solution of Acetic Acid turned out a total mess...
(Even 2% solution of Acetic Acid can't stop all of frilling)

Currently I can't get a hardening fixer..

Can you experts can give a solution of this problem...??

I've been making plates for about a year now. The only time i've had problems with frilling has been when my processing temps have been too high or inadequately cleaning the glass prior to coating. I don't use alum or any hardeners in either the emulsion or in processing. I keep my temps a few degrees below my normal film processing temps and make sure to keep all solutions close to the same temp - usually in the mid-to-low 60s. I use plain water for a stop-bath. The processing times are a bit longer, but it keeps the emulsion from getting too soft.
