Saphira AR 550 Pure fount

Last week a guy from Heidelberg came with this fount and said that it's very good reduces the IPA and works perfect just change the old fount with this and put the IPA on1.5% and it will be fine. After 5 days of test it's a disaster, ink is build up on the dampening rollers and I have to clean them every 2-3 hours,I have to increase the water with 30% and its still scuming.
I'm searching for some info about this fount from someone who use it successfully.
Thanks in advance.

 

There are some guy in Bulgaria that use this forum for info about this fount that's why i have to make a little clarification.After 1 month of use of this fount I can say that things are not so bad.There is no problem if you have small jobs(500-1000sheets) to run with 1.5%-2% IPA but for 10000+ sheets we use 4% IPA and it works perfect, the problems occurs only if we have long runs and the IPA is less than 3%. With 4% IPA everything works fine and it's much better than 8-10% that we use before.

 

If you weren't having problems before, why change? Personaly I don't like Saphira and I stopped printing with alcohol in the mid 80's.
Good luck
