ok ive been testing the new bb640es series from hrt and they seem to be a lot more sensitive to the old bb640 the only problem is that i cant get any hologram on my old bb640s anymore, the plate seems to have lost all of its sensitivty (after exposure it gained no density what so ever). does anybody know whether or not these plates lose sensitivity in storage (cause there quite old now). email ianryan@ireland.com Also if you havent already tried the new bb640es series then i recomend you request some plates and try it is cuts exposure time down a LOT. i am going to make an order of the 8x10 paltes and start testing them.

Hello,
I have had the same experience twice. Looks like they must be used right away after receiving the plates. They should be stored in a cool place OK, but if not my experience that they are going bade after about 3 months. 195.70.188.204
