Screen coating

Posted on Mon, 24 Oct 2005 at 5:10



Hello,
Is there any emulsion that is light safe; that can be take out from darkroom,to inside another room: (just like the photo emultion-coated plate in offset printing):

1. A. After coating wet condition
2. AFTER DRYING in a dryer
3. Just before exposing
4. After exposing just before washing

Or is it is a must to keep it strictly in dark-room condition ?

Thanks,

Thomas

Not that I know of, call Autotype or Kiwo or one of the other emulsion manufacturers to find out for sure.

We don't have a problem taking our coated screens out of the coating room (light safe)to the exposure unit (not light safe). It takes couple of minutes to get the screen set up before starting the exposure and we haven't seen any problem with overesposure, and we're doing 65-85 line artwork on large format screens.

what specific effects are you seeing in the exposed screens that are unsatisfacory?

Good Luck
Rocky

It is important to remember that is Ultraviolet light that exposes screens. That of course is why yellow lights work so well. Obviously taking a screen outside prior to exposing it would make it un-exposable. However it is possible to get away with bringing the screen under white light for a brief time as there will certainly be some ultraviolet light present. Flourescent tubes naturally would do more damage than a typical light bulb. of course that also depends on wattage. Is it possible, sure. Is it reccomended, no.
