Which Safelight?
« on: June 25, 2019, 04:08:37 PM »
Hi Folks,

I have Saati Textil PV emulsion, on the container is says to use yellow safe-lights when applying. I only have red safe-lights. Can I use those or do I need to buy yellow?

Thanks.
Bart

red is fine, but you should look into yellow. so much easier on the eyes.

or just swap them to LED with a UV filter cover.  It's amazing to actually be able to see in the screen room.

Yellow "bug lights" work too, depending on what kind of fixtures you're working with.
Nice guys laugh last.

Don't need em anymore as we don't use Darkrooms.

Our screen room is a normal room with regular tube lights in the ceiling. We coat, store, image, burn and even washout screens in regular shop light conditions.

No need to shut off the lights until we leave at night.

Old screens rest in front of coated screens as they lean against the wall to be imaged.

What's the situation for drying coated screens? A cabinet? The only piece of the puzzle not mentioned.

Amen!! Thanks John for the post. Its hard to believe people sitill coat in the dark. I know ya'll flip screens thru quick but would you agree the yellow tubes do add a level of safety for the shops that might have screens coated and store them for a few days or even a week?

In a room next to coating with a heater and a fan. Those bulbs are wrapped with an old piece of Rubylith. That is the only 'safe light' we use and I bet those bulbs were wrapped years ago.

Yes they can add a level of safety if one so chooses to do so.

I don't use any safelights or a darkroom. As long as you work fast and don't expose your screens to direct sunlight you will be good.

That all depends on many factors. In one shop we used blue welders filters. Coated screens would last to upteen months.
