exposure question

862 Views 5 Replies 5 Participants Last post by  Ken Styles

Am using speedball diazo emulsion with a 1000 watt worklight at about 12-15min. If I can see the outline of the transparency in the burned, exposed, developed emulsion does that mean I am overexposing or underexposing?

Flames out!

It may not mean either. How is the screen washing out?
The image washes out quickly with the sprayer. Thanks once again for the exposure tester.
I will be using the exposure calculator thank you.
That just means the edge of the transparency is casting as shadow on the screen.
Not a major issue as long as your design is burning good. Just tape it up or use some old emulsion or blockout fluid to cover it up.
