Gum is susceptible to the many variables that go into the process. In order to identify the variables I can control, I find it easier to separate the process into two parts: the negative (digital darkroom) and the print (wet darkroom).
The process I’ll be describing is what I found that works for me under my specific conditions in order to achieve the results I’m looking for.
DIGITAL DARKROOM
HARDWARE
Computer: MacBook Pro
Printer: Epson Stylus Photo 1400
Ink: Claria High Definition Ink
SOFTWARE
Adobe Photoshop CS5
WET DARKROOM
EXPOSURE UNIT
I made my exposure unit using eight Sylvania 20 W 24-inch bulbs (F20T12/350BL/ECO) about 3 inches away from the print. I use a 20×24 inch vacuum table for making the contact prints.
