Efke Print film is a high silver content, chlorobromide,
orthochromatic emulsion coated on a clear 170 micron polyester base. It
was designed as a replacement for Agfa's Gevatone N31P and is excellent
for creating enlarged negatives (in a two-step process) for contact
printing. Used by many alternative process photographers the world over
as the industry standard.
It has an ISO rating of 25 and a speed of P400. Varying the
concentration of the developer can control the ISO range. For example
using Dektolâ„¢, or LPDâ„¢ in stock solution increases the contrast.
Further dilution reduces the contrast. Experimenting with different
dilutions and developing times will produce the desired results.
Efke Print film tones in all available toners: Cachet/MACO
Sepia, Selenia and Azure Blue toners. With the blue toner, underexpose
by 0.5-1.0 stops because blue toners add image density.
The Efke Print Film emulsion is relatively fast. Use a standard step
wedge to determine exposure times. Put a black card under the film to
avoid bounce back through the transparent substrate. Develop at least
two minutes with all developers regardless of dilutions.
Use a red filter during processing. Be sure the distance from tray to safelight is at least 40 inches.
