About the lecture: The first high-quality digital photographic
printing processes entered the market in the late 1980s, and today
it is believed that more than 99% of the world's photographic prints
are being produced with digital color and monochrome processes.
Included are modern digital prints made from scans or digital camera
captures of original color and black-and-white negatives and
transparencies, from glass plate negatives, and scans made from
historical and other previously made prints.

The twelve major current digital photographic print processes will
be discussed, including UV-curable printing and a new inkjet
sublimation thermal dye transfer process for printing on large,
specially coated aluminum panels.  Recent developments in aqueous
pigment inkjet printers using newly developed inks with enhanced
permanence will be described, including the important continuing
role of silver-halide-dye (chromogenic) color prints and their
gradual replacement with pigment inkjet, electrophotographic, and
dye inkjet systems.

Exhibitions by fine art photographers Andreas Gursky, Cindy Sherman,
Jeff Wall, Joel Meyerowitz, Stephen Shore, William Eggleston, Elger
Esser, will be used to illustrate various printing processes.
Accelerated test methods for evaluating the permanence of
photographic prints, and the role of ISO and industry-developed test
methods in the marketplace will be discussed in relation to the
development of improved permanence test methods.

The event is free and open to the public.  For more information and
