Introduction to Printmaking
-Solar plates can be a
challenge. Ron has indicated their exposure / development has varied from
semester to semester. “Printmaking in the Sun” (Dan Welden) is a useful
reference text that essentially serves as an instruction manual. Even as I
showed students transparencies, plates, and prints – there was great confusion
about the process. The major issue seemed to be that students didn’t realize
there was an exposure component AND a development component (so many questions
came after the exposure discussion that students didn’t realize there was
another step that visibly / physically changes the plate). Give students 2
plates to work with (a 5X7 inch plate costs $10). Group this with the relief
project and give students 2 linoleum blocks to work with as well. Here are a
couple thoughts on solar plates:
-Transparencies need to
be much, much, much lighter in value than you would think (based on experience
with any other photochemical process).
-Open biting occurs when
an area on the image you wish to be black is exposed and reveals a recessed
open space that won’t hold ink (and therefore prints white). Texture is
required to make it print black. Therefore the “double” exposure (1) one minute
for a halftone / texture directly on the plate 2) second exposure for image) is
required. This is also why transparencies need to be light in value.
-In a transparency, the
image area blocks light, dissolves in solvent (water), creates texture, and
prints darker.
-In a transparency, the
negative area receives light, hardens, remains after the solvent application,
remains smooth, and holds less ink.
-There is both a “relief”
exposure / development and an “intaglio” exposure / development. The intaglio
method is more akin to other photo-printmaking techniques. The “relief”
exposure essentially creates a negative of the transparency. The dark areas in
a transparency rinse away in the developer, creating recessed areas in the
plate that don’t print. The areas that remain are rolled with ink and print.
2D Foundations
-Students had mixed
results painting their forms directly for the “Not Another Color Wheel” project
(as opposed to painting color swatches and cutting shapes from them). The
advantage is that it’s more direct. The disadvantage is the technical
objectives suffer (opacity, homogenous mixtures, etc.).

General Art
-Showing one stitch and
one book form was an effective use of time. Consider creating a presentation
with a number of other book forms. I think there would have been enough time to
create paste paper in class as well. Consider purchasing a class set of sewing
needles and threads / ribbon.
