“Lines of Alternative Fuel” is a polymer plate etching n Somerset Warm White printed in 2010.

Image:
*Take many digital photos of a snowbound cornfield and import them into Photoshop.
*Choose an image, convert it to black and white, manipulate the image for contrast, cropping, & sizing, while eliminating and augmenting the image.
*Print out the image and draw on the print-out to further enhance it.
*Scan the print-out back into Photoshop and further manipulate it, then print out a transparency.

Plate making and printing:
*Place an aquatint screen face down onto a small piece of photo-sensitive polymer plate and expose it to UV light in an exposure unit.
*Place the positive transparency face down onto the same plate, choose an exposure time, and expose it again.
*Develop the test plate for one minute in luke warm tap water, gently moving the water, wipe off the plate surface gently with fingers, rinse, then blot the surface and blow dry it.
*Expose the plate surface to UV light to harden the plate.
*Print the plate intaglio, wiping the surface clean and leaving the ink in the recessed image areas.
*Compare the resulting test image to the transparency to judge the appropriateness of the exposure time. A second and third test plate with different exposure times may be necessary until a satisfactory time is determined.
*Finally a polymer plate the full image size is first exposed with the aquatint screen, then with the positive image transparency.
*After hardening the plate it is left for 24 hours or more before printing.
