The image is a portion of a larger computer generated piece created as a tessellation in Adobe Illustrator. The selected image was sized, color balances and a transparency halftone (55 lpi) image carrier was created in Adobe Photoshop. DuPont ImagOn film was adhered to a zinc plate, the plate exposed, developed , and the emulsion hardened. Thereafter the plate was treated in the usual manner for intaglio printmaking, prints were pulled, and color was added by hand. I am using Keith Howard's book "Non-Toxic Intaglio Printmaking" as a guide and reference.
