Between his primary pursuit of painting and tertiary collage practice, Krushenick pursued a keen interest in printmaking. The companion book to "Graphicstudio: Contemporary Art from the Collaborative Workshop at the University of South Florida", a 1991 exhibition at the National Gallery of Art, notes that "Krushenick began to experiment with screenprinting in the late 1950s and became an active printmaker by the mid-1960s," including during a 1965 fellowship at the Tamarind Lithography Workshop in Los Angeles (which has since moved to Albuquerque, New Mexico, and been rebranded as the Tamarind Institute). At Tamarind, "he completed twenty-two lithographs during his two-month tenure," which, still featuring the more organic and undulating forms that marked Krushenick's earliest mature paintings, can be viewed here. In 1967, working with the famed Domberger serigraphy studio, the artist produced his "R3-67" portfolio, a suite of a dozen screenprints that, taking advantage of serigraphy's capacity for bright color, are significantly more vibrant and yet refined compared to the Tamarind suite and track Krushenick's broader shift toward clean, consistent line execution. The following year, published by Pace Editions and produced at Domberger, Krushenick produced his "Iron Butterfly" portfolio, a suite of 10 similarly vivid and composed screenprints, half of which can be viewed here. In 1970 at Graphicstudio, Krushenick briefly returned to lithography, producing works embracing straight lines and angular, "more architectonic" forms. In his 1971 "Fire-Flash-Five-Fade" suite of six serigraphs, Krushenick compresses and sharpens his trademark black lines into jagged bolts of electricity or shark's teeth.
