A grant from the National Endowment for the Arts enabled Universal Limited Art Editions (U.L.A.E.) to add an intaglio studio to the workshop in 1967. Under the guidance of Donn H. Steward, Frankenthaler produced her first intaglio print, Yellow Span, the following year. Aquatint, an intaglio technique developed to create tonal effects in prints, was particularly suited for the artist, who preferred that her color pour, spill, bleed, or flood the picture’s surface.
