Robert Cadel, 60, the owner and publisher of Print, a trade magazine devoted to the graphic arts industry, died of cancer Thursday at Holy Cross Hospital in Silver Spring.

Mr. Cadel, who was born in Brooklyn, served in the Army in the Aleutians during World War II. He then attended the City College of New York. He moved to the Washington area in 1948 and became business manager and assistant to the publisher of the Television Digest Newsletter.

In 1959, when the newsletter was sold to TV Guide, he became copublisher of Print, establishing its administrative offices in Washington and its editorial offices in New York. In 1963, he became sole owner of Print and established RC Publications. He remained publisher of the magazine and president of RC until his death.

In 1975, Mr. Cadel began publishing "Print Casebooks." These included the winners of a graphic arts competition sponsored by Print. Last summer, he brought out "Prints Regional Design Annual, 1981," a regional survey of the graphic arts.

Mr. Cadel, who lived in Bethesda, was a member of the National Press Club.

Survivors include his wife, Marilyn, of Bethesda; a son, Howard, of Potomac; a daughter, Susan Cadel of Washington, and two brothers, Aaron and Martin, both of New York City.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
