MONTRÉAL, QUÉBEC, CANADA--(Marketwire - May 19, 2010) - Worldcolor (TSX:WC)(TSX:WC.U) has signed a multi-year extension agreement with Kensington Publishing to continue producing millions of mass market paperbook books for the New York-based publisher. Through its Kensington, Zebra, Pinnacle and Citadel press imprints, Kensington Publishing releases close to 500 new books per year, with its mass market line emphasizing romance, thrillers, westerns and mysteries.

The new agreement includes additional work in the form of highly decorative cover treatments that have transformed the look and feel of paperback mass market books in recent years. Worldcolor's foil-stamping, embossing, specialized ink and coating operations will be used to enhance the visual impact and appearance of Kensington covers.

Steven Zacharius, Kensington's President and CEO, said: "I'm very pleased with our continued association with Worldcolor, which now spans over 20 years. Kensington is the largest independently owned mass market publisher in the country and Worldcolor's excellence in manufacturing has enabled us to continue our growth in this area."

Brian Freschi, President, Worldcolor North American Operations, said the Kensington agreement underscores Worldcolor's strong commitment to mass market books: "We are a North American leader in mass market book production thanks to strong relationships with successful publishers like Kensington."
