Things that make you go hmm

One thing was missing at CPI Firmin-Didot: signatures. In most printing operations, it's typical to see pallets of work in process. But at CPI, it's “in dog, out sausage” on both its vintage Cameron book production system and HP T300-driven Quantum line.

Very few of the veteran industry observers had ever seen a Cameron belt press — less than 50 were built. According to Frank and Richard Romano's invaluable “Encyclopedia of Graphic Communications,” this web-fed press, specifically designed for book manufacturing, “consists of thin rubber or plastic plates mounted on two moving belts that use letterpress plates, inks and ink delivery to produce complete book signatures.”

Ribbons of books

The Magnum FlexBook slitter and accumulator for book block assembly are at the heart of the HP T300's inline finishing system. It slits the printed web into page-width ribbons, and then converts these ribbons in to collated and bound book blocks sent on to a Muller Martini Acoro perfect binder. Books can be up to 900 pages in size.

Coated paper breakthrough

The HP T300 has no click charge. A bonding agent enables it to print of a variety of uncoated offset stock, newsprint, and treated and coated stocks. Substrate options continue to expand: HP announced a new ColorPRO Technology licensing agreement with Georgia-Pacific Communication Papers and the launch of a new ColorPRO media for use with the HP T300 Color Inkjet Web Press.

HP is working with Appleton Coated on customized papers for the inkjet press based on HP-developed coating technology. Appleton Coated will manufacture papers with matte and dull finishes designed for textbooks, direct mail and additional commercial printing applications. (See “Paper & ink,” pg. 22.)
