The Indigo Customer Exchange (ICE), the independent users group for owners of HP Indigo Digital Presses, has just announced the publication of its online directory of digital print providers. This "opt-in" directory contains information on nearly half of the 250+ ICE members. Each listing includes the pertinent contact information for the company as well as a brief description of the kind of work they do. Listed companies are grouped by state to allow a prospective print buyer to easily locate an Indigo shop in their geographical area. The directory can be found at http://www.indigousers.com/printerdirectory.htm.   "For print buyers and marketing managers looking to capitalize on the superior quality of HP Indigo Digital Presses, it's not always so easy to locate a printer in their marketplace," stated Michael Vinocur, managing director of ICE. He added, "Rather than wading through Google searches, we're helping the customer that wants to print on an Indigo to more easily find a service provider nearby. We're already getting reports from ICE members that they've begun to pick up business as a result of the directory."   Founded in 1995, the Indigo Customer Exchange is the largest digital printing users group in the world.
