printCafe vs. PrintTalk--Waging a PrintWar?

JDF is central to both PrintTalk and printCafe's PCX integrations. The PrintTalk implementation relies on both JDF and cXML. "JDF is excellent at describing the printed piece, but it doesn't say what we are doing with the print piece. Are we asking for a quote? Is it a change order or a catalog order? There is no mechanism for doing that within JDF," Mekis explains.
