Design and implementation in a production environment of an infographic system applied to digital reprographic techniques Conception et mise en oeuvre dans un environnement de production d'un système infographique appliqué aux techniques de reprographie numérique scanner dot generator reproduction numérique image de synthèse 006 004 620 Copie Impression numérique Reprographie -- Appareils et matériel Les deux dernières décennies ont laissé libre cours aux constructeurs de stations infographiques pour proposer à leurs utilisateurs des plateformes de développement aux architectures solides et performantes aptes à modéliser puis traiter la problématique de la reprographie numérique. Une première partie situe donc le problème du traitement numérique de l'image et expose brièvement l'état des techniques employées sur le marché des solutions actuelles. La seconde partie constitue une analyse des outils spécifiques a la reprographie suivie d'une étude de leur intégration dans une chaine de production digitale. Une troisième partie présente l'étude et la réalisation expérimentale de la chaine de production appuyée sur les choix dictes par les impératifs conjugues de production et de performance d'une imprimerie numérique. Enfin, en conclusion, nous présentons une synthèse des travaux en cours assortie d'une analyse critique dessinant les perspectives d'évolution de la configuration mise au point aDuring the two last decades, manufacturers of graphic workstations have been working hard in order to design and market development platforms with reliable and high performing architectures enabling both modelisation and processing of numerical reprography. Until recently, a few big manufacturers developing specific solutions, more reliable than efficient, shared the prepress market. However, more and more software houses are choosing the conceptual and then technical design of different prepress systems based on standard hardware collecting the last available electronic and programming technologies. Every passing year, with the replacement of one workstation with one of greater performance, it becomes rather obvious that the future of the prepress industry definitely belongs to this kind of equipment, cheaper than a dedicated hardware but also and above all, more flexible, i.e. upgradable, for adaptation to new technological innovations. However, until today, none of these new architectures has ever been at the center of an experimental site within a traditional repro house. Such a development seems to be useful, even unavoidable in order to define precisely the possible evolution of those new technologies which offer, as we will see, real productive useroriented solutions. The work described in this document has led to the realisation of a system which went from an experimental level to a productive one as soon as September 1991. A first part locates the problematic of digital page layout and outlines the state of the art in the current technologies involved on the market. The second part of this work consists in a non-exhaustive analysis of specific tools to be integrated within a digital production line for the prepress industry. A third part presents the conceptual study as well as the experimental evolution of the production tool resulting from the needs of a "digital" printing industry. As a conclusion, we present a synthesis of the work accomplished together with a critical analysis proposing an evolution of the created configuration.
