SAUERESSIG GmbH + Co. PRESSRELEASE „Flexo & Tiefdruck“ 2-2002 Please check German version for pictures. Flexo or gravure printing forme? The early stage costs in the flexo and gravure printing from the point of view of the repro and printing forme manufacturer Saueressig. Kilian Saueressig The company Saueressig, Vreden/Germany, exclusively uses digital manufacturing procedures for the production of the listed flexo and gravure printing formes. The basis for the following details and assumptions, are internal experimental values, production data, customer information and the personal assessment of the management. For the decision-making for one manufacturing procedure, the qualitative and economical demands on the product are to the fore. The election of the printing process and therefore also the decision for a technology of the printing forme manufacturing, are only made by the printer or the brand manufacturer regarding to the experience of Saueressig. In this occasion the forme manufacturer takes the function of service and advice. Relating to the production course, the company produces gravure as well as flexo printing formes in different types. Therefore a change between the both printing processes is possible without problems in this company. Today the job sequences in the reproduction and thus also the costs for the gravure and flexo printing are roughly equal. The reasons for the costs approach are arranged in the use of same hard and software and in the workflow which is composed of it. Therefore, they talk also about the “digital central reproduction” on the market today. A cost influence arises of the quality claims for the proof technology (e.g. cromaline, Iris or HPproof) respectively used. In the flexo printing, we distinguish between the following printing formes: Photopolymeric flexo printing formes - Plates. - splitting of the processes - effort for assembly at the printer - costs are distributed on the printing forme manufacturer and printer. - Endless sleeve (e.g. Digisleeve). - provided with pre-assembled plate. - can be used at the printer without further effort of assembly. - short make-ready times
- excellent register as plates are assembled before laser - at the production run high flexibility and availability. - costs concentrate on the forme manufacturer - Endless/seamless sleeves. - facilitate a seamless conversion of line and screen elements. - obtaining of the respectively sleeves with corresponding surface. - illustration at the forme manufacturer. - costs are distributed on the supplier of sleeves and the forme manufacturer. Direct structured flexo printing formes - Gummed or synthetic materials. - endless/seamless printing formes. - flexo printing with UV-colours. - obtaining of the respectively sleeves with corresponding surface. - illustration at the forme manufacturer. - costs are distributed on the supplier of sleeves and the forme manufacturer. In the gravure printing, we distinguish between the following manufacturing processes: - Electronic engraving of gravure printing formes. - variable-depth and -area process: variable area and depth of cells. - half-tone manufacturing (lasering and etching). - variable-area process: constant area of cells, variable depth of cells. - conventional production. - variable-depth process: constant area of cells, variable depth of cells - direct structuring of gravure printing formes (please see Flexo+Tiefdruck 1- 2002, page 54). - solitary digital laser engraving. - great spectrum in the area of cells and flexible screen dot formes. - lasering of half-tone, semi half-tone, conventional cells and their combination - replaces the conventional etching at Saueressig own reproduction foreign reproduction laser installation for laser installation for the the manufacturing of DIGITAL ASSEMBLY half-tone manufacturing photopolymeric plates of gravure printing formes laser engraving installation laser installation for the electronic engraving for gummed and synthetic manufacturing of installation for the flexo printing formes direct structured gravure manufacturing of gravure printing formes printing formes
