Pre-press Technology Evolution of the Late and its Effect on the Print Quality
Abstract:The train of disruptive developments in reproduction technologies, following the halftone photoengraving invention in the end of 19th century, was concentrated within the last forty years. The electronic reproduction of 50-80ies using at first the analogue and then the digital signals processing was later replaced by the computerbased pre-press systems. The latter, in their turn, have undergone during last decade the fast transformation from the closed (vendor proprietary) to the open ones of today. Enabling essential advantages compared to the previous one, coming to every next step was however characterized by certain compromises – in terms of either deterioration in picture quality, or some inconveniences in processing, etc. These compromises were somehow being overcome in the course of periods of development before entering the next phase, but some are still waiting to be solved. The qualitative leaps in the general approach to picture processing in pre-press have also happened within the period discussed. Insufficient facilities for proper control of the print parameters of 60-70ies were replaced by the lack of knowledge in terms of extent and direction of image transformation for providing the optimal quality, while the control facilities have become practically unlimited. The creative and technical aspect of picture processing once separated from the use of electronic reproduction, nowadays are again mixed in desktop applications.
Considerations of the kind described are important to be taken into account for the pre-press technologies optimal use and development as well as for the training and education methods.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
