The master of screen-printing guards the secrets surrounding his recipes and processes like the tinkerers and inventors of old. The Swiss Lorenz Boegli developed this printing technique in a quality that is unattainable for other printing processes. Together with the manufacturer, he developed the technique of RGB printing with pearlescent pigments to a mastery that is used by the crème de la crème of fashion, watch and jewelry brands for their packaging and printed matter. In cultural projects, the printer continues to develop his processes and astounds with emotional results that are only remotely reminiscent of traditional screen printing. Boegli's products achieve their maximum effect in this publication in combination and juxtaposition with offset printing in equally high quality – on exquisite paper and in careful variation. Exquisite examples of printing of the various printing processes offer an incomparable and stunning visual pleasure. Text contributions in letterpress enhance the haptic sensation of the book. Experts from various disciplines shed light on the metaphor of alchemy in relation to Boegli's mastery and its significance for commercial use as well as for the advancement of the printing industry. The publication was produced in close cooperation between Lorenz Boegli, the quality printing house Grafiche Antiga in Treviso and the traditional Italian paper manufacturer Fedrigoni, supported by Merck KgaA, Darmstadt.weiterlesen
