Daniel de Simone – författare

The combination of the woodcut - a print method devised early in the fifteenth century - with Johannes Gutenberg's revolutionary invention of printing with moveable type resulted in a powerful explosion of information and ideas. For the first time, it was possible to use a mechanised system to print identical copies of books containing both text and images. Featured in A Heavenly Craft are the earliest surviving examples of these books from throughout Western Europe, all printed within the first century after Gutenberg's invention.The contributors bring these rare books to life, exploring the evolution of the technique, composition and colouration of the woodcut beginning with the earliest publications.Many of the woodcut designs grew out of the tradition of manuscript illumination, in which book illustrations were painstakingly executed by hand. The authors also present the distinguishing features of national style and taste, treating the reader to examples from Germany, Italy, France, Spain and the Netherlands.In addition, A Heavenly Craft describes the provenance of these volumes, providing an account of how Lessing J. Rosenwald purchased them from the heir to the Lea and Perrins fortune and later donated them to the Library of Congress in Washington D.C.These early printed volumes are the predecessors of today's illustrated books. A Heavenly Craft celebrates these origins, making these early publications available to bibliophiles and print lovers.

Dieses essential befasst sich mit den Prozessketten zur Herstellung optischer Komponenten für LED-Beleuchtungsanwendungen. Mit Blick auf eine wirtschaftliche Fertigung der Komponenten gehen die Autoren besonders auf die Möglichkeiten zur kostengünstigen Replikation durch Kunststoffspritzguss oder Rolle-zu-Rolle-Prozesse ein. Sie thematisieren die notwendigen Fertigungsschritte für die Werkzeugherstellung genauso wie die messtechnische Charakterisierung der Kunststoffkomponenten. Dabei zeigen sie die notwendige Maschinen- und Werkzeugtechnik, mögliche Verfahrensvarianten, die verwendeten Materialien und entsprechende Beispielgeometrien auf.
