Executive Summary
In September 2005, the author presented an investigation comparing the costs of processing gravure cylinders and web-offset plates. This investigation was a follow-up of a study he made 20 years ago when he was the Secretary General of the European Rotogravure Association.

Abstract
Ink mileage curves have been studied for many years. Several models for curve fitting have been reported by different researchers. The regression coefficients derived from curve fitting were found to be very useful for comparing different inks and were related to some properties of ink and...
Abstract
Recently, water-based inks have been of more and more interest to the printing and ink industry because of their environmental benefits. Compared with solvent-based inks, water-based inks have more complex formulations because of their higher surface tensions, lower drying speed, foaming...
Since the discovery of the transistor in late 1940 by scientists at Bell Laboratories, the world has witnessed the development and proliferation of microelectronics. The transistor led the revolution from dependence on mechanically driven heavy machinery to electronically controlled machinery and...
Topics: Dot Values and Doctor Blade Angle
What is the Sustainable Building movement? Why should gravure printers care about environmentally responsible building practices? What’s new about being “green?”
Sustainability is a word often heard these days, but not well understood. Simply defined, sustainability is the delicate balance between...
Over forty years ago, I started to develop and design the first chrome tank with platinum-coated titanium anodes, (compared to lead anodes, which were in use at that time). Today, I am still developing and improving the plating process. Copper plating is, so far, the only process that is absolutely...
Abstract
To bring gravure technology into the classroom and laboratory, the author visited a gravure engraving plant. With photographic illustrations, he describes an automated engraving operation and a manual-oriented cylinder proofing operation.

Gravure imaging by means of cylinder...
Doctor Blade Function
The function of the doctor blade is to remove unwanted ink, adhesive, or coating materials from the face of the rotating gravure cylinder, leaving ink or coating materials that can be transferred to a substrate only in the recessed cell of the image area. The widths of even...
