Summary

Gravure is losing package printing market share to Flexo in North America. Closing the cost gap between flexo and gravure is a prerequisite to regaining market share. This could be accomplished by adopting new cylinder technologies that reduce the cost of cylinder preparation and the size of cylinder inventories.

Cylinder Smarts – A Comprehensive Guide to Essential Gravure Technology

Lead Author: Philip Pimlott

As Gravure Presses have embraced technology, becoming faster, more economical and less labor intensive, the Gravure Cylinder has endeavored to keep pace.

“Overpriced, long lead-time, outdated technology and cumbersome, resulting in the demise of Gravure and the rise of Flexography”.

Statements like this one are some of the most common criticisms leveled at the Gravure cylinder — but what are the facts and what are the options?

Plasma Substrate Treatment

By ELISE M. SANDERS

Abstract

As a venue to improve the wettability of inks in the print industry, printers utilize surface-treatment technologies. These technologies allow adhesion of inks to plastics, polymers, films, and flexible packaging. Many treatment processes occur before substrates leave the factory, but further processing becomes a necessity due to a combination of uneven surface treatment and the limited longevity of the initial treatment. Popular processes today include corona,

Gravure & Its Role In Printed Electronics

By RYAN HILL

Introduction

Conventional printing processes, such as gravure, may be able to revolutionize the way electronics are manufactured. The trend in the electronics industry is towards smaller products, lower prices, and more reliable products (Pudas, 2004). Traditional semiconductor electronics require a circuit board in order to function. To date, most circuit boards have chips, transistors, and other components that are soldered to a sheet of fiberglass.

Digital Proofing Of Gravure Spot-Color Printing

By YU-JU WU

Summary

Spot color is widely used in gravure printing to obtain a colorful appearance. With new developments in printers, inks, and media, an inkjet printer can be treated as a digital proofer for gravure printing, providing significant time and cost savings compared to conventional procedures for job approvals. The implementation of digital proofing is integrally related to color management. In the digital proofing process, a third-party RIP can be employed to interpret raster and vector data files for a specific printer,

Color Management Investigations For Rotogravure

By CHRISTINE WHEATLEY
February 2005

Abstract

In the gravure industry, having a proofing press that is used to simulate the visual characteristics of a finished product has become common practice. It is often difficult to achieve accurate color on the proof press since it may use different substrates, inks, and run different speeds than the final press. The proofing press also introduces delays in the cylinder delivery process, typically adding half a day to the production cycle.
