FLEXO Magazine : January 2012
Saturday, March 17–FREE Pre-conference session 1:00pm - 5:00pm FQC (Flexo Quality Consortium) Day FQC Day will consist of two concurrent sessions designed to provide the membership with a better understanding of the factors controlling the quality of the flexographic printing process. Fundamentals of Flexo Session Coordinator: Duane Woolbright, Flexographic Technical Association This pre-conference session serves as a foundational or “prerequisite” seminar to the topics discussed throughout the Forum. The main objective of this FREE seminar is to bring novices up to speed on the language of flexo, the markets, the segments, the major elements and the basic practices, with a focus on the flexo press. It will introduce attendees to the basic flexo principles, practices and procedures to help them better participate during the Forum and in FQC activities (and well beyond). Presentations will include a brief primer on flexography, press technology, graphics principles, and process components, including substrates, inks, and plates. The session will be augmented with a virtual press tour illustrating the principles involved. Flexo Industry Overview An introductory session providing the novice user with an understanding of the flexographic industry including market segments and the products they print such as flexible packaging, multi-wall bag, tag and label, corrugated, paperboard and envelope. Key resources will also be discussed for anyone wishing to learn more about the topics presented through the Forum or who just want to get more involved in the industry including the FTA, the meaning (and value) of FIRST and what the FQC committee does to advance flexography. Bill Malm, Harper Corporation of America Flexo Terminology and the Basics of Ink This “flexo primer” will introduce key press components and often used graphic terms including a look at a basic flexo print station highlighted by the anilox. This overview of what makes flexo truly unique will set the stage for the rest of the sessions. Likewise, prepress and related printing terms will be defined including dot gain issues, compensation curves, gray balance, tonal range, ink film thickness, solid ink density, traps, vignettes and more. A discussion will follow on the types and qualities of various inks most often used in today’s presses such as water-based, solvent and UV. Rory Marsoun, EskoArtwork Press Configuration and Virtual Press Tour Stacked, central impression, inline and even sheet-fed flexo presses will be illustrated in this segment on common press types and configurations. Differences and capabilities of each will also be discussed from narrow web label to wide web film presses. Then the conversation moves to a “running” press as we take a guided tour of a virtual press in action showing the key processes, features and components in motion. Joe Tuccitto, FTA’s Technical Education Services Team (TEST) Substrates on Press and the Ink Metering System This segment will look at the difference between poly films and the various paper stocks available including run characteristics and performance capabilities. Common printability issues will be highlighted for each as ink hits the various substrates in question. As the substrate moves through the press, attention will move to the ink metering system itself and the interaction between doctor blade, anilox, ink and plate. Special consideration will be given to setting the proper KISS impression – anilox to plate and plate to substrate. Kern Cox, Sonoco Institute - Clemson University 4 SeSSionSFreeforallattendees
