Postprint Graphics: How to Become a Profitable and Productive Printer!, 1992 Corrugated Containers Conference Proceedings
Tom Scanlon--ENVX MACHINE-Most machinery manufacturers now produce presses. D/C and FFG with "High Quality Graphics Capabilities". As a minimum, these machines must incorporate the following features:
LEAD FEED
A lead-edge feeder, such as this timed, belt feed system, introduces the sheets in register and in square.
PULL ROLLS
Pull rolls, if used, must be as large as possible and must be preloaded.
SHEET CLEANER - ENVIRONMENTAL SHIELDING Some form of sheet cleaning is absolutely necessary. This device uses high volume, low velocity air to vacuum the top, bottom and edges of each sheet. Environmental shielding must be used to keep the print system clean.
INK METERING SYSTEMS
