It’s a fact all flexographic printers/con- verters understand. The faster a job can be set up, run to completion and broken down in preparation for the next job, the more jobs that can be run. Every minute that a press isn’t running is money lost. In today ’s flexible packaging market, printers throw around the words “high speed” in reference to wide web flexo presses. But what is “high speeds”? And more importantly, how critical is “speed,” in the strictest sense of the word? The answer to both questions is, “It depends.” The large majority of wide web presses in operation today are running at anywhere from 900fpm to 1,200fpm. Those are considered typical working speeds. Some printers will run at 1,500fpm, which is considered pushing the limits. When most flexo printers are thinking about high speed presses, they are referring to those that can run 1,800fpm and up. That’s because, at these speeds, you are in a different ballpark. Once you start looking to 1,800fpm or more, many flexo print- ers have to consider buying a new press, and need to make adjustments in prepress, etc. There are presses that can go much faster than that— 3,000fpm, in some cases. Anything above 2,400fpm is some- thing totally different. Very few, if any, operations run that fast all day every day. Those are special applications and situa- tions that are not reliable for the average production run. FASt FActS Technically, there is no limit to the speed that a gearless flexo press can run. The servo motors that drive the mandrels are not limited by anything, per se. Heck, you can adjust the top speed of your car’s engine to go 200mph. The problem is there are components beyond the motor that have to be able to run at such speeds. The same thing applies in flexo. Getting to high speeds requires more than just the press. You are talking about ink transfer, drying, prepress, and other factors. So the printer needs to be well equipped to run at high speeds. Ink is going to be a major player—what proper- ties must the ink have to get it from the anilox to the plate and then the substrate at such speeds. On top of that, how do you • Most wide web printers run between 900fpm and 1,200fpm. • Speeds above 1,800fpm only make sense on long runs. • With shorter runs, changeover times are more critical than actual run speeds. if your customers are focused on short run orders, then adopting a “pit crew” mentality to help reduce changeover times will offer greater benefits than faster run speeds. 48 FLeXO august 2010 www.flexography.org August2010_mech.indd 48 8/13/10 7:46 AM
