Technologies & Techniques Pushing the Press to its Threshold Maintenance and Testing Will Help you get There By James etheridge Presses are being pushed to run faster and faster. With servo technology, they are running smoother and smoother, which enables them to hit much higher press speeds. Speeds of 500fpm are not the norm anymore—it is 750fpm and 1,000fpm. In the past, you had a press that was capable of running 500fpm, but the production speed on your floor was more like 100fpm, 150fpm, and if everything was running good, 200fpm. When you ask printers why they run it at those speeds, they have a long list of excuses. Half of a press’s actual max speed is a dream come true. But with any press, be it servo or gear box drive line, you need to be able to control the variables to push the press to its threshold! TesT everyThing To push a press to its threshold, you must have all the variables in peak working condition, and even then you need to setup proper testing procedure to catch and define the is- sues before they become problems. This is a very competitive market, which is continually pushed by cost, and the only way to be competitive is to boost the performance of the press and its consumables. On the consumables side, finding a cheaper product is good, but is it giving you what is needed, which is optimum performance? Not properly testing the consumables can have an adverse effect on the end product. Pushing all these vari- ables to their threshold can and will have its consequences unless proper testing procedures are put into place. • How involved are your press operators and mainte- nance department in your preventive maintenance program? • Do you unitize your vendors enough on their respec- tive products? • Is this the proper product to achieve the press thresh- old? • Set up an open forum to discuss preventive mainte- nance and housekeeping with your printing depart- ment. • Do your press operators and supervisors properly test for issues that you see? • Do you have proper testing procedures on the end product to catch a problem before it becomes an issue? 90 FLeXO noveMBer 2010 www.flexography.org FLX_Nov10_mech.indd 90 11/1/10 2:26 PM
