TECHNOLOGIES & TECHNIQUES A TIME SAVER The dry ice blast cleaning process is capable of removing paper pulp, grease, dirt, and dry ink depositions on inking areas, gripper bars (including diamond coated without risk of dam- age), side walls, feeder/delivery units, rollers, drums, ink trays and other components, which, if not cleaned properly, can cause alignment problems and result in low print quality. The process can also access tight and confined areas on the printing press that are not reachable by hand, which helps to deliver a more complete clean. This also saves time. Because rollers and cylinders can be removed to provide easy access to all surfaces, both sides of color decks can be cleaned with dry ice blasting in as little 10-15 minutes before returning to production. One person can use a dry ice blasting machine to clean equipment faster than it would take a multiple-person maintenance crew to clean the same equipment using traditional methods. In fact, cleaning presses with dry ice blasting reduces the cleaning pro- cess to a few hours, versus an entire night shift or several days that it may take with traditional methods. In addition, because dry ice blasting can be done quickly, it allows printers to spot clean their presses more frequently, which will further help to maintain print quality. Since dry ice blast cleaning is a dry process, it will not wet the surface or cause equipment to rust, and it is safe to use on any electrical components. Dry ice blast cleaning is also helping print- ers to reduce their dependence on chemical solvents that deplete the ozone, as well as the need to use water for cleaning projects. Dry ice blast cleaning is an envi- ronmentally responsible cleaning solution, making productive use of otherwise unproductive CO2 . Like many companies, printers are under pressure to improve qual- ity and reduce costs and waste. The Cold Jet report found that 49 per- cent of packaging companies have produced poor quality products as a result of a poor cleaning job, while 77 percent of those companies still ranked the effectiveness of their cleaning methods as good, very good or excellent.3 Among many companies, including printers, there is often a disconnect between ef- fectiveness of cleaning processes and product quality. These same companies may not directly see the direct impact that cleaning has on product costs. With dry ice blasting, cleaning can be integrated into the production process, which increases production time, and reduces scrap rates and press damage or erosion. Labor is reduced, as well as recur- ring expenses of cleaning materials and waste disposal. During the past 20 years, dry ice blast cleaning has gone through a series of innovations that have made today’s cleaning systems more viable and reliable cleaning solutions for a variety of industries. Today, dry ice blast cleaning systems are helping printers to become more efficient by supporting Lean initiatives and eliminating unnecessary steps in the cleaning process; more green by delivering a more environmentally responsible cleaning solution and more effective by reducing cleaning costs and times and increasing productivity. ?
