Make the most of your screen-reclaiming efforts by following the tips presented here.
When it comes to a pressure washer, why use a heavy-duty, industrial unit instead of a consumer system? If you are not a home-based or small studio cleaning and reclaiming one or two frames a week, you should invest in a heavy-duty, commercial system. Investment in inexpensive systems will cost about $200. If you’re a shop that spends an hour or two per day reclaiming screens, then you will most likely burn though this type of pressure washer in six months to a year. By the time you add up replacement costs and time lost printing to searching out a system, it makes sense to invest in a pressure washer with 1500 psi that has an adjustable spray nozzle (anywhere from $795 to $925 on a proven, industrial system that will last close to a decade). An added benefit to a commercial system is lower noise output.
Reclaiming a screen
First, evaluate environmental considerations by seeking out an economical, proven product group that is environmentally friendly. Small shops or home-based studios, where space is minimum, will be grateful for low-to-no-odor, citrus-scented chemicals that are drain-safe. But for all companies, no matter the size, it is important to start to make this swing on behalf of our families, communities, and the planet.
Screen degreaser is used prior to coating a screen with emulsion as the need to remove dust and other particles is primary. Choose a biodegradable, ready-to-use chemical, if possible. The product will allow for non-abrasive mesh treatment, acting like a wetting agent for use on all synthetic and wire screen mesh. Ideally, it will offer an even sheeting of water for complete, uniform stencil adhesion to improve film lamination and bonding of direct photo emulsions.
