Let us be hard and sincere !

If you have a cleaning and reclaiming machine giving you such poor results as described.... Throw it away or sell it if you find an other dead pidgeon !!

We had - in my company - cleaning and reclaiming fully automatic machine for many years (since 1986) from the French manufacturer BUISINE working himself in close relation with the German chemist REMCO for product - one single product for cleaning of inks and reclaiming of emulsion - with absolutely no problems to obtain a good cleaning and the elimination of ghost images, including for very big (2,5 x 3 M) screens. We left since 1996 the use of solvents to come to an "emulsifier", no risks of fire or any environmental dangers due to VOC emissions.
The fact we were working with UV inks only since 1979 helped also to find a correct "single" chemical to work with.

The conveyor wearing the screen must be in stainless steel. I saw in a machine using a simple steel chain many problems of oxydation after a few months of use. Same thing for the belts wearing the high pressure water or emulsion nozzles= they must be both solvent, sodium hypochlorite and acid resistant.
Of course the glue used with the "stretch and glue" frames must be quite resistant, but this is something that all the (good) screen products manufacturers supply easily.
The preparartion (cleaning, abrasion), of your steel or aluminium frame before stretching the fabric must also be perfect.

There are very good German, French and Danish automatic reclaiming systems manufacturers that can be recommanded.... It is, unfortunately, often only a question of investment !
