I just visited with a lithographic printer that runs 2 Heidelberg GTO-DI 5-color presses, for which they currently use a blanket wash that contains 35% n-hexane and 29% toluene, and the remainder isopropanol and petroleum naphtha (about 330 gallons/year). They are interested in finding alternative products that contain less hazardous air pollutants that will still perform well with their presses. Apparently these presses do not have a fountain solution, so they have some specific requirements regarding press washes in terms of quick evaporation. While I have limited technical expertise in lithographic printing, I understand that everything is dependent on everything else, but I thought I'd throw out the question on whether anyone has experience with this type of press and using alternative products that are lower in HAPs and/or VOCs. What about water miscible washes? They currently use their products "straight". Thanks in advance. Anne Kaufmann
