However, the reduced waste management costs and increased protection of the environment make the investment worth considering. Protect process baths that spoil easily by keeping them containerized. Small scale photo developers can containerize process baths and use glass marbles to bring the liquid level to the brim each time the liquid is used. Plate Processing Replace metal etching processes with a process that generates less waste whenever possible. Printing and Finishing Recover as much ink as possible.
Preclean ink trays with rags before rinsing with water.
Fill ink fountains only enough for a particular run or shift. Return all unemulsified inks into their covered containers. To minimize waste ink generation, clean ink fountains only when changing colors or when the ink might dry out between runs. Install automatic ink levelers to keep ink fountains at their optimal level for good print quality in large web presses. Run similar jobs simultaneously to minimize waste generation between cleanup and start of the next run.
