3 - Blot the surface of the die with a clean paper towel to dry
and reinstall the clean dies on the printer.
CLEANING THE PRINTING DIES
1 - Place the contaminated Printing Die on top of several layers
of paper towels to absorb the excess solvent. Pour just
enough solvent on the face of the printing die to cover the
die face.
2 - Using the toothbrush, carefully scrub the face of the die
to remove the contamination and old ink as shown. Add
more solvent as necessary and repeat the process until
the die is clean.
Do not submerge or soak the dies in solvent as this may cause
swelling of the rubber compound.

All inks which are formulated for printing on non-porous surfaces contain a resin binder which bonds the dye or
pigment in the ink to the surface of the material being printed. As the ink begins to dry, this binder becomes “tacky”
or “sticky”. While in this stage of the drying process, the tack on the dies will tend to pick up both airborne dust and
any dust or dirt on the surface of the material being printed. When this happens, the dies should be cleaned or
replaced. The easiest method of cleaning the dies requires the appropriate solvent for the ink being used, a pair of
rubber gloves, safety glasses, an apron to protect your clothing is recommended, a toothbrush, some clean paper
towels and a plastic bag to protect your workbench from staining. (Naturally, the toothbrush will never be suitable
for oral hygiene use after this process.)
After some period of use, the accumulation of contaminates on the dies will cause degradation of the print quality;
cleaning the printing dies, excluding excessive wear to the die face, will restore the print quality of the printer.
