Ink information links (esp. lubricating)
One that addresses my Qs about what water based lubes (other than KY
grin) are made of: http://pffc-online.com/mag/paper_rol...es_waterbased/ A typical ink formulation will contain lubricants that provide rub and mar resistance, as well as a low COF to the ink film. The level of these lubricants in an ink can vary depending on the process and end-use requirements. Laminating inks do not utilize lubricants, since the lamination bonds could be affected. Among the common lubricants used in inks are PE and PP waxes, silicones, fatty acid amides, and fluorocarbon waxes such as tetrafluoroethylene (PTFE). These lubricants differ greatly in their effectiveness, rate of migration, and temperature resistance. PTFE waxes provide very high temperature resistance as well as rub and low COF, but they are more expensive. Typically, the ink formulator will use several of these lubricants in a given ink formula to optimize ink lubricity. Eventually there may be an MSDS for American Eel ink which would resolve some of the mystery surrounding it.
