Ink information links (esp. lubricating)

One that addresses my Qs about what water based lubes (other than KY
grin) are made of:

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.
