does anyone knows how to increase the surface energy of a silkscreen surface? not increase the surface tension of the ink, but to increase the surface
energy of the painted surface after the paint has been cured..
i can get about 36dynes/cm now and i want to increase it to 40dynes/cm..
the strange thing is that the surface energy really varies alot through different batches of paint.. i am also wondering if this is natural.. and if
there is any way to stabilize it.
the only method i have to increase the surface energy of the surface is by cleaning it with ethanol.. it will increase the surface energy to
~40dynes/cm.. but its only temporary.. after a few days it will drop again..
would appreciate any help i can get!!
thanks a million!

Perhaps add something like Arabic gum or some of the other "gums" out there.

The only thing I can figure out is that you're having an adhesion problem with your pigment!
We don't know what type of surface you're printing onto, or the type of paint/pigment being used.
There are a number of ways to increase surface energy but some are surface specific.
