What I really want is something that is really opaque, not sorta see through.
Plastisol ink.
Wilflex MP formula ( I believe that's 'multi-purpose', but I've never actually heard what it designated ).
Nice opacity.
The only downside is the PC ( their designation ) mixing system uses too many pigments.
GNS inks use the same calcs for mixing, just different bases.
They've since changed the name. Used to be MP base.
They now call it 'amazing base'...which is kinda funny, but, it is a good base...don't know about amazing..
I've used it for over 10 years, and it still gets the job done on all sorts of substrates.
Use a white polymax base if you're printing on that sort of sh..stuff.
.02 for the post.
Cheers.
