colouring PCB's

[James]

I am making some pcb's using FR4 boards and wanted to color them before
screen printing. This is just a hobby run of a few boards but I wanted them
black. Has anyone ever or seen reference to say die or vinyl dye being used?

Thanks,

a fairly safe way to color a pcb is to spray using a polyurethane
coating and then any color you want on top of it..pcbds are often
surface protected with a clear coat of polyurethane..u can also try an
acrylic conformal coat which is solvent removable..look up Humiseal
co. in Queens NY aand ask them the same question..

We've done black solder resist before now.
