Digital BW, The Print

A bit of a weird one.

Back when I used Epson printers I used to print a copyright and contact 
details stamp on the reverse of the paper in pale gray. At that time I was 
running a printer with Piezotones and this worked fine with most papers 
and there was no print through.

I now use HP B9180 and it won't work. The printer mechanism is more 
ferocious and sometimes marks the print surface of most paper types when 
fed upside down. I've had to revert to a rubber stamp.

However I'm mistrustful of inks for rubber stamps. All I seem to be able 
to find are office inks in black, blue, red, green or violet. They are 
either water-based (no idea how permanent or whether long-term damage may 
be an issue), or spirit based "permanent" inks. Ditto, plus the latter 
certainly take alright on all papers I've tried them with, but there is a 
serious problem of print-through, even on heavy papers like Hahn. PR 308.

I want light gray archival rubber stamp ink, that won't penetrate the 
paper base and will dry OK on either coated or uncoated papers.

Years ago I had to switch to permanent ink for stamping resin-coated 
bromides (water-based never dried), but didn't then have the print-through 
problems I am getting with uncoated papers.

Any ideas anyone? Any chance any of the DIY formulations used by this 
group might be usable?

Alternatively, what do other people do?
