Hello,

For SolderMask with Inkjet printer, you can see form Printar
http://www.all4-pcb.us/printar.htm

The ink for solder mask is appromatevely the same for nomenclature
just the color green or white.

But the viscosity is so so so hight, you can turn the pot and the ink
not go out, very big marmelade, i think no possibility to put in
inkjet cartridje

Special ink for solderMask, is necessacery go to 250° centigrade, for
resist solder and automatik solder machine, reflow.

Also, special ink for solder mask by "LACKWERK PETERS"
http://www.peters.de/index_e.htm

ELPEMER photoimageable is a nice system 2467 pack, but in 2 component.
Developement in sodic soap.

For dry film solder mask: CONFORMASK by SHIPLEY
http://www.pcb-pool.com/download/spezifikation/eng_ConforMask_2500_
(englisch).pdf
Developement in sodic soap.

Very nice process, vacum system not necesary for amateur application,
just laminate, UV insolation and develop.

For copy film, also from SHIPLEY, "DIAZO-FILM", just copy transparent
film from for lazer printed and copy with UV contact chassi.
Developpement in amonia vapor soap the same from architechture copy
plant.

You have a orange transparency film, you can place and see your pad
to adjust position film and make UV exposur; very strong film.
