Electronic – PCB layout toner transfer – ink printer

pcbpcb-fabrication

I use iron to transfer toner to the copper board, and have been using laser printer. I saw some discussion on the net that it is also possible to use use ink printer if the ink is a good quality. I have a HP inkjet printer and use original cartridges. Could someone explain if (how) it is possible to use the ink on the toner transfer?

What you can do with an ink printer is to produce a mask by printing onto a transparent (ink compatible) sheet. This is then used to control the exposure of photo sensitized board under a UV light.

Laser toner works as a transfer method because the 'ink' is actually a thermo-plastic (i.e. not 'ink' as in the inkjet) that can be re-heated with an iron and made to stick onto the copper surface as a resist.
