But in following the PNP directions, I have been unable to get the
design to adhere to the metal, despite following its directions --
cleaning metal with steel wool and rinsing with soap and water. I
have been measuring the temperature of the iron between 275 and 325
and varying the time between a minute and five minutes and the
resist just WILL NOT STICK. The sheets were printed from my in-house
Brother Laser Printer which I bought for the job for about $100.
My research on using PnP blue when I was getting ready to start using
it took me to a lot of circuit board forums, since those folks use
PnP all the time. In more than one place people complained about
Brother copiers/printers not working well with it. In fact, one of
the online vendors of PnP - Techniks.com - actually has posted on its
site that they have been receiving reports that PnP is not working
well with later model Brother laser printers and copiers. (Must be
something about the toner?)
They are at www.techniks.com, in case you want to take a look.
Your Brother printer may not be the problem, but then again…
Assuming you are still having difficulties despite addressing the
issues raised by other posters - I would definitely try running the
PnP on another toner-based copier, just to be sure it isn’t the
toner used by Brother.
I will say I have never used PnP on gold - only copper, brass and
silver - so don’t know how that affects adherence at all. Still, it
would not hurt to try it on another copier, just to be sure you’re
not driving yourself insane unnecessarily!
