Is the problem with your inks the PRICE?  Or that they dont work on 
copper?

ye man maybe both

i am waiting for it to dry overnight  
{second attempt with claria inks{default ones}}

then brown it off  
still dont hold out much hope 
if it doesnt work  ill order some mis-pro for now... 
the cost is'nt an issue just  finding it in the uk

According to what I read - even with the mis-pro inks, you must wrestle 
with the pcb being heated entirely to the exact temprature in order to 
seal the ink.

i think this is the fusing tempreture???
i would  ask the maker of the ink???? dont know who has ???

i agree the hold and hope method is a little flaw i see too

i did plan to use an aneling oven next 
once i get the inks i have a small unit for castings
maybe try to reuse 
some sort of old thermo controlled sandwitch toaster or something ...

i think this ink works when heated in a similar fashion to toner
i think  its a plstic ploimer ink  so will do the same thing only in 
toner
copiers this gets fused after fixed up
this fusing stage is around 200-300deg or more 
my old HP had a label beware 350degrees  so ????
all to find out for us inkys

I see what your talking about now.  A new R220 or R260 (AS WITH ALL) 
epson printers new, come with SAMPLE cartridges that allow only a few 
pages to print.

So a new printer with new cartridges comes out to around $200, which is 
kinda pricey.

Epson's Claria inks are dye inks, not pigmented inks. That is most
likely the problem.

I think you are confusing laser and inkjet. This thread is about
inkjet direct printing. Since it is not meant to be used this way, the
maker of the ink will be no help with heating of the ink.

Thats why I gave up.

Sticking with my trusty plotter, an elastic band and a pen for now.

Epson makes large wide-format printers used for printing signs on 
canvas or plastic vynil for trucks, cars and airplanes.  There is a 
heating element built into the output rail to warm-up the ink printed 
on the material, to seal it.  I wonder if using that ink would make a 
difference?

What pens are you using that makes trusty results?

I wonder if using that printer is the answer...........

Lol, if your pcb's need to be three feet wide and 6 feet long?  Maybe.  
Otherwise, I feel they probably use the same head technology as they do 
in their desktop printers.  It would just be a matter of getting sample 
ink for testing in a desktop printer - to buy the cartridge for a 1-
time test would be too costly.

It isn't just that, also keep in mind that an initial ink charge must
purge the heads of all air and whatever fluid they put in it when
manufactured. So not only fill the print heads, but pull enough ink
through to hopefully clear all air or storage fluid out.

This related to why, if you are changing one color that is out, you
might as well change any others that are nearly out at the same time.
Because it can't purge one color, it purges them all.

Do You know what the storage fluid is?
When i get back to inkjet i may want to purchase several printers and  
store them.

I suspect it would be something like glycerine or glycol?
