Durabright (Ultra) type inks

Durabright (Ultra) type inks

2007-02-13 by Herbert E. Plett

>> the ink I tried is from Oliser and Pigmented, as for the canon OEM black

>You might try:
>http://www.inknstuff.com

Thanks for the tip.
There I found a very interesting article about pigmented inks, really worth to
take a look at! (specially at the end)
http://inkcityusa.com/epson_durabrite_inks.htm

Seems there is no reason a Canon, Lexmark or HP cannot use pigmented inks. It's
just a matter of getting the right one...
Canon uses the black pigmented anyway. How could the printer tell if it's
another color?
The trick may be the other ingredients (like carrier, fixer, etc) when 'cured'.
Perhaps it is the actual yellow or magenta 'powder' in the ink that fuses and
sticks to the copper. Black is carbon that doesn't fuse or stick by itself to
the copper when heated, and the rest of ingredients are soluble. That would
explain why Durabright black has been useless till now.

interesting to follow up...

This might be a little bit off the wall, bit I wonder if it would be 
possible to make an printable etch resist by mixing laser printer toner 
with a fluid carrier (most ink is an alcohol/water mix, right)?

You would probably have to use it in a epson printer, as I could see 
some issues coming from the toner possible melting in a thermal print 
head, but if I think toner is fine enough to not clog the print head.

If someone has a bunch of old junk epson printers, you could try it.

Toner dissolves nicely in acetone, so as long as acetone won't dissolve
any parts between the tank and the nozzle, you could be in business.

This needs to be nipped in the bud before there are more damaged 
printers. Don't even try permanent marker ink in an Inkjet printer much 
less some concoction that will surely attack plastic.

I second your opinion. I've heard some pretty unlikely ideas, but putting  
toner into an inkjet must be pretty high on the list.

Awww, let the kids have their fun. I can't wait for the photos!

As tempting as it may be, the physics of inkjet heads and the chemistry 
of inkjet ink is beyond the reach of regular consumers. Viscosity, 
Particle size, wetting / drying times are critical.

The closest thing done was using melted wax droplets and a cnc type 
machine, but the resolution was limitied.

Let's just get the procedure down for using regular pigmented ink 
reliably.

thanks, someone had to do that!
for me, getting ink overseas just for test is not reasonable... and I have no
eBay to get disposable printers either.

Ok. It appears that pigment inks are needed. Let's start a list. 

Which printers use or can use Pigment inks?
   1. Epson

What other pigment inks are availible? 
   1.  Durabrite
   2.  MISPRO

Gents, is it possible to start a list or a "Wikidirectprinter Hacks" kinda deal that members can add there experiences as to what works and doesn't work ....  Printer , Ink used, Temps for curing, comments and  results with a few pic's.

At least 3 were started.
<http://techref.massmind.org/techref/pcb/etch/directinkjetresist.htm>

I started another <http://dipcb.schtuff.com/>, which has only ever seen  
use to upload some pictures, i have no time or inclination at this moment  
to work on it, you are welcome to ownership if you are offering.

There's also the one Phil made  
<http://pcbwiki.philpem.me.uk/wiki/Main_Page>

As you can see, James is the only one who actually put work into it and  
made something. Several people have come to inkjet development via his  
page, it's great he put the information up.

All the other stuff (including from myself) is just hot air, starting a  
wiki is easy finding time to maintain one is not. It has been suggested to  
use a wiki a hundred times on this list, for various topics, never once  
did something really grand come from it, as far as i know. Nobody is  
prepared to put his time where his mouth is, and i can well understand  
that.

Just forget it, and read everything you can right here on this list, which  
is _THE_ place where this information is shared. Or if you really want to  
work on a Wiki, ask James his seems most promising. You are also welcome  
to mine (although i believe the host is not all that practical), and I'm  
sure Phil would welcome you to write articles on his space too.

I don't think a wiki is really all that helpful, it only shows "one  
version" of the facts, and is hard to keep up to date. Here you get all  
the data and can ask for clarification too, it's really as good as it  
gets. In a way i even prefer if there is no wiki, since it means all the  
info is coming through here and i don't have to keep up with some other  
place as well.

FWIW, I came across another somewhat lengthy thread on this in the most

Yes, and if they'd gone here instead they'd not have wasted time, like  
with the black ink for example.
It works the other way around too, if they'd discovered something useful  
we wouldn't necessarily know, at least right away.
Better to keep all the stuff in one place, especially when there is only a  
handful of people doing the same thing. But you can't force people.

Hi, my name is Russell, I started the thread on the printer mod in 
CNCzone.  For what it it worth, I did come here first and I didn't 
realize I was wasting my time, sorry bout that.  I got the 
inspiration from James's site and decided to post a log on CNCzone, 
as I thought others might benifit.  I like the forum format as I find 
it more organized and easier to get the info I need, each to their 
own.

Not sure what you mean by the black ink example, I know one of the 
guys tried it as a resist, even though magenta seems to be better by 
all accounts, but people will experiment...

I am getting the hang of this group's format, and sorry if my first 
post is a little negative, I think what you guys are achieving is 
awesome, I am all for getting helpful info to whoever wants to learn, 
that is my motivation in logging my printer mod attempt.  Wasn't 
thinking of an "us and them" scenario.

Russell.

There are pros and cons. No doubt Microsoft's efforts to "assimilate" 
the competition in "Borg fashion" stems from the same line of thinking.

Hi Russ,

I just finished reading the entire thread on CNCzone.  I am a member of 
CNCzone and somehow missed it, the first time around..

Great Work! A must read for anyone planning a conversion. You don't 
seem to have the problems with puddling / curing / etching that others 
are plagued with.

I wouldn't worry too much about Stefie's comments, though. You stole a 
little bit of his thunder with the posting, He was the first (sort of) 
here that made it work. Just don't start a thread about chicken grill 
motors. ;)

One of the things that most impressed me about the Cnczone members is 
that they left their egos at home. We have about six "experts" here.

Please continue to post here and ignore any of the forthcoming sniping.

I'd like it if you'd not make false allegations, and i'd also like if you  
could try to remember that Volkan was the first one making it work. But i  
know you have trouble even remembering his name. - back to ignoring you.

And, this is precisely the kind of stuff that turns new people to this 
list completely off.

I've unsubscribed other lists before because I can't handle the amount 
of negativity introduced by self professed experts and folks who just 
can't take a joke, this obviously was, or did you not see the smiley.

You can't possibly _harm_ the development of this process in any way if  
you take it to a dozen other places, since it is just additional people  
doing additional work getting additional results. This can only further  
the development of direct inkjet printing, which is the only thing i am  
interested in becasue i want to use it at some point for all my PCBs. I  
want as many people to work on it and use it as possible, because then we  
will get results. At the moment i had to freeze my efforts, but as i had  
hoped other people are getting on with it and i will have a great  
advantage from that when i get back to it. It is obvious that i can only  
benefit from any additional efforts by other people, and silly allegations  
by some folks don't even make any sense.

But what i'm saying is that we could benefit more from each other more if  
we all discussed it in one place, immediately sharing what we find out.  
There is no harm in making mistakes twice, individually, but there is also  
no real benefit from it. And "chance" discoveries are very tricky to  
repeat. If you look back in history most interesting developments have  
been worked on simultaneously, and perfected, by two or more totally  
independent individuals or groups. They just never knew ;-). I see no  
reason for that. It will be a lot better in this case since you read stuff  
here, and i'm sure if you find something important out you'll tell us, but  
i can't quite see the advantage of two places of discussion. I can  
understand why you like the forum better (i like the mailgroup better  
probably for much the same reasons just reversed), so if that is worth the  
fragmentation of information for you that's fine with me. Just let us know  
too if you find out something important ;-)

As to the black ink, yes, experimentation is always good (we'd have  
nothing without it), but as far as i'm aware everyone has found black to  
be just about the worst resist, so it makes it unnecessary hard to start  
with, maybe impossible.

Anyway, if i come across a bit grumpy, well, that's probably because i am  
like that most of the time. I'm lazy, and still want to make the best PCBs  
possible, so i'd love for other people to do all the development work for  
me, and that's much easier if they are all here putting that information  
right into my mailbox ;-). I'm only afraid i'll miss something, you  
mustn't be offended, ok?

You also find that often, one of the individuals had a very strong 
personality, savaged others, and tried to get their point of view 
across.  Often, technical excellence is not the goal.

I can think of no finer examples than Thomas Edison vs. Nikola Tesla and 
Bill Gates vs. the world.  In the former case, nearly by sheer luck, 
technical excellence won out.  In the latter, clearly it did not.

I have the _very same_ here, that's why i put inkjet aside for a while and  
fetched the fuser from the attic where i'd just stored it expecting no  
further need.

The strange thing is i disabled the cleaning vacuum pump (took away the  
gear and plugged the end of the hose with a syringe). After disabling it,  
i used the printer for some months, and it would work just perfect on all  
nozzles without any cleaning, or only very little cleaning (just draw a  
little on the syringe). I know i left it several weeks in a row without  
any use, and it would print perfect immediately after.

But then, suddenly one day, it did not print on all nozzles, and no matter  
what i tried it would not clean out. When i got it initially it was also  
clogged (and the vacuum hose was blocked by gummed up ink). Back then it  
was very easy to clean, using Steve's solution, put it on the parking pad  
and let the head stew there overnight, next day it cleaned just fine with  
a little suction on the vacuum. But now there is no positive effect when i  
do that.

I don't have that much ink left, so i don't want to waste much of it in  
cleaning attempts. I'll probably just get another printer (that one was  
only 1eur). I might also empty the carts and fill them with cleaning fluid  
to have another go.

I don't know why it suddenly acted up, especially since it worked before  
with no or virtually no cleaning at all.
One option could be that some debris or fiber got onto the parking pad,  
breaking the seal. Steve said that will kill it. May also be something  
else i don't know.

About the heat possibly drying the ink in the head, i was wondering about  
it, but if that's a probem shouldn't it show immediately?

So you see, it could be your printer is just uncooperative like mine, and  
it has nothing to do with the heat. I guess if we see them clogging all  
the time with heated boards we know for sure.

Did it stop during printing, or while standing idle? I guess that could  
tell us something regarding the heat issue.

Clogged over night, not all the way but got worse as I tried to clean it out. I used the regular
clean, the SSC power clean and using the syringe at the end of the drain hose. It hardly prints at
all now. Cleaning solution in the carts may be the next step. Maybe these print heads with the
small nozzles are not the best. We need more testing with other printers. Everbody get a printer
and get to work.

But it worked for months, at least mine did. I don't see at all why it  
would suddenly fail.
Mine also got worse as i tried cleaning instead of better.

I wonder what i need to swap out if i get a new printer, i expect both the  
head and the controller board. I don't necessarily want to mechanically  
modify another printer (just yet, at some point i'll probably want to make  
a better version).


Has anyone tried what maximum weight the paper feed can carry? (how heavy  
the carrier can be i mean). There is also a calibration parameter that has  
to do with that, i think.

I have three kids, you will have to do better than that to offend 
me :P

We have similiar goals, to make the best possible PCB's at home, so 
lets just focus on that.  My build log on CNCzone is just that, 
documentation of what I am doing, I am not doing anything out of the 
ordinary, just following in your footsteps.  Be sure if I stumble 
across anything I will post the info both here and on CNCzone.

The guys on CNCzone are a great bunch, and insanely clever (I just 
have the insane part:)  a couple of them are interested in helping, 
not because they want to make PCB's but they like the challenge, they 
may not find anything helpful, but they will try.

But enough of that, back to the serious stuff, Myc, the reason I 
haven't had any problems with clogging etc. is that I haven't tried 
to print onto copper yet, the only prints I have done are with black 
ink to test the printer and card carrier, it is a work in progress...

My next move is to make a chip resetter as per the SSC utility 
schematic's, (thanks Bill!) I have just recieved a commercial version 
today, but the SSC version will give me more control.  I will draw up 
a schematic tonight and convert to g-code ready to route with my CNC 
router tomorrow morning.  Then its onto some serious testing on 
copper.

My nephew is a chemical engineer and if it would be useful I can ask 
him to look into the print head clogging issue, might be worth a try, 
he loves fishing so I can bribe him with a reef fishing trip to hurry 
him a little ;)

Cheers.

Russell.

DYEBASE printers??  aren't Cannon, Lexmark, HP, etc. just dyebase printers?
This sounds really promising to verify.
Somebody with a 'head on cartridge' type (Canon BC20 black) printer willing to
test?

I have an old Canon S200Spx that I flushed out the old dye and replaced it 
with a local refill ink from Oliser here in Indonesia,
it prints just as good if not better.
I just gotta get the time and a few parts to tweak the undercarriage of this 
printer to handle the PCB.

I have used a homemade resetter circuit for a while, i took all the chips  
 from the carts, soldered them together, and split off the part of the  
ribbon cable with the right signals to keep them stationary. This way i  
could reset them all at once, without pulling a cart (and introducing air).

But i must say it wasn't worth the effort, i bought new spongeless carts  
with auto reset chips for some irish outfit for no money at all, i believe  
they were cheaper with the chips than the carts alone from mispro. The  
auto reset is great it's like the silly chip never existed.

Anyway, just in case you get tired of the resetting, those auto reset  
chips are great, and do not have to cost the kings ransom mispro asks. I  
could probably find out the link of the supplier again, if ireland is an  
option (shipping within the EU was not expensive, don't remember  
worldwide).

I tried the heat transfer yellow about a week or so ago. Posted the
results but used MIS stock or item numbers. The results were not good
just a partial resist. However , these tests were run in unison with
the magenta tests and that didnt work satisfactory, for me, either.
The MIS HT yellow might work under different conditions. I have yet to
find any ink that resists as well as MISPRO yellow. This with the
conditions we are using 230-240 C cure etc. Just finished my feed mods
to the Epson printer and am ready to try some more boards now. These
tests will be done with preheat. Not sure yet heated air or infrared
on the board before feeding into or as it is fed into the the Printer.
However would like to be able to measure the heat to know about what
the infeed temp is. I have a IR heat probe and perhaps I can play that
on the surface next to the board. We will see.
