[comp.sys.amiga.graphics] Deskjet Inkmun Full Color Kit?

robinson@star.enet.dec.com (04/03/91)

In the May '91 issue of Amiga World "GO AMIGA" advertises:

  "Deskjet Full Color

   Print full color on your HP Deskjet printer!
   Inkmun Full Color Kit.......$34.95"

Does anyone know about this? How does it work and what
software would I need to take advantage of it?
I'm considering a used Paintjet for around $600 and wonder
how this new (?) development affects that consideration.

thanks,

   It isn't much of a big deal.  It is just a kit that allows you to 
clean empty DeskJet ink cartridges and refill them with colored ink.
The only program that I know of that will allow you to use these 
colored inks is PageStream.  You can't use the Preferences printer,
for instance, because you have to produce a color seperated output;
IE: feed the paper back in three times, once for each color.

   This will in no way obsolete the PaintJet, because the PaintJet 
will still produce results that are just as good (if not better) with
a single printing of the page.  If you only want to produce a very
occasional colored printout, look at this kit.  If you are going to
be printing a lot of color printouts, I recommend a true color printer
like the PaintJet.

Seems like any wordprocessor could be used with the Inkum if you just wanted
your letter to be printed in all one color.
PageStream is one program that will produce 4 color separations for printing
but there are other desktip publishing packages that will do this also.
One possible advantage is the DeskJet 500 is advertised as a 300 dpi printer
vs 180 dpi for the PaintJet. This resolution advantage may be negated by
paper positioning error in the 2nd and 3rd pass for the other colors.

It's been known for quite a while that Deskjet cartridges can be reinked (in
brief, you use a chef's syringe and Sheaffer Jet Black Skrip ink). This kit
provides red, yellow, and blue inks for you to use in used DJ cartridges,
and then you can use something like Professional Page or Pagestream, which
do IFF color separation, to print it out. It's a laborious process, but you
do get pretty nice results...

Thing about the DeskJet - it can do 300dpi (dots per inch) at its highest 
print density.  The PaintJet can only do 180dpi.  So, you'd actually be 
getting BETTER resolution as well as color with this DeskJet/Inkmun 
combo.  Mind you, the colors wouldn't be dithered so much as layered upon 
each other, which may cause discrepancies between screen and printer (or 
rather, more discrepancies than what you ALREADY get...).
 
Also, doesn't Professional Page by Gold Disk do color separations?  Not 
that PageStream isn't perfectly suitable - I use it on both a DeskJet and 
PaintJet and love it.  (No InkMun, though.)

	Not sure about this... but it PROBABLY means 3 different ink
	cartridges... and somehow dithering the image together in the
	Deskjet using three diferent passes.... or worse, that it only
	provides different color inks, and it's up to you on how to 
	get them on to the page in a meaningful manner.

How well does this actually work?  I don't think the registration on my DeskJet
is good enough to get anything but a colored blur out of this.  If it's 
actually OK, I might give it a try...

I've got a few questions I hope someone can answer about this process:

1. Isn't getting good print registration between the three passes almost 
   impossible?

2. Does the ink come prefilled into cartridges so that you can just snap
   one out and the next one in, or do I need to start saving empties?
   
3. How much ink is provided.  Is it as much as is in a standard cartridge?

speaking of the paintjet (which i love dearly), a friend of mine who is
in the 'computer biz' as they say, recently went to one of those industry
shows where everyone and their shadow was showing off new toys.. hp was
there, demoing the new colour inks.. he brought home 2 printed pages and
i was rather stunned at the differences.. these inks look like something
from the offset industry. i have called around and it seems no on knows
anything about them.. has anyone found a supplier yet? from what i understand
the new inks are clearly marked on the box as new and improved, and the cost is
the same as the old inks. i want i want iwant iwant.....

The Deskjet has pretty good paper handling, all things considered. I think
it would work.

Nope, you have to save empties. Getting all the black ink out of them is
time-consuming, as well, but it can be done (or at least MOST of the black
ink...)

> 3. How much ink is provided.  Is it as much as is in a standard cartridge?
It takes about 15 ml to fill a cartridge, or about 0.5 oz. A couple years
back, a fellow in INFO wrote about how he had used food coloring in his
Xerox 4020 with great results. Might be worth a try...

I've seen the output from Inkmun inks.  The kit is pretty neat, but it is
NO SUBSTITUTE for a paintjet.  If you look at the sample output they give,
all their text uses a primary ink color--no color mixing is done.  If you
look at some of the printed pictures, you can see why:  The registration
is horrible.  Anyone with a deskjet knows how poor the paper mechanism is.
There's no way it can be repeatable enough to do general-purpose color
printing.

BTW, the inkmun inks work horribly as replacement ink for a paintjet.  It's
viscosity seems to be wrong or something, as it prints erratically.
