Why most ink cartridges have just yellow & no green ink ?

[TE Cheah]

My Canon iP1880 can't print dark green, just pale green.
I'll put green ink into cartridge. Has any1 here done this ?

Because the printer manufactures as well as artists have figured that they
can't build a printer large enough to hold 256,000 ink cartridges, the
artists are not strong enough to carry 256,000 bottle of paint colors. So
they come up with the option to mix few basic colors to whatever color they
want.

IOW, Canon manufacture ships you the Canon iP1880 printer + few ink
cartridges + a Professional of Color Mixter along with the printer.

Judging by the trend to smaller and smaller capacity OEM ink cartidges (with
higher prices) almost every year.
I'd say soon the printer companies just may be able achieve that goal soon.

Of course each of the cartridges will cost $20.00 to replace, have special
chips that explode if you even think about trying to refill them, and if one
color is empty the whole printer locks up, until you replace the empty one.

But on the bright side you will get the whole printer new for $3.00.

It depends on what manufacture and model you have. There are refillable
ink cartrigge with ARC (Auto Reset Chip) for many models, and there are
remanufactured ink cartridge (refilled from original cartridges with chip
reset).

Refillable Ink Cartridges is around $20-120 for 6 cartridge set. The
cartridge and chip are same but some company charge more/less.

6 ink bottles is around $20-80 depending on what company you buy the ink.

Over a year ago, I paid $45 for both cartridges + Ink, and $20 for 6
emptied catridges from different company. And I just ordered 6 bottles of
ink for $19.xx

I dare you to tell me what printer manufacturer, offers O.E.M. refillable
cartidges

They all do their best to make sure any aftermarket ink can never work.
Many "new models" take about 6 months+ before you can get any aftermaket
ink supplies or the re-setters.

And WHY do we even need re-setters if the printer companies allowed us to
refill in the first place.

 

[TE Cheah]

Your printer has a color map that adds other colors to give you a specific

green color.

Green is a pure colour, no other colour added can increase pale green
to darker green.

If you put green ink into a yellow cartridge, you have no way of telling
your printer that you've done this.

If a printout has too many green pixels, 1 can use software to reduce
image's green content, before printing.

You will NOT get a green output.

I think I will, but may need to swap between 2 different cartridges ( 1
has yellow ink ) if reducing green content can't work well.

Well, if you DARE then there will be no DARE from me as I have no interest
in daring game.

You sounds mistaken with MOVIE or something. Unlike movie marketing,
printer manufacture don't have time to mess around with the Chip Protection
often. So some do but not all

And WHY do we even need re-setters if the printer companies allowed us to
refill in the first place.

And are you talking about ALL models or SOME model? I have been using ink
jet printer for so long, gone through several Chip Resetters and generations
of printers so I do know the general.

Green is a pure colour, no other colour added can increase pale green
to darker green.

Green IS a "pure color" when it comes to light. With light, you mix red
and green to get yellow.

Green is NOT a "pure color" when it comes to ink. With ink, green is
obtained by mixing cyan and yellow, for the most part.

If a printout has too many green pixels, 1 can use software to reduce
image's green content, before printing.

I think I will, but may need to swap between 2 different cartridges ( 1
has yellow ink ) if reducing green content can't work well.

If you put green into a yellow cartridge, at best all you do is ruin a
perfectly good yellow cartridge.

I just saw this reply in another post.
It doesn't blow up/explode yet, but they are getting closer <g>

"There is no way to reset a 9-pin Epson chip with a 7-pin resetter. You
can order a 9-pin resetter from supplysource(at)gmail.com
The 9-pin resetter is capable of resetting 7-pin cartridges as well.
Please note that Epson has added a "fuse" that blows out when if the
ink level drops below about 10% to the 9-pin cartridges. So it is
important to refill before the ink level gets too low. Once the fuse
blows the cartridge becomes useless.

I don't read or have all the responses to this threat to know what the
9-pin, 7-pin or whatever pin resetter. But I can say this much

- Different Chip Resetter works with different catridge.

- ACR = Auto Chip Resetter which is not a standalone Chip Resetter but a
small circuit board to replace the original ink counter and protection Epson
and other printer manufactures have on their ink catridges.

- The special REFILLABLE ink catridge is a special designed catridge to
replace the OEM cartridge. Same with the CIS it often come with the ACR
(Auto Chip Resetter), and different version of ACR may work differently.

Or some earlier developement may have to manually reset (some CIS has
built-in a BUTTON for owner to PUSH), some newer version may work better on
newer version of protection.

- Some newer protection catridge of Epson not only have dual CHIPs (2
circuit boards) but also doubled-case (the inner and outer case). So you
are right about the 10% blow up (but not with the refillable ink catridge
with ACR), and if you DRILL then you may need to know WHERE to drill as well
as how far you can drill.

The blue ink in my cartridge does not look like cyan ( a mix of
green & blue ). I notice my cartridege can print light green
despite having just red blue & yellow ink, seems strange.
Are you a professional printer ?

Nope. I'm a farmer by trade, but I happen to have an electrical
engineering degree.

The colors on a light-emitting device like a CRT TV/monitor screen are
produced by mixing various levels of red, green, and blue (RGB). This is
called *additive* color mixing, because the emitted lights are *added*
together. With that system, adding all basic colors together produces white.

Inks and pigments on the other hand, use *subtractive* coloring. They
get their displayed colors by reflecting a portion of the light that
reaches them, and *subtracting* the rest through absorption. The basic
subtractive colors are Cyan, Magenta, and Yellow. (CMYK. The "K" stands
for the "key," which is black.) Mix those three together and you get
black, because all reflected colors are *subtracted*.

That's the basics. In practice, printed colors are enhanced by mixing in
varying amounts of black, and in six-color photo printers, the colors
are enhanced through the use of additional amounts of light cyan and
light magenta. The exact details vary with the printer, and are beyond
my expertise.

I don't know of any consumer printer that uses green ink, but then I've
been wrong before.

For more detailed explanations, I suggest you Google CMYK. Wikipedia has
a pretty good article on it.

subtractive colors are Cyan, Magenta, and Yellow

Have you noticed that the cyan ink of probably every brand
looks like just blue ( with no green content ) ? Even the 1st
cyan colour in wikipedia page on CMYK
http://en.wikipedia.org/wiki/CMYK_color_model
looks just blue.
I may add green ink into a "cyan" ink, to get greener printouts.

I think you might do better to adjust the colour balance of your picture.

People see colour differently. Produce a colour print with perfect
matching, excellent workflow, precision printing: hang it in a gallery
under perfect lighting, and 10,000 people see 10,000 slightly different
pictures. The vast majority see something very close to what the
photographer intended, but not all

As you seem to have a problem that is unique to you, perhaps you should
check that you are not "optically different". Red-green colour
blindness is common, but other more subtle differences do exist.

I think the view of this forum is that the existing colour print process
and inks are fine for most of us.
