Default How to set ICC profile?

hallo,

- I'm with:
HP officejet 6830 pro
Windows 10 Home

- my aim:
save black ink

- how accomplish that:
I think (if I'm not wrong...)
it could be accomplished
by using an icc profile (edited by me)
where I substitute the 'black' color with a 'dark grey' color
and then
by telling the printer to use this icc profile,
so the printer will never print blak
and will always print dark grey

- answer:
is this method correct?
(if it is correct, I will ask you few questions
on how to tell my printer to use this new icc profile)

Is it possible to just remove the black cartridge that the printer would
not cease working?


Mmmhh... I don't know,
but even if it will work,
it will not be the solution I like,
because black cartridge is less expensive
than color cartridge.

So I prefer buy and use the black cartrige, and,
instead of printing "black" color,
I 'd like to print "dark grey"...

This need it expecially occours
when opening and printing .pdf file
by using the "Acrobat Reader free" software
because there is non tool to brighten the pages
(so I have to convert the pdf file pages
into several jpg images, then brighten them with a graphic software
and then print them; but it is boring...).

So I think that the best solution is to force
the printer to use an icc color profile
where the 'black' color doesn't exists
and does exists a 'dark grey' color instead.

[...]

Not using Windows but Linux, the print system relies on the CUPS print
server. There I can tell the printer to use monochrome. Won't test it
(almost out of ink as well as of paper), thus cannot tell if it would use
the b/w cartridge or compose the printout using the color cartridges to
produce gray scale.

So it might depend on what the driver decides which cartridges to use if
monochrome is selected.

Check your driver options and set it to monochrome. If it still uses the
b/w cartridge, you're out of luck. Unless the printer doesn't refuse to
print if you physically remove the black cartridge.


I noted this:

when the black ink has finished (empty),
the printer uses the three color inks to "imitate" the black color

the printer itself warns and asks:
"The black ink is over, do you want to use the color inks
to keep on printing?"
I say 'yes' and the printer keeps on printing,
with good result (I have a paper with a dark grey or a dark brown
instead of black, but it is acceptable)

Have you thought of using a Print manager software, FinePrint is an
example but I'm sure if you hunt around there are others. Just reducing
K may alter all your other printed colours in ways you dont expect! C+


'Fine print' doesn't allow to reduce the 'quantity' of ink ('saturation' or
'lightness' of the black color...).
And actually I don't know any printer manager (free) that is able to do
this... If you know I'll give a try.

But trying to edit and install an icc file
is very interesting to me... :

I saw from Windows 10 'Control Panel''Color Manager'
that my HP printer uses two .icc files
(one for Black&White and another for Color).

I duplicated the Color file, opened it with an editor called 'Delcotec'
and tried to change what I think is the black value.
Then saved the new .icc file and installed it in Windows 10.

Then from the Windows 10 'Color Manager' panel
I told the HP printer to use this new .icc file (telling it is the default
profile now),
I printed a testing page but nothing has changed :-( .

Note:
I also duplicated the Black&White icc file
and tried to edit it,
but I was not able to find and change the black value.

Sorry I cant help much - and moved to laser printing years ago!
Would the old InkSaver software I remember from 15-20 years ago get you
anywhere? I think that allowed you to manipulate the separate ink
colours. C+


I searched...
I tried InkSaver, it installs on windows 10 but when lounched it hangs.

I tried GreenCloud... it installs very well and it does what it promises:
among the other features it has three setting levels to reduce the ink
(black or color) you are going to print, and they work; tried a couple of
pages... not bad till now.
But the full version is 19.00 USD

I think I'll try FinePrint you suggested, just for a comparision.
The descrition on its web site tells it has three setting levels to reduce
the ink too.
It is not freeware.

If anyone knows similar software he can suggest too,
but as far I have seen, there are not so many software
(for Widows 10 and able to reduce the ink level before printing,
and maybe free...)

I'm also waiting for Andreas to explain the method he pointed out
(Andreas are you suggesting me to use only the color cartridges?
If so, it is not a good way because the color cartridges are more expensive
than the black one...)

PS:
I'm still searching for an help on how to manage the .icc printer profile
files....

"keeps on printing, with good result" sounded like the problem was solved.


yes this is true, but...
i don't want to use color cartridge
because they are more expensive than black cartridege

(as i told you 26 monday... :
"it will not be the solution I like,
because black cartridge is less expensive
than color cartridge.")

Just a thought but does HP provide a 'draft' mode printing option?

In HP printers I've used that offer this ("printing mode"?) option, I
think it lowers the printing resolution. (And my favourite was "draft
grayscale": black cartridge only, less ink and faster printing.)

As a consequence of the lower resolution, black may look gray-ish.

yes;
there are three modes: draft, normal and high;
and I use 'draft' mode very often,
but this 'draft' mode is very similar to 'normal'
and you don't save so much ink with it
