How to print a pure CMYK colors in a regular printer? Let's say I would like to print a pure cyan or a pure magenta in a regular printer. first I work in a CMYK document .. but when sending the file to the printer it mix the colors and I didn't get any pure cyan or magenta. That's because of the printer driver which uses an RGB profile -most probably.

What I need is to print from my CMYK document a pure cyan or a pure magenta only.

How to do that in Photoshop or Illustrator? and what color profile is suitable for that?

in another word... "is it possible to print from only one color cartridge whatever it is?

  • Inkjets just aren't designed to print CMYK color plates. Why would you need this? I don't think this is really possible since there's no direct correlation between RGB and CMYK. – Scott Feb 21 '15 at 16:40

    let's formulate my question in another simple one. "is it possible to print from only one color cartridge whatever it is?" – hsawires Feb 21 '15 at 16:54
  • Hack and fill all cartridges with magenta ink... cannot guarantee the hardware will survive :-) – curious Sep 18 '17 at 22:46

Your Inkjet printer has to support CYMK. Thus double check before you proceed. Otherwise colours are always converted to RGB. Also make sure that the latest printer drivers are installed.

You can export your Illustrator/photoshop file to a PDF file. This way you can open your document in Acrobat which offers advanced print settings like preview color separations. The Colour profile depends on the final medium e.g. coated, uncoated, newspaper... When you export your PDF make sure that you are using the same color profile e.g. sRGB or Adobe 1998.

Only works if you've a way to map a given single color from one profile to another

I faced the same issue and I wanted to print from one cartridge to just unclog a few nozzles without wasting ink from the other cartridges.

My printer ICC profile was Epson sRBG. I believe any print work would be first mapped on to this RBG profile first and then the printer would convert that to it's own CMYK internally to fire from respective cartridges.

First Trial: I tried printing a patch of color with RGB(255,0,255), thinking this should print perfect Magenta, but that was not the case.
Second Trial: Map CMYK(0,255,0,0) to Epson sRGB and print that patch of color. Almost there but not perfect yet. As obviously the CMYK profile I used was not the same as the printers and also I was using some cheap ink ;-)
Final Trial and Error: So I tried to get the perfect RBG combination so that it prints from Magenta cartridge only, with target around CMYK(0,255,0,0).

I tried this exercise using all the below CMYK profiles for my test print...
WebCoatedFOGRA28
CoatedFOGRA27
Generic CMYK

What worked for me was Generic CMYK with a bit of trial and error. I printed multiple patches. I created a simple spreadsheet that would create my patches around the colors I required. Printed all patches on same sheet to finally choose the one I needed by the eye. Here is the spreadsheet I used. Each color is fills 10 rows with details of the color mentioned. So I have like nine patches that gets to 90 rows to fill up a whole Letter/A4.

Also the way I went from one color profile to the other was by using the Color Sync Utility app on Mac. I'm sure there is a similar utility on windows for the same.enter image description here

Let me know if you've a similar convertor utility for Windows, I will added it to the answer.

Cheers and happy printing!

I also tackled a very similar problem. I was not getting pure Cyan output from my Epson WF-7520, even though it has CMYK cartridges because the printer was converting the CMYK source document to RGB before printout.

I was able to obtain a reasonably clean Cyan after converting the source document to RGB and setting the color to 'pure cyan' in RGB values, which apparently is R=0, G=255, B=255.

  • I find this confusing. The link I posted is another question/answer thread on Stackexchange. The posted link above to the 'thorough answer' thread seems to fulfill the same function. My intention was to avoid reposting the answer content from the linked question in this one as it seemed a redundant duplication of content. However, as I'm still learning the ropes here, I am rewriting the post to describe the solution I found. – Geoff Dec 22 '16 at 20:49
  • no the link you provided is to the Adobe forums and we have no relation with them. Regardless if the Q&A originated from here the answer should be able to exist without relying on an external source to prevent link rot. – DᴀʀᴛʜVᴀᴅᴇʀ Dec 22 '16 at 20:52
  • Sorry. I realize I posted the wrong link. Corrected. – Geoff Dec 22 '16 at 20:55
