What could be the chemical composition of the colouring ink used in Colour Ink Cartridges?

Are all the colours mixed to form a colouring ink ?

Is it a mixture of only primary colour inks?

There is a separate Black Ink cartridge for printing Black & White and if not required colour printing.

Will it be difficult to create a single colour Inkjet cartridge which can print Black as well as different colours with modification in Inkjet printer circuitry?

Thanks & Regards,

Black Ink

Black ink is created through a combination of carbon black and a heavy petroleum distillate as the solvent (called varnish).

Color Printing Ink

The same varnish used as the solvent in black ink is mixed with coloring pigments forms colored ink. Color pigments are composed of salts and multi-ring nitrogen-containing compounds. Sometimes inorganic pigments are used. These include chrome green (Cr2O3), prussian blue (Fe4[Fe(CN)6]3), cadmium yellow (CdS), and molybdate orange (a mix of molybdate, sulfate, and lead chromate). White pigments, such as titanium dioxide, can be used alone or to modify the characteristics of particular colored inks.

Printers do not use the primary colors in their ink. Instead they use cyan, magenta, yellow, and black (CMYK). 

You're wondering why? The first thing to understand about colors is the difference between being additive and subtractive. This will help us understand why TV monitors use RGB (primary colors) and printers use CMYK.

To put it simply, on a monitor, light is being emitted (or added), which is important because when you emit (or add) red, green, and blue they create white.

When we look at ink or paint however, light is being absorbed (or subtracted) and when you absorb red, green, and blue you get black.

Hope this answers your question! Any follow up ideas, please reply back

Thanks.

If Inkjet Printers change the original colour ink to Red,Yellow,Blue,Cyan,Magenta then the Black Cartridge ink can be eliminated with modification of Inkjet printer circuit ?

Theoretically, yes, but that'd be a waste given colored ink is harder to engineer. It also wouldn't be profitable for companies that specialize in making printers and ink

Thank you.

There could be technical challenges in creating this coloured ink as you mentioned.

Red, Yellow, Blue, Cyan & Magenta.

Yeah with today’s advanced technology. it’s possible to invent one single colour Inkjet cartridge which can print Black as well as other colours but the problem is that efficiency and cost. One of the main reasons that printers doesn’t combine all inks is that it will lower the chances of the cartridges drying out from a lack of use. By moving the coloured cartridges now and again you manage to ensure your coloured ink cartridges do not dry out and fail on you. This actually makes a printer less costly to run in most cases and also saves on resources as you are not throwing out half full cartridges when they have dried up on you.

Make all colour in one cartridges together could be costly.
