Not only are there hundreds of shades of black, but industrial inkjet ink manufacturers can control other properties of the black ink down to a molecular level. Adhesion, longevity, and decap time play a role in formulating a black ink specific for the intended application.
Pigmented black ink starts with a dry, powdered compound created from carbon particles. These pigments are mixed with a liquid like water or oil to create the ink. The pigment remains suspended in the liquid. The ink formulation cure or evaporates after being applied to the substrate, leaving the pigment bound to the surface. Dye-based black inks use colorants that are fully dissolved into a liquid like water or oil.
Most black dye-based inks include a combination of black dye and additional cyan, magenta, and yellow CMYK dyes to create a rich black. When dye-based ink is applied to a surface, the fully dissolved liquid soaks or etches into the surface. Dryers then evaporate the ink to prevent it from smearing.
Black ink formulations are almost infinite. For a specific application, inkjet chemists may choose to create a fully pigment-based ink or a fully dye-based ink, or they may combine pigments and dyes. One common scenario involves chemists taking a pigment-based ink designed for durability and maximum adhesion and adding black dye to improve the brilliance of the color.
Additionally, ink chemists can choose from multiple black inks and dyes, each having slightly different hues. Many standard dye-based inks often look blue once printed, and many pigment-based inks can appear somewhat brown. By carefully choosing to use specific dyes or pigments, ink manufacturers can meet precise color specifications. Learn More. You are using an out of date browser.

Thread starter ghwellsjr Start date Aug 9, There have been many statements in this and other printer forums about when a Canon printer uses the black pigment ink and when it uses the black dye ink.
Most of these statements are half-truths and some are absolutely false. I'm not going to bother reiterating the false or half true statements, just the truth. The truth is that the black pigment ink is [almost] always used on plain paper--never on photo paper and the dye black ink is always used on photo paper--[almost] never on plain paper. When doing duplex printing, the black pigment ink is cut to about one half of the intensity that it would normally print.
Then, to make up for this decrease, the magenta and cyan inks are printed in the same area as the pigment black. The yellow and dye black are never added to the pigment black to make up the difference.
In fact, yellow, along with magenta and cyan, is blended for some shades of grey. Also, it doesn't matter whether the duplex printing is done automatically or manually, or whether you are doing booklet printing. And, in all cases, we are talking about duplex printing on plain paper. Now for some background. On this forum, the main discussion can be seen by searching for "duplex pigment". One of these threads contains a reference to some very lengthy discussions on comp.
Reading these will make you appreciate this forum--what a nightmare! The printers I tested were the Canon MP and the iP, both of which use the same print head with five cartridges: the larger BCI-3e pigment black, and the smaller BCI-6 dye inks including black, yellow, cyan and magenta. I presume the same results would apply to many other Canon printers that include both types of black ink.
In order to perform the tests, I cleaned five Canon cartridges and filled them with cleaning solvent from inkjetsaver. After a sufficient purge, these cartridges print nothing visible on the paper which is necessary to draw correct conclusions. I then replaced one of the cartridges with a regular ink cartridge and, after a sufficient purge, printed in various modes to see if that particular ink was involved in that mode and repeated for each cartridge.
A "few". Now that is useful information and helps settle a very old debate Just a small note for clarity, you might want to edit your post in this bit to avoid any confusion.. The yellow and black are never added to the pigment black. Click to expand The yellow and dye black are never added to the pigment black.
For example, if you remove a depleted black printer cartridge and try to print with the just color cartridges installed, your printer will not function. Yes, you can print black by combining percentages of cyan, magenta and yellow. However, The printer this tri-colored cartridge is for and every inkjet printer also requires a black ink cartridge. If the black cartridge is empty or missing, the printer will not work until the black cartridge is replaced.
The printer is designed to print when the ink is low, but once the ink is completely depleted, the printer will also stop printing. The reason behind this is because the depleted cartridge will damage the printhead of the printer if tried to print.
