Black ink is a generic term used for many products from simple newspaper ink to highly sophisticated ink jet printer inks. Black ink is formulated primarily with carbon black pigment and a carrier vehicle in which it is finely dispersed. The vehicle can contain various oils and/or resins and additives, with or without solvents depending on application method, the substrate, and the drying conditions.
Only a substance can be categorized as an element, a compound, or a mixture. An ink pen is not a substance, it is an implement.Added:The 'ink' (IN a pen) is definitely a mixture,not an element or pure compound.
Black biro ink typically consists of a mixture of black, blue, and purple color pigments. These colors combine to create the dark and rich black color commonly seen in biro pens.
it is a mixture..homogenous and a colloid one....
The color of ink is usually produced by a mixture of two or more dyes. The specific combination of dyes determines the final color of the ink. Different dyes absorb and reflect different wavelengths of light, creating the perception of color to the human eye.
The ink may be a homogeneous mixture.
compound
The evidence that exists that marker ink is a mixture is that the ink can be separated into black and other color pigments. This can be done on filter paper by dotting the marker just above the edge and adding ethyl alcohol, which drags the pigments separately across the paper.
The black ink is supposed to be darker than the colored ink. However, black ink is composed of all the colored inks combined. Thus, it is merely a mixture of all the other cartridges. This is why is should be bolder and darker.

ink is a mixture of a carrier and a pigment.
Dye and black ink can be separated by chromatography, where the mixture is dissolved in a solvent and allowed to move up a filter paper. The different components in the mixture will move at different rates based on their solubility in the solvent, allowing them to be separated visually.
its a substace because it not pure... how do i know.. well i just do Some are pure substances : chalk, charcoal, graphite and pure lead are examples. Some are solutions, some are suspensions, many are a mixture.
