It's a heterogenous mixture, even though it has different particles of color mixed into it, it still is blended evenly.
The ultra-fine particles can be separeted by ultra-fine filtration, but do not get sedimented by their own 'brownian' movement. They are above molecular scale, though not vivible by naked eye, they can be detected onder light microscope.
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.
Green ink is homogeneous because it is a single phase solution where the ink molecules are evenly distributed throughout the solution.
Newspaper ink was traditionally made out of a mixture of carbon black or lampblack, oils, resins, and solvents. Carbon black was a key component as it provided the black color in the ink. Today, soy-based and vegetable-based inks are more commonly used as they are more environmentally friendly.
No, a marker is not considered a homogeneous mixture. It is a heterogeneous mixture because it is composed of different components that are visibly distinguishable, such as the ink, plastic casing, and tip.
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.

it is a mixture..homogenous and a colloid one....
compound
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.
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.

ink is a mixture of a carrier and a pigment.

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.
