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.
ink is a mixture of a carrier and a pigment.

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.

It is a mixture, because everything in it retains their characteristic properties.
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.

Mixture. A compound is a single substance consisting of atoms bound together (for a very simple definition): water (H2O), Ammonia, etc. A mixture is a combination of coumpounds/elements that are physically, not chemicall combined. When you dissolve sugar in water, you have a sugar-water mixture, not a compound since you do not obtain a single substance "sugar-water" with a unique chemical formula.
Ink is a mixture composed of pigments, solvents, and additives. The pigments give the ink its color, the solvents dissolve the pigments and control the ink's viscosity, and additives can provide various properties like drying time or water resistance.
