Different kinds of ink are made for different purposes and they require a variety of properties; how easily they flow, how rapidly or slowly they dry, what kinds of materials they will adhere to, how permanent they will be, how expensive they will be, and so forth. Sometimes the most efficient way to make a black color that has the other characteristics that you are looking for is to mix other colors that together will look black. You can also use a pure black such as carbon powder or cuttlefish ink, but that may not have other properties that you want in that particular ink.
