I believe it's because they have a gravitational pull so strong, that not even light can escape it; hence, utter blackness.
A black hole is considered "blacker" than black ink or black paper because it absorbs all electromagnetic radiation, including visible light, and reflects none. This means that no light escapes from it, making it appear completely dark against the backdrop of space. In contrast, black ink and paper can still reflect some light, albeit very little, which is why they are not truly devoid of reflectivity like a black hole. Thus, a black hole represents a region of spacetime where gravity is so strong that nothing can escape, rendering it the ultimate "black" object.
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.
Yes, Egyptians are credited with developing a form of black ink made from carbon black, gum, and water. This black ink was commonly used in ancient Egyptian writing on papyrus scrolls and other surfaces.
You can use the filter paper or chromatography paper to separate the different components in black ink.
Iron gall ink is a black ink made from iron salts and tannic acids, typically from oak tree galls. But I do not believe tannin was ever used. However one could make an ink like material based on iron salts and tannin. However such inks are very bad, being acidic they attack the paper and can eventually "burn" holes in the paper whenever the ink was applied. There are much better inks and inks of a wide range of colors now.

Yes, black printer ink is cheaper than colored ink in general. It's also easier to refill black ink yourself.
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.
Yes, black ink is generally cheaper than color ink because it is used more frequently in printing. Color ink can be more expensive due to the additional cartridges needed to produce different colors.
To make black tattoo ink appear darker, artists often mix in a small amount of carbon black pigment, which enhances its depth and richness. Additionally, using a higher concentration of ink during application can create a bolder appearance. Some tattoo artists may also use a technique called "packing" to ensure the ink is thoroughly deposited into the skin for a darker effect. Always prioritize safety and quality by using approved inks and techniques.

Having more money than you owe. If you have less than you owe then you're in the red. Banks used black ink for positive entries and red ink for negative entries in the ledger
Yes, there is i experimented, and there is brown, black and yellow!
photo black ink is more expensive
is black magic ink the same as India ink
Yes black ink radiates more heat than white paper. This is because more heat is absorbed by black ink more than white paper and it is required to radiates more heat due to its heat capacity
"No, actually blue ink tends to be easier to read then black. If you are writing on a sheet of paper with a letter face or an application chances are that the print is in black, blue ink, therefore, being easier to read. On a plain sheet of paper this is also true for blue ink because it is a color, and the human brain is stimulated by color. This causes your eyes to see blue ink easier then black."
