For inkjet printers, this is a very important factor in the overall quality of photo printouts. Firstly, inkjet printers paint images onto paper, which is why ink plays a vital role in producing very accurate and detailed photos.
The more inks a printer has, the more color-rich, vibrant, and precise the photos that it prints will be. If you compare the digital image on the screen of the computer and the printout of the printer, you will see very little difference, and sometimes you won’t even see any, if the number of inks is high.
Some inkjet printers have as many as 12 ink colors, each with a specific use or purpose.
