What is the most common type of ink used in printing?

The most common type of ink used in printing is called pigment ink. Pigment inks are typically used in inkjet printers, which are the most popular type of home and office printers. Pigment inks are made up of tiny solid particles suspended in a liquid carrier. These solid particles make pigment ink more resistant to fading than other types of ink, such as dye-based inks.

Pigment ink is also more versatile than other types of ink, as it can be used on a wide range of paper types and other printing materials. Pigment ink is commonly used for printing text and graphics, but is not well-suited for printing photographs due to its relatively low color saturation and limited color range.

Other types of ink used in printing include dye-based ink, which is commonly used in photo printers and produces high-quality, vibrant images, and solvent-based ink, which is used in large format printers for printing banners and other signage. Toner is another type of ink used in printing, which is commonly used in laser printers and photocopiers.
