ZINK, which stands for "Zero Ink", is a unique type of picture paper that is colored without using ink, ribbons, or toner by employing crystals and heat. Polaroid invented zinc paper, which became a separate company, ZINK Holdings LLC, in 2005. Zink is the sole company that manufactures the paper; however, it licenses its technology to other businesses, such as Polaroid, Canon, and Lifeprint, so that others may use it to make instant cameras and small printers that use Zink paper. These companies also offer branded Zink paper for their goods.

ZINK paper is mostly utilized for portable printing and instant photography. Users may print pictures while they're on the go thanks to its compatibility with a variety of instant print camera and mobile printer brands. This cutting-edge technology is popular for scrapbooking, sharing physical photos, and other uses since it provides an easy, ink-free way to print pictures instantaneously.

ZINK paper has heat-activated dye crystals embedded in it, giving it a glossy photo-paper appearance. These crystals change color when heated by a ZINK-compatible printer, producing a full-color print.

ZINK paper offers the advantages of being waterproof, long-lasting, eco-friendly, and having an adhesive backing. ZINK film is also vegan, in contrast to Instax Mini or Polaroid i-Type film. This indicates that there are no animal products used in its production. Ordinary instant film is made of gelatin. The marginally lower image quality brought on by the considerably weaker color reproduction is a commonly stated drawback.

ZINK paper is composed of seven layers per piece. When combined, the layers are so thin that they are roughly the same thickness as a single hair strand. Every sheet of paper contains 100 billion dye crystals that are just waiting to release an image.

The ZINK paper takes around thirty seconds to print. 200 million heat pulses occur within this period. For a low-temperature long-duration pulse, only the yellow crystals will melt while the cyan and magenta crystals remain solid. This means that each pulse only melts the targeted color crystal as long as it aligns with the color collected. It creates pictures by reacting to heat through the use of colorless dye crystals implanted in the paper. 

A frequently asked question: What makes ZINK different from Instax? Classic instant film, or Instax, uses chemicals in the image to react and reveal colors. Zink images are completed the moment they are released, while photos taken with a camera still require some time to develop. Instax photos also have that classic “Polaroid'' look, while ZINK has a more paper-like look. The latter is more durable though, waterproof, and has a sticky back. 

ZINK paper is an innovative inkless technology that provides both environmental friendliness and ease. Even though its color reproduction can be a little bit worse, its affordability and practicality make it a good option for portable printers and instant cameras.
