ZINK Imaging, Inc. is a technology company specializing in the development and licensing of its proprietary printing technology, ZINK (Zero Ink). While their website focuses primarily on the technology itself and its applications, rather than acting as a direct-to-consumer photography service, their core function is fundamentally intertwined with digital photography.

ZINK's core offering is the ZINK printing technology, a method of printing images without the use of ink cartridges. The process involves embedded crystals within a special paper that change color when heated, creating a full-color image. This technology enables the creation of small, portable, and instant photo printers. ZINK doesn't produce consumer cameras; instead, they license their technology to manufacturers of various consumer electronics, including smartphones and other devices. Their role is thus indirect within the digital photography landscape, enabling the seamless printing of digital photos captured via many different devices.
