This method of digital printing gives by far the highest quality, achieving near photographic quality. However, it also has the most limitations in terms of speed of the print and the print size. The printing method uses a number of very small heating elements to transfer color in the form of dot patterns. The inks used are UV and moisture resistant, making them ideal for outdoor use, but the many tiled images that would be necessary for most applications also so make the cost prohibitive. Resolution suffers when viewing closer than 10 ft.
Some systems require premixing of colors and then proceed to lay the ink down one pixel at a time.
