These rolls contain solid dyes with either three or four colors. This technology is typically used to create proofs or graphic designs. Dpi stands for dots per inch, with the highest resolution having the most dots. With color printers, dpi is not always a good measuring tool. The process by which the colors are created can affect the quality of output.
Color printers create color by mixing black, cyan, magenta and yellow.
The colored dots are placed closely together to produce the desired color. Continuous tone printing combines the colors in varying amounts on top of each other to produce a visual impression of a single color. Dithered images need more dots or a greater resolution to create the same quality of image. Dithering printers typically offer resolutions of 600 to 1200 dpi. Resolution is also affected by the technology.
