Due to recent advances in technology, duotones, tritones, and quadtones can be easily created using image manipulation programs. Duotone color mode in Adobe Photoshop computes the highlights and middle tones of a monochrome (grayscale or black-and-white) image in one color, and allows the user to choose any color as the second color.

Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch ...
