A commonly used printing technique in which the inked image is transferred from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a water-based film (called "fountain solution"), keeping the non-printing areas ink-free.

The spine of the book block is cut and roughened, adhesive is applied to the rough edge, before a paper cover is wrapped around and glued in place.

CMYK printing uses the four process color inks—cyan, magenta, yellow and black—to reproduce a broad spectrum of colors and tones and is made possible by repeating the halftone process for each color.
