Imposition

Skilled workers would spend many hours stripping pieces of film together in the correct sequence and orientation.

The term stripping was also used for other changes to a prepared page, such as a spelling correction, or a stop press story in a newspaper.

Digital techniques rendered stripping less necessary, but what has forced increasing numbers to abandon it completely is the introduction of "platesetters", which put pages directly onto printing plates; these plates cannot be adjusted with a sharp knife.

[2] The advent of digital imposition has not only helped a lot in making sure layout and sheet arrangement are correct with higher register precision, but it significantly reduces the usual imposition errors (e.g., slight movements of register due to parallax).

Binding options may be changed on the fly and impositions produced to multiple output devices at once, often with no user intervention.

In turn, digital techniques help to reduce material costs, time and resolves production bottlenecks.

It cannot be used as a check proof for images or colors or layout because it is printed on a large, low-resolution inkjet printer.
