Zero copy (photography)
In analog photography, zero copy is the production of a paper image from an original ( negative , slide or digital data) without optimization . The optimization intervenes through special corrections (density, color) in the technical process of the output and is an everyday component of (almost) all manufacturing processes for paper images. If several images (for example a series of exposures) are produced as a zero copy, the images can be compared with one another. A sample strip (zero copy) is exposed to determine the exposure time and color cast for paper prints.
In print shops, a similar process is known as transferring the data and outputting it ready to print . However, some printing presses can also take profiles of the respective transferred color space of the data into account. A ready-to-print data transfer is usually billed more cheaply by the printer than an order that requires separate intervention by the operator.
