European Article Number

EAN has been replaced since 2009 by the name GTIN (Global Trade Identification Number) synonymous with 8- and 13-digit bar code.

The EAN or better: GTIN numbers contain the issuing country and a reference to the manufacturer as well as a serial product number and a check digit. The numbers are assigned worldwide by GS1.

The Proof GmbH is a member of GS1.

Early binding

“Early Binding” workflow means that RGB image data are converted into the planned CMYK print colour space as early as possible during separation. Usually this is done in Photoshop, and the already separated image data is then placed in InDesign.

In the best case, this results in a layout document completely built up in the CMYK output colour space, which can be exported directly into a PDF file in the output colour space without colour space conversion.

If, however, the output colour space is changed at a later point in time, for example because printing is to be done on uncoated paper instead of image printing, all images must be completely rebuilt and imported or embedded. Therefore the “Early Binding” workflow is considered inflexible and not media-neutral.

Alternative workflows are the Intermediate Binding and the Late Binding.
