1 Scope

This document describes a method for storing data in a PDF file that correspond to the processing steps of printed products. This method has three parts:

1. metadata identifying processing steps;

2. limitations on the interaction between PDF graphics objects that are part of a processing step and other PDF graphics objects;

3. limitations on PDF graphics objects in processing steps.

This method is intended to be generic, i.e. not specific to packaging and labels.

In addition, this document defines the following packaging- and label-specific groups of processing steps data:

• data corresponding to finishing steps, such as cutting, folding or glueing;

• braille;

• information panels;

• indications of physical dimensions;

• indications of intended positions of graphical elements;

• printed white, for example on transparent or metallic surfaces;

• printed varnish;

• primer;

• printing plate making.
