Nested Step and Repeat is an option in PACKZ to impose folding carton designs using the CF2 cutting die retrieved from the CAD system. The user browses through diecut libraries using the Quick Look Function, and sees the preview without the need to import the file. PACKZ generates full colored step and repeats or dynamic templates that can be reused at any time. A single click instantly creates the back side out of a front repetition. The Translucent Quality Assurance tool shows the register between front and back side. Different single designs may be combined in a repetition, in which each station can define its own station number, positioning and bleed handling. The Common Knife tool detects, highlights and allows users to set the bleed priority in the stepped result. Defining and storing these priorities in the 1-up station can automate the process.
