If you wondered what happened to Quark in the seemingly ages between XPress 4.0 and the forthcoming-at-some-point XPress 5.0, the answer is Quark Wrapture. The application is a 3D tool for designing packaging.
Included in Wrapture, apart from a bad pun in the title, is the ability to create 3-D renderings of packaging designed in two dimensions and to export electronic mockups in JPEG or QuickTime VR format.
Quark Wrapture will be released later this year. Pricing has yet to be confirmed.
