Drop a dieline PDF with artwork
One PDF, laid out flat: the artwork, the cut and crease lines, and any spot UV, foil or white plates — as spot inks or on their own layers. Package Studio finds the panels between the lines, folds them into the finished box, and lights the varnish, foil and metallic board the way they will look in the customer's hand.

A second page can be the inside print, or a separate spot UV / foil plate.
