Gang sheets
Impose a batch of small jobs together: drop every file, pick the sheet, and they are placed and rotated to share it. The nearest thing to a hot folder that needs no software.
Select many PDFs at once; each becomes an item on the sheet.
The batch leaves as a single press-ready PDF with crop marks.
Runs in the browser on any machine in the shop.
The defaults come from your file. Change a setting and the proof updates before you let go of the mouse.
