Generate bleed from page content (8.3)

In pdfToolbox 8.3 you are able to create bleed in CMYK + spot color (If the input file has spot colors) or Grayscale. With the previous version 8.2 you could only create bleed with sRGB, CMYK or when the PDF has an OutputIntent.

This tutorial shows how to generate bleed from the spot color "HKS 10 N".
