About this envelope

The envelope page for a size no preset covers: C6 to begin with, and the sliders run from 110 to 240 mm wide and 90 to 170 mm tall, never taller than wide. The flap depth and the seams follow.

Pick the flap, paper and liner, add artwork, turn it over and open it with the slider, and export a transparent PNG.

Questions

How is the back printed across the flaps?

As one image on the flat blank; after folding, only the visible outsides of the flaps show it, which is what you see here.
