Dear Forum,
I am trying to add a background image of a piping schematic, over which I am placing various formula-derived values for temperature values that apply to the schematic. This means that the background image and the formulae need to align with each other closely!
So far, I have:
* made my .png watermark image the exact same dimensions as the Print Area
* discovered that watermarks are scaled in Page Layout to the same value as is used by Page Setup (so I set it for 100%)
* and tinkered with everything I could think of, but still...
* in Page Layout everything displays perfectly, but when I print or use Print Preview, the background image stretches to the right 10mm / ~10%. This causes all of the alignment on the right side to become incorrect.

I suspect this is an uncommon application of a watermark background, but I am hoping someone can offer guidance regarding how to make it work. Thanks in advance!
