On the technical  side, the billboards are 680 by 244 inches and 426
by 244 inches. I was asked to prepare files at 1:10 scale, with raster
images at 720 dpi.

I created a two-page project in Scribus, 68.0 x 24.4 inches and 42.6 x
24.4 inches. I layered forms, images, and text, until the design
emerged.

The difficulty would be to get the photograph at its required size. I
used CaptureOne to treat tif files as raw files, and to gradually
scale the image files to the desired specs--20 x40 inches at 700dpi. I
hope to be able to do this with Darktable, but I have not tried.

I did not know the specifics of the printer, but I suspected it would
be something like a Roland LEJ-640.  So, I output a pdf 1.3 with cmyk
colors, crop marks, and 3-inch bleeds; it was a 2GB file.

Scribus performed beautifully.
