I can only report my experience printing with gum, which corroborates
Clay's surmise that open shade will make a softer print. I was surprised
how fast gum printed in shade, but compared to a print made with the
same printing frame in direct sun or indoors, the print made in shade
was unacceptably diffuse. Small objects or details that in the other two
conditions printed as recognizable shapes, in the shade condition
printed as round blobs, for example.
