How sensitive is the reader to ambient light falling on the target?
The instructions say nothing, one way or the other.
Easy enough to test for yourself, with the spot reading mode. I find I can shine a whole lot of light on the target without having the density or L* value change (take a few readings to warm up, then read every couple of seconds, as you add or remove light). A thick translucent media, like drafting mylar, might "fiber-optic" a bit of light in, but other than that, even heavily textured papers or canvasses don't read very differently with or without ambient light.
