Sorry for the off-topic post. I think the term has something to do with typography, but I can't be sure as I don't understand it :)
It appears in this sentence about bad dictionary layout:
Vores egen erfaring er, at der findes ordbøger af høj kvalitet, som har et så uroligt læsebillede og en så lille skrift, at brugen er vanskeliggjort.
which comes from this paper: http://netordbogen.asb.dk/Lit/Hermes/H04_02.pdf
I can see that it comes from "read" and "picture" but beyond that I can't make heads or tails of it. If anyone could explain what it means, I'd be much obliged.
