That said, i've noticed that you're using [scale=.4]. How would it look without scale=.4? The point is that DPI info should allow typesetter to guess image size correctly, and it should look OK without scaling. Or not. After all, default image resolution does not seem to have any relation to dpi=..., so high dpi means "scale down", while low dpi means "scale up", but increasing/decreasing resolution (using figsize) will throw that scaling off...Damn. OK, so the right way is to specify dpi that is high enough for "printing" (that would be 300), then increase image resolution with figsize until the image is large enough. Right?
