Then hold the printed piece upside down towards a mirror and then look at it. Relax your eyes, gaze at a copy block and don’t even try to read it. See if you notice any areas that seem darker or lighter within the text block.

If you do, then the spacing is either too tight or too loose in that area. If you don’t, then either your spacing/kerning is fine, or need to continue training in typography… that is, if you’re still interested.
