Having problems with even inking?

I myself have problems sometimes, especially with "bold" images, where the ink doesn't evenly cover the image I want to stamp. Well, I've heard lots of different ideas on how to fix this and came across the following information from a blog I came across:

Do your prints have blotchy spots? Fix it!!
A lot of people have problems when trying to stamp larger images, they end up with blotchy spots where the ink didn’t fully transfer. This can be VERY annoying, especially when you don’t know how to fix it.
Well, you’ll be very happy to hear that there is an easy fix for your problem. All you have to do is gently rub the rubber stamping surface with an ordinary eraser! Yes that’s it.
An ordinary pink eraser (or any type really) is all you need to soften and clean the stamping surface. This will allow the stamp to fully disperse the ink and eliminate those annoying blotchy spots.
You might find that your stamps are particularly old and the rubber has hardened considerably. In this case an eraser might not be enough to soften the rubber. When this happens you might want to try some fine grit sand paper, I suggest 120 grit or finer… a gentle rub is all you need to get those stamps like new again.
