How to take a proper screen shot

Hi, please note that I HAVE read this page before I asked the question. I have Windows 8 so I used the method listed in that link. However, when I took a screenshot of a chat violater, I had this message:

Sorry, your image resolution is too small, and quality of the screenshot too bad, so we cannot ban.

How did that come? Are there any other methods I can use?
