[tlhIngan Hol] Are there two KGT versions?

Hi, I have noticed that there are two different prints of KGT, and I wonder if one of them is an illegal copy or not. The difference is easy to see: One version has very white paper with a clear printed black ink. The other has yellowish paper (like TKD) but the print is not very clear. Even those areas that are white (i.e. empty) still show tiny dots produced by the printer. It looks like someone made a scan of KGT and then printed it. Even the cover looks like has been copied. Has anyone ever noticed that? Or is it maybe even known that this exists? Fake or intended? -- Lieven L.
