[texhax] colortbl pdf problem

[Philip G. Ratcliffe]

Sorry, if this is a repeat but something funny happened to my computer
earlier just as I was posting.

Anyway, my question is if this isn't just a problem of screen resolution.
That is, does the problem persist in the printed versions?

Cheers,  Phil

P.S.  I get LaTeX errors with the "minimal example" provided - it doesn't
klike the \arrayrulecolor[cmyk]{1 0 0 0} command.
