Denis knows PostScript better than (or was it then?) English. Rather than re-rip a file, he's been known to tweak the PostScript directly. All in the interest of saving time (and to prove he is every bit the print-guru we think he is.) While most of us Webbies no longer care about fractions of a point, Denis adheres to his self-imposed zero-tolerance policy.
When he isn't prepping a job for the presses, he spends his time learning to program the Web, scuba diving, teaching the Marines a thing or two or karate.
