I wish that Sweet would explain his workflow so we could tell him what he's doing wrong. The online -- and doubtless the printed -- versions of his comics are almost certainly more awful than they should be.
For example, the finished product displays noticeable jaggies on every element that is not a horizontal or vertical line. This is almost certainly a result of his inability to set his scanner's parameters correctly. Using a low resolution for faster scans and smaller file sizes is undoubtedly part of the problem. And it's dollars to doughnuts that he doesn't understand that line art should -- somewhat counterintuitively -- be scanned as gray scale to improve the quality of the final image.
Another major problem is his utter lack of attention to detail when lettering. Take the following example:
In the main dialog balloon,
great looks like
gre6t, one looks like
ome, hack looks like
haol, and
doesn't looks like
do6smt. Random words and random letters within words appear to be in bold face. The idea that text should have a baseline is alien to Sweet, which makes his walls of type even more difficult to follow. And this example is fairly clean by his standards.
He must ink the lettering before he scans the line drawings. Doing this in MS Paint would take forever. It's a pity he can't be bothered to do the job properly.
As a famous cartoonist, Sweet owes it to his adoring fans to explain his workflow in exacting detail. Types of paper, pencils, pens and inks used. What elements are inked before scanning. Make and model of scanner and a complete list of settings. Procedures followed in MS Paint. Once we have this information, we can begin our own humble and unworthy attempts to imitate the master.
