Some of my cartoons (a minority) can receive a few extra tweaks. For example, if there is a clean gap between panels at or very near the center of the comic strip, I can effectively cut my cartoon in half and stack it in two layers (up to four with some Sunday cartoons). This makes for a larger cartoon that can be completely read onscreen by simply scrolling down.
Even fewer cartoons are drawn sideways, and, with a couple clicks of a mouse, can be rotated 90 degrees for a more appealing look.
And that’s how it’s done!
