Macrap is poorly designed artwork that often includes, but is not limited too:
* wordart. (example: rainbow effect type on a beveled curve)
* stretched typefaces
* pixelated imagery...72 dpi is good for web, not for print.
* stretched imagery...hit the shift key, it's not hard!
Macrap is something everyone has been subjected to seeing. It can be seen everywhere from fliers on bulletin boards, posters for concerts, emailed brochures, to tv commercials...now, you know what to call it.
Basic rule of thumb...just because you can, doesn't mean you should.
That poster with really pixelated imagery and rainbow colored font on a bevel curve is macrap.
