Heidelberg Bump

Just curious if anyone else has had a printer explain a strange distortion on the press sheet as a “Heidelberg Bump” — is it a reality or an excuse?

sounds like they’re pulling your leg eh. never heard of it. but now I’m gonna ask tomorrow. shouldn’t any distortion be a matter of paperstock…not the press? i.e. cotton papers will stretch of course. vs mylar which well, can’t at all.

asked the reps on this weeks press checks.

According to all the pressmen here it sounds like a an excuse, they explain that a bump on the press is usually a bad screen from the designer files causing distortion and clogging on the screen.

Thanks for asking around, the problem that happend came from a solid pms colour with no screen. The colour was flooded through the job, however there’s a slight difference in ink consistency . I know it sounds like a big execuse on their side, but the printer is fairly reputable and I just wanted to hear if anyone else has had a smiliar situation — guess not
