die cutting pre-printed material

Postby Leadpress » Thu Apr 04, 2019 2:03 pm

Guys! Trying to maintain a die cut on pre-printed material, using auto register on Nilpeter, but the auto register can't keep up. three or four good repeats and then major shifting causing the die to cut into the artwork. Does anyone have any ideas? What's the difference between printing something and die cutting it at the same time, using the auto register, versus something pre-printed? Why does auto register move so much?

Are you printing and then diecutting all in 1 pass or are you trying to re register a previously printed roll?

Is this press fully servo or is only the plate roll controlled by servo?

Hi Leadpress,

If it's a Nilpeter FA series you will have to use the offset function. Depending on if the die register advances or not put in for example - or + 0.5mm depending on the amount of correction needed. Also make sure your repeat length is typed in correctly.

Carbon, it's an FG series. Does that have the same feature? If so, where?
