yep we punch to komori punches - register was almost exact from the off (screen 8000 II)
although we've only had ctp a couple of months now - i think i'd recommend punching in the ctp, going on the results we have had here. pressminders like it
We punch 3 Heidelbergs in our CTP device. Register is bang on. Its another area where you take out the possibility of errors caused by different people punching the plates.
We have had to manually punch our plates all along, however that will be changing with the new platesetter that is being installed as I type this. We hope that the online punch in the CTP will eliminate the occasional plate remake because of bad punching by an operator.
We retro-fitted our Agfa Ascento S with an internal punch about 6 months after install. We have a Komori Lithrone 20 x 28 and the internal punch saved an average of 4-5 minutes of registration time per from, and about 30-50 sheets of paper per form. ROI was about a month.
We punch plates in our AccentoS. We have two presses with different punch…no problem. Had a period with missregistration and it had to do with gradations building up in punch OR loading roller not gripping if build up of aluminium.
New cleaning routine cleaning roller and punch when cleaning plate cleaner (not linked but just to get a good service routine) seems to have solved it.
We used to punch offline (2 Trendsetters) and also had a Lotem (online punching), but ended with 2 Heidelberg Suprasetters (online). The Suprasetter was the best with the ability to run plates from either unit with the same registration. Press setup was most reliable and registering speed with the Suprasetters. The value of online punching was a huge labor saving in prepress considering we ran 10,000 to 20,000 plates per month.
