Summa OPOS cutting alignment promblems

[Warren Beard]

what size are your registration squares (5mm?) Make sure you have calculated the gap between the left and right correctly as you need to take the full width and not the repeated step width.

ie: if you have a 5mm square and you move it 505mm across the size to enter in to the cutter is 510mm and not 505mm, it’s the width from furthest left to furthest right (ie: select both registration squares and that width it gives you is what you need.

If that’s not the problem then I’m not sure sorry.

Hi Warren i think i know what you mean but they are out on both the x & y axis. I have tried running shorter print & cut runs from 4.5mtr x 1370mm to 2mtr runs with success but would have thought that 4.5mtr x 1370mm 27up 500 x 400mm not over complicated contour cut. (should add they have been gloss laminated) "but even that" I would 4.5mtr was to much to expect from a brand new machine running oynx print & cut Mutho edition.

"Perhaps I am"

Late had enough going to bed and hopefully I can rescue some of the 175 already printed and laminated a but seem unable to register to cut properly.

Fresh eyes in the morning might help!

X/Y values are from the lower right of first mark to lower right of second mark. So if you have 2mm squares (what I normally use) and move the OPOS mark 500 mm you need to input 500 mm. Also having more OPOS marks tends to make it more precise. I usually try to have around 400 – 600 mm in between Y marks.

I thought the new version on winplot which installs into draw had an automatic mark generation button and that sorted how many marks to put on depending on objects being cut, and then just click the cut icon, move the head over the first mark when prompted and then off it goes.

You may find the laminate the cause as it struggles to read the crop marks through the laminate. Try wiping a cloth over the crop marks to make sure it is clean also press on quite hard over the area as the laminate can cause a bit of silvering making it hard to read, rubbing the laminate can reduce the silvering and hopefully the eye should pick it up now. Next time you laminate and need to contour cut after, put a little piece of application tape over the marks and laminate then simply cut around app tape and remove leaving you with clean easy to read crop marks.

Alan I heared that today as well but havnt had a chance to investigate the winplot plug-in feature.

Steve I think the laminating is not helping but I found out today that there is a know glitch with the onyx software I have that puts the dots in the wrong place or something but at the moment I just need to get the job doing and out the door as soon as possible so have decide to run 2mtrs at a time really slowly as this seems to give good results and I will sort out why & who’s picking up the tab.
