5m high wall wrap – advice needed.
I am quoting on a 5m high x 8m wide wall wrap. I am planning to print on Arlon DPF207 (it’s only got to last a week) on an HP latex printer. My question is, has anyone printed a wrap a this height on a latex printer. I have had problems with registration on overlaps on 1.5m jobs before now, and that was down to the OMAS being turned on. I would turn it off for a job thiis long but is the machine accurate enough for good registration over this length?
Thanks

Turn off OMAS and alternate every second tile.
You’ll be fine.

Hi Jason
There is a function in Onyx to alternate the tiles I think. What does that do exactly? Print it the other way up?
-
The reason to alternate tiles is this..
Different areas of the printer might have subtly different characteristics, say the colour laid down on the left side might be a tiny bit lighter than that laid down by the right side. The problem gets worse the older the printer gets.
This is more apparent with lighter shades. Cloudy blue skies etc.
So you try to get the adjacent parts of an overlapped print coming from the same side of the printer.Simon

Unbelievably simple advice. I cannot believe I have not already tried it. I do many large wall wraps and have never tried to alternate tiles. I will tomorrow. Apologies for being simple but Why should I turn the OMAS off.

Stephen as I understand it the OMAS causes the printer to make on-the-fly changes to the substrate advance, meaning it can vary throughout a job. This is fine when 100% accuracy is not important but for long jobs or where overlaps need to join up perfectly it causes problems. I have had 1500mm jobs be out by 15mm 😮

I would outsource the printjob, and let it be printed on airtex on a 5m wide printer…
Here in Belgium costs around 20 euros/sqm for seamless prints up till 5m wide and 50m long max. -
Hi Tim
I did think of that as we have done a couple of flex face jobs, but nothing as high as this. The problem is that I can only get the material printed in one piece on a UV printer and that causes problems as on fabric apparently the ink cracks easily and it has to be transported and fitted extremely carefully. I have offered it to the customer as an option though so we’ll see…

John, perhaps split in 2, that way only one join, and easier transportation…
