Need Help Tiling wall graphics won't line up

What kind of HP are you running?

 

what press are you using and are you using software for the tiling or manually?

 

Yes. Depends on the printer though. I'd assume HP Latex. Which means they need to run a media advance calibration and make sure to rotate panels.

 

I do this and occasionally have issues with lining up. It seems to happen most on jobs that are 4 or 5 panels, where just one out of the batch is off. And the length of the panel is different, almost like the art was stretched during printing.

 

We could get acceptable results on our 360s by turning off OMAS, printing the panels in sequence to minimise colour shift and print all panels together in one print run.
If you have to reprint a panel all bets are off.

 

Our HP 365 was causing problems with panels not lining-up when printing vinyl (Oraject 3651). Our OMAS was broken and after fixing it we never had these problems again. We also run our jobs with the special hardware on the tension bar (weights that keep the tension minimal) and Long run consistency mode in the profile.

 

are they laminated graphics? I think everyone addressed the printer issues...besides reduce heat. If laminated, make sure you have almost zero tension or brake being applied to the lamination film spindle...

 

The OP hasn’t actually replied since making the post. We’re all just guessing they have a HP. Could be a multitude of reasons I guess. Most posters have a habit of supplying information in dribs and drabs
