Print quality issue using a high resolution image.. help please?
Hi all, could do with some advice please!
The first photo (hopefully in order) shows vertical banding as the print is coming out of the printer.. I aborted this print and put it down to poss too much heat but mainly too much vacuum on the platen, causing high and low spots, this was on a std 10pass print quality using a very high quality composite image.
I decided that as this print is going above my printer on the wall I’ll up the quality so, increased to a 16pass print and lowered the vacuum which cured the vertical banding, however, as you can see on the left half of the print is some fine banding, does anyone know what’s causing this?
It printed fine to begin with only banding 2/3rd in, there’s a lot of effects going on in the composite photo so I don’t know if it’s struggling with the lighting? Higher ink load perhaps?
I have 12mtrs to print for the same , very good customer who built this bike so want to get it bang on! The other print is much lighter in colours but still…
L26500 onto Metamark artisan s/a wallpaper!!
any advice welcomed!

Have you tried printing same image onto a S/A vinyl ?

As Ian has said, you need to try printing this onto a vinyl you already use and know it prints 100%
if the prints on the vinyl are perfect, you know its not the machine and is down to the media used.if it is the media being used… you may have the wrong profile!
I would imagine metamark will have the profile required for your machine combined with their media, to download on their website. -
Thanks Rob, will try that tomorrow 😉

Also run a print quality check plot, make sure everything is firing correctly.

I’ve now printed the exact same file – both on same standard glossy HP profile, the banding only occurs on the vinyl print in the last 10%..
Both KY heads are way way over their warranty / usage and ordinarily print fine, do you think changing them will make the difference?

Run head plot test print, and see how that looks before swapping them out

Will run it shortly and post here. Thanks

Hi
We had exactly the same thing with a job we printed a couple of years ago. Same printer, same material. We needed two rolls for the job and one was much better than the other. In the end we got it printed on a 360. Still wasn’t perfect but good enough.
Hope this helps

Ok, so I think it’s time the black head were swapped out, I’ll do a couple of cleans first check..
-
Yup, will swap out No.3, head 4 seems good bar two tiny specs missing ..
Head 6 magenta looks iffy on the solid colour but perfect on the grids, it’s OOW so I’ll prob change that too, would you agree?
-
Yup, you got an issue there with the black head Those lines in the magenta will not help either 🙁
Metamark artisan wallart media is good – should have no issues with print quality, this was printed a year or so ago and hangs on our workshop wall – solid..solids 😆
