Arlon DPF6000 XRP Printer Settings

[toodark]

We are printing on an HP Design Jet 26500 and printing a wrap on this material. The first 5-6 inches look great, after that the ink seems to not be laying right on to the material and resulting in white spots through out. I'm new to the 26500 and we have been printing on oracle with no problems. First time we have tried the Arlon. Any tips/thoughts?

The settings we found on HPs site were and we are using Caldera for RIP
Dry 55
Cure 100
Air 45
Vac 25
We changed them to this and tried a couple others to no avail...

I'm posting a pic of one of the areas, but please not only take into account the blue and black areas. There is a glow around it that is pink/purple...

Thanks!

Increase your pass count. If you're on 8 or 10 pass, increase it to 12 pass. The fact that the first part of the print is ok indicates that the heaters need more time to dry and cure the ink on this media. Instituting an inter-pass delay value >0 can help as well (in the Ink Menu > Image Quality Maintenance Menu).

Thank you, any other ideas?
now went with from 10 to 12 pass and .4 delay. helped a little now was OK for about 15 inches and less white specks

I would create a new linearization with lower ink limits. Also make sure you are not overdoing the light inks. Back them off to no more that 20% in the quarter tones and 0% above 70%. You can test this with a quality control target before you make a profile and back the total ink off even more if you are still getting coalescing of the ink.

What are your ink limits on the profiles your using or testing now?

I am using the generic profile. Linearization ink limit was set to 150% Have to bear with me, I'm new at making/modifying profiles

My settings are:

Dry 55
Cure 105
Vacuum 25
Air 35
Total Ink Limit 180%

You're welcome to try my custom profile. I've learnt a bit since making it so I'll probably do a new profile when I get a chance, but it still seems to work quite well. I tried to upload it but it's too large (even though there's meant to be a 100MB limit). Send me a message and I can email it to you.

Thank you for the offer, but I ended up using 24uni pass and got it to work for the wrap I was printing.
