Wrinkled pop-up banner solution?

[MGB_LE]

We use lots of this material on our HP Latex 570 (Ultraflexx DSS 12oz. blockout banner) but we're having issues with wrinkling, possibly due to heat. My operators are saying with less heat, the ink doesn't dry.

How can we improve output?

turn down the temp, but turn up the fans, and maybe add a slight inter-pass delay.... basically give the Untraflex a cooler environment with a little more dry time. (okay, I am printing the Ultraflex on a 700w, so your controls may be different, but I think it should be very similar....) run some test patterns to see... I run density tests and find that I can get better results with 80-90% - use as little as needed to make accurate colors. But the less ink you use, the less ink you have to let dry.....

Or turn down the temp and turn up the passes.

Try Synaps. It is AWESOME. Latex approved. Lays perfectly flat in a banner stand (or when hanging). If you can't find anyone down in Texas who stocks it, I sell 36"x200' rolls for $243.42 for the 8mil. It is a synthetic media that feels like a polyester.

Synaps is great stuff, and nekoosa ships sample rolls for free to try it out.

Or turn down the temp and turn up the passes.

I had similar results with the Synaps as OP on an HP Latex 315, but BigNate and JBurton are right on - just gotta reduce heat and increase passes.

Hey guys, what profile are you using for the Synaps? Hp 700w doesn't seem to have the profile,

Here's another thread with some more helpful info:

Alpha Paper cockling in HP 315 no matter what I try

What worked for me was just cloning the Synaps profile and running at 20 pass, 80%, bi-directional, 160 degrees.
The stock PP/PE Film profile should also work with the same adjustments.

We've had the same issues on our HP 335, we lower the temp as far as it can go to correct it. I think we might have adjusted the vacuum also.

Shouldn't bee too much issues with temps on L700. So on that front I image even generic works if color looks good.
