HELP! Window Perf hates HP LATEX

[greysquirrel]

Its not the product its the profile. More specifically the temps associated with the profile. Make a new profile from scratch, ink density may need to be cut back to 90-95, increase passcode and lower your temp. You own a 365 and 560 for one reason...make your own profiles. That iOne attached to the carriage works wonders.

it is posible to give me o profile, for printing windows perf. i use 75 air an 95 temp - but at hafe of material the printhead touche the perf

If your window perf is touching the printheads, put weights on the lead so that it doesnt lift. I use 5 sets of handle magnets to weigh my lead down. Only do it with window perf.

We've been fighting with this issue on our HP 570 for some time as well. I'll report back results after testing some of these suggestions.

We had trouble with perf on our HP Latex 360 for years. After ruining so many prints I finally sat and kept running samples until we cured the problem I don't know if this will work for you but here is what we did:

First turn down the drying heat to 185, test to make sure the ink is dry. For us it is. Some profiles have the heat up as high as 220 and it curls the substrate and causes scratches.
Next turn up the vacuum to 45
Next turn up the optimizer to 25
Last create a new profile at 16 passes.
Check your ink percentage, I believe ours is at 90

That's what we did, have been printing great ever since.

I hope this helps.

I just loaded up some the other day for the first time in a year or so. I wasted 3 prints cause the kid watching the printer didn't realize the material wasn't advancing. Literally just sitting there laying ink in a puddle while the kid writes down what materials were used for the day. Once I got in there and started a print, tugged on it to help it advance, it was just fine. All prints afterwards have been just fine. I've only ever see that happen with perf, but it may be the weight of the roll.

Can someone provide a suggestion of a good window perf to use for the HP 360 and HP 560?

Currently we use Briteline 70/30 and 80/20. They are both terrible partly due to the overly thick liner and just other series of problems.

Once in a blue moon the 60" wide rolls of 80/20 will cooperate but more often than not we have a lot of problems with the material lifting off the platen during printing and the print heads will scrape across the media leaving major defects and heartache in its wake.
The 70/30 is new to us and I should have just listened to the terrible reviews before "going for it". But it was one of the few things available at the time. The 70/30 perf vinyl is separating from the liner while printing and leaves this vein like wrinkles behind across the entire with of media and moves from one side to another. (I'm thinking humidity has gotten to this roll at some point even though it is brand new to us).

PLEASE HELP. Looking for suggestions on perf that works well with the latex printers and holds up well over time.

I have a latex 360 and I started using the briteline last year and I love it. It might be that your heat is too high. ?

I'm unaware of any problems my customers have with Continental Panorama perf on latex. If you send me your UPS or FedEx number I can send you a test roll at no cost.

 

[MarkSnelling]

While I'm at it, the Panorama One perf from Continental is priced very aggressively. We sell the 80/20, 70/30, and 60/40 rolls of 54"x164' for only $391.00. Lately that seems to match the price of other brands' 100 foot rolls.

 

[kkotvas]

We started using General Formulations 50/50 and 70/30 Perf on our 360 and 560. Have not had any issues since switching. We stay away from the 80/20 stuff. That always tends to be a nightmare.

Turn down the heat, the ICC profile they give you is way to hot. Should be about 185 max for the Brightline or it curls and scratches the vinyl coming out of the heaters.

Also 16 pass with interpass delays set manually if needed after it start running, from the manual adjustment on the front screen of the printer.

Weight it down coming out with magnetic strips to give it weight so it doesn't curl and scratch on the heaters for the first 6 or 8 feet, until you can get it on the take up reel, which helps keep tension on the perf, for less problems coming out of the heaters again.

Last, I have found that when we run perf on a cold machine at the start of the day, we seem to have more problems. The problems start as the machine is warming up and curling the perf as it tries to reach operating levels. We try to run something else first, or do anything to warm up the machine prior to running perf.

I hope this helps!

We have used briteline a lot on our latex. The trick is very low heat, and high passes so it can cure properly. That usually fixes any lifting / walking.

It's not so much the thick liner... It's all the holes provide uneven tension when it gets heated and causes it to buckle.

Our goto in panorama window perf though. We run rolls of that without any head strikes or rubs at all. It also has a longer lifetime than most window perfs

Youre running the Briteline on the Latex with no problems? What config are you using? 60/40, 70/30?

Thank you. Those are all great suggestions and observations. Are you running a 360, 560 or what?

 

[kkotvas]

Running window perf on HP560 I found that it important to use the take-up reel to keep tension on the material so it wouldn't buckle under the heaters. I would just stand there pulling on the perf to keep tension until I could attach it the take-up, or just feed out a couple of feet and attach it before starting the print if you are not too worried about wasting material.

Do you have any weird issues with your 560? Ours has always printed very slowly and I cannot for the life of me figure out why. It prints at nearly half the speed that our old 360 prints at. No matter what media profile/pass # we are using. Its always just slow as hell. The carriage is jerky and it almost always acts like there is a inner pass swath delay set on it. But that option is always set to 0. So there should NOT be any delay.

 

[kkotvas]

On my 570 we run Magic Broad view 60/40 and have never had an issues.

Do you have any ongoing issues/quirks with your 570? Our 560 has always printed very slowly. Like half the speed that our 360 prints at. And it doesn't matter what profile or material I am using. Its always slow/delayed. We've had ours for 5 years and its never been faster than the 360 which it should be. But it can't even keep up with the 360!

 

[kkotvas]

We use Signmax 60/40 on our 800, and our 560 before that and the 360 before that.
Attaching to the take up reel is a must though.

You have run both the 360 and 560? What is your opinion on them? Any major differences aside from the take up reel configuration. Our 560 runs super slow when compared to the 360. The square footage output per hour is often half that of the 360. It doesn't matter which profile or media or pass # we are using. Its always slow/delayed.

 

[kkotvas]

We have had that problem. Briteline likes to curl and cause head strikes and also hits the top of the heater and comes out with defect mark from the ink not being dry and hitting the top of the heater.

Since then we use General Formulation Windowmark 270 70/30. Use their ICC Profile. What a difference! This is usually for storefront flat panel window perf installs.

For vehicles, we use clear focus 50/50, never a problem.

I hope this helps.

Yes I agree the GF 270 works great. We switched over to that a few years ago and have not had the same issues since.

 

[kkotvas]

I have a question about this. what's the color saturation supposed to be?

Are you asking what the percentage amount should be for the perf?

 

[kkotvas]

so first question...you have a 560 why use a canned profile? you paid for a printer with an eye one...make one. If using a canned profile use any adhesive vinyl profile...and a minimum re-linearize the profile, set ink density to eight 80 or 90, start with heat temp at 208 degrees...you may need to lower...12pass mode..

Whats wrong with a premade profile? Are you saying its better to just start with one of the generic profiles that are already installed on the 560 and tweek it from there?

 

[kkotvas]

Having the same issues with the Briteline 70/30 on my HP Latex 800W. Been trying to run 18pass on low heat with an interpass delay and it will be good until like the last foot or so where it will lift from the liner and get a head strike. So disheartening because for all intents and purposes it seems like it's running fine then headstrike right at the end of the print. Banging my head against the wall over here lol.

I can totally relate to this! #PRINTLIFE
