Anyone have an idea what causes this?

It looks like a banding, but it's only doing it on one side of the print. printer is Mutoh XJ 1682SR. media is IJ180MC-10. Humidity is at 40%. I have tried different weave patterns setting too. Thanks for looking.

Looks like starvation. Possibly not fast enough signals somewhere along the lines.

To me it looks like the vinyl wasn't laying flat at that part. Or the roll is damaged and smashed at that spot. Try different roll?

Put it on Fine printing with high wave.

you mean data transfer or ink starvation?

that's what I did and it seems like it is a damaged roll. thanks!

ill give it shot. thanks. that run is at I-weave ex3 on uni-direction.

Usually, if the signals going to the printer at some point get slowed down for whatever reason, it won't send a great deal of things being printed.

This is gonna happen, if your rolls are not stored properly. Usually it goes the opposite way under those conditions.

thanks for all the info.

ill look into that too because my data goes thru the network before it gets to the printer.

we have our rolls sitting on a pallet. it could've been damage in transport.

Is it happening in a consistent pattern? If it is it may be the material but is put money on ink starvation.

That is a large field of a solid color and can happen at your faster print speeds.

Out of the box profile(s) or have you built your own? Linearized your profiles?

printer is running at slow head speed. it is on consistent pattern about 10" apart. profile is built in house G7 certified.

Looks like the media isn't all the way flat on the left edge. Does it do it consistently through out the roll or randomly?
Check and make sure the vaccum is working when the machine is printing.
If it's the media then raise the print heads and see what that does.

Similar thing happens to me when the media does not stay flat. Usually with the monomeric vinyl, wrong temperature, high humidity or just the vacuum lost its suction.
My printer is a Mimaki.

I've seen this on my Roland's before. Seems to happen more on the side of the printer furthest from the capping station. That's all I got

 

[ToneCustomSigns]

I have that same thing happen on Arlon SLX on my Mutoh 1624. Only on that material though. I haven't been able to figure out why.

My guess would be roll problem or tension issue, or maybe encoder issue. I've never ran a 1682 but if they're like other mutohs I assume there are encoder strips for the carriage and advance. I don't think think that is the problem but cleaning those encoders is an easy rule out.

Thank you for all the response peeps. it actually is a defective media. I changed roll and its gone..
