Need Help UCJV300 white ink alignment issues.

We ran into the same issue, and have moved to printing only out of Onyx thrive and only cutting our jobs on our Summa cutters.

Both rasterlink and the cut feature on the UCJV are quite useless as far as I'm concerned. It took a miracle for cmyk+white alignment or print/cut alignment to work, so we moved on and found other solutions.

Sorry, that's probably not what you want to hear. Hopefully someone has found a way to make these things work but I just ran out of patience and used proven RIP software and cutters to do their jobs rather than relying on software/hardware that seems like it was written by a 8 year old.

 

And I was so close to buying one of these printers! Thanks for the feedback.

 

You need a tech to align the white and the cut you can align.

 

Hi all,

I have to ask why you're letting the printer roll back between layers instead of letting them all print at the same time? The printer is capable of doing a "virtual-stagger" on the heads and you can print up to 5 layers at one time (as shown here )

We've worked extensively with the UCJV300 since they first came out and do date, I don't think we've had a single issue with white alignment. I usually set the white layer in RasterLink to choke by 2 pixels (so it doesn't bleed out past the color), but the alignment when printing simultaneously is so good, it's more force of habit on my part than any kind of necessity.

I don't want to say you're doing this wrong, but... if you're letting the printer complete one layer and then roll back, you're probably doing it wrong. I don't have Rasterlink up right now, but there is a checkbox that determines whether the printer rolls-back between layers or does them all at once.

Hope this helps

I definitely wouldn't discourage you from getting one of these. It's a great machine, and has performed very well for us. My complaints are really just with Rasterlink (easy fix if you're already running Onyx or willing to dish out some more $$ to upgrade) and the print / cut registration.

To be fair, when we first got the machine a year ago we were absolutely swamped and needed it running immediately. I realized there were issues with Rasterlink and print/cut accuracy and quickly found another solution.

I'm sure, as stated above, there are ways to get those things corrected and working properly.

 

Make sure your take up isn't pulling too hard. You can adjust the clutch to loosen it a bit. If the motor pulling the vinyl back has too much tension to pull against, it will throw off the feed. Also, make sure your vacuum is set to the highest settings so you don't get the rippling. If you are printing on material that isn't the full width of the printer, put transfer tape over the part of the platen you don't use so the holes are covered and you will get more suction as well.

 

I think the default settings for the pinch rollers when it cuts is to use the 2 outside rollers only. Make sure they are in the right spots otherwise you get tracking issues. I have had that happen before.

Now, I use all the pinch rollers during the cut. Since its UV, the ink cures immediately so no issues and no tracking issues. However if you have clear ink, sometimes you can see the roller marks it kind of smears the ink. Usually have to let it dry a bit more. Typically that happens on short jobs that you print and cut right away

 

Try to cut using marks. It is far better.
