Roland SP-540V VersaCamm printing problem

[meb]

Trying to print a customers job on vinyl. We've tried running LG brand gloss calendered vinyl as well as cast in 54" & 30". The sign is actually just large block lettering that has a gradient fill ranging from dark to medium green tones - pretty simple, not alot of coverage. The customer supplied us with a cmyk pdf. The problem is that no matter which way we turn the design the streeks are still running in the direction that the media is fed. We've tried changing media but it's still printing with faded areas of color. The pattern is not the same in any print and it does'nt seem to line up with the rollers or anything obvious.
Also tried to adjust the heat and vaccum settings but not having any luck.
Maybe it's just time for a service call.
Also preformed a full cleaning just to make sure.

Any other suggestions would be helpful seeing as this job is on a tight deadline. But . . . no pressure . . . ha haha!

Heater Settings along with Profile.

I use the (RIPC)PCV2 Profile in Versaworks with the heaters set to 37, 40, 50

See if this helps at all.

What version of LG Gloss are you printing on?

We're running Visuon intermediate grade. Profile PVC2 cast vinyl ESM

Lg3810 ??

 

[meb]

yep

In that case, the GCVP or MCVP profile should work.

Thank you, I'll give it a try and let you know.

I have had the best luck using the "PCGV" profile. I think that is what it is. I might have a couple letters mixed up. It is the Premium Cast Glossy Vinyl. It works the best on everything for me on my VP-540.

I took a couple of different files and printed them on different media with about 10 different VW profiles each to see what profile looked the best.

Thanks, I'm giving the GCVP profile a try now.

How about the print quality settings?

In that case, the GCVP or MCVP profile should work.

Does anyone use the quality print setting in VW. I found that the quality WAS better but it's too slow to run and uses more ink.

 

[BobbyFosson]

You will always sacrifice one or the other; speed or quality.

I only use the High Quality on clear vinyl/static cling or backlit.

To get the best prints on clear & static cling use the Overprint option (set to 2) and you'll see a much better print when holding up to the light. As a second option you may also double print...both work great for making the prints not look "washed out".
