Problems Roland Vg3 cyan

[filipa leite]

Good morning group
I need some help, my roland since I bought it the cyan has never come out uniform, it always comes out scratched, although the technician has already done numerous alignments and the nozzle check is perfect, a technician told me about a failure of the roland, due to the cyan paint being too abrasive ruins the head, have you had the same problem?
I am also having problems with the black on a vinyl that I use, for the motocross stickers, the black is not uniform. Note if there are always white spots on the vinyl, what could it be? lack of temperature? or the profile? or another problem? I really appreciate your help!!

Do you have pictures of this, as well as the nozzle test?

the blue one cannot be seen through the image, but I send the black one

Have you played around with profiles, heat, speed, uni vs. bi - directional? Also that photo is very blurry and hard to make out. Would you also have a nozzle test?

 

[filipa leite]

black only looks like this on a specific vinyl, on generic vinyl it looks good, it looks better with speed than with quality but my biggest problem is the cyan
the print is not regular, it always has scratches as if it were problems in the head, but the nozzle checks are perfect

Doesn't really look like there are any issues with the nozzles. I'd need to see a photo of the cyan to know for sure, but you might just need to play around with settings if it's only that one media that is causing issues. Also, are you certain that media is compatible with Eco-Solvent?

When you say scratched, do you mean banding? Cyan seems to be a problem with newer Rolands in my opinion. I think the problem is caused by the damper.

No, cyan is a problem on all vinyls


The problem with the black is that it happens on the vinyl of susbtance and yes is conpatible, but i put ir on standard instead of high quality and i put the temperature Higher and it improved

Yes Banding, i'll look INTO the damper issue then

Its not the dampers it took all new ones

Then the head probably needs changed to correct it. Even as the nozzle check looks good. The head can still cause this.

My VG2 printed great black on just the Generic Vinyl profile but on the VG3 Generic Vinyl Profile the black is very Dark Grey with tiny little white specks still visible...
As ushe 3M doesn't have a profile for my CMMYKLKORGR inkset (use mostly 180c) so I found/am using the Arlon Graphics LLC Fusion Wrap profile and the black coverage is nice and even...its not quite as thick as the VG2 black coverage but acceptable till I do more testing...try the Arlon Profile, the ink coverage was totally different than the new Generic Vinyl profile.

the problem is the colors, we work a lot with specific colors because of the plastics on the moto, I've tried other profiles and I never managed to get the colors I wanted. Do you think that if I make a profile from scratch I will solve the black problem?
