Have you tried turning the heat up? Or on? That's exactly how my Roland prints when the heat is turned off.
Ok. I'm not an expert, but I can offer a few more tips. Next relevant question would be: are you using Roland brand inks, or a 3rd party brand like Clearcolour? If you're using 3rd party inks, they don't dry as quick so you need to crank up the heat on all your profiles.
If that still doesn't solve it, I would turn down the head speed to 1/2 or 1/3 of the current setting and do another test print, just to make sure it isn't a drying issue. This will make your print head go side to side much slower while printing.
It definitely looks like a drying issue though, so another culprit could be your media profile. A good test for that would be, for example, if you're using Avery matte calendered vinyl with an Avery profile, try the generic Roland matte calendered profile or go find a matte calendered profile from another brand like 3M. If one of the other profiles works better, then your Avery profile might be laying down too much ink.
Open color managment box under matching method in raster setting try saturation and absolute , check box preserve primary color.
What if you use the prepress setting instead of Sign&Display? Is this normal or fast speed you're printing at? Looks like when I print some colors at high speed mode, on some vinyls. Do you have your head setting at low?
Should i keep it under sign and display.. in raster and vector i can eithe rpick saturation or absolute not both.
Just a tip to....keep in mind that if you are cmyk printing to match a solid spray paint color the CMYK color will be completely different indoors vs outside in the sunlight. So if you are color matching for something that is going to be outside you should do your color comparisons outside. If they match indoors then the cmyk won't match the paint swatch outside. The mix of colors is affected by lighting whereas the solid paint - not so much. We have some clients where we have one cmyk and print setting for their indoor signage and a separate one for their outdoor and vehicle signage.

You'll never get the same solid smooth color from your cmyk printer as solid vinyl BUT you should be able to print WAY smoother than what I see in your photos.
Here's a photo of one of our prints:
Media:Trustock intermediate vinyl
Printer: Roland VS-540
Inks:Roland EcoSol
Settings: Versa Works, Generic Vinyl 2

I mean try once raster setting saturation and once absolute see which get you correct color nothing do with vector setting.
RGB : Adobe RGB 1998

Main problem you have that material not absorb the ink well wrong profile cause that try with profiles or bad material try another kind. look at last page in attached file.
we have a vp and that looks like a heat issue (as many have already said) but could also be a profile setting. what material are you using and what profile are you using in versa works?
i have seen issues like that if someone used the wrong material profile. also have you done manual cleanings or maybe change the capping stations.
Were these samples you posted printed in uni-directional? Set up your colors as pms colors if not already. Some RIP softwares adjust cmyk colors. They read pms colors as spot colors and leave the cmyk values alone.
