Printing seems Grainy

[ml4cs]

New to large format/solvent printing. I have a Roland SP540i running Liquecolor inks in a 440ml cartridge printing on Oracal 3651 gloss

I read some posts and adjusted print temp to 108 and dry temp to 110

Lighter colors seem to come out grainy, darker seem ok if I print at high quality, also used a few different color profiles in versaworks and kept getting better

My question is will I ever be able to get rid of the grain with Gloss? or would I have to go Matte with Lamination?

Would settings, calibration, ink or media make any difference

Thanks!

Reprint the file in Uni-Direction. If it looks better, you need to do the bidirectional adjustment. See attached. Use the detailed mode.

It depends what you mean by grainy, some profiles are set up for the black to be a 100%K instead of a combination
of CMYK, that gives a printed faux metallic look.
It also depends on what output resolution your profiles are set at; 540 x 720 -720 x 720 - 720 x 1440 -ect.

Please post a clear closeup pic, especially if you can print some small text.

Would settings, calibration, ink or media make any difference.....yes, yes, yes and yes...being new to printing, do yourself a favor and go back to OEM inks

Ran through a detailed bi directional adjustment.

now printing at high quality seems to get rid of the grainy look. I’ll load a couple pictures
