Grainy colours?

Post by robbo78 » Fri Jan 12, 2018 3:16 pm

Hi, not long had my BN-20 but I am liking it so far. Only issue I seem to have is when printing lighter colours such as the in the image I have attached. Not sure if I’m just being really picky or not but it looks a bit too grainy to me for a £5500 machine?

Is this a settings issue or am I expecting too much? For reference I’m printing onto transparent vinyl with a white bottom layer first.

Thanks,
Rob

Keep your color management setting on "Sign & Display".

I've just changed to this setting and it's much, much worse?

EDIT: Sorry after further comparing it seems to be about the same but does make the colours look more how they're supposed to.

Anything else to try to remove the graininess?

Right I’ve narrowed it down to the white underlay. If I print without a white underlay I don’t get the problem. Obviously this isn’t any good when printing onto transparent media, which is most of the time for me.

How do you do the printing, do you allow the white layer to dry before applying the CMYK?

I usually do the standard one pass method but I have tried allowing the white the dry first but it makes no difference for some reason.

However I have been playing about and have found that if I print in uni-direction the grain isn’t really that noticeable compared to printing in bi-directional, but you can still see the grain when compared with no white ink.

Oh, there's no chance of getting rid of ink flaring up in one go.

Print white layer with "return to origin after print" and then CMYK. A world of difference.
