Roland VS-640
Printed with both heaters full ball
Stock is an avery 4310 520gsm blockout banner material.
Tried with both CMYK and with metallic prints
I find the metallic smudges really easy on all vinyls too.
With vinyl i have tested metallic prints (on vinyl) and after 2-3 weeks of hanging and still smudges easy.
With the banners I had an off cut i printed on. tested it after hanging for a few hours and 24 hours later.
Leaving it another 24 hours and will try again tomorrow night
So far
Metallic Smudged easy both times
the cmyk wasnt as easy to smudge, but did smudge both times... took a bit of rubbing though.
