Stop light Material Scratch resistance?
Hi All
We have a grenadier and use citro sol inks. On vinyl the resistance to scratching is fantastic, but our roller banner material scratches very easily by draging your nail across gently.
Is this the Norm?
Thanks

Fraid so
WE have a Roland SC540 which is the same machine as the Grenadier we ar currently using Eco sol inks but are moving next week to full solvent, less of the jibber.
Stop light seems to have a non absorbent property the ink seems to dry on th surface as opposed topenetration on normal vinyls and is therefore very susceptible to scratching.
Not what you wanted to hear but our experience.
We are currently r=testing a softer material for bigger pops that looks promising

Hi,
if it is a polyester stoplight media the reason you are experiencing this is that the polyester must have an inkjet receptive coating to make it printable. The inks you get in wide format machines are not aggressive enought to print onto the uncoated polyester.
Because of this, it is tha coating that holds the pigments of ink, not the base material this is why when you scratch the caoting the ink will come with it. This type of system should really be laminated unless your customer agrees to take it unprotected.
