reusing coasters and colour issues

Hi, I have only been do sublimation for a couple of weeks so would appreciate some advice.

Can I reprint over a sublimated coaster? I have a few that didn't work out and was wondering if I can reuse them? Can I recoat or use laminate sheets?

I have got the hang of it now on most images but I am still having problems with images that have a lot of blue or green as they just
dont look right?

I am using ink experts ink, paper and colour profile and have it all set up right as other images are ok.

Appreciate any help.

Thanks

recoating one would cost you price of 10 new ones you would buy new :rolleyes:

Yes you can reprint over a printed coaster....with a UV machine :-)
