Hi , has anybody got any tips on Flexo Printing on the following material - A matt white uncoated woodfree printing paper composed of 95% of sugar cane fibres and 5% of hemp and linen - we have a big job on and the UV Inks just soak straight in leaving the print looking washed out and faded , we have tried sealing the surface with laquers / varnishes first but it makes hardly any difference, I think the surface is just to pourous....any advice appreciated , thanks.
