Finger marks on PVC (sintra) prints

Hello
I am printing small sintra signs on 1/8" pvc sintra, using LEF-20 printer (UV inks). All the signs have a light gray background color (PMS warm gray 2). Even though I thorougly clean each panel with 99% alcohol right before printing, 1 in 4 prints have finger marks on them, which can be clearly seen as lighter spots near the top. Is there anything I can try to solve this ?

thanks!

Try UV primers. These fingerprints have been there for a long time and embedded in the top layer. So you better prime the surface with a new bonding agent.
