UV OPV nthawi zambiri imatanthauza ma varnish opangidwa ndi UV overprint

UV OPV nthawi zambiri imatanthauza ma varnish a UV overprint (OPVs), omwe amagwiritsidwa ntchito posindikiza ndi kulongedza kuti awonjezere gawo loteteza komanso lokongola kuzinthu zosindikizidwa. Ma varnish awa amachiritsidwa ndi kuwala kwa ultraviolet (UV), zomwe zimapereka zabwino monga kulimba, kunyezimira, komanso kukana kukanda ndi mankhwala. Nkhani zazikulu zaposachedwa zikuphatikizapo kupita patsogolo kwa ukadaulo wa UV OPV pa ntchito zina mongaMakina osindikizira a HP Indigondi kusinthasinthama module a photovoltaic (PV), komanso kuyesetsa kukonza kukhazikika kwa ma prints ochiritsidwa ndi UV.
