Hi amgd1972
please confirm, are you printinng a UV coating in line over conventional drying inks + matt varnish.
I worked at James townsends in the UK for 13 years, they are label producers for the food and drinks industry. A lot of the work was UV. Trying to understand how you printing this, Is the UV coating drying ok but not key-ing to the print? is it drying in some areas and not others . what have your suppliers said to you.
It sounds like gas ghosting, where the solvent(gasses) of the ink and varnish from the drying process have not had chance to evaporate off before being sealed in by the uv coating. the obvious answer there would be to run the job then UV coat the work after it's had time to dry, this is'nt cost effective. also worth remembering that the UV coating will still need to post cure even after going through the lamps,(maybe this has improved since i last used these coatings). hope this helps a bit. let me know what you think . regards john h
