the roller system is disposed at an angle to the surface of the curing region 803 thus forming a pocket 807 the less reactive gas introduction means 806 is configured to deliver less reactive gas into the pocket 807 in some embodiments of the invention the roller system 805 extends the full width of the printing system 800 likewise in some embodiments the uv light source 809 can extend the full width of the printing system 800 in some other embodiments the uv light source 809 is coupled to the printing system 800 and configured to traverse the curing area 803 in concert with the carriage 804 in some embodiments of the invention the printing system 800 with a reduced oxygen curing region accomplished by using atmospheric barrier films and incorporating less reactive gas introduction is used by choosing either the barrier film application or less reactive gas introduction in a given application for instance in applications demanding a matte finish the application of barrier film will smooth out the peaks and valleys as explained above therefore according to these embodiments a gas introduction method is desired over the barrier film application likewise the barrier film application can be chosen over the gas introduction methods in other embodiments both the barrier film application and the gas introduction methods are used together according to these embodiments a substrate is fed through the printing region 802 and uv curable ink is deposited onto the substrate it is then fed into the curing region 803 thus encountering the less reactive gas subsequently.
