Most of the Derprosa films mentioned above can also be printed on using UV screen printing, which is a more appropriate printing method for smaller batches because of an easier initial setup process. For certain brands which may have their own trademarked colors to print on polypropylene films, screen printing may even be necessary. As we mentioned above, some colors do not have a CYMK equivalent, and thus color matching is easier using screen printing. Although many of Derprosa’s metallized films provide a metallic effect even without using metallic inks, screen printing is necessary if you do choose to print with metallic inks. Fluorescent inks are also an option that is only available through screen printing.
Like all things, however, screen printing has its drawbacks. Solid colors do not print as vibrantly as they do in offset printing and high resolution photographs may lose some of their quality because screen printing has an inherently lower line screen (lines of halftone dots per inch) than offset printing.
As each printing method has its own unique advantages and disadvantages, the decision to choose one over the other is highly personal and depends on your particular graphic arts or packaging design project. But know that, whichever printing technique you choose, all printable Derprosa polypropylene films will work with your choice. Just be aware that some films (notably the metallized ones) are printable only through offset oxidative and not offset UV, and that the offset oxidative method must be specific for non-porous materials like polypropylene.
