Presto Labels offers 4-color process digital printing with the option to print opaque white ink and a variable black. Opaque white ink provides the opportunity to create unique effects on clear and metallic materials.
Use opaque white ink as an undercoat for colors on clear materials to brighten type and graphics. If you do not back your type and graphics with opaque white ink, the transparent 4-color process UV inks will appear faint and understated when the label is applied. You can also back your graphics with opaque white ink if you are creating an image that is reverse printed and viewed through a clear container.
Print opaque white ink beneath 4-color process colors on metallic substrates to create areas you do not what to be metallic. Print 4-color process transparent colors over metallic areas to create exciting metallic colors.
