There are a multitude of printing techniques to personalize your USB flash drive. We can for example quote the pad printing, the serigraphy, the digital UV printing or the engraving. For the laser engraving, it is necessary to order a USB flash drive allowing this printing technique. In concrete terms, we remove material from the top layer of the personalized USB flash drive in small quantities in order to reveal the color of the bottom layer. The logo is thus engraved and the lower color appears. Invented in the sixties, pad printing is an indirect printing process. It consists of using a silicone pad that transfers ink onto the promotional object in order to make the marking. It requires a flat object to make the marking. The digital UV printing, as for it, consists in printing the advertising objects with special inks drying instantaneously thanks to UV lamps. This process is fast and durable over time. Finally, screen printing is a printing technique using silk screens located between the ink and the support. It allows an important deposit of ink guaranteeing an intense color lasting in time but also a good opacity.
