Screen printing and UV printing signs differ in several aspects:
– **Production process**: Screen printing uses a squeegee to force ink through a screen onto the substrate; UV printing employs printheads to spray UV ink onto the sign surface, which is instantly cured by ultraviolet light.
– **Color representation**: UV printing offers rich, vivid colors with a wide color gamut, capable of presenting detailed and realistic images; screen printing has relatively limited color options and is less effective in representing complex gradients and high-precision images.
– **Applicable materials**: Screen printing is highly adaptable to various materials such as metal, plastic, and wood; UV printing is mainly used on flat, smooth materials and has slightly weaker compatibility with materials featuring special textures or complex shapes.
– **Production efficiency**: UV printing is fast and can quickly complete large-scale production; screen printing has a complex plate-making process and lower production efficiency, making it more suitable for small-batch and customized production.
– **Cost aspect**: UV printing requires a significant investment in equipment and has higher ink costs, but the unit cost can be reduced in large-scale production; screen printing has lower equipment and material costs, but the plate-making cost increases the production cost for small batches.
