With other technologies, you might need to over-laminate to achieve extended durability, which adds a step to the production process. Outdoor products and signage are more susceptible to vandalism as well. Other technologies may require you to over-laminate to achieve anti-graffiti characteristics, which is again an added step in the production process.
Since sublimation is a sub-surface decoration process, sublimation panels (such as from Duraluxe or ChromaLuxe) do not have to be over-laminated for either extra UV durability or anti-graffiti. It is all included in the coating, which saves time, labor, and costs for the finished product. Since sublimation is digital, your images can be much more impressive than other imaging technologies. With signage, you only have so much room to get your message across. And like they say, “A picture is worth a thousand words.” Great images can help you convey a better message in a smaller area.
