There is no definitive answer to this question since there are many variables that can affect the lifespan of a digitally printed fabric. The type of fabric, the ink used, the printing process, and how the fabric is cared for all play a role in how long the colors will stay vibrant. In general, though, most digital prints will retain their color for several years with proper care. With that said, some prints may start to fade sooner than others, so it's always best to follow the care instructions provided by the manufacturer. If you have any concerns about fading, be sure to contact the company that made your fabric to get specific advice.
