Acid-free inlay paper

High-quality white acid-free inlay paper (300 g/m²), placed between your print and the backing board for extra protection. Being acid-free, it helps prevent your artwork from yellowing over time – ideal for valuable art or delicate papers (standard posters don't need it). Thanks to its weight and subtle texture, it can also sit behind your motif as a clean white border, or as a backing alternative to a passepartout.
