What are "run numbers" and why do they matter?Updated 4 months ago

Each time a specific color design or wallpaper pattern is produced, it is given a run number or lot number. Although most people never need to know the lot number, if you run short of wallpaper to complete your job, it is best to order your wallpaper from the same run number for the best color match. If for some reason, the wallpaper is no longer available in your run number, you can use any of our press runs to finish the job. But for optimal results, keep the unmatched run on a single wall, trying not to hang two long strips of two different runs together, because although our color matchers are some of the best in the world, it is impossible to achieve an exact match from one run to another.
