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

Run numbers, also known as dye-lot numbers, indicate the specific batch in which a wallpaper was printed. Each batch may have slight variations in color or pattern due to differences in production, even if the wallpaper design is the same.

Why do they matter?

Run numbers are important for ensuring consistency in your wallpaper project. If you use rolls from different run numbers, the color or pattern might not match perfectly, which can be noticeable when the wallpaper is applied side by side.

How to avoid issues:

• Always order all the rolls you need at the same time to ensure they come from the same run.
• Check the run numbers on the rolls before installation to confirm they match.
• If you need additional rolls later, provide the original run number to your retailer to try and match the batch, though perfect matches aren't always guaranteed.

Ensuring consistent run numbers will help you achieve a seamless, professional-looking result for your wallpaper project.
