Manufacturers produce wallpapers in different series. The colours are redesigned for each series, which results in minimal colour deviations between different batches.
For reorders we usually need the production and / or batch number of the wallpaper purchased, because only with rolls that have completely identical coding it can be guaranteed that the colour and structure actually match. You can find the production and / or batch number of your wallpaper on the delivery note, the instruction leaflet of the wallpaper roll or on the label of the product received.
This is particularly important when the reordered rolls are wallpapered directly next to already existing strips (identical wall). If, however, the reordered rolls are to be hung to a new wall, any colour deviations are generally no longer perceptible due to shadow effects in the corners.
