Wallpaper pattern and run numbers

A pattern number and dye-lot or "run number" is printed on each roll.

A pattern number identifies a particular design and color way of a pattern.

The dye-lot number represents a particular group of rolls that are printed on the same print run.

Different dye-lot numbers could signal variables such as a possible tonal change of color, a change in the vinyl coating or a change in the embossing process.

Because of this, it is very important to check each individual roll in your wallpaper job to ensure uniformity in color and pattern. It is also important to record pattern numbers and dye-lot or run numbers in case additional rolls are needed to complete a project.
