The apparatus and process disclosed relates to the application of a pattern on a material such as roof covering or siding where the surface is coated with media to create a three dimensional pattern. The 3-D pattern is created in multiple detailed steps so that the width of the pattern can be of an adjustable size in order to make the pattern more diverse and variable. The apparatus and method disclosed herein utilizes a series of applicator units which apply media in a pattern or without a specific pattern onto the material. The first applicator unit is designed to be the master applicator unit. Each applicator unit can include a separate drive or motor. The apparatus and process disclosed incorporates one or more slave applicator units. These slave pattern applicator units with slave pattern applicator rolls are synchronized to the master pattern applicator roll located in the master applicator unit.
