Tile Design & Faces Tile Randomness/Variation R2-Slight Variation R1-No Variation R3-More Variation R-4 Most Variation Each tile design is printed with some variations on different individual tiles. Variation may be in grain structure or how texture appears in the design. This gives a natural look to the surface where tiles are laid and avoids a small repetitive pattern. The number of variations in a design are called faces of a tile Randomness is a parameter to indicate the scale of difference in different faces of a tile design. Small variations in faces are indicated with R1 and high variation by R4 F1 F3 F4 F2 F1 F3 F4 F2
