Standard Depths



Standard Depths

Because the colour fastness of dyed fabrics varies with colour depth, colour standard depths are necessary. The main range is designated 1/1 Standard Depths (RTT) and consists of 18 colour tones. Additional ranges in double depths (2/1 RTT), and other ranges in lighter colour tones, 1/3 RTT, 1/6 RTT, 1/12 RTT and 1/25RTT are also available.

For navy blue and black, two other colour depths ranges are recommended:
Navy blue/ light and dark
Black and deep black.
