A detailed reference chart ranks each colorant type in 15 categories: cost, throughput, clean-up, wasted colorant, letdowns, changeover times, consistency, metering systems, color control, lead times, availability, storage space, cleanliness, compatibility and simplicity for operator. Advantages and disadvantages of each colorant type are itemized and evaluated relative to corresponding liquid-color characteristics.
