2. The INK for Y-film  →→USE NORMAL ink for Y-film (without Carbon)

3. The INK for M-film→→USE NORMAL ink for Y-film (without Carbon)

4. The INK for K-film →→Combine C+Y +M ink* to generate the Near-BLACK color and is recommended to make use of 1:1:1 prorortion among C,Y,M.(Any black ink--without Carbon can be used for K-film printing)

5. The INK for index film→→USE ink with CARBON(or to use ink for normal K-film printing that usually contain Carbon)
