Application of Modified Grass Seed Oil in Offset Printing Ink

The modified grass seed oil is used in offset printing inks, so that the ink shows a good printability and obvious economical use, and its performance indicators are in line with offset ink standards. The test data shows that the modified grass seed oil is worth promoting as a connection material of offset printing ink.

Modified grass seed oil performance indicators:
Appearance: yellowish, clear and transparent Color: (iron-cobalt method), ≤ 12th Viscosity: 1400 mp.s/35°C
Acid value: (mgKOH/g)≤1
Fineness: ≤5μm
Acceptability:>50 (times)

Modified reference formula of grass seed oil for offset printing ink:

Medium yellow ink formula Magenta ink formula Sky blue ink formula aluminum oil 24 32 25
Resin oil 30 24 31

Conclusion: All the data show that highly-polymerized modified grass seed oil not only has excellent compatibility with conventional resin oils, but also has excellent performance indicators after being made into finished ink, and the price is lower than the original old formula. 15%. According to related data, currently offset printing inks account for about 40% of total printing inks, and this proportion will not change much in a relatively short period of time. The price advantage of modified grass seed oil will be obtained in the fierce market competition. The development of large-scale promotion of the application of modified grass seed oil in offset printing ink is also imperative
