Application of Modified Grass Seed Oil in Offset Printing Ink

The popularization and application of modified grass seed oil in offset printing ink will apply modified grass seed oil in offset printing ink, so that the ink shows good printability and obvious economical use. Its performance indicators are in line with offset printing 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 index: Appearance: slightly yellow clear and transparent color: (iron-cobalt method), ≤ 12th viscosity: 1400 mp.s/35°C Acid value: (mgKOH/g) ≤ 1 Fineness: ≤5μm Acceptance:>50 (times) Reference formula of modified grass seed oil for offset ink: Medium yellow ink formula Magenta ink formula Sky blue ink formula Aluminum oil 24 32 25 Resin oil 30 24 31 Pigment (12 yellow) 10 (51 : 1 Red) 16 (15:3 Blue) 16 Nano Calcium 18 6 10 Drying aid 0.5 0.5 0.5 260 Oil 2 3 3 Grass seed oil 16 16 16 Main performance index of its finished ink: Medium yellow ink formula Magenta ink formulation Sky Blue Ink Formula Color Approximate Standard Approximate Standard Approximate Standard Sample Fluidity 34mm 37.5mm 36.5mm Viscosity 8.6 8.8 8.4 Fixing Speed ​​4 4 5 Gloss 55.6% 51.2% 52.6% Ink Nature Good Conclusion: All data show that the height of the sum is The 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 reduced by 15% compared with the original old recipe. 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 and promotion of the application of modified grass seed oil in offset printing ink is also imperative.
