Offset Ink

Offset ink is also called offset printing ink. Its varieties include offset resin ink, offset bright ink, offset four-color printing ink, offset quick-fixing ink, offset bright quick-drying ink, offset sheet-fed ink, offset rotary press ink, offset rotary thermosetting ink, offset printing iron ink, offset plate Printing iron retort-resistant ink, offset plastic ink, offset light curing ink, etc.

There are many types of offset inks, but the requirements for the machine are mainly three-roller and dual shaft mixer for production. We provide the entire process production line, and also provide the ultimate after-sales service.

Offset ink needs a butterfly mixer, twin shaft disperser (high speed and low speed), high viscosity bead mill, and hydraulic three roll mill. Why should need two kinds of mixer machine? Pre-mixing and then adjusting mixer after add additional chemicals.

1. high speed viscosity mixer for offset ink, which is mainly used for offset ink, which adopts the butterfly blade the shaft can lift up and down while mixing materials, the materials can be dispersed at various angles; In addition, we also match the clamp on the high-speed viscosity mixer for offset ink, the mixing tank can be fixed well when mixer for offset ink running, which make the operating stable and high efficiency.
2. Dual shaft mixer for offset ink was be adopted next to the high viscosity mixer for offset ink, high speed and low speed can run separately, the low-speed blade rotates around the tank side, and the Teflon scrapper can clean the tank side very well, then the high speed running when the low-speed blade running, which mixing and dispersion are running together, so the shear force is higher.

3. Dyno mill for offset ink, which is designed for high viscosity material;

1). Auto-control pressure for the inner chamber, which makes the grinding effect better,
2). Double cooling for both rotor and stator, can make the material temperature reduce when operating.

3). Grinding medium adopts 0.8-2.5mm, which can make the discharging material reach 5-15um

4). Higher sealing of double mechanical seal, which avoids the material leaking when operation.

4. After the dyno mill for offset ink, we suggest matching the extruder for offset ink, as the offset ink is with high viscosity, transferring the high viscosity material to three roll mill is not convenient, the tank of the extruder for offset ink can be lifting and downing, and there’s discharge port at the bottom side of extruder tank, which can adjust a suitable place to feeding the material to the three roll mill, which is more convenient.

5. Three roll mill for offset ink match after the dyno mill is perfectly matched for offset ink production. Franli three roll mill with hydraulic system, which has high efficiency for grinding, and the three rolls are with frequency control, which can fit different viscosity of materials. Controllable pressure and gap of rolls, make the adjustment accuracy to keep the stable discharging.

(note: some customers will add one more three roll mill for grind one time, which can make the offset ink color more bright, this is popular in the Chinese market)
