1.how to produce offset ink
Stage 1: Pre-Dispersion (Paste Mixing)
The process begins in a high-speed disperser (HSD) or a double-arm paste mixer. Here, the powdered pigment is combined with the resin and vehicle.
-
Goal: To wet the pigment particles and break down the largest agglomerates (clumps).
-
Process: The powerful mixer creates a vortex, pulling all materials together. The result is a thick, rough paste that is far from smooth but has all the components uniformly distributed. This paste is often called a "chip" or "masterbatch."
Stage 2: Milling (The Heart of the Operation)
This is the most critical step for achieving color strength and fineness. The pre-dispersed paste still contains pigment agglomerates that are too large for high-quality printing. They must be ground down to a microscopic size.
This is done using a series of mills. The type of mill depends on the ink's viscosity and the pigment's hardness.
-
Three-Roll Mill: A classic and highly effective mill for high-viscosity pastes. The paste is fed between a series of three horizontally positioned rollers spinning at different speeds. The tremendous shear force created between the rollers grinds the pigment particles down to a fine, uniform size (typically less than 10 microns).
-
Bead Mill: More common for medium-viscosity inks. The paste is pumped through a chamber filled with tiny grinding media (e.g., zirconia beads). The intense agitation and collision between the beads provide the shear force needed to disperse the pigment.
Quality control technicians regularly take samples during milling to check the fineness of grind using a Hegman gauge, ensuring the product meets strict specifications.
Stage 3: Letdown and Formulation
Once the pigment is perfectly dispersed and milled to the correct fineness, the concentrated paste is transferred to a large mixing tank, often called a letdown tank.
Here, the remaining components are added:
-
Additional vehicles and resins to achieve the final ink consistency and tack.
-
Additives: Waxes for rub resistance, driers to accelerate oxidation, and other compounds to fine-tune the ink's properties.
This stage is where the final ink formula comes together. Large mixers gently but thoroughly blend everything into a homogeneous product.
Stage 4: Quality Control (QC) Testing
Before packaging, every batch must pass a battery of rigorous QC tests to ensure it performs identically to previous batches. Key tests include:
-
Color Match: Compared spectrophotometrically to the standard.
-
Viscosity and Tack: Measured with precise viscometers and tackometers to ensure proper flow on press.
-
Drying Time: Tested on a lab simulator.
-
Fineness of Grind: Re-checked with the Hegman gauge.
Any batch that fails is adjusted and re-tested until it's perfect.
Stage 5: Packaging and Storage
The approved ink is then pumped to packaging stations. Depending on its end use, it can be filled into:
-
Small cans for individual press units
-
Large pails (5-gallon/20-liter)
-
Even larger bulk containers for high-volume printers
The finished products are labeled, palletized, and stored in a controlled environment before shipping to printers around the world.
