High-Quality Equipment for Ink Manufacturing

Inks play a crucial role in printing because their composition suits specific printing techniques and the surfaces they interact with, such as paper, cardboard, wood, textiles, foil, plastic, metal, and leather. The process of manufacturing printing ink is a complex and specialized one, involving the meticulous grinding of pigments to form an ink dispersion that combines resins and stabilizers to attain the desired functional attributes. By grinding the pigments to precise particle sizes, the ink can achieve the necessary color, strength, gloss, transparency, and opacity, ensuring optimal performance for various applications.

Industry Benefits

  • Packaging Inks

    Packaging inks with optimum particle distribution and enhanced stability improve color development and results in smoother ink flow during printing. The result is better print quality with sharper images, vibrant colors, and improved line definition. Additionally, this offers improved water resistance, scratch resistance, and rub resistance.

  • Print Media

    Milling can enhance the bonding of the ink to the print media by enabling superior ink transfer, leading to sharper and more vibrant print outputs. The enhanced consistency and controlled absorbency influence ink drying time and color saturation during printing as well.

  • Nano Pigment Dispersions for Ink Jet

    Nano pigment dispersions for inkjet printing enhance print quality and prevent inkjet printer nozzle clogging. They also maximize pigment yields and provide consistent color results.

  • High-Viscosity Inks

    Grinding high-viscosity inks to a tight particle size distribution benefits the final product by improving the ink’s handling and application during the printing process, ensuring consistent color and a uniform appearance in the long run.

Customers are encouraged to work with our team of experts and run trials to determine the optimal parameters for their product. Furthermore, we offer free initial testing!

  • How can Hockmeyer’s equipment assist in the ink manufacturing process?

    The equipment used during the deagglomeration, dispersion, and milling of the pigments for printing inks makes all the difference in achieving an efficient processing method and the quality of the final product. Through innovative mixing, dispersing, and milling solutions, it is possible to make efficient, consistent, and reliable products.

  • How do you avoid foaming problems in waterborne formulas?

    Avoiding foaming problems in waterborne ink formulas is crucial for improving efficiency and increasing profits. Recirculating vacuum dispersion and milling offer a solution by reducing process times, increasing yields, and eliminating air entrapment.

    The NEXGEN™ equipment line addresses the issue by removing air from the product, ensuring a pure and stable dispersion without the inconvenience of air bubbles in the feedstock. The NEXGEN™ RotorStator disperses the pigment and eliminates trapped air, enabling faster and purer particle size reduction and deagglomeration. The NEXGEN™ Vacuum Recirculation Mill further reduces the pigment’s particle size, resulting in a tight size distribution, ultimately yielding a high-quality dispersion ready for letdown and final ink production.

  • How is ink made for printers?

    In ink manufacturing, pigments are the most expensive component, and selecting and processing pigment is crucial for efficient production. The ink-making process involves two fundamental physical processes—wetting and deagglomeration of pigments and their uniform dispersion in the vehicle, known as dispersion. Milling is the step that reduces the particle size to a specified metric. The quality of the product and its profitability largely depend on optimizing these two processes.

  • What is used to make printing ink?

    Printing ink is available in paste or liquid form and is made up of dyes or pigments derived from nitrogen-rich sources that determine the ink’s color. The ink’s base, called varnish, includes linseed oil or soybean oil, resins, solvents, and other materials and serves as a binding agent to enhance gloss and protect printed surfaces. Resins improve the ink’s binding and adhesion to printed surfaces, and additives, like lubricants, surfactants, alkali materials, and drying agents, are incorporated into the ink to modify its properties for different applications, providing rub resistance, improving printability, adjusting pH levels, and promoting faster drying.
