Things You Should Know About Industrial Ink Additives

Ink additives are a vital part of the production process resulting in industrial inks. The unique formula that each ink comprises of is due to these additives.

This allows for diversity and variety in different printing applications present in the publishing and media industries, respectively. In the industrial printing field, just the right combination of ingredients is required to produce the correct formula to make the inks appropriate for their destined uses.

While the amount itself isn’t considered significant in any aspect, its existence is still crucial and therefore appreciated.

As the industry changes and develops with new technologies, additives do as well. Needham Ink is at the forefront of the ink manufacturing industry. They regularly improve to keep up with an evolving industry that’s always working on getting better.

Now that you know the definition of an additive, let’s take a look at the different groups an ink additive could fall into, depending on its makeup:

  • Dispersing and Wetting: the strengthening of pigments is important in an ink formula. This results in a better separating of solid particles. Without the additives, it would be much harder to achieve this.
  • Surface: additives designed to improve surface quality help to make cleaning easier in general. This is done by improving imperfections of the surface.
  • Rheology: it’s important that when storing something, it can last for a long time. This group of additives molds itself to the system of the ink itself. This is not dependent on it being solvent-free, these two factors are mutually exclusive. There are a variety of materials that can be used in this instance, including acrylic thickeners and clay.
  • Defoamers and Air-Release: bubbles aren’t welcome in industrial inks, and manufacturers are always looking for ways to reduce the likelihood of this. Additives like defoamers are capable of reducing the probability of bubbles dramatically.
  • Wax: wax is a key ingredient in certain additives as it helps improve the quality of the surface in ink. There are specific factors to take into account when using a wax additive. These include chemical basis and melting point.
  • Processing: processing additives are the most important category in the additive family. This is because this grouping comes with a high number of solutions for getting good results, resulting in a high-quality industrial ink. Improvements made through processing additives include being able to boost its mechanical strength, reducing emissions, and improving the quality of the release properties.

When your work involves the use of industrial inks, it is important that you choose the correct additives for the job at hand.

Of course, this is going to depend on which result you are hoping to achieve. Each additive is capable of completing a different task and has a different role. Because they can all alter the composition of the ink chemically, it’s imperative that you know you’ve got the right additive before you use it.

The list above includes all the major groupings that are practically applied in the consumer goods ink industry.
