Aqueous coating is a clear coating that is made of water and is used in printing and packaging. It can be found on product boxes, brochures, labels, and business cards quite often. It provides a smooth finish and makes prints to be long lasting.
In today’s packaging world, brands want prints that look good, feel good, and stay safe for people and the planet. That is where aqueous coating matters. It is quick to dry, less expensive than most other finishes, and is less hazardous to work with. It is also compatible with offset and digital printing, and that is why it is a favorite choice of modern packaging.
In this blog, we explain what aqueous coating is, how it works, where it is used, and how Blackline Packaging helps brands use it the right way.
What is Aqueous Coating?
Aqueous coating meaning is simple. It is a water-based coating applied to printed materials. The word “aqueous” means water. So, what is aqueous coating? It consists of a combination of water, resins, and minute additives that form a thin protective coating on paper.
Aqueous coating is also a part of the coating that employs the use of water as its primary carrier, unlike the solvent-based or UV coating. This allows it to be used more easily and cleaned in the course of printing. It also has less harmful emissions, and this is important both to the workers and to the environment.
Aqueous coating in printing is also used in packaging and the quality of prints. It enhances the level of color and natural appearance of prints. For many brands, aqueous coating for printing is the balance between performance, cost, and safety.
How Aqueous Coating Works
The process of applying aqueous coating is straightforward and efficient.
- During printing, the coating is applied either inline on the press or offline as a separate step.
- Most offset presses have a coating unit that spreads the aqueous varnish coating evenly across the sheet.
- In digital setups, aqueous coating digital printing is often applied after printing using a coating machine.
- The coating is dried by heat and air once it has been applied.
- The evaporation of water is a relatively short process, and a film is produced.
- This is a quick process of drying and does not need any specific UV lamps. Such a pace is a way of keeping production afloat.
Aqueous coating is compatible with both offset and digital printing. It is bonding well with ink and paper, and that is why it can be relied upon during short-run and big-packaging projects. This is one of the reasons why aqueous-based coating systems are popular these days.
Types of Aqueous Coating
Various finishes have varying looks and feels. The correct type of choice is dependent on your brand and product requirements.
