Printing and packaging can be tough because you need to make sure everything looks bright, stays protected, and is safe for the environment. That’s where aqueous coating comes in!
It’s a clear, water-based layer that makes prints look shiny or matte while keeping them safe from scratches and damage. Plus, it’s eco-friendly, which is great for the planet.
In this blog, we’ll explain everything you need to know about aqueous coating. We’ll discuss how it works, the different types you can use, when it’s best to use it, and all its benefits.
Whether you want to make your prints look amazing or protect your packaging in an eco-friendly way, this blog has all the details you need!
What is an Aqueous Coating for Printing and Packaging?
Aqueous coating, often called AQ coating, is a clear, water-based varnish applied during printing. It helps printed materials look better and protects them from damage.
This type of coating is especially popular in the printing and packaging industries because it dries quickly and is friendly to the environment.
Purpose of Aqueous Coating
The main reasons for using aqueous coating include:
- Protection: Aqueous coating acts as a protective shield against scratches, fingerprints, and scuffs. It helps keep printed materials looking new and fresh, even after they are handled many times.
- Aesthetic Enhancement: By adding either a shiny (gloss) or dull (matte) finish, aqueous coating can make colors appear brighter and give packaging a more attractive look. This helps products stand out on store shelves.
- Eco-Friendliness: Because it is water-based, aqueous coating is non-toxic and safe for the environment. It is a good choice for companies that want to reduce their environmental impact, especially for packaging that comes into contact with food.
Aqueous Coating Process (How to Apply)
Applying aqueous coating involves several key steps, each important for getting a perfect finish:
- Preparation: First, the printed sheets are prepared to receive the coating. This ensures that the surface is clean and ready for the coating to stick properly.
- Application: The coating is then applied over the entire sheet, which is called a “flood coat.” Special machines are used to make sure the coating spreads evenly so that no areas are left uncoated.
- Drying: Once the coating is applied, the sheets move through a heated air system that quickly dries the water part of the coating. This leaves behind a thin, protective layer made of polymers, which creates the final finish.
When to Use Aqueous Coating
Aqueous coating is a great option for different kinds of printing and packaging needs:
- High-Quality Prints: It is perfect for prints where a shiny or vibrant finish is desired, making the colors stand out while also offering protection.
- Packaging That Requires Folding: The coating is flexible, which means it works well for packaging that will be folded or creased without cracking or peeling.
- Eco-Conscious Products: Brands that want to show they care about the environment often choose aqueous coating because it is safe and eco-friendly.
Types of Aqueous Coating
Different types of aqueous coatings create various finishes:
- Gloss Aqueous Coating: This coating gives a shiny, reflective finish that makes colors look deeper and more vivid.
- Matte Aqueous Coating: A matte finish is non-reflective, giving printed materials a more subtle and soft appearance.
- Soft Touch Aqueous Coating: This type adds a velvety texture that feels smooth to the touch, giving materials a luxurious feel.
Benefits of Aqueous Coating
Using aqueous coating has many advantages, including:
- Fast Drying: Since it dries quickly, it helps speed up the production process, making it easier to complete projects faster.
- Durability: Aqueous coating makes printed materials more resistant to wear and tear, keeping them in good condition for a longer time.
- Cost-Effectiveness: It is generally less expensive than other options like UV coatings or laminates but still offers strong protection and visual appeal.
- Environmental Safety: The coating is easy to recycle and breaks down naturally, making it a smart choice for eco-friendly businesses.
Comparing Aqueous Coating with Other Options
Here’s how aqueous coating stacks up against other common options:
| Feature | Aqueous Coating | UV Coating | Varnish |
| Base | Water-based | Chemical solvent | Water or chemical |
| Application | Flood coat only | Flood or spot | Flood or spot |
| Drying Speed | Fast drying | Instant drying | Longest drying time |
| Yellowing | Less likely | Does not yellow | May yellow |
| Finish Options | Matte, satin, gloss | Matte, gloss | Matte, satin, gloss |
While aqueous coating is versatile and environmentally friendly, UV coatings offer durability and are better for specific applications that need spot coating. However, aqueous coatings are often chosen for their flexibility and low environmental impact.
Conclusion
Aqueous coating is a key part of modern printing and packaging processes. Its combination of protective qualities, visual enhancements, and eco-friendly properties make it a popular choice for many businesses.
