When you want to create a memorable product experience, you need to give equal attention to its packaging. Its success does not just involve a great design but also the quality of the packaging and how well it stays even after it has been handled and transported.
One of the most overlooked aspect of this, is what type of coating is being used. This factor is crucial, as a well-chosen print coating can make or break the look, feel, and durability of packaging.
The most popular and utilized coating method in the industry is AQ coating. However, mostly people gets confused between aqueous and UV coating because of their somehow similar properties. Lets explore the major factors that differentiate it with other techniques, and how it is applied.
What is AQ (Aqueous) Coating?
In the world of packaging and printing, aqueous coating is a water-based, transparen solution of polymers and other resins that provides a protective layer ober printed materials.
Its non-toxic nature, and the fact it has water in it, makes it environmentally friendly. This method is highly versatile, and cost-efficient as well, which is why it is widely used for a variety of applications.
Key Features
- The fact that this coating is primarily made of water, a natural resource, makes it safer and less harmful ti the environment. When compared to the other techniques, that use harsh chemicals, it is a preferred choice.
- The water in its solutions evaporates quickly, allowing the coating to dry fast and makes the production faster and more efficient.
- It also come in different finishes like gloss, matte, satins and soft touch. Each of these types has its unique look and feel. The distinct appeal and aesthetics of every finish is versatile enough to suit multiple industries.
- AQ coating is safe to use on a range of products, including cardboard boxes, rigid boxes, brochures, flyers, visiting cards or any other printed materials.
However, it’s essential to note that AQ coating is not waterproof. It can resist moisture to an extent, but it doesn’t hold up well when exposed to liquids over extended periods. This makes this water-based coating ideal for items like brochures, boxes, and posters but less suitable for high-moisture applications.
Why Use Print Coatings?
Before diving into aqueous coating in printing, let’s address an important question: Why bother with a print coating at all?
- Protection
Packaging undergoes a lot of handling—from production lines to transportation and store shelves. Coatings protect printed materials from scratches, fingerprints, and scuffs.
- Visual Appeal
Different coatings can give your packaging a unique look. Some add a high-gloss finish that enhances colors, while others offer a softer, matte effect for a more understated look.
- Brand Perception
Premium coatings can give your brand a high-end appearance, which could appeal to customers and increase perceived value.
But not all projects need coatings. Items like greeting cards, where people might want to write on the surface, usually skip coatings, as they can make it difficult to add handwriting or notes.
Types of AQ Coating
To better understand this type of coating, let’s look at the different types available and what each offers:
1. Gloss AQ Coating
- Provides a shiny, reflective surface that enhances the vibrancy of colors.
- Suitable for packaging where you want visuals to “pop” and grab attention.
- Commonly used for brochures, magazines, and vibrant product packaging.
2. Matte AQ Coating
- Offers a soft, non-reflective finish that gives a luxurious, high-end feel.
- Ideal for premium packaging or when you want a more understated look.
- Used frequently for luxury goods and professional documents.
3. Satin AQ Coating
- A middle ground between gloss and matte, offering a gentle sheen without too much shine.
- Great for packaging that needs a sophisticated look without being too flashy.
- Often used for product boxes and presentation materials.
4. Soft Touch AQ Coating
- Provides a velvety, smooth texture with a matte appearance and no shine.
- This type of coating gives packaging a premium feel, adding a tactile experience.
- Popular for upscale product lines, book covers, and luxury brand packaging.
Each type of coating serves a unique purpose, and the right choice depends on the desired look, feel, and functionality of your packaging.
Benefits of AQ Coating
Aqueous coating is a popular choice in the printing industry for several reasons:
- Eco-Friendly: Since it is water-based and non-toxic, it produces fewer harmful emissions, making it a safer choice for the environment.
- Cost-Effective: It is generally more affordable than UV coatings or laminates, especially for larger print runs.
- Fast Drying: The coating dries quickly, which speeds up production times and can reduce costs.
- Durability: It protects prints from minor scratches, fingerprints, and scuffs, extending the life of printed materials.
- Versatile: Available in various finishes, AQ coating can be tailored to meet different design and branding needs.
The Process of Application
The application process is straightforward and efficient. Here’s how it works:
- Preparation: The sheets of printed material are inspected to ensure they’re free from dust or debris.
- Coating Application: A special roller applies the AQ coating. This can be done as a flood coating, covering the entire surface, or as a spot coating, targeting specific areas.
- Drying: The coating is quickly dried using a system that blows hot air over the sheets, allowing the water to evaporate.
- Finishing Touches: Once dry, the coated sheets are inspected, cut, or assembled as needed.
Comparing AQ Coating with Other Coatings
It’s essential to understand how this technique stacks up against other popular types like UV coating and varnish. Here’s a quick comparison
| Feature | AQ Coating | UV Coating | Varnish |
| Finish | Gloss, matter, satin, soft touch | High gloss or matte | Gloss, matte, satin |
| Durability | good | Very high | Moderate |
| Drying speed | Fast | Near-instant | Slowest |
| Eco-friendliness | High | Moderate | Low |
| Resistance | Good against minor scratches | Excellent, chemical resistant | Moderate, can yellow over time |
Key Differences
To understand what factors makes these finishes different from one another, you need to consider aspects like:
- Appearance
- Durability
- Environmental Impact
- Cost:
Is AQ Coating Right for Your Project?
If you’re looking for a protective coating that is environmentally friendly, affordable, and versatile, then this coating is an excellent choice.
It works well for many applications, from product packaging and catalogs to business cards and flyers. However, if your project requires maximum durability, UV coating might be a better fit.
Consider it if,
- Your project needs a quick turnaround.
- You want to avoid high chemical emissions.
- You’re looking for a cost-effective solution with a range of finish options.
Alternatives to Consider
- For extreme durability you can also give a shot to UV coating.
- For special effects, you can also use other coating techniques like varnish can be used for selective glossing on specific areas.
Wrapping Up!
AQ coating is a highly effective solution that enhances the durability, appearance, and feel of printed materials. With a variety of finishes and eco-friendly properties, it’s a practical choice for businesses that want quality packaging without compromising on environmental standards.
Whether you’re working on product packaging, promotional materials, or printed goods, AQ coating offers a balance of beauty, protection, and cost-effectiveness. Considering its benefits and easy application, it’s easy to see why AQ coating remains one of the industry’s go-to choices for print finishes.
