Another advantage of matte varnish is its ability to reduce glare and reflections, which can be helpful when the packaging needs to be viewed under different lighting conditions.
For example, matte varnish is often used on packaging for consumer electronics to reduce glare and make the product more visible in store displays.
Matte varnish is also a versatile option that can be used on a variety of substrates, including paperboard, plastic, and metal.
It can be used for various packaging applications, such as food and beverage packaging, cosmetic packaging, and luxury goods packaging.
However, one downside of matte varnish is that it can sometimes be prone to scuffing and may not hold up as well over time as gloss varnish.
Additionally, matte varnish can be more challenging to apply consistently than gloss varnish, which can make it more expensive.
Soft-Touch/Satin Varnish
Soft-touch varnish, also known as velvet or suede varnish, is a specialty type of varnish that creates a luxurious, tactile finish that is soft to the touch.
It is a popular choice for packaging designers looking to add a premium feel to their packaging and create a memorable unboxing experience for the consumer.
Soft-touch varnish is often used for high-end cosmetic, fragrance, and fashion products, where the packaging is an essential part of the overall brand experience.
One of the key benefits of soft-touch varnish is its ability to create a tactile sensation that engages the senses of the consumer.
The velvety finish creates a pleasant and memorable unboxing experience that can leave a lasting impression on the consumer.
This effect is particularly important for luxury brands that want to create a sense of exclusivity and sophistication.
Soft-touch varnish can be applied to a variety of substrates, including paperboard, plastic, and metal, making it a versatile choice for many packaging applications.
It is also available in a range of colors, from neutral tones to vibrant hues, allowing packaging designers to create unique and eye-catching designs.
In addition to its aesthetic benefits, soft-touch varnish also provides a protective layer to the packaging, making it more resistant to scratches and other types of damage.
It can also improve the durability of the packaging by providing additional strength and rigidity.
However, one drawback of soft-touch varnish is that it can be more expensive than other types of varnish, which can be a concern for some packaging designers.
Additionally, it can be more challenging to apply consistently, which can result in variations in the finish.
The Varnish Process
The varnish process in packaging involves several steps to ensure a smooth and even application.
First, the packaging material is printed with the desired design using ink. Once the ink is dried, the varnish is applied using a printing press or a varnishing machine.
The varnish is spread over the surface of the printed material using a roller or spray nozzle, depending on the type of varnish used.
The varnish is then cured or dried, usually using heat or UV light. This process hardens the varnish and creates a protective layer on the packaging material, enhancing its durability and longevity.
The end result is a beautifully finished product that is not only visually appealing but also offers protection against environmental factors such as water, scratches, and smudges.
