Digital printing and Gravure printing: which one is better?

Let's look at the difference between digital printing and gravure printing.

What is digital printing?

Digital printing does not use printing plates like traditional gravure printing, but uses toners like those used in laser printers or other large printers that use liquid ink for printing. When a smaller number of bags are needed, digital printing is more advantageous.

What is gravure printing?

The gravure printing process is different from digital printing. Unlike the toner in digital printing, in gravure printing, the image is directly engraved on the paper, box or package. Gravure printing is a relief printing process that uses an engraved, usually metal printing plate to transfer the design by rolling it in ink and transferring it to the printing surface. In packaging, gravure printing is most commonly used to print on thin and flexible materials, such as stand-up bags, film materials, etc.

 

Which is right for me?

Both gravure printing and digital printing are commonly used and practical printing methods. Each project has specific benefits, depending on the requirements of the project. When you need a large-scale project to run, gravure printing is your best choice. If the demand is small, you can use digital printing for your solution.

The best part is that as a business, you can meet your needs with one of these two options, but high-quality quality means you can get printed products that can make you look more beautiful!

How does packaging affect the aroma of coffee?

To make full use of the aroma of coffee requires perfect roasting of coffee beans. This work requires time, knowledge and energy. Complex and delicate taste is the characteristic of specialty coffee. This is the purpose of roasters and what consumers want. Therefore, it is absolutely necessary to maintain the taste and aroma of coffee beans.

Therefore, the coffee beans must be packaged in a way that preserves the taste and aroma. If you use incorrect packaging materials and packaging methods, consumers will not be able to experience the promised taste characteristics. What are the problems caused by this? Your brand will be blamed, or your subscription will be lost.

The aroma of coffee can also tell people how fresh the coffee beans are. The more aroma of beans, the fresher they are and the better their taste. It is completely natural for the aroma to disappear over time, but you can still take certain measures to delay the process before then. Correct packaging is one of these measures.

 

When the coffee beans are exposed to oxygen, the aroma of the coffee disappears. When coffee beans are exposed to high temperatures, the oxidation process also occurs more quickly. When warm, the sweetness disappears quickly. But even if the coffee beans are refrigerated, do not freeze them. When it is thawed, condensation will make the beans wet and reduce the quality. Therefore, coffee beans should be stored dry, and should be a few degrees below room temperature, and should not be exposed to the air.

So what kind of packaging should be the best?

Good packaging should protect coffee beans from oxygen, humidity, sunlight and heat. Therefore, packaging with more than multiple layers is required. The innermost layer is preferably made of aluminum because it is the most effective oxygen-proof material. Aluminum can also prevent moisture.

In addition, the packaging must be properly sealed. The packaging bag usually has a vent hole through which CO 2 can escape. The coffee beans will release CO 2 after roasting. Although CO 2 is necessary for the coffee to have a good taste and aroma, too much CO 2 will destroy the quality of the coffee again. The pores allow excess CO 2 to escape and no oxygen enters.

Therefore, a good coffee packaging should include a well-sealed opening method, such as a re-sealable zipper or heat seal, and a degassing valve that can prevent oxygen from entering and can discharge CO 2. It is best to add a layer of aluminum foil to Achieve better results. But considering sustainability, you can also choose recyclable or compostable packaging materials.
