Common methods for testing the properties of water-based inks

The method of testing depends on the type of performance and metrics to be tested. Here are some common methods that may be used to test the performance of water-based inks:

Is the VOC emission of water-based ink high?

At present, developed countries and regions are trying to develop and use water-based inks to gradually replace solvent-based inks. Packaging printing with water-based ink printing as the main development object has formed a trend in the world. However, in China, the application of water-based ink is not very popular, and there is still a considerable gap compared with developed countries. Is the VOC emission of water-based ink high?

What is the difference between water-based UV ink and ordinary UV ink?

The biggest difference between water-based UV ink and ordinary UV ink is that water is used as a solvent, instead of using monomer diluent, which fundamentally solves the irritating effect of contact with the human body when using monomer diluent, and even calcium causes skin allergies and other harm to the human body, which has a greater advantage in environmental protection. What is the difference between water-based UV ink and ordinary UV ink?

How to avoid printing disputes between designers and printers (customers)?

Printing disputes are the most reluctant, but also the most frequently encountered problems in the process of communication between printing companies and customers. One of the reasons for the emergence of printing disputes may be that the printing quality of the finished product of the printing factory is unqualified, and there is another important reason, that is, the objective existence of printing errors. For professionals engaged in printing for a long time, some printing errors are objective and impossible to avoid; For customers who receive printed matter and play a decisive role in the acceptance of finished products, these errors are sometimes not fully understood. In this way, in the process of handing over finished products to customers, it is often the printing factory that thinks that its products are qualified, while customers insist that the products are unqualified or even unacceptable. As a result, after the dispute, the communication between the two sides is very difficult, the customer thinks that the printing plant is unqualified, but looking for excuses and unreasonable sophistry; The printing plant thinks that the customer is unreasonable and the payment credit is problematic.

The difference between RGB and CMYK

RGB color mode is a color standard in the industry, through the change of red (R), green (G), blue (B) three color channels and their superposition to get a variety of colors, RGB is the color representing red, green, blue three channels, this standard includes almost all the colors that human vision can perceive. It is one of the most widely used color systems. What is relevant to our computers is that most current monitors use the RGB color standard, which is why it is so important to us.

The advantages and disadvantages of composite printing

Composite printing, also known as Mosaic printing, is the combination of many different customers with the same print volume into a full-open large plate, forming batch and scale advantages, and jointly shared to save plate making and printing costs, generally about 30% lower than independent open plate printing. The advantage is that the unit price is low, a small amount can be made, and the delivery speed is fast.
