How do you know whether a photo is printed with dye ink or pigment ink?

1. Ordinary ink used by users is dye ink, and pigment ink is generally marked on the package.

2. Pigment ink is more expensive, and the price is n times that of dye ink.

3. From the appearance of ink, taking ink as an example, dye is transparent, while pigment ink is opaque.

4. When printing pictures, if the use cycle of the pictures is not long, dye ink has obvious advantages over pigment ink in color performance.

5. The problem that dye ink can't be waterproof can be solved by other methods, such as sticking a layer of transparent glue on the picture, or directly molding (the printing shop or printing shop usually has this service), or it can be waterproof and can be stored for a long time.

Precautions:

1, solvent-based pigment ink overcomes the photochemical activity of dyes, because pigments can be understood as the precipitation, fading and change of dyes or inert substances similar to sand, which can be stored outdoors for a long time.

2. Technology: Dye ink will fade quickly under outdoor light, and it is only suitable for indoor use, and it is not scratch-resistant and waterproof. Using solvent-based pigment ink can have weather resistance for three years, without laminating, which can save the troublesome processing procedures of gluing and laminating, and can realize short-time delivery.

3. Solvent-based pigments are used for direct printing, which can reduce the cost without laminating processing machinery and materials and printing materials with special coatings. ?

4. In terms of printing efficiency, in addition, the solvent-based printer adopts a new print head, which greatly improves the printer performance. Pigment ink is only used when painting outdoor products in China. Pigment ink can be used for internal and external users, which conforms to the trend of international advertising and painting. Moreover, the product itself is constantly improving, which stimulates domestic enterprises to study solvent-based pigment ink.
