How to make color-changing ink

As a unique ink type, color-changing ink has attracted much attention because of its magical color-changing effect. This article will deeply discuss the production methods and application fields of color-changing ink, and reveal the magic color-changing technology of ink industry for readers.

First, the production method of color-changing ink

1. Pigment selection:

The core of color-changing ink is a special pigment, whose color-changing effect depends on the chemical composition and structure of the pigment. Common color-changing pigments include heat-sensitive pigments, light-sensitive pigments, chemical reaction pigments and so on. Depending on the needs of different applications, choosing the right pigment is crucial.

2. Ink formula design:

Ink formulation design is a key step in making color-changing ink. In the formulation design, it is necessary to consider the stability of the pigment, color change effect, printing performance and other factors. Through the reasonable allocation of different components of the ink, can achieve different color-changing effects.

3. Process control:

The production of color-changing ink requires strict process control. In the production process, it is necessary to control the key parameters such as the particle size, dispersion and stability of the pigment to ensure the quality and discoloration effect of the ink. At the same time, it is also necessary to control the viscosity, fluidity and other physical properties of the ink to adapt to different printing equipment and printing materials.
