Single layer heat transfer inks whiteness and hiding power influencing factors

The whiteness and hiding power of single-layer sublimation inks are affected by many factors, the following are some of the main factors:

Type and content of pigment: The type and content of pigment are the key factors affecting the whiteness and hiding power of ink. Generally speaking, high-quality whiteness and hiding power require the use of high concentrations of good pigments, such as white pigments such as titanium dioxide and zinc oxide.

Selection and proportion of solvent: The solvent in the ink also affects the whiteness and hiding power of the ink. Some suitable solvents, such as toluene, xylene and other organic solvents, can better disperse and dissolve the pigment, and improve the whiteness and hiding power of the ink. However, excessive use of solvents will cause ink dilution and affect the hiding power of the ink.

Ink formulation and preparation process: The ink formulation and preparation process also have an important impact on the whiteness and hiding power of the ink. Reasonable formula and fine preparation process can ensure the uniform mixing of the components in the ink, and improve the uniformity and stability of the ink.

Properties of printing materials: The properties of printing materials will also affect the whiteness and hiding power of the ink. For example, different substrates, surface treatment methods and other factors will affect the ink's permeability, adhesion, and curing properties, thereby affecting the whiteness and hiding power of the ink.

Control of printing process parameters: The control of printing process parameters is also very important to the whiteness and hiding power of the ink. For example, parameters such as printing speed, pressure, and temperature will affect the transfer and curing of the ink, thereby affecting the whiteness and hiding power of the ink.

The above factors are not all, but they are some of the main factors affecting the whiteness and hiding power of single-layer sublimation ink.
