White ink has always been an important player in pigment printing solutions. Despite the high price, customers still flock to it. However, the maturity of the white ink solution has always been the bottleneck of the entire coating solution market. Although many manufacturers supply white ink or white ink solutions, the quality is uneven and the price remains high. How to choose a reliable white ink?

 

1. Whiteness and hiding power
In the application of the DTF printing, the whiteness of white ink is determined by the concentration. The higher the solid content of white ink, the higher the whiteness of the film after transfer, and the stronger the hiding power.
In the application of DTG printing, different treatment liquids have a greater impact on the whiteness. Usually, ink suppliers will provide matching pretreatment liquid. The main problem is whether there are traces after the medium is sprayed with the treatment liquid, whether the hand feel is affected, and whether the white ink can completely cover the background color of the cloth and show sufficient whiteness.

 

 

2. Stability and no clogging
The stable performance of white ink has always been an important bottleneck in the application process. Due to the large proportion of titanium dioxide, the color material of white ink, it is easy to cause sedimentation, and the stability of the dispersion system has a high technical content. In order to better solve the problem of white ink stability, equipment manufacturers usually circulate or keep the white ink in a stirring state.
At present, the white ink on the market has a precipitation phenomenon, which will more or less delaminate after being placed for a period of time. The criterion for judging is whether it can return to a stable state after shaking. At the same time, it can print smoothly, without clogging the nozzle, and meet the application performance. After the white ink with poor stability is shaken, the printing will still not be smooth, and it is prone to breakage and plugging.

 

 

3. Hand feeling
Hand feel is a key evaluation index for white ink application, and soft hand feel is the requirement of customers. The feel of white ink is mainly related to the raw materials selected for the production of white ink. Good white ink will be prepared from higher quality raw materials and will be softer. In addition, the white ink treatment solution of DTG also has a great influence on the feel of white ink.

 

4. Compatibility with color ink
White ink usually needs to be used together with color ink. The compatibility of white ink and color ink is very important for the application of white ink, otherwise, neither DTG printing nor DTF printing can obtain the best ideal effect. If the white ink and color ink are not compatible, the printed pattern will appear smudged, scattered ink, etc.

 

 

5. Colorfastness
Colorfastness has always been the focus of customers' attention. The color fastness of the white ink solutions on the market is also uneven. The white ink fastness is related to the treatment liquid, white ink, and different fabric media. It is necessary to comprehensively evaluate whether it can meet the application requirements. It is best to choose a supplier who can provide a complete package. Professionals can better understand the whole program.
