1. Natural dye extraction method and DTP ink manufacturing process
Domestic wild natural dyestuffs are mainly used to exclude imported dyeing materials. The extraction method is semi-finished products produced by vacuum extraction from our own vacuum extractor and filtered to produce finished products.
Depending on the characteristics of the DTP machine and the injection method, some natural derivatives are used.
After extracting the natural dye, apply it to the printer of each model, and the method of production may be different.
1. Testing Machine Type: DIGEN 740
2. Flatbed printers: mc25
3. Spherical piezo method: DMXⅡ- 6000
4. Spherical spiral method: hhu1
To develop natural DTP inks and improve the technology to apply them.
2. Success of DTP printing with natural dyes
