As the name of fashion and personality printing technology, digital thermal transfer printing has undoubtedly received a lot of attention and favor, and its "blood" ink has become the fastest and most exchanged consumables. Knowing more about ink is of great significance for us to print better images.
1. The composition of ink
Ink is usually composed of solvents, colorants, surfactants, PH regulators, driers and other necessary additives. Among them, the solvent accounts for the largest proportion in inkjet printer ink and is the main component. The performance of the colorant directly affects the color and tone of the printed image, and its own color, mixing performance, solubility, acidity and alkalinity, and particle size are particularly important.
Second, the main performance parameters of the ink
Ink for inkjet printers requires high thermal and chemical stability. The performance parameters that affect the printing effect of ink mainly include the following:
1. Viscosity and surface tension: Viscosity is the resistance of liquid flow, and the surface tension of liquid is related to whether droplets can be formed. Generally speaking, inkjet ink must have a low viscosity and high surface tension to ensure good flow. Properties and droplet morphology.
2. PH value: It represents the concept of the pH value of the liquid. The more acidic the solution, the lower the pH value. On the contrary, the more alkaline the solution, the higher the pH value. In order to prevent the ink from corroding the print head, the pH value should generally be between 7-12.
3. Conductivity: In ink, the conductivity value is used to reflect the level of salt content. In general, the salt content should not exceed 0.5% to avoid clogging by crystal formation in the nozzle.
4. It is a dispersant: a kind of surfactant, its main function is to improve the physical properties of the ink surface and enhance the affinity and wettability of the ink and the sponge. Therefore, inks that are generally stored and conducted through sponges contain dispersants.
Choose the best quality materials, check the above parameters, Dongguan Minuo Phenomenon Digital Thermal Transfer Technology Co., Ltd. has launched the following two high-quality inks, each with its own characteristics, I believe it will be your first choice.
