The difference between UV ink and thermal sublimation ink
Date: Sep 04 2024 From: Star Color
In the printing field,
UV ink and thermal sublimation ink as different types of ink, has a wide range of applications in the printing industry. UV ink with its fast curing, bright colors, environmental protection and energy saving features, in packaging printing, advertising production, electronic product manufacturing and other industries shine; while the thermal sublimation ink is rich in color, delicate patterns, inexpensive, in the field of textile printing and dyeing, personalization and so on. It occupies a place in the textile printing and dyeing, personalized customization and other fields.
Definition and basic principleUV Ink: As a special ink that cures quickly through ultraviolet radiation, UV ink shows great efficiency and flexibility in the printing process. The basic principle is that, when UV ink coated on the surface of the substrate, through a specific wavelength of ultraviolet radiation, the photoinitiator in the ink rapidly absorbs light energy and converts it into chemical energy, which triggers the polymerization of resin monomers to form a stable body structure, to achieve rapid curing of the ink. The whole process is less than 1/10 second.
Thermal sublimation ink: It is a special ink that utilizes thermal transfer technology to print patterns directly onto the substrate. Its working principle is that, in the printing process, the thermal sublimation ink is first printed on the special transfer paper, and then heated by high temperature so that the ink from the solid state directly sublimated into a gaseous state, and penetrate into the fiber gap in the chemical fiber fabrics, and the fabric is closely combined with the formation of a permanent pattern.
Performance characteristicsPerformance characteristics of UV ink:
Fast drying and curing fast: UV ink can be cured quickly under ultraviolet radiation, greatly improving production efficiency.
High quality: the cured ink film is brightly colored, glossy, wear-resistant, and has excellent resistance to light, water and chemical corrosion resistance.
Environmental protection: UV ink does not require solvent dilution, reducing VOC emissions, in line with environmental requirements.
Performance characteristics of thermal sublimation ink:
Colorful: Thermosublimation ink can present delicate and rich color layers to meet the needs of personalized customization.
Firmness: It combines firmly with chemical fiber fabrics and is not easy to peel off or fade, which is suitable for long-term preservation and wearing.
Softness: The printed fabrics are soft to the touch and do not affect the wearing comfort.
Application areasApplication areas of UV ink:
Printing industry: widely used in packaging printing, label printing, book printing and other fields.
Electronic products: used in printed circuit boards, touch screens and other electronic parts to ensure high precision and high stability.
Industrial manufacturing: used for spraying and marking in automobile manufacturing, home appliance manufacturing, and other fields.
Application areas of heat sublimation ink:
Textile printing and dyeing: mainly used for personalization and decoration of chemical fiber fabrics such as T-shirts, pillows and curtains.
Advertising industry: to make all kinds of displays and promotional items, such as flags and banners.
Personalized gifts: widely used in photo printing, cell phone case customization and other personalized gift production.
Precautions for usePrecautions for the use of UV ink:
Light source matching: Make sure that the emission spectrum of the UV lamp in the UV printer matches the absorption spectrum of the photoinitiator in the UV ink to get the best curing effect.
Temperature control: keep the room temperature moderate and constant, to avoid UV ink due to temperature fluctuations and performance changes.
Equipment Maintenance: Regularly check and maintain the UV printer to ensure that the printhead is unobstructed and to prevent the occurrence of blockage or ink leakage.
Precautions for the use of thermal sublimation ink:
Substrate Selection: Ensure the selection of suitable substrates for heat sublimation technology, such as chemical fiber fabrics, in order to obtain the best printing results.
Temperature control: Strictly control the temperature and time during the thermal transfer process to avoid overheating leading to fabric damage or uneven ink penetration.
Environmental requirements: Keep the working environment clean and ventilated to avoid dust and impurities affecting the print quality.
Overall, there are significant differences between UV ink and thermal sublimation ink, which can be said to be two completely different inks.UV ink with its high efficiency, environmental protection, high quality features in a number of industries play an important role;
While heat sublimation ink has occupied a place in the field of textile printing and dyeing and personalized customization with its advantages of rich colors, delicate patterns and perfect combination with chemical fiber fabrics.
