Offset thermal transfer printing ink

Types of offset thermal transfer printing ink

Offset thermal transfer printing ink is one of the most popular inks for printer manufacturers today. Using this ink with the offset printer produces sharper image prints than most other inks available.

When printing using an offset thermal transfer printer, the ink is first transferred to a thermal transfer plate. Then using heat, the ink is transferred to the printed material. The process of using heat to transfer the ink ensures that the ink creates clear and precise printed patterns. Hence, it is widely used in making printed patterns with fine details and multiple tones.

Offset thermal transfer printing ink can be majorly classified into the following types:

• Water-Based Inks

  This ink consists of a mixture of resins, pigments, and solvent water, which makes it easy to use. The printing industry prefers this ink because it does not affect the environment like other inks, which contain harmful solvents. Offset thermal transfer printing ink is best for printing on materials such as paper, cardboard, plastic film, and other non-absorbent materials. It bonds well with these materials and produces sharp printed patterns.

• Solvent-Based Inks

  Solvent-based inks consist of pigments suspended in a solvent base. Since solvents evaporate after being printed, the pigments remain on the surface of the printed material. This creates glossy patterns on the material. The strong adhesion of offset thermal transfer printing inks makes them ideal for use in packaging materials, glossy paper, plastics, and many non-absorbent surfaces.

• UV-Curable Inks

  UV inks are cured by UV light during printing to form a hard and durable surface. These inks are preferred for their quick drying time and ability to adhere to many surfaces, including materials that are difficult to print on. The offset thermal transfer printing ink is ideal for producing high-quality images and fine details and is used on labels, plastics, and metal surfaces. Its resilience and scratch resistance, all thanks to UV curing, make it a perfect ink for surfaces that may experience frequent handling.

• Plastic Inks

  Offset thermal transfer printing inks work well on plastics, including polypropylene, polyester, and PVC. Offset thermal transfer printing inks work well on plastic surfaces because they have a strong adhesion and produce a sharp image. Other than that, many of these inks are formulated to be flexible so that even after the printing process, they would not crack or peel off. This makes offset thermal transfer printing inks a go-to ink for printing on plastic labels, cards, and packaging.

• Metallic and Special Effect Inks

  Offset thermal transfer printing inks can be made with metallic particles or special effects like embossing. Those particles provide an eye-catching finish to printed materials, whereas special effects inks add texture and depth to the prints. Most these inks are used on greeting cards, labels, and other materials where high aesthetic value is important. With metallic finishes, standard materials can be turned into premium materials.

Designs of offset thermal transfer printing ink

Offset thermal transfer printing uses heat to transfer ink from a printing plate to a substrate. The process can produce prints with finer and sharper details and vibrant colors. The inks used in this form of printing are specially designed to ensure the best print quality on various surfaces.

The ideal offset thermal transfer printing ink formulations are selected based on the material to be printed, the requirements of the print quality, and the environmental standards the company must meet. The choice of ink assures precise color reproduction and strong adherence to multiple surfaces, from paper and plastic to metal and fabric.

Some of the important factors to consider when choosing printing ink are listed below:

• Viscosity

  Viscosity simply refers to the thickness level of the ink. Good offset thermal transfer printing inks should have optimum viscosity so they can easily flow through the thermal transfer printing plate and adhere well to the printed material. Low viscosity inks tend to produce blurred prints, while high viscosity inks affect the transfer process altogether. Thus, printers ensure that they use the right viscosity ink to achieve the right print quality.

• Color and Pigment Concentration

  The color or pigment concentration in the ink determines how vibrant the printed pattern will be. Offset thermal transfer printing inks come in various colors, including CMYK and Pantone colors. This color range allows flexibility in achieving the right printed pattern for the material. Those inks have high pigment concentration, which gives them the ability to print sharp and vibrant colors on various materials.

• Environmental Resistance

  The environmental resistance of the ink defines how it can survive exposure to moisture, heat, and chemicals. Most offset thermal transfer inks have high resistance to such elements, which improves their application in packaging and outdoor labels. Other formulations have UV inhibitors to prevent the colors from fading due to harsh sunlight exposure.

• adhesion and flexibility

  Adhesion refers to ink's ability to bind to different printed materials, while flexibility allows the ink to adapt to material surfaces without cracking or peeling off. Depending on the material they will be printed on, some offset thermal transfer printing inks have formulations that improve their flexibility and adhesion. This property makes them especially suitable for curved or textured surfaces, where the likelihood of ink peeling is high.

• Eco-Friendly Inks

  Ink containing low VOCs (volatile organic compounds) is becoming increasingly popular due to their eco-friendly properties. These inks do not contain VOCs or hazardous air pollutants in their formulations, so they do not negatively impact the environment.
