2025 New Guide -How to choose the high quality sublimation ink

High quality sublimation ink is mostly made of disperse dyes for textiles, other chemical additives and water. Disperse dyes are widely used in textile printing and dyeing due to their saturated colors and good weather resistance, and are still one of the main raw materials in the printing and dyeing industry. The traditional textile printing and dyeing industry has serious environmental pollution problems in the process of using disperse pigments for dyeing, and is not suitable for small-batch production. The emergence of thermal sublimation ink has made up for this defect.

How to identify whether a thermal sublimation ink is good or not?

We can confirm it from the following four dimensions.

1. The fineness of the printed pattern, the nozzle below 5PL is suitable for high-precision requirements, the high precision of the printer is very important, and the ink will also affect it.
2. Color consistency, it is related to the nozzle, ink, RIP software and machine brand.
3. Continuous productivity, it is related to the fluency of the ink and the fluency of the machine.
4. The physical and chemical testing indicators of the fabric, sunlight, dry/wet friction fastness, sweat fastness, as well as azo, heavy metal content and other indicators are related to the coating of ink and paper

The quality of dye sublimation ink is influenced by various factors.  Which can have a significant impact on the final print result. Here are some key factors that affect the quality of sublimation ink:

1. Ink Composition and Formulation

Pigment Quality: The type and quality of pigments used in the ink formulation play a crucial role in the vibrancy and accuracy of colors.

Chemical Stability: The stability of the ink’s chemical composition affects its performance during the sublimation process. Influencing aspects like drying time and heat sensitivity.

2. Storage Conditions

Temperature: Exposure to extreme temperatures (either too hot or too cold) can degrade sublimation ink, affecting its quality and performance.

Humidity: High humidity levels can negatively impact the ink by causing clumping or separation. While very low humidity can lead to evaporation and thickening of the ink.

3. Environmental Factors

Contamination: Dust, dirt, and other contaminants can affect the purity of the ink, leading to issues like print head clogging and reduced print quality.

Light Exposure: Prolonged exposure to direct sunlight or strong artificial light can cause sublimation ink to degrade or change color.

The quality of thermal sublimation ink is influenced by multiple factors, by selecting high-quality ink, maintaining optimal storage and handling practices, and using compatible printer settings and substrates, you can achieve vibrant, long-lasting prints with excellent detail and color accuracy.
