Against the backdrop of booming personalized customization and digital printing industries, thermal sublimation ink, as a core consumable, directly determines the visual impact and service life of final products. So how can we identify high-quality thermal sublimation ink through its key performance indicators?
Key Indicator 1: Color Fastness
Poor-quality inks with insufficient color fastness may fade or experience layer peeling after just 3 washes, leading to return rates as high as 30% and severely damaging brand reputation.
OBOOC Thermal Sublimation Ink has passed color fastness testing with a wash fastness rating of ≥4, and supports durability verification across multiple materials. Its light fastness reaches 4.5, and its migration fastness exceeds level 4. Even after 50 machine washes, it maintains over 90% color saturation.

Key Indicator 2: Color Reproduction Rate
Inferior inks often exhibit purplish-red casts in black areas and grayish-white haze in colored patterns due to low dye purity, achieving less than 70% actual color reproduction. A simple test involves printing solid black samples: premium inks transfer to true charcoal black, while inferior products show reddish or purple tints.
OBOOC Thermal Sublimation Ink employs a 6-color system (including light cyan/light magenta) with 0.3-micron dye particles to achieve over 90% color reproduction. After transfer, the paper appears nearly white, delivering print-like richness with layered detail.
OBOOC Thermal Sublimation Ink achieves over 90% color reproduction accuracy.
Key Indicator 3: Particle Fineness
Coarse ink particles (>0.5 microns) not only cause nozzle clogging and printing streaks, but also create visible graininess in images.
OBOOC Thermal Sublimation Ink features particles ≤0.2 microns, making it fully compatible with precision printheads like XP600 and i3200. It enables 100-meter continuous printing without breaks, doubles nozzle lifespan, and improves image resolution by 40% - particularly suitable for high-end apparel and artistic frames requiring fine detail reproduction.
OBOOC Thermal Sublimation Ink features exceptionally fine particle size.
Key Indicator 4: Fluidity and Adhesion
Ink with poor fluidity tends to cause misting and feathering, leading to over 10% material waste; inadequate adhesion results in blurred or peeling layers.
OBOOC Thermal Sublimation Ink regulates surface tension and evaporation rate to achieve rapid color fixation within 0.5 seconds during high-temperature transfer. Utilizing nano-penetration technology, it forms a dense molecular film on polyester fiber surfaces, ensuring vibrant color reproduction while enhancing scratch resistance by 300%.
OBOOC Thermal Sublimation Ink ensures smooth and consistent inkjet performance.
