In this issue, we delve into the world of heat transfer printing, specifically examining the differences in application between DTF ink and sublimation ink. These two methods, though similar in purpose, possess distinctive characteristics in terms of their ink types, color development processes, and media adaptability. 

DTF ink, commonly known as film transfer ink, utilizes pigment ink as its medium. This type of ink relies on a complex interplay between resin, adhesive, and the colored object to achieve a firm grip. In contrast, sublimation ink belongs to the family of dye-based inks, which possess a affinity for textile dyes and can be absorbed by fiber molecules. This attribute renders sublimation ink more stable in heat transfer printing.

The two ink types differ significantly in their color development processes. DTF ink requires 150°C for around 15 seconds to generate color, whereas sublimation ink needs 200°C for approximately 30 seconds. This disparity stems from the distinct nature of their colorants: DTF ink relies on pigments, while sublimation ink employs disperse dyes that require a temperature of 200°C to fully react.

When it comes to media adaptability, DTF ink boasts a broader range of applications compared to sublimation ink, especially on media that cannot withstand the high temperatures required for color development in the latter. The color generation process for sublimation ink transpires at 200°C, which may cause deformation or yellowing in certain materials or fabrics. In contrast, DTF ink requires only 150°C to achieve smooth color generation on numerous media.

Despite the current cost difference, with DTF ink being higher, both methods offer unique advantages and can coexist in various applications. DTF ink solves the issues of fastness, color, and feel in cotton digital printing and expands upon the pigment digital printing scheme. Our comprehensive solution for DTF printing incorporates printers, hot stamping ink, hot stamping film, and hot melt powder, ensuring outstanding cost-performance for your printing requirements.
