In traditional inkjet printing, due to the poor dispersibility of pigments, ink droplets tend to spread unevenly and penetrate irregularly once they are ejected onto the substrate, resulting in blurred image edges and loss of fine details. However, inks treated by a coating-modification machine exhibit uniformly dispersed pigment particles, with more stable droplet shapes and sizes, enabling precise placement on the substrate. In high-resolution textile printing, inks processed by the coating-modification machine can vividly reproduce intricate pattern details—such as delicate floral textures and subtle facial expressions—making the printed designs appear lifelike and imbued with exceptional artistic value. Moreover, thanks to the improved pigment dispersibility, the color saturation and vibrancy are significantly enhanced, giving printed products richer, more dazzling colors that effortlessly capture consumers' attention. 。

Pigments treated with a coating modification machine exhibit stronger adhesion to the substrate material. This is because the coating not only improves the surface properties of the pigment but also interacts with the molecules on the substrate’s surface, forming chemical bonds or strong physical adsorption. Even after multiple washes and rubs, the printed patterns can still maintain their vibrant color and integrity, resisting fading and peeling.

The phenomenon of bleeding is a common issue in inkjet printing, leading to distortion of printed patterns and color mixing. Coating modification machines can effectively reduce the occurrence of bleeding. By subjecting the ink to coating modification, the surface tension and viscosity of the ink are adjusted, enabling ink droplets to adhere rapidly to the substrate and minimizing their diffusion on the material's surface. In paper printing, ink treated with a coating modification machine can precisely control the position of ink droplets during high-speed printing, preventing excessive penetration of ink between paper fibers. As a result, the edges of the printed patterns become crisp and sharp, color boundaries remain distinct, and the quality and premium appeal of the printed products are significantly enhanced. 。
