Blurring in textile thermal sublimation printing: personal suggestions and solutions
How to deal with the blur and secondary dye in textile inkjet printing?
The question of blur has been a problem that plagues dispersed ink printing. This will not only affect the pattern of the product but also damage your brand phenomenon and leave a bad impression on others.
What causes blur in dispersed printing?
The fabric is too absorbent: If the fabric is highly absorbent, the ink will be quickly absorbed and diffused as soon as it contacts the fabric, resulting in blurred edges of the pattern.
Poor compatibility with ink and fabric: The chemical properties of the dispersed ink do not match the fiber type of the fabric, which may cause the ink not to be well fixed on the fabric, causing blurring.be well fixed on the fabric, causing blurring.
The ink fluidity is too high: If the viscosity and fluidity of the ink are too high, it is easy to diffuse on the fabric's surface, causing blurring.
The printing nozzle is clogged: The pressure of the nozzle is too high, causing the ink to drip too fast.
Drying problem: If the ink dries too slowly, this will cause excessive diffusion of the ink on the textile, thereby contaminating the textile.
Improper distance between the print head and the fabric: If the distance between the print head and the fabric is too close or too far, it may affect the jetting effect of the ink droplets and cause ink halting.
Printing speed: Printing too fast may cause the ink to not dry in time, while printing too slow may cause the ink to accumulate on the fabric, which may cause ink haloing.
Matching of ink and substrate: Dispersed ink is prone to ink haloing on natural fibers.
How should I deal with the dispersed ink blur phenomenon?
Adjust the corresponding ink formula and change the type of ink
Select the ink type and formula suitable for specific fabrics.
Adjust the viscosity and fluidity of the ink to adapt to the characteristics of the fabric.
Optimize printing parameters such as inkjet pressure, printing speed, and drying temperature.
Control the temperature and humidity of the printing environment to facilitate the rapid drying of the ink.
Regularly maintain the printing equipment to ensure the cleanliness and precise alignment of the print head. tot
