What is the difference between thermal transfer printing and sublimation printing
Oct 09, 2022
Thermal transfer printing generally has the following two types:
1. Sublimation printing (also called sublimation heat transfer printing).
2. Heat transfer printing.
Sublimation printing can be divided into:
1. Offset sublimation printing. Use an offset press to print the sublimation ink on paper with a thickness of about 80 g/㎡, and then do sublimation heat transfer printing on the chemical fiber fabric after drying.
2. Silk screen sublimation printing. Use a screen printing machine to print the sublimation ink on paper with a thickness of about 80 g/㎡, and do sublimation heat transfer printing on the chemical fiber fabric after drying.
3. Gravure sublimation printing. Use a gravure printing machine to print the sublimation ink on paper with a thickness of about 30 g/㎡, and do sublimation heat transfer printing on the chemical fiber fabric after drying.
4. Digital thermal transfer printing (same as: digital sublimation printing). Using a digital printer connected to a computer, the processed patterns are pre-printed on a specific coated paper with sublimation ink, and then sublimation heat transfer printing is done on the chemical fiber fabric after drying.
The above types of sublimation printing are suitable for fabrics: chemical fiber, the most ideal fabrics: pure polyester. Sublimation transfer temperature: above 200℃. Fabric color: white or light. Post-press effect: The sublimation ink penetrates the fiber, so the hand feels softer.
Thermal transfer heat transfer can be divided into:
1. Offset heat transfer. The effect of offset printing is made by superimposing four colors, and the pattern is clear and realistic, which can achieve the effect of photos.
2. Spot color heat transfer. The printing area is solid, unlike superimposed offset heat transfer dots, and the color is relatively pure.
In addition, reflective heat transfer, bead heat transfer, gold and silver onion heat transfer, etc. belong to the category of heat transfer heat transfer, but the materials used are slightly different, but they have one thing in common: hot melt glue (powder) will be used to transfer heat transfer. The pattern sticks to the fabric firmly. So when you touch it with your hands, it will have a gelatinous feel.
The effect of reflective heat transfer is that it will reflect light against the light, and the gold, silver and onion heat transfer will look like there is a metal-like substance after being ironed, giving people a noble and gorgeous feeling! There are beads on the surface of bead heat transfer, and the gorgeous colors at the bottom are refracted by the beads, which also gives people a noble and gorgeous feeling!
