In recent years, as technology is developing rapidly, printing has become diverse and
tends to mechanization. In these printings, DTG(direct to garment)is the most typical
example. The printing presented by this printing is colorful and high-precision pattern,
without plate making, and the pattern is basically unlimited. But DTG printing so good,
why not replace other printings?
In this blog we use dye-sublimation in thermal transfer printing as an example.
First of all, let's understand what thermal transfer is and what DTG is.
What is dye-sublimation
Use special thermal transfer ink to print on thermal sublimation paper or color ink-jet
paper, and transfer pigment molecules to the fabric by heating. Because only the ink is
transferred to the fabric, it feels good handle. Designs that can transfer pattern effects
and details.
What is DTG
DTG, which works like a printer, prints color images directly on clothes. Its main tools
include ink, clothes, and machines.
Now we get back to the main topic, why DTG couldn’t replace dye-sublimation?
- Fabric
Dye-sublimation mainly prints polyester fibers, and the effect of printing 100% polyester
fibers is very good, but if there is some cotton inside, white spots will be exposed.
Cotton fabric is suitable for DTG to do. But DTG is more suitable for printing light color
preferably white, the effect will be very good.
- Color
Dye-sublimation: Due to the heat transfer of pigment molecules onto the fabric, so the
colors are vivid and layered, able to design details to show the subtle differences between
adjaent colors without affecting the original texture of the fabric.
DTG: High-precision pattern, but unable to accurately match colors. The real patterns may
be darker than the manuscript. Of course, today`s ink equipment can already solve this
problem very well, but it also prompts the issue of cost.
- Cost
There is no doubt that DTG is more expensive than thermal transfer. Because the ink
required for DTG is more expensive, just like girls' liquid foundation.
But dye-sublimation, because of its need for engraving, the number of colors has
becomea very important part. Therefore, if mass production, dye-sublimation is suitable,
but if small batch, you can choose DTG.
In a word, both have their advantages and disadvantages. If you want to order the
cotton fabric, pattern more details of the T-shirt, you can choose DTG. If you want
customized jerseys, quick drying clothes, etc., you can choose dye-sublimation.
