WHY POLYESTER WORKS SO WELL IN DYE SUBLIMATION PRINTING?

dye sublimation printingDye sublimation is an advanced printing method that involves transferring text or graphic images onto items. When it comes to picking a fabric for dye sublimation printing, polyester is the best choice. Here is why polyester works so well in dye sublimation printing:

1. Beautiful, lasting printed colors
Dye sublimation printing consists of the following steps:
1) A graphic or text is digitally printed on sublimation transfer paper.
2) The transfer paper is placed in a heat press. The heat press helps sublimate the print onto a fabric.

It’s important to test fabrics before dye sublimation printing. Due to high heat, with temperatures ranging from 380 to 400 degrees, a fabric may easily burn. Heat is used to convert the dye sublimation ink into a gaseous state.

Fabrics such as cotton, nylon, etc. cannot hold the ink during the heating process.  Polyester is the only material that can enable the bonding of the ink and ensure beautiful, long lasting colors. This is why national flags, banners and graphic t-shirts are made of polyester.

2. Fade-resistant
Printed graphics, text or logo on polyester fabric will not crack, fade or diminish. No matter how many times you wash it, the printed image won’t come off or lose color.

On the other hand, printed images on a cotton fabric can chip or peel off. Cotton is prone to fading, especially after repeated washing.

If you are looking for permanent printing then polyester is the best one. Printed images are embedded in the fabric’s substrate rather than printed on the surface.

3. Rich printed colors
Last but not least, polyester ensures rich printed colors. As sublimation dye is converted to gas during heating, the fabric’s tone blend into each other. The final product looks absolutely stunning.

4. Percentage of polyester in a fabric
It’s a good idea to use a 100 percent polyester fabric to achieve the best result. But, you can even work with at least 60 percent polyester fabric.

What’s the Influence of Humidity on Sublimation Transfer Papers?

sublimation transfer paperDo you know why the instruction manual that comes with sublimation transfer papers also specifies the humidity levels it should be stored at? Specifying humidity levels for paper storage hardly makes any sense, other than giving an impression that you must be using a high-end product. But the matter of fact is there’s indeed a link between the performance of a transfer paper and the humidity levels it is exposed to (stored at).

1. What humidity does to a transfer paper?

A sublimation transfer paper can absorb and retain an enormous amount of moisture. It’s like a sponge. The problem is that if it absorbs moisture in excess, at the time of printing, the trapped moisture in the transfer paper can flash to steam and blow away the ink from its target area. This can result in printing artifacts such as color shifting, uneven transfer and bleeding of the image.

sublimation paperTherefore, manufacturers specify optimum humidity levels for transfer paper storage so that the paper doesn’t absorb moisture in excess from its stored environment. Failure to comply with the instructions is likely to affect the performance of transfer paper at the time of sublimation printing.

2. What if a sublimation paper gets exposed to high humidity levels?

Before using the paper, set it on the press for a few seconds. Place it 2 to 3 inches below the heat plate. The heat from the pressing machine should help evaporate the absorbed moisture. If the image has already been transferred onto the paper, you can employ the same strategy to save the print, however, the final transfer may appear slightly faded or washed out.

How about the Printing Efficiency of Sublimation Transfer Paper

sublimation transfer paperThermochromic printing has long been applied to the printing process. Sublimation transfer paper has adopted similar processing methods and through this model to improve the processing printing methods. This is also a feature of modern printing plants.

Thermal discoloration can process dyes according to the changes of the environment and temperature. And it can more quickly adapt to the modern printing paper process. With this type of thermal sublimation, transfer paper naturally improves the efficiency of the printing process.

After the preliminary preparation of the printing paper, it can also be printed on the reversible and irreversible two types of finished products by sublimation transfer printing paper. The effect of products made in this way is also different. In order to ensure the force of the printing process, you can also add other additives as required. It can ensure the sublimation transfer effect and to ensure the final appearance of the processed printing product. These printings are extremely delicate. Any mistakes in any one of these links are irreversible. This requires us to strive for excellence in the printing process and ensure that each link is accurate. With this intelligent sublimation transfer printing machine, the speed and quality of printing can be guaranteed.

In the printing process, each thermochromic pigment is subject to the intelligent

instructions of the machine. This kind of printing process will be more stable and accurate. Sublimation transfer paper, as a professional paper printing material, can provide stable temperature detection instructions for processing and printing plants. It can also help smart printing and provide stable and reliable processing efficiency. Such materials are certainly very good when they are popularized, and they can help improve work efficiency. This kind of material must pay attention to use in conjunction with their use.

Our company offers the equipment in sublimation printing process, such as sublimation paper, sublimation ink, inkjet printer and some other accessories. If you have any demand, please feel free to contact us.
