Heat sublimation transfer paper -Can we overcome its warpage by current technology?

Heat sublimation transfer paper is a kind of coated paper. The inconsistency of the coating layer and the bottom paper in drying and high temperature will cause single-sided warpage. When the transfer paper is warped, the following inconveniences will be caused:

Heat Sublimation Transfer Paper

1. The printer is inconvenient to feed sublimation paper. (drying warping at normal temperature)
2. When printing in large quantities in a stack, it is inconvenient to organize due to warpage. (drying warping at normal temperature)
3. Before the thermal transfer, due to the warpage of the transfer paper, the transfer failure is caused by the misalignment with the fabric. (drying warping at normal temperature)
4. Under the thermal transfer ironing board, the warpage of the transfer paper will cause the transfer to be misplaced and the transfer failure. (high temperature warping)
5.The width of paper may, in some point, have a connection with the curling of paper after the printing process, but technically speaking, it affects a little in the real operations.
6.Generally speaking, the thinner the paper, the easier the paper might be curled, and that is why most American users would choose to use low-weight sublimation papers. But thinner paper, like 45gsm, 60gsm can also perform very well with some famous printers, like Epson,Mimaki etc. This depends in deed.
At present, the products produced by various transfer paper mills at home and abroad have different degrees of warpage. The good quality transfer paper has a small warpage angle and slow warping, which can meet the flatness needs and time needs of the printing transfer production process. It is better to operate.

Sublimation Paper

Overcoming warpage is a difficult problem that sublimation transfer paper manufacturers have worked together to overcome. The double-coated method can effectively improve the warpage, but this increases the production cost, and most transfer paper production equipment often does not have such conditions. It can only be improved from the coating formulation and production process.

Water-based sublimation ink and oil ink, How to distinguish them?

The Water-based  ink includes sublimation ink and eco-solvent ink, and the oil ink includes pigment ink, the former ink needs to be transferred to the object by a medium, and the latter ink can be directly sprayed on the fabric to be printed. Do you know how to distinguish the difference between the two?

Water-based Sublimation Ink

Water-based sublimation ink, also known as water-based thermal transfer ink, is a low-energy, easily sublimated disperse dye made into digital printing ink, and then printed on transfer paper. By heating, an image can be produced in the shortest amount of time. Exquisite porcelain, metal, silk, chemical fiber fabrics and other materials. It is ideally suited to the market needs and environmental requirements of individual development.
Since the aqueous sublimation ink is an aqueous ink, it is mainly produced by a composite grinding process from a water-based resin, an organic pigment, a solvent, and related additives. Water-based inks are especially suitable for packaging and printing products with strict hygienic conditions, such as tobacco, wine, food, beverages, pharmaceuticals, children's toys, etc.
The main difference between aqueous inks and oily inks is the different solvents, one being water as a solvent and the other being an organic solvent as a solvent.

The difference between the two inks is as follows:

1. Water-based ink is prepared from water-based resin, soluble in water and diluted with water. The advantage of water-based ink is that it does not require organic solvents, reduces solvent evaporation, prevents air pollution, does not affect human health, and is not easy to burn. It is an environmentally friendly ink. Oil-based inks and solvent-based inks are insoluble in water and soluble in organic solvents, but these organic solvents react with certain substances in the air to cause pollution.
2. Water-based sublimation transfer ink, stability and can make the color bright. The price is cheap, the adhesion after printing is good, the drying is fast, and the water resistance is strong. Oil inks are characterized by high ink viscosity, fast drying, water resistance, softness and light fastness. When used, ink is more economical and saves costs.

 Sublimation Printing Ink

3. Water-based inks are commonly used in food, medicine, beverage and other industries, and the packaging and printing industry is also widely used. Oil-based inks are mainly used in metals, plastics, wood, aluminum foil, carton and building materials.
4. Oil-based inks can be diluted with organic solvents and printed on absorbent and non-absorbent surfaces. It is not easy to fade after printing. Aqueous inks cannot be diluted with organic solvents.
