dtf film can be printed not only on tough crystal, stone, metal, glass and other materials, but also on soft leather, cloth, cotton and other materials. It can be printed on inorganic substances, and it can also be printed on organic compounds with complex compositions and changes.

Three technical parameters should be paid attention to in the use of dtf film:

1. Determination of speed:

1, should be based on the hot stamping area to a certain, together to think about the heating temperature power. Usually the primary speed, then some pressure, and eventually some temperature.

2. Determination of pressure:

2, hot stamping pressure is usually 4-6 kg/cm2. When the pressure is too small, the hot stamping film cannot adhere to the substrate, reducing the fastness; If the pressure is too large, the contraction deformation of the substrate will increase, forming a speckle deformation, and the printing layer will become thinner. It is assumed that when stamping chaotic and uneven products, we should pay attention to the average difference between the various pressure points, and the pressure viewpoint of the hot stamping wheel and the substrate is higher, otherwise, it is very simple to show some firm and some weak appearances.

Third, the determination of temperature:

3, when the temperature is too low, it will not be hot or hot, and it will make the impression flower; If the temperature is too high, the surface of the color layer will be oxidized, the product will lose luster, the color will be dark, and the severe will bubble. To determine the best hot stamping temperature should consider the following elements: pressure, speed, area, room temperature, etc.

dtf film refers to a special functional printing film with adhesive, which is separated from the carrier film together with the release layer under the combined action of heat and pressure and firmly transferred to the surface of the substrate.
