A good product of hydrographic transfer printing hot stamping foil has a lot of aspects to pay attention to, because the whole product will be affected by every small detail. So what skills are worth of referencing?
PRESSURE. Strong pressure will lead to paste version or imprinting coarsens, when pressure is too small, hydrographic transfer printing hot stamping foils are unable to adhere to products, and are unable to cut the area of the hydrographic transfer printing.
Speed. It actually reflects the contact time among hydrographic transfer printing hot stamping foil materials and substrates, which directly affect the fastness of hydrographic transfer hot stamping foils. When the speed is too fast, it will be difficult to hot stamp or the print pictures will be fuzzy. Slow speed will affect both the quality and the production speed.
In general case, we will not change speed. That is to say, the speed is constant, when the condition changes, we usually adapt to the conditions by changing the temperature and pressure.
Features: coating. Its surface coating is equivalent to print a layer of metal color in advance. It has smooth surface, poor permeability, and bad adhesion performance of oils. It is best to use synthetic paper for ink printing, the ink volume should be smaller, and spray powder should not be too much, and we’d better to do thin printing. When imprinting is completely dry, then we can use hydrographic transfer print hot stamping foils. Another way is to print a thin layer of the base, where the foils are needed.
In addition, we often use good assistant when we do hydrographic transfer print hot stamping: adhesion material. We often use it because the hydrographic transfer print hot stamping foil itself has no adhesive ability. Using adhesion material can make hydrographic transfer print hot stamping foils adhere to the products even without enough adhesive capacity, by heating the hot pressed and glued firmly bonded together, so form a good effect of hot stamping. This kind of adhesion materials can be divided into two categories:
Sticky material liquid mainly includes shellac and protein fluid.
In reality, hydrographic transfer print hot stamping foil adhesion materials must be used when we do metal hot stamping, because this type of the hydrographic transfer print hot stamping foil itself has no adhesive ability, or the ability is poor. When it is difficult to hot stamping and the other conditions are normal, we also can use the adhesion material, then we can secure the hydrographic transfer print hot stamping foils..
Glue powder mainly has pine powder, protein powder and iron powders.
The hydrographic transfer print hot stamping foils will be better when we costing little these kinds of powders on the surface. The disadvantage is that they cannot be adhered on the surface which is too smooth.
