1) Influence of temperature on bronzing quality: the temperature is appropriate.
thermoprint
It has a very important influence, and the temperature must be controlled within the corresponding range, so that the dyeing resin layer and adhesive can be melted moderately and the aluminum layer can be transferred well. If the temperature is too high, excessive melting, hot stamping around the text.
anodised aluminium
It also melts and falls off.
Paste board
At the same time, high temperature will cause chemical changes in anodized dyeing resin and aluminum layer, and the brightness of hot stamping products will be reduced and lost.
metallic lustre
Even make the imprint appear blurred or blistered; However, if the temperature is too low and the melting is not sufficient, it will also cause the hot stamping not to go up or not to be firm, the mark will fall off easily if it is not firm, or the mark will be dizzy if it is scratched due to lack of pen.
2) Influence of pressure on hot stamping quality: The hot stamping transfer of aluminum layer must be completed by pressure, and the hot stamping pressure affects the adhesion fastness of anodized aluminum. Even if the temperature is right, if the pressure is insufficient, anodized can't be transferred to.
stock
In fact, there will be problems such as weak imprint and flower version; On the contrary, if the pressure is too high and the compression deformation between the liner and the substrate is too large, the imprint will be rough, even adhered and pasted. Usually, the hot stamping pressure should be adjusted appropriately to achieve no
Boring
Good adhesion fastness is the standard.
To adjust the hot stamping pressure, many factors such as substrate, hot stamping temperature, vehicle speed and anodized itself need to be integrated. Generally speaking, when the paper is firm and smooth, the printing ink layer is thick, the hot stamping temperature is high and the vehicle speed is slow, the hot stamping pressure should be small, otherwise it should be large. Hot stamping pressure must be uniform. If it is found that the local hot stamping is not smooth, it is likely that the pressure here is too small. The flat here should be padded with a layer of tissue paper to balance the pressure.
3) The influence of speed on the quality of hot stamping: The speed of hot stamping actually reflects the contact time between the substrate and the hot stamping foil during hot stamping, which directly affects the fastness of hot stamping. Hot stamping speed is too fast, which will lead to hot stamping failure or imprinting; Too slow hot stamping speed will not only affect the quality of hot stamping, but also affect the production efficiency. In addition, the factors that limit the speed of hot stamping are the model and performance of anodized itself. Different models and performance have a great influence on hot stamping speed.
