It is also important to choose the correct foil material based on the specific conditions of the substrate. The coated and uncoated substrates have different requirements for hot stamping foils, and some hot stamping foils are specially made for substrates with surface coatings or surface printing layers. Some hot stamping foils are specially used for hot stamping of other texture substrates.
Some substrates require hot foil after printing, and some substrates require hot foil printing. Regardless of the pre-press foil or the post-press foil, it must be ensured that the surface of the foil to be foiled must not contain any type of wax or oil traces and requires a pressure of 38 dyne or higher. Before the foil is stamped, the coating on the surface of the substrate and the printing ink must be completely dry before the foil is stamped. In addition, there are many types of surface coatings or inks on the substrate. When performing foil stamping on a specific coating or a specific printing ink, you must choose a matching hot stamping foil material, if necessary, according to the coating. The characteristics of the layer or printing ink, specially formulated to customize the corresponding hot stamping foil, the only way to ensure the quality of foil hot stamping. For this reason, it is recommended to discuss and unify the best matching scheme between the three suppliers before the implementation of foil hot stamping, so as to avoid the mismatch of material properties. And the quality problems that arise.
When properly selecting the appropriate hot stamping foil material, the hot stamping process and the design of the carton are two factors that should be considered and important. If a large area of hot stamping is implemented, a hot stamping foil material that is easier to peel off may be used; if the hot stamping area is small, the hot stamping image is thin and thin, such as hot stamping text or lines, it is necessary to use texture. A hot stamping foil that is solid and not easily peeled off.
When selecting a hot stamping foil, the flat stamping is different from the foil used for rotary stamping. The formulation and production of hot stamping foils are strictly targeted. Depending on the hot stamping process and the processing method, the foil materials used are strictly different. In addition, in the hot stamping process, it is important to accurately calculate and determine the correct time to maintain the maximum thermal pressure. Different hot stamping processes and processing methods require a large difference in the maximum hot pressing time. Under the conditions of high-speed hot stamping, the maximum hot pressure time of the flat stamping is obviously longer than the maximum hot pressing time of the rotary stamping. Thus foil materials for rotary hot stamping should have easier or faster release properties than foil materials for flat stamping. It is important to choose the right hot stamping foil material according to the different hot stamping speed.
In short, we must strictly monitor the whole process of foil hot stamping processing, and process the hot stamping products with superior quality and completely meet the user's requirements, so as to win the trust of your users and establish the status of your hot stamping experts in the user's mind, so as to avoid Users question your quality of hot stamping and cause unnecessary economic losses, while also helping to strengthen the good relationship you maintain with your customers.
Whenever possible, you should choose and determine the type and quality of the hot stamping foil material you use. In the field of high-grade carton packaging foil hot stamping, if you are the most convincing expert of the user, you must strictly control the quality of the material selection and the strict process and quality control process. Allowing others to select and determine hot stamping foil material will reduce your choice, delay production and seriously affect the quality of the final product.
Your foil material supplier may be your best source of information and the best staff for the right choice and determination of the foil you need. If possible and time permits, it is a good idea to provide a sample of the stamping foil you want to stamp to your hot stamping foil material supplier in advance, so that they can provide you with the best matching hot stamping foil material.
Take time to study and understand the basics of hot stamping technology and hot stamping process, analyze and eliminate the drawbacks in hot stamping processing, and correctly select the most suitable foil material on this basis, in order to succeed in hot stamping processing , to produce the perfect product with high quality and beautiful patterns.
