Since people's satisfaction with products increases in daily life, manufacturers often need to consider many details, such as product packaging. In the process of printing and packaging, every detail problem may affect the quality of the final product. So, what problems might arise after printing and printing? We will briefly analyze for you:
First, the process is backward
The binding process after packaging and printing is still relatively backward, and the most commonly used wire is the flat wire based on manual labor. In addition, there are two ways of glazing, one is glazing and calendering, and the other is UV glazing. Nowadays, glazing technology is gradually drying technology from liquid glazing paint to solid state, but using solid-state drying technology, the internal surface of the glazing process cannot be dried while drying, and if it continues processing, it may affect the color of the ink layer.
Second, equipment defects
In the post-work process after packaging and printing, the temperature control during manual binding, few binding machines have automatic adjustment function, which may cause poor drying and poor deformation when the temperature is low. If the temperature is relatively high, there may be problems such as local sharp shrinkage or voiding of the film surface.
Third, the material is outdated
The adhesives used in the manual binding process are all hydrated and the concentration may be non-standard. It may cause unstable adhesion, shrinkage after drying, and rusting of the wire nails.
In addition, it is composed of binder hot melt adhesive, film adhesive, glazing paint and the like used in the post-work process after packaging and printing. This material and technology are basically materials that have been eliminated by foreign advanced international.
In addition to the above-mentioned problems that may occur after packaging and printing, it may also cause other problems due to technicians' mastery of mechanical equipment, lack of necessary knowledge, maintenance of machine equipment, and adjustment skills.
