Research on the Quality of Foiling in Jobbing and Blank Forms Printing

The article is devoted to the study of the quality of foiling in jobbing and blank products, taking into account the technological parameters that determine the stability and efficiency of the finishing process. The paper analyzes the usage features of hot and cold foil stamping, as well as materials for decorating small­format products, which are characterized by a wide variability of design and increased requirements for accuracy of execution.
The research methodology is based on an experimental study of the quality of foiling on jobbing and blank products. The reproduction­graphic and printing­technical parameters of the prints obtained during the foiling process were measured, and the microscopic analysis of the cross­section of the structures after foiling was performed. The results obtained allowed the authors to determine the optimal embossing mode to ensure high stability of the foil transfer and the formation of clear, contrasting and durable decoration elements.
The article formulates practical recommendations for optimizing the foiling process parameters, in particular the choice of temperature regimes. The conclusions presented can be used by printing companies to improve the quality of special­purpose and jobbing and blank products, improve technological maps and predict the quality of decoration depending on the properties of the selected materials. The conclusions of the study can be used to develop technological maps, standardize quality parameters and improve production instructions in the field of post­printing processes. The results obtained are of practical importance for printing companies specializing in high­quality decorative finishing, as they allow minimizing losses associated with defects, increasing the stability of the foiling process and ensuring the reproducibility of quality indicators regardless of the complexity of the layout or manufacturing conditions.
