ARTICLE ANNOTATION

The article evaluates the quality of the foil-embossed image. Foil stamping is a finishing process in the production of printed products, as it is used to improve the appearance, giving it uniqueness and originality, depending on the consumer’s order. Hot foil stamping is the most popular and widespread method among the technologies used. The simplicity of the technological process and the addition of unique decorative and protective elements to printed products comprehensively provide an optimal quality-price ratio. Despite the advantages of this type of finishing, embossing technology becomes more complex due to the use of new consumables, especially new series of foils. One solution to this problem is the correct selection of the embossing mode depending on the actual production conditions and the characteristics of the materials used. For this purpose, at the printing enterprise Micros LLC, prints were obtained on coated papers with a density of 270 and 290 g/m2 using a semiautomatic crucible press. For embossing, we used a universal metallized foil designed for a wide range of paper and cardboard surfaces. The stamp temperature was varied in the range from 110 to 1200C, at a pressure of 12±1 MPa. To assess the influence of embossing parameters on the quality of reproduction, the hiding power of the embossing was studied, that is, the presence of breaks and cracks in the metallized foil layer. The degree of sealing of the die, lines of various thicknesses (from 0.2 to 1.5 mm), objects of complex configurations, positive and negative texts on the test object were assessed visually using a point system and quantitatively in pixels.
