The result of the paper and the quality depends on various interconnected mechanical, physical and chemical processes what are affected by material properties, reset technologies, equipment and the condition of the production premises in the Print industry especially in the printing processes. Due to the complicate technological processes different defects can appear during the printing process which reduces the quality of production and causes financial loss. One of the main leading Printing company of Latvia “Livonia Print” initiated to explore and find solutions – to reduce or eliminate the risk of GH. GH has not been sufficiently studied so far. Consequently, there is not much specialized, professional literature available. Research sample of printing is taken from a real order, album, and it was printed under real production conditions. The result of the research is to reduce or completely eliminate risk of GH occurrence in the production of high-class printed works (albums, catalogues, etc).
