The use of cellophane in post-printing applications has an important role in increasing the strength properties of the product and maintaining its visual quality. In the majority of cardboard packaging production, cellophane coating is applied in order to protect the structural features of the packaging during the shipment, storage and sales process. Cellophane coated without using the right parameters causes color differences in inks with low nitro resistance. Adverse situations affect the quality of the packaging and cause entanglements between the manufacturer and the customer. In this study, glossy and matte cellophane was applied on the test scale printed cartons prepared in the production facility where cardboard packaging was maintained under real production conditions. According to iso12647-2 prints, homogenous cellophane was first controlled visually. Densitometric and spectrophotometric measurements were made; dot gain, color change and color universes were measured and these values were examined with graphs and tables. As a result, it was determined that cellophane coatings applied on cardboard packaging printing increased dot gain values, expanded the color universe, and especially bright cellophane application provided a wider color universe.
