Sažetak
The main goal of the packaging production process is to ensure quality reproduction of color and design in general, so that the quality of the final product meets all requirements necessary for food packaging. Colors are one of the key components of brand recognition and the creation of an emotional connection with consumers which is the basis of this paper. Aside from conventional packaging materials, more and more food products are marketed in multi-layered flexible packaging. The samples that form the basis of this paper are printed on polyester film (PET) using a rotogravure printing technique. During the finishing phase, the PET layer are laminated on layer of aluminium (Al), oriented polyamide (OPA) and polypropylene (PP) and then, after cross linking, they are die-cut and formed into stand-up pouch. During the graphic reproduction, graphic preparation, printing and finishing processes, colors show various deviations. The main goal of this paper is to examine the influence of the individual phases of these processes on the manner in which red spot color reacts to and determines deviations (ΔE*) in relation to a defined formula and color standard. Color deviations may also occur during the finishing and sterilisation process. In order that colorimetric spot colors may be monitored, it is necessary to define a formula and standard and conduct measuring after each stage of the graphical process in the CIE L*a*b* color space. Based on the measured results, guidelines and recommendations were produced for the correction and control of color reproduction throughout the defined process which aim to reduce deviation to an acceptable level.
