The quality parameters of printed sheets should be controlled constantly during the sheet-fed offset printing process. This allows the detection of any problems in the initial stages of the printing process. The final control of the quality of printing sheets will eliminate error products before delivering to the costumers. The results of this control should be analyzed continuously. The total quality management (TQM) is an effective method in controlling, doing statistics, and assessing the errors in the offset printing process. Simultaneously, this method delivers the main errors frequently occurred in the printing process. This paper presents the possibility of using some tools of the TQM method such as Pareto chart, Ishikawa diagram, and 5xWhy to analyze and assess the quality of printing sheets in sheet-fed offset printing. The studied results show that the two main errors of the printed sheets are hickeys (occupied 29 %) and low density (occupied 17%). Moreover, the causes of hickey error are analyzed and shown in this paper.

“…The values obtained from the calculation behaved in a similar fashion to the E* ab , indicating that bleached kraft liner coated with 2% nano-RHS had the lowest E* ab . The main reason why the color difference was the lowest is due to the fact that the TVI nearly met the flexographic printing standards, with low tone value and moderate density [46]. Abrasion resistance testing was conducted on all the bleached kraft liners.…”

“…The effectiveness of Random Forest model was tested by Lunströ m et al 7,8 Their studies showed that Random Forest model could provide good correlation with the print quality ranking obtained from visual analyses. The assessment and estimation of print quality was carried out on web offset (coldset) prints based on several objective parameters (colour deviation, misregistration and deformation of the raster element, optical density, tone value and grey balance).…”

Over the years, computing and information technology in the printing industry has been brought to a very high level. However, the models for assessing and estimating quality by considering print quality parameters are still being researched. This paper presents a mathematical model that was used for the purpose of enabling assessment of the flexographic print quality based on the visual experience of a standard observer. The model facilitates the assessment of print quality parameters' impact on the visual experience of the high-quality flexographic print. As a part of this assessment process, print quality measurement analysis of each ink (cyan, magenta, yellow and black) was performed by focusing on several print quality parameters; dot gain at 50%, trapping, mottling, optical density and colour gamut. The use of logistic regression analysis in this paper allowed for a definition of nine variables that significantly impact the subjective perception of the total print quality. Methodology presented in this paper can be effectively applied in the scientific and professional practice of graphic design.
