Optical density measurements are critical for process control and quality assurance during print production. Use of scanners and cameras for color correction and colorimetric measurements have been reported earlier in literature. This paper presents a procedure for using a scanner as a densitometer. Density of printed patches were calculated using the pixel intensity values obtained from scanning a test target. Optical density was measured simultaneously from a densitometer and also computed from the L* measurements for the same patches. Four regression algorithms were used for modeling the behavior of the scanner using these two models. The models were tested and validated. The accuracy and performance of these models were compared. Results convey that the scanner can indeed be used for taking densitometric measurements obtained from the L*, under the presented method.

Keywords: densitometer, process control, print quality, regression, machine learning

The choice of printing method for this or other print product depends on many factors and, in particular, on the type and characteristics of a publication such as its volume, and the urgency of an order. The optimal selection from the available methods variety strives to get the best “price–quality–time” ratio. The issues with finding the best solutions to achieve the set goals with limited resources have always been faced by people. The concept of decision-making considers a decision a conscious choice of one of many options. At present, in connection with the growing needs of practice, an interdisciplinary scientific direction is actively developing. One of its sectors is the mathematical theory of decision-making under many criteria. With the exemplary choice of a particular print job (publication), the multi-criteria task of printing technology choice and the effect of a job volume on the cost and time of its manufacture are considered in the light of Edgeworth–Pareto principle.

Sri Lanka’s media landscape follows the global broadcasting industry’s popularity. Digitalization has had the greatest impact on the sector and all its usage scenarios. Therefore, the primary goal of this study is to ascertain how Sri Lanka’s broadcast business would be impacted by the digital revolution. This study seeks to uncover the factors that influence the media industry’s transition to a digital model and determine how much viewers, broadcasters, content providers, and infrastructure in Sri Lanka depend on public digital media use. A standardized questionnaire has been administered to reach the goal. From a sample of 1 174 respondents in the Western Province, information about the nine research constructs was gathered using previously validated instruments SmartPLS 3 and the SPSS 26 that were used to systematically assure the empirical validation of the theoretical model. The conceptual framework did not match the research’s real-world reality. Digital broadcasts and digital literacy affect broadcasters’ digital uptake. User device availability, price, and perceived ease of use mediate the intention to use a digital device. Perceived usefulness partially mediates broadcast user digital adoption. Age and gender moderating variables, produced from solid empirical findings and fully excluded from the study, established a new field of study for the literature. The findings also omit the independent policy on digitalization variable. Hence, the study showed that its survey results had a considerable impact on the conceptual model compared to past empirical investigations, and most importantly, it opened up a new field of knowledge for future research. Lastly, the study’s findings were discussed and recommendations are provided. Sri Lanka’s media industry’s digital transformation will benefit from applying the research’s findings. The proper application of the research’s conclusions will improve the sector by bringing about several advantages for Sri Lanka’s media industry’s digital transformation.
