“…However, this presents a potential issue within the United States. In Europe, printers have broadly adopted polarized densitometric readings [5][6][7] which are not commonly found in the standard operating procedures in the US. 8 Introducing polarized densitometry into an environment where unpolarized densitometry is utilized can be problematic.…”

Automated color measurement systems have become significant components of offset lithographic printing presses for better process control and reduced job waste. Some European press manufacturers are known to offer automated color measurement equipment that is confined to polarized density readings, which is uncommon in US. Introducing polarized densitometry into an environment where unpolarized densitometry is utilized can be problematic. Print professionals are on the lookout for a solution that is evidenced by a recent feature in a post from the IDEAlliance G7 Professionals forum seeking for a methodology to convert polarized to unpolarized readings. The present study applies the Bland-Altman method together with other statistical analyses to determine if a conversion between polarized and unpolarized densitometry can be established within a limited set of parameters. Three spectrodensitometers were used to record densitometric readings of wet and dry process inks on coated and uncoated drawdown proofs. The results showed that coated papers had significantly less variation between instruments compared to uncoated papers. Wet inks had more minor variations compared to dry inks. Furthermore, pure difference values and a Mann-Whitney U test indicated differences between unpolarized and polarized densitometric readings in all cases. Finally, t-tests performed on the resulting difference data for both unpolarized versus polarized and unpolarized versus predicted polarized that showed fixed bias by means of the computed p-values.

“…This maritime pine genus, which is geographically distributed, genetically diverse, and tolerant to ecological conditions, contains a large amount of resin (Çiçekler et al, 2018). Recent research has reported the use of various genus of pine resin in printing ink formulations, demonstrating the suitability of this renewable raw material (Hayta et al, 2020, 2021; Karademir et al, 2020). Throughout history, pine resin ( Pinus spp.)…”

The oils and solvents are the main components of the printing ink, and the chemical composition of the ink could be harmful or toxic to human health and the environment. Therefore, there is an increasing demand to develop inks containing green, biobased, sustainable, and renewable raw materials instead of petrochemical substances. In this study, flaxseed oil (FO), pomegranate seed oil, plum kernel oil (PKO), and grape seed oil (GSO) were selected to produce offset printing inks. Pinus pinaster (P. pinaster) resin was also used in the formulation of inks to examine the effects of natural resin on ink together with vegetable oils. The phenolic content was analyzed for the resin and oils to figure out their potential antioxidant and bioactive characteristics. Optical and rheological tests were applied to evaluate the printability of the inks. L*a*b*, ΔE, density, and gloss tests were performed for optical evaluation. The viscosity, tack, and rub resistance tests were applied to perform rheological analysis. The biobased, environmental friendly, and self-drying (cold set) offset printing inks were obtained using natural pine resin and three different plant-based oils FO, PKO, and GSO. The printability analysis of the inks figured out the potential usage of plant-based oils in the offset printing ink formulation.

Background:The market for edible flowers has grown exponentially due to consumers demand. This has been motivated by the concern to include healthier foods in the daily diet, leading to a great interest in these natural matrices. However, and although the consumption of this type of matrices are popularly associated with health benefits, scientific studies are still scarce. The industry seeks to satisfy the consumers demands and, at the same time, seeks to launch new challenges in the sector, in order to outline new conservation and production strategies. Although there are several flowers with edible potential in nature, many are still little explored or unnoticed, so this type of study is increasingly sought after. Scope and approach: The present review intendeds to explore the context of edible flowers as well as their conditions of production and consumption. Then, focusing on the characterization of the genus Impatiens, which, although is still little explored, gathers data on its chemical and nutritional characterization, bioactivities, and the possible exploration of natural pigments and industrial application. Key findings and conclusions: Several studies have been focused on the chemical characterization of flowers, evaluation their edibility, as well as validating their bioactive potential. In particular, the genus Impatiens is characterized by presenting perennial and succulent herbs with attractive colors, normally found in tropical forests. There are countless studies on the bioactive activities present in these edible flowers. In addition, its pigmentation has a direct relationship with the presence of several compounds, especially anthocyanins and their derivatives. These bioactive compounds have a great interest to the food industry and consumers, due to their diverse health benefits that are provided by their regular consumption.
