Offset (imprimerie)Index. décimale : 667.4 Encres Résumé : The lithographic printing industry continues to face challenges, including volatility in raw material cost and eroding markets in Europe. Incorporating kaolin, or China clay, in offset ink formulation - both coldset and heatset - can help optimise the ink formulation in terms of cost-performance. A new kaolin grade has been developed to give significantly reduced clay bleeding or washout with fount solution. Note de contenu : - Optimised pigment dispersion and resin extension
- Interest in kaolin's fine platey structure
- Improved ink-found emulsification
- Kaolin advantages in offset inks and beyondEn ligne : https://drive.google.com/file/d/1Z04jvP-6rtoIkgwah7x8vepsI2KEcznN/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=21700

MahiIndex. décimale : 667.4 Encres Résumé : Mahi, a unique herbal ink used in medieval Assam in India for writing and illustrating manuscripts, is known for its intense colour and durability for centuries, and its non‐corrosive nature. Mahi is distinctly different from the other contemporary inks used elsewhere in the world, including other parts of India. The interesting features of Mahi are due to its special recipe involving several herbal ingredients in addition to iron sourced from fish blood or the rust of iron tools, with cow urine as an extractant and solvent. The objective of the current study is an in-depth understanding of the traditional method of the preparation of Mahi, and its characterisation through analysis of the physicochemical properties using spectroscopic and imaging techniques as well as biochemical analysis. A series of model Mahi samples are prepared following the traditional method with varying ingredients, and their compositions and physicochemical properties are evaluated with respect to the ingredients using standard methods and analytical tools including atomic absorption spectroscopy, tensiometry, ultraviolet (UV)-visible, Fourier Transform-infrared (FT-IR), Raman, steady-state fluorescence, UV fluorescence and emission microscopy. The colour of the ink has been attributed to various polyphenols, gallic acid, epigallocatechin gallate, epicatechin, quercetin, kaempferol and tannic acid, and their iron complexes. UV fluorescence and emission microscopy confirmed an autofluorescence indicative of the presence of phenolic and chlorophyll pigments. Solubilisation by glycosidic biosurfactant contributes to stabilisation of Mahi. The non-corrosive nature of Mahi has been attributed to its neutral pH and absence of free iron and copper ions.

TatouageIndex. décimale : 667.4 Encres Résumé : Body artists in Europe may have to reconsider the pigments that they use in future, with the European Union (EU) drafting new rules that could regulate what chemicals can be used in tattoo inks. While today 12 out of every 100 Europeans are tattooed or have some sort of permanent cosmetic treatment, experts are increasingly concerned that these skin colouring agents may contain hazardous substances, known or suspected to have adverse health effects causing cancer, allergies or mutations. As a result, the EU executive, the European Commission has asked the European Chemicals Agency (ECHA) to investigate, evaluating whether EU consumers' health is actually under risk from tattoo insk and advising on whether EU legislation is necessary. "The EU is not (considering) banning tattoo inks or tattooing but aims to ensure that all substances present in tattoo inks are safe for citizens", a Commission spokesperson underlined.

Règlements de sécuritéIndex. décimale : 667.4 Encres Résumé : Food packaging and food contact materials are an important element in the overall effort to provide consumers worldwide with safe and nutritious food. Chemical compounds that are incorporated in printing ink, laminating adhesives and polymeric packaging materials to improve functionality, may interact with food components during processing or storage and migrate into the food. Once these compounds reach a specified limit, food quai ity and safety may be jeopardized. Migration limits have been set for many substances based on the toxicological risk assessment of these substances. These limits are included in Food Contact regulations with the aim to control the exposure to these substances to protect our health. It is a mandatory requirement for consumers to determine impact of packaging in contact with food on food safety. However, Printing ink and packaging manufacturers must be prepared to deal with a complex global regulatory landscape, in which individual jurisdictions have adopted different regulatory frameworks for the review and approval of food packaging and food contact materials and issue compliance declaration. The Glocal and Global regulations of Printing Inks on Food Contact Materials are not fully harmonized. It varies region to region or country to country even customer to customer. The approval process can be further complicated by customer procurement requirements based on voluntary standards promulgated by industry and trade groups, as well as by the specific substances used in printing ink and packaging materials.
