CMYK color separation is a technique commonly used in printing to reproduce mutli-color images. However, the color planes are generally not perfectly aligned with respect to each other when they are rendered by the imaging stations. This phenomenon, called color plane mis-registration, causes gap and halo artifacts. Trapping algorithms aim to reduce these artifacts by scanning through an image,...

Today, natural colorants are emerging globally due to the fact that they are safer and more environmentally-friendly. Natural dyes have been employed in dyeing Persian carpet piles for many years. In this study, the dried Achillea was used for dyeing wool yarns. The Iranian wool yarn was scoured, mordanted using Cu, Sn, Al salts and then dyed with different amounts of dried Achillea powder. Tag...

Carotenoids are substantially hydrophobic antioxidants. Hydrophobicity is this context is rather a disadvantage, because their utilization in medicine as antioxidants or in food chemistry as colorants would require some water dispersibility for their effective uptake or use in many other ways. In the past 15 years several attempts were made to synthetize partially hydrophilic carotenoids. This ...

Talaromyces atroroseus is a known producer of Monascus colorants suitable for the food industry. Furthermore, genetic tools have been established that facilitate elucidation and engineering of its biosynthetic pathways. Here, we report the draft genome of a potential fungal cell factory, T. atroroseus IBT 11181 (CBS 123796).

Synthetic dyes used for the coloration of textile goods are not readily biodegradable and a major concern water pollution. Nature has abundant sources potential colorants applications. There many challenges in using natural pigments, significant research efforts currently put into replacing synthetic successfully. In order to gain insight future trajectory dyeing utilizing colorants, bibliometr...
