Much attention from the point of view environmental protection is paid to process manufacturing photopolymer flexographic printing plates, where waste saturated with washout components solutions that pose a potential hazard environment and require introduction additional measures for disposal or regeneration. Washout are mixtures organic solvents composition, which can be regenerated reuse. Dis...

Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...

Perovskite solar cells have potential to deliver terawatt-scale power via low-cost manufacturing. However, scaling is limited by slow, high-temperature annealing of the inorganic transport layers and lack reliable, large-area methods for depositing thin (< 30 nm) charge (CTLs). We present a method ultrathin NiOx hole (HTLs) pairing high-speed (60 m/min) flexographic printing with rapidly anneal...

the aims of this study were to determine hippuric acid and toluene in urine samples, airborne toluene levels, health effects, and to describe any correlation between specimen samples. seventy-five printing workers exposed to toluene at work (exposed group), and 60 nonexposed people (control group) were studied. study participants were selected from same factories in the different positions. uri...

Abstract Printed metal oxide devices have been widely desired in flexible electronic applications to allow direct integration on foils and reduce waste associated costs. Especially, semiconductor made from non-critical raw materials, such as Zn, Sn (and not, for example, In), gained significant interest. Despite considerable progress the field, upscale requirements lab fab scale produce these m...

Controlling the occurrence of defects is a major challenge for manufacturing organizations that are seeking to enhance their competitive position in today’s global market. This paper considers the process of screen-printing T-shirts using hydraulic and pneumatic printing machines. Several defects in the output of this printing process have been observed, especially with multi colors printing as...

printing and packaging industries make three phases of solid, liquid and gaseous contaminants which can cause very dangerous problems. the presence of alcohols, inks, and cleaners can result in massive range of industrial pollutants. always respiratory problems, fatigue, dizziness, weakness, abnormal behavior, memory impairment, insomnia, loss of appetite, and impaired vision and hearing and ca...

The advent of 3D printers has been embraced globally within few years of its emergence. The surge in the acceptability of rapid manufacturing RM technology can be attributed to the depletion and cost of natural resources, waste reduction and sustainability criterion of manufactured parts. This rapidly evolving 3D printing technologies is predicted to grow exponentially especially for the manufa...
