One in-plant manager commented, “Inkjet saved our shop. Commercial and transaction were the only segments reporting any level of dissatisfaction at 3% and 4%, respectively. In addition to this high level of overall satisfaction, direct mail, inplant and publication respondents reported no dissatisfaction at all. Overall, printers in all segments are very happy with their investments with 86% being “Satisfied” or “Very Satisfied” with their move into this market. About 80% of printers with inkjet printing equipment have owned it for a year or more, and more than 50% have owned it for more than three years, emphasizing how production inkjet printing has rapidly become an established industry technology. Printers that own production inkjet printing equipment have been running their device(s) for years. In the summer of 2017, more than 700 commercial, direct mail, in-plant, publication and transaction printers were contacted by NAPCO Research via online surveys and phone interviews to identify their first-hand experiences, challenges and rewards regarding production inkjet printing technologies why they have adopted continuous-feed and cut-sheet production inkjet printing technology and for those that have not, why not.Ībout half of the printers surveyed say they own one or more production inkjet printing presses. To address these questions, SGIA commissioned NAPCO Research to develop a research study to explore the production inkjet market. Who owns an inkjet press? Why did these organizations decide to take a chance with this technology? What was their deployment experience? How did it impact their businesses? Still, many printers have questions about the technology. In the in-plant world, interest is on the rise, with several inkjet press installations scheduled for this year. It may not be new anymore, but production inkjet printing is still the talk of the industry. New research explores the experiences, challenges and rewards that production inkjet press users have encountered. Our work demonstrates an effective strategy to mitigate fouling and chlorine stability issues in NF membranes as well as validate inkjet printing as a versatile technique for the formation of advanced nanomaterial based membranes with high controllability of membrane properties.In-Plant Impressions - March 2018 Who Is Really Adopting Production Inkjet Printing Technology? Furthermore, chlorine resistance of the PDA-GO printed membrane showed reduction in salt rejection was effectively suppressed compared to the control membrane for the chlorination time of 1 and 3 h. Moreover, the PDA-GO printed membrane exhibited enhanced anti-fouling properties where only 20% of permeate flux reduction was observed while the control membrane displayed significant reduction in flux up to 48%. The NF test results revealed the PDA-GO printed NF membranes exhibited higher salt rejection while achieving slightly lower permeate flux compared to control membrane. Therefore, in this work, a thin film composite (TFC) NF membrane was modified by coating a binding agent polydopamine (PDA) and graphene oxide (GO) using a simple and scalable inkjet printing process where the GO deposition was controlled by the number of printing cycles. Conventional polymeric NF membranes often suffer from fouling issues and poor stability under chlorine based chemicals.
Anti-fouling properties and chlorine resistance nature are highly desirable features for membranes used in nanofiltration (NF).
