The Success of Aqueous Coatings The use of aqueous coatings by the printing industry is, without doubt, a success story that now sees many millions of pounds of coating used annually to protect and enhance the printed material. This success has not always come easy, as the processes of printing involve many variables which must […]
Substrate Options Superior folding cartons begin with the proper choice of substrate, paperboard with the performance and graphics quality to successfully market the packaged product. The wide variety of substrates available to the folding carton producer make it easy to make the wrong choice. Converters must carefully assess printability, packaged product protection, package design requirements, […]
Flexo Style Chambered Doctor Blade Metering Coaters Flexo style chambered doctor blade metering coaters have become the dominant coater type used on sheet fed offset presses. They have proved capable of producing high levels of precise, repeatable application of clear coatings, and other fluid products. Integral to this success has been the development of the […]
Nearly 7 million tons of coated paper, paperboard, and cardboard, are manufactured worldwide annually. The dominant coating material is petroleum based polyethylene (PE). Currently, alternative coating materials that don’t cause environmental harm throughout their life cycle are being sought because of consumer, political, and legislative pressure to reduce fossil fuel based plastics use.

Setting & Drying Inks It’s all about the setting and drying of conventional sheet fed offset inks. Anti-set-off spray powder is used to prevent set-off, the unwanted transfer of wet ink to an adjacent sheet, in a press end pile. Spray powder not only provides a physical spacing between sheets of substrate, but also allows […]
