Feature Ink and toner Two key trends seen in today’s printing inks market are an increase in flexographic printing inks and the shift towards environment-friendly inks – such as water-based and UV- cured that reduce the effects of toxic materials used in conventional printing inks. Also, as more sophisticated press- es emerge, inks and toner options are becoming more specialized, especially for wide-format inkjet and textile print- ing. Two recent toner releases include Neon Pink from Ricoh, developed for the fifth colour station on its Ricoh Pro C7100X Series of digital production presses. Plus, Heidelberg now offers an optional new neon yellow spot colour for its Versafire CV digital system. This toner glows under UV light and can also be used as a security feature, since it’s almost impossible to copy. workflow and image quality. Ergo, many leading manufactur- ers have gone to great lengths to certify or recommend certain substrates for maximum on-press performance and image quality. And there are literally thousands of choices out there, especially for inkjet. However, recent years have also seen an increase in the use of specialty substrates (as opposed to purchasing expensive finishing or embellishment presses). For medium or small print- ers who don’t deal in larger runs, these specialty substrates can be a path to differentiating themselves from their competi- tors. Specialty papers are created or converted for a very specific use. They’re either manufactured separately, or normal paper is converted into specialty paper by coating it with certain chemicals, making them ideal for a specific application. These papers have specific characteristics (i.e. often lightweight with high opacity) and can play a unique role in packaging, printing, and industrial printing. One leader in this space is Illinois-based GPA Specialty Substrates. Its most recent release, for example, was an expansion of its pearlescent papers that feature a shimmering pearl-like textured surface. Synthetic substrates are also growing. New Jersey-based HOP Industries is one major player in this space. Its papers are made from polypropylene resin and calcium carbonate, are totally “tree-free” and 100% recyclable. “The synthetic paper market is expected to grow 10%-15% per year over the next five years because of the demand for more environment- ally-friendly plastics that are 100% recyclable,” said Jack Smith, senior VP of HOP Industries. “They’re also popular because of the growing trend in digital printing via laser, Indigo, UV and latex inkjet, that are extremely printer-friendly. Our Hop-Syn line is one of the most popular synthetic papers because it includes a wide range of thicknesses and grades.” Generally speaking then, synthetic papers combine the ver- satility of traditional paper with the durability of plastic, which makes them ideal for outdoor applications. They’re environ- mentally friendly, waterproof, tear, scuff, and temperature resistant, more durable than traditional papers, flexible, fold- able, and can hold colours well regardless of the printing process used. @graphicarts Of course, the most disruptive technology in this space is Landa Nanography that utilizes tiny ink pigments that absorb much more light than traditional inks. The ultra-small Landa NanoInk pigments form a very thin layer of ink and allow digital printing at very high speeds on ordinary untreated paper stocks, and on just about any plastic packaging film or label stock. The final images are abrasion-resistant and scratch- resistant – and the overall ink cost savings are huge. Also important in this space is software and technology that controls the amount of ink used for any given print project. Agfa’s wide-format inkjet printers are a leader in this area, utilizing an extremely low ink laydown that can result in major ink cost sav- ings for printers – all without sacrificing print q u a l i t y. A l s o key i n reducing ink waste are devices such as ink dispensers, ink levellers, agitators, foun- tain liners and dosing equipment, which have proven their worth over the years. In the end, it’s all about cutting costs by reducing consumable and substrate waste while maintaining optimal print quality In the end, it’s all about cutting costs by reducing consumable and substrate waste while maintaining optimal print quality. And if you investigate further, you’ll discover that the cost savings over a year can really add up. Look at it this way: If you buy just one coffee each morning that costs from $3 to $5, you’ll be spending from $1,095 to $1,825 a year. So you see, consuming consumables can be an all-consuming (and costly) habit. Tony Curcio Editor, Graphic Arts Magazine [email protected] GRAPHIC ARTS MAGAZINE | October 2018 | 35
