The variety of flexible substrates utilized in packaging have different needs throughout the printing and converting processes. Understanding the nuances of these materials will help ensure the best results on press.
Flexo plates have a tough job, whirring around on a print cylinder, covered in ink and repeatedly transferring an image to a substrate. But to make sure these plates can withstand the high-impact nature of printing, they require delicate care and maintenance.
What does it take to keep an offset printing press performing consistently? It's a question I have been asked more times than I can count — and with good reason.
As the demands for quality and consistency have increased for brand owners, the need for inspection systems has gone from a luxury to a necessity for converters.
It’s easy to take for granted that in any type of printing, ink will meet the substrate as it passes through the press and a printed product will come out on the other side. But, what often gets overlooked is the path the ink takes on its journey to and through the press and eventually, onto its intended surface. Ink systems, whether pumps, dispensers, tanks or formulations, are crucial elements that play a major role in print quality, efficiency, color accuracy and plant and product safety.
Embossing elements on labels and packages can — literally and figuratively — add a new dimension to a substrate. A raised surface, especially when combined with foil or varnish, does provide visual enhancements, but can also enhance the chances a consumer will touch the package, greatly increasing the likelihood of a purchase.
Though they are often overlooked in the flexographic and gravure printing processes, doctor blades are essential to high-quality print results. Experts in doctor blades and chambers shared their insights on how to care for and maintain these important tools in flexo and gravure printing.
Conventional and LED-UV curing each offer their own distinct advantages, giving converters a lot to explore when making a decision.
Technological advances have yielded drastic improvement in color matching precision, regardless of the substrate. This uptick in quality assurance, coupled with the better known benefits of printing POP displays directly on corrugated — most notably, significant cost-savings and greater speed to market — has helped Sutherland Packaging, turn many potential customers into actual ones.
