As printers, we obsess in the pursuit of perfection, such as on the spectrum of color. But there is a different spectrum that is perhaps even more difficult to master, and for which alignment is even more critical: the Cultural Spectrum.
Brands and their associated colors are often so closely connected that consumers can quickly recognize a brand based solely off color - think Coca-Cola and red. In packaging, color differentiation is often measured in terms of "Delta E," with the goal to keep that number as low as possible. But what exactly is Delta E, and how can printers better understand this essential measurement?
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.
