Marketing Gravure
Laura Wayland-Smith Hatch, GravurExchange
It was ten years ago that I first became involved with the gravure industry, joining one of the trade associations and assuming the helm of Director of Communications. And, at that time, I first heard the question—what are we doing to market the gravure process?
PLGA Global Gravure Specifications Update
Laura Wayland-Smith Hatch, GravurExchange & Claus Zack
During the month of May, four telephone conference calls were held—two focusing on Design & Prepress and two focusing on Print—to review materials and make some new assignments of topics to individuals.
What do you know about sheet-fed gravure?
Laura Wayland-Smith Hatch, GravurExchange
Sheet-fed gravure printing—well known in Europe and elsewhere around the world is starting to make inroads in the North American market. Its versatility, quality, and economies are attractive to not only packaging printers/converters, but also the label, stamps, and securities segments of the industry.
Density & Dot Gain
Dimitris Ploumidis
Density has traditionally been used as the primary means to control the printing process. It has been widely held that it correlates well with the amount of colorant that is put on the paper over a limited range of ink film thicknesses. In addition, it is a convenient metric to use in a production environment, since it provides insight through a one-dimensional variable by which press operators can judge whether too much or not enough ink is being laid on a given substrate.
From Green to Great
JoAnn Hines, Packaging Consultant
It’s hard to separate fact from fiction about what is considered truly “sustainable” packaging. Every company has a different take on what they deem to be the solution. Some are just spin while others have real substance. Green, sustainable, biodegradable, recyclable, compostable, renewable and so on. The list is endless and new terms surface every day. Bio-resins bio-plastics, eco-friendly—you name it. But whatever the term may be, it needs to be relevant packaging to YOUR customer.
The Effects of Electrostatic Assist on Gravure Printability
Miles A. Haney, Western Michigan University
In this work it was determined how changes in the electrostatic assist levels affect the optical density and dot gain of gravure printed documents. Optical density and dot gain of elongated and compressed cells at different ESA (electrostatic assist) settings were also compared in this experiment. Two test targets at four different ESA settings were printed on a Cerutti four-color rotogravure press. Dot gain and optical density were measured for six tone steps of elongated magenta cells, compressed magenta cells, elongated cyan cells, and compressed cyan cells. For optical density values of compressed and elongated cyan and magenta for each ESA setting, elongated starts with a larger density value, but as the tone step is increased, optical density values become larger for the compressed cells than that of elongated. Elongated cells are shown by this experiment to produce higher dot gain for both magenta and cyan than that of compressed. Elongated cells for both magenta and cyan showed a more stable trend of dot gain with less deviation than that of the compressed cells.
