Curtis Packaging Introduces InvisibleDOT™, A Printing Breakthrough That Provides Superior Detail And Smoother Gradations Than Conventional Screening

Sandy Hook, CT- Continuing its long history of technological innovation, Curtis Packaging introduces InvisibleDOT ™, a breakthrough printing process that will produce significant benefits for the design and manufacturing of customized folding cartons. The new development is a variation on Frequency Modulated (FM) Screening and simulates Continuous Tone Printing by providing superior detail and smoother gradations than conventional screening. The technique reduces variations in color and is especially useful when realistic reproduction is required for the packaging of such products as hair color, confectionery and organic goods.

“The entire InvisibleDOT development process, from inception to its regulatory trademark, took eight months,” says John Giusto, Curtis Packaging’s VP Manufacturing. “and is both practical and cost effective for all segments of the packaging market.” He points out that because the technique enhances the detail of process shots, it is especially beneficial for applications in which the reproduction of flesh tones is a requirement. “Previously, with conventional methods,” Mr. Giusto adds, “images were susceptible to screen angle patterns, whereas now we can produce a smooth gradation in all tonal values.”

The process has proven successful on both coated and uncoated substrates, holds color well over an entire run, and facilitates the availability of makereadies in a much shorter time span. In addition, production costs with InvisibleDOT are slightly less than with traditional screening methods, and established schedules remain unaffected. “The process also creates a close ink/water balance,” says Mr. Giusto “and tighter tolerances than traditional screening.”

In addition to Cosmetics, Health and Beauty Aids, and Food or Confectionery products, InvisibleDOT has application for Giftware packaging and, because of its highly effective performance, Curtis will eventually transition all screening projects to the process. “InvisibleDOT is compatible with the established parameters of sustainable packaging, and our strong commitment to the environment,” stated Don Droppo Jr. Vice President Marketing.”
