National Graphics lands lenticular patent
Jan 24, 2007 3:43 PM
National Graphics, Inc. (Brookfield, WI) was issued US Patent No. 7,136,185 “Corresponding Lenticular Imaging.” “Correspondence” in this instance pertains to the relationship between an interlaced image and the lenticular lens to which it will be applied.
Lenticular images are comprised of “strips” from a series of files arranged in a particular order to form what is commonly known as an “interlaced” image. This interlaced image needs to “correspond” to the lenticular lens.
When fitting an interlaced image to the lens, viewing distance, surface curve, pitch variances, press or print size changes due to mechanical phenomena of the printing press or output device, and atmospheric conditions are among the items which must be considered to maximize image quality.
Most lenticular lens material is manufactured utilizing an extrusion process. Within this process are the variables of heat, pressure, speed and tension. Each of these variables can contribute to variances from extrusion run to extrusion run, as well as within any given run.
The invention disclosed in US Patent No 7,136,747 provides a solution that allows the output resolution to be altered in anticipation of variances such as those noted above and taking control of the timing of the output device. NGI’s patent describes how the resolutions of the lenticular lens, the interlaced image and the output devise are put in harmony with each other thereby reducing image degradation.
The result reportedly is high-quality image output characterized by increased clarity; reduced blurring and distortion; and less disjointed and more contiguous illusions of motion and depth.
