Abstract

Wrapping heat-deformable plastic labels around packages relies on a shrinking process. Shrinking plastic labels distorts not only the shape but also the color of the printed artwork. In this work, we analyze and model the color shifts induced by shrinkage. The ultimate goal is to generate full color images which after shrinking have colors as close as possible to the original colors. For this purpose, we present a thickness enhanced Clapper-Yule prediction model. Its calibration requires spectral measurements of original, non-shrunk samples as well as the measured shrinking factors. With the prediction model, we establish a table creating the correspondences between target colors after shrinking and ink area coverages. This enables creating color images which after shrinking match the original images.

Color printing

Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color.

Color

Color (American English) or colour (Commonwealth English) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra and interference. For most humans, color are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelength, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range.

Color theory

In the visual arts, color theory is the body of practical guidance for color mixing and the visual effects of a specific color combination. Color terminology based on the color wheel and its geometry separates colors into primary color, secondary color, and tertiary color. The understanding of color theory dates to antiquity. Aristotle (d. 322 BCE) and Claudius Ptolemy (d. 168 CE) already discussed which and how colors can be produced by mixing other colors. The influence of light on color was investigated and revealed further by al-Kindi (d.
