Abstract

The present disclosure generally relates to printed structures and methods for generating the same. The printed structure includes a first surface including a first ink type arranged in a first image and a second surface at least partially aligned with at least a portion of the first surface, the second surface including a second type of ink arranged in a second image. The first and second surfaces are physically separated from one another, the first image is visible under a first set of light wavelengths and the second image is visible under a second set of light wavelengths.

Background

TECHNICAL FIELD

The technology described herein relates generally to methods and systems for generating printed images.BACKGROUND

Inks containing florescent pigments are often used to enhance or alter the observed colors of printed images. The fluorescent inks are excited when illuminated with specific wavelengths, (most often out of the ultraviolet “UV”) spectrum, and may exhibit increased brightness and saturation compared to the reflection of standard cyan, magenta, yellow, and key (black) “CMYK” or cyan, magenta, and yellow “CMY” inks. When normal visible illumination conditions are applied, fluorescent inks can have a variety of different appearances such as transparent, diffuse white, or colored depending on the manufacturing process, and chemical components. Because of the wide range of color-alteration or enhancing effects, prints containing florescent inks are widely used in many fields including art, entertainment as well as optical documents security.

UV prints are typically limited to effects such as enhancing already printed colors (e.g., making the colors brighter and more vivid such as when saturated under UV light), or to reveal hidden images. However, when used to reveal hidden images, the intensity of the colors strongly depends on the type of print surface used. For example, when invisible florescent inks are printed onto a surface covered with black ink, the output will be much darker than compared to when printing the same florescent ink

Claims

1. A printed structure comprising: a first surface comprising a first ink type arranged in a first image; and a second surface at least partially aligned with at least a portion of the first surface, the second surface comprising a second ink type arranged in a second image; wherein the first surface and second surface are physically separated from one another; the first image is observable under a first set of light wavelengths; and the second image is observable under a second set of light wavelengths. | 11. A method for generating a print with a different appearance under different lighting conditions, comprising: generating by a processing element a color prediction model representing achievable color ranges for one or more color alteration effects for a first input image and a second input image; evaluating the color prediction model for the first input image and the second input image to determine artifact areas; reducing a color gamut in the artifact areas of at least one of the first input image and the second input image to generate a first output image corresponding to the first input image and a second output image corresponding to the second input image, wherein the first output image and the second output image have fewer artifacts under at least one of a first light condition or a second light condition as compared to the first input image and the second input image; and printing the first output image and the second output image. | 15. A method of printing a structure with different appearances in different lighting conditions, the method comprising: printing a fluorescent ink on a first surface; and printing a visible ink on a second surface, wherein the first surface is physically separated from the second surface.
