Process for manufacturing reproduction with a luminescence effect and reproduction manufactured by the implementation of the process

Abstract

An image is reproduced on a transparent carrier and a film incorporating a photoluminescent product is applied to the carrier, either on the same side as the printed image or on the other. A filter in the form of a film allowing the effects of the color of the photoluminescent material to be moderated is inserted between the carrier and the film. The filter is a translucent material that desaturates the color of the luminescent layer by way of its light scattering capability. Light which passes through the filter is scattered uniformly thereby giving rise to a white haze, is then reflected off of the luminescent layer and then passes through filter again on its way to the eye of the viewer. Different sequences and combinations of the various layers are possible.

Description

[0001] This application is a continuation-in-part of application Ser. No. 08 / 973,592, filed on Apr. 16, 1998BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a process for manufacturing a reproduction with a luminescence effect, and to such a reproduction. [0004] 2. Background of the Invention [0005] It is currently known to make reproductions with a luminescence effect and more specifically a photoluminescence effect of the positive or negative Chinese-shadow image type or images produced using colored photoluminescent pigments. These two types of images having a luminescent effect are essentially produced using the following processes: [0006] by screen printing and optionally offset printing with photoluminescent inks which are colored or not on various carriers, such as paper, fabric, plastic or metal; [0007] by various forms of printing (screen, “pressure-pad”, offset, heat-transfer printing, etc.) on photoluminescent carriers b...

AI Technical Summary

Benefits of technology

The present invention is about a process for producing reproductions with a luminescence effect, which can be any type of image such as photographic images, technical drawings, artists' works, or logos. The process involves preparing a film with a luminescent material, preparing a translucent filter to create a cohesive interface between the luminescent material and the image, and printing the image on a surface that allows light to pass through it. The process can be used with different types of printing such as continuous-tone printing, photographic printing, or offset printing. The resulting reproduction has a high quality of detail and can store light energy optimally. The process also allows for the creation of a depth effect and a relief effect by printing parts of the image on different surfaces and in different colors. The reproduction can also include a transparent protective screen for protection against ultraviolet radiation.

Problems solved by technology

These various processes do not make it possible to produce reproductions having a very high resolution and very sharp images, which may be seen quite faithfully at night as they are during the day.

In addition, the colored photoluminescent pigments offer only a limited number of colors and their luminescence characteristics, both in terms of brightness and in duration, are limited.
