Abstract

Abstract A method for printing fine or commercial art utilizing visible and/or invisible fluorescent colorants and non-fluorescent colorants in a multiple series of colorant applications with each color application being made with with a predetermined print pattern. As used herein, "fluoresecent colorants" are those which emit visible light under the ultraviolet (black light), including those which are colored and those which are colorless under visible light. The colorants are applied to a base in layers or by blending the fluorescent and non-fluorescent colorants to achieve a predetermined piece of art work. Some of the layers of colorants are used to mask, or partly mask, the brilliance of some of the fluorescent layers, in graduating degrees for viewing under ulrtraviolet observation, or viewing in other lighting conditions. The proportions of the fluorescent and non-fluorescent colorants are also selected to provide a final print which can be displayed under visible and black light conditions and combinations of visible and black light illumination, depicting a subject under day and night illumination with a smooth transition therebetween such as twilight. This colorant application method can also be used to create brillant contrasts in theatrical or other stylized effects.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 253 words
The method of preparing, by a printing process, fine art having the characteristic of depicting a subject under markedly different light conditions with a smooth transition therebetween when observed under illumination varied from daylight or incandescent visible to ultraviolet black light which comprises applying to a base a multiple series of color applications with a plurality of silk screens, each application made using a predetermined pattern, and utilizing in said series of color applications, black light or visible light fluorescent colorants in a solid form as a pigment or dispersed in finely divided solid plastic particles, by applying in multiple applications to preselected areas of said base the aforesaid colorants in preselected colors and proportions, and using at least one black light pattern to simulate a night, illuminated view of said subject matter and printing thereover non-fluorescent colorant inks in preselected colors, and proportions, and in a visible light pattern distinct from said black light pattern to simulate a day illuminated view of said subject matter, and said fluorescent and non-fluorescent colorants used in proportions to blend said fluorescent colorants into the non-fluorescent colorant visible light pattern, thereby masking the presence of said fluorescent colorants under visible light observation and providing a final product that simulates a day illuminated view of the subject matter under visible light and a night illuminated view of the subject matter under black light with a smooth transition therebetween as the illumination is varied from visible to black light illumination using various proportions of visible and black light.
Claim 2
Independent Claim 253 words
The method of preparing, by a printing process, fine art having the characteristic of depicting a subject under markedly different light conditions with a smooth transition therebetween when observed under illumination varied from daylight or incandescent visible to ultraviolet black light which comprises applying to a base a multiple series of color applications with a plurality of silk screens, each application made using a predetermined pattern, and utilizing in said series of color applications, black light or visible light fluorescent colorants in a solid form as a pigment or dispersed in finely divided solid plastic particles, by applying in multiple applications to preselected areas of said base the aforesaid colorants in preselected colors and proportions, and using at least one black light pattern to simulate a night, illuminated view of said subject matter and printing thereover non-fluorescent colorant inks in preselected colors, and proportions, and in a visible light pattern distinct from said black light pattern to simulate a day illuminated view of said subject matter, and said fluorescent and non-fluorescent colorants used in proportions to blend said fluorescent colorants into the non-fluorescent colorant visible light pattern, thereby masking the presence of said fluorescent colorants under visible light observation and providing a final product that simulates a day illuminated view of the subject matter under visible light and a night illuminated view of the subject matter under black light with a smooth transition therebetween as the illumination is varied from visible to black light illumination using various proportions of visible and black light.
Claim 3
Dependent Claim 23 words
The method of claim 1 wherein said applications of said non-fluorescent colorants are made with predetermined patterns using stencil, printing or lithographic techniques.
Claim 4
Dependent Claim 36 words
The method of claim 1 wherein said art work is printed with a half tone pattern of non-fluorescent inks over said fluorescent colorants at a sufficient pattern density to mute the brilliancy of the fluorescent colorants.
Claim 5
Dependent Claim 19 words
The method of claim 2 wherein said fluorescent colorants are pigmented colorants and are applied with silk screen stencils.
Claim 6
Dependent Claim 27 words
The method of claim 2 including the steps of hand detailing said fine art by the application of a colorant without the use of a printing aid.
Claim 7
Dependent Claim 22 words
The method of claim 3 wherein preselected fluorescent colorants are applied in different proportions and to different areas than said non-fluorescent colorants.
