DETAILED DESCRIPTION

As illustrated in the example of FIG. 1, the present disclosure provides an illuminable image 10. In one implementation, the illuminable image includes a substrate 12, a transparent light directing channel 14 printed on the substrate, and an image 16 printed over at least a portion of the printed transparent light directing channel. As such, light from a light source can be directed through the light channel to illuminate the image. In one implementation, the light source is an active light source (such as an LED) and, in another implementation, the light source is a passive light source (such as ambient light).

FIGS. 2A, 2B, 3A, 3B schematically illustrate one example of forming an illuminable image 100. In one example, illuminable image 100 is formed on a substrate 110. Substrate 110 may include, for example, sheet material, such as paper, including photographic paper, card stock, transparencies, Mylar, and the like, as well as fabric, packaging material, and other printable media.

As illustrated in the example of FIGS. 2A and 2B, illuminable image 100 includes a light directing channel 120, with light directing channel 120 formed on substrate 110. More specifically, light directing channel 120 is formed on a surface 112 of substrate 110.

In one example, light directing channel 120 is formed by printing on substrate 110 including, more specifically, printing on surface 112 of substrate 110. In one implementation, light directing channel 120 is transparent and is formed by depositing one layer (i.e., a single layer) or more than one layer (i.e., multiple layers) of transparent ink 102 on substrate 110. As such, light directing channel 120 provides a light channel on substrate 110 for directing light to and/or through an image, as described below.

Transparent ink 102 is free of dyes and pigments, and may be deposited by, for example, an inkjet printer, an offset printer such as a liquid electrophotographic (LEP) printer, a laser printer, a three-dimensional (3-D) printer or other type of printer. In one example, the transparent ink is deposited by an LEP printer where an electrically-charged liquid ink is dried and applied to a substrate via a thermal blanket. In another example, the transparent ink is deposited by a 3-D printer where drops of fluid are ejected onto a layer (or layers) of a build material, whereby energy, such as heat, is applied to the layer (or layers) of build material such that the build material is fused or sintered. The build material may comprise a powder-based build material including wet and/or dry powder-based materials, particulate materials, and/or granular materials.

In one example, as illustrated in FIG. 2B, a hole or opening 114 is formed through or provided in substrate 110. In one implementation, light directing channel 120 is formed over hole or opening 114 such that hole or opening 114 is temporarily filled with a fill material 116 during forming of light directing channel 120.

As illustrated in the example of FIGS. 3A and 3B, an image 150 is formed on substrate 110, including, more specifically, on surface 112 of substrate 110, and over light directing channel 120. More specifically, at least a portion of image 150 is formed over light directing channel 120. Image 150 may include characters, symbols, and/or other graphics formed on substrate 110 and over light directing channel 120. Image 150 may be formed of various colors, including black or grayscale colors.

In one example, image 150 is formed by printing on substrate 110 and over light directing channel 120. More specifically, in one implementation, image 150 is a visible image and formed by depositing visible ink on substrate 110 and over light directing channel 120. Visible ink includes dyes or pigments, and may be deposited by, for example, an inkjet printer, an offset printer such as a liquid electrophotographic (LEP) printer, a laser printer, a 3-D printer or other type of printer.

In one example, image 150 is formed such that a portion, segment or area (or portions, segments or areas) 122 of light directing channel 120 is (are) exposed through image 150. With image 150 printed over light directing channel 120, and with portions, segments or areas 122 of light directing channel 120 exposed through image 150, image 150 may be illuminated, as described below.

In one implementation, as illustrated in the example of FIG. 3B, fill material 116 is removed from opening 114, and a light source 160, such as an LED light, as an example of an active light source, is inserted in or communicated with opening 114. As such, light from light source 160 is directed through light directing channel 120. Accordingly, with light directing channel 120 provided under image 150, including, more specifically, under at least a portion of image 150, and with portions, segments or areas 122 of light directing channel 120 exposed through image 150, light from light source 160 illuminates image 150.

In another implementation, light source 160 may be embedded in substrate 110 (for example, before forming of light directing channel 120 on substrate 110). In another implementation, light source 160 may be positioned on surface 112 of substrate 110 (for example, at an end of light directing channel 120). In some implementations, light source 160 may be cycled (for example, on and off) to control or vary illumination of image 150.

Although illustrated as being rectangular in shape, light directing channel 120 may be of other shapes and/or sizes. In addition, although illustrated as including a single light directing channel 120, illuminable image 100 may include any number of light directing channels 120, including one (i.e., a single) light directing channel 120 or more than one (i.e., multiple) light directing channel 120.

Although illustrated as being circular in shape, opening 114 may be of other shapes and/or sizes. In addition, substrate 110 may include one such hole or opening or more than one such hole or opening.

Although illustrated as being irregular in shape, image 150 may be of other shapes, sizes, configurations and/or arrangements or combination of shapes, sizes, configurations and/or arrangements.

As such, light gathering channel 230 provides a light channel on substrate 210 for gathering light (for example, ambient light or direct light), light transferring channel 240 provides a light channel on substrate 210 for transferring gathered light from light gathering channel 230 to light directing channel 220, and light directing channel 220 provides a light channel on substrate 210 for directing light to and/or through an image, as described below.

As illustrated in the example of FIGS. 5A and 5B, an image 250 is formed on substrate 210, including, more specifically, on surface 212 of substrate 210, and over light directing channel 220. More specifically, at least a portion of image 250 is formed over light directing channel 220. Image 250 may include characters, symbols, and/or other graphics formed on substrate 210 and over light directing channel 220. Image 250 may be formed of various colors, including black or grayscale colors.

More specifically, in one implementation, and similar to image 150, image 250 is a visible image and formed by depositing visible ink on substrate 210 and over light directing channel 220 (including over a portion of light transferring channel 240).

In one example, and similar to image 150, image 250 is formed such that a portion, segment or area (or portions, segments or areas) 222 of light directing channel 220 is (are) exposed through image 250. With image 250 printed over light directing channel 220, and with portions, segments or areas 222 of light directing channel 220 exposed through image 250, image 250 may be illuminated, as described below.

In one implementation, ambient light 260, as an example of a light source, is gathered by light gathering channel 230. As such, gathered ambient light is transferred from light gathering channel 230 to light directing channel 220 by light transferring channel 240 and directed through light directing channel 220. Accordingly, with light directing channel 220 provided under image 250, including, more specifically, under at least a portion of image 250, and with portions, segments or areas 222 of light directing channel 220 exposed through image 250, ambient light 260 illuminates image 250.

Although illustrated as being rectangular in shape, light directing channel 220, light gathering channel 230, and/or light transferring channel 240 each may be of other shapes and/or sizes. In addition, although illustrated as being a single light directing channel, light directing channel 220 may include multiple light directing channels. Furthermore, although illustrated as including two light gathering channels 230, illuminable image 200 may include any number of light gathering channels 230, including one (i.e., a single) light gathering channel 230 or more than one (i.e., multiple) light gathering channel 230. In addition, although illustrated as including four light transferring channels 240 communicated with light directing channel 220, illuminable image 200 may include any number of light transferring channels 240 communicated with light directing channel 220.

Although illustrated as being irregular in shape, image 250 may be of other shapes, sizes, configurations and/or arrangements or combination of shapes, sizes, configurations and/or arrangements.
