20150246551 | METHOD FOR ADJUSTING COLOR TEMPERATURE OF SURFACE LIGHT-EMITTING ILLUMINATION DEVICE AND PRINTING DEVICE FOR PRODUCING SURFACE LIGHT-EMITTING ILLUMINATION DEVICE - A surface-emitting illuminating device includes a light guide plate, a light source for emitting light to the interior of the light guide plate, and a light reflection plate and/or a light diffusion plate. The color temperature of the light-emitting face of the prepared surface-emitting illuminating device is measured. When the measured color temperature is not a required color temperature, ink for coloring the light reflection plate and/or light diffuser plate is selected. The selected ink is used to subject the light reflection plate and/or light diffuser plate to a coloring printing by an inkjet printer. The color temperature of the light-emitting face of the surface-emitting illuminating device is measured. Until the measured color temperature of the light-emitting face of the surface-emitting illuminating device is within an allowable range, the color printing of the light reflection plate and/or light diffuser plate is repeatedly corrected. | 09-03-2015 |
20150054186 | LIGHT-GUIDE-PLATE CREATION METHOD AND DEVICE - Provided is a light guide plate for a liquid crystal screen display apparatus providing a favorable visual effect. The printing data of a light reflection pattern stored in a computer is transferred to an inkjet printer to allow the inkjet printer to subject a substantially-rectangular printing face surrounded by upper and lower and left and right edges of a light guide plate to a reflective printing for diffusing light emitted from a light source into the interior of the light guide plate. The printing data for performing the reflective printing is prepared so that a printing density is increased from the edges in the four directions corresponding to the edges in the four directions of the light guide plate toward one or more high density setting points set in front of the respective opposed edges. The reflective printing is performed using white ink including titanium oxide. | 02-26-2015 |
20150049349 | GRADATION-PATTERN CREATION PROGRAM - A gradation pattern preparation program by which a complicated gradation pattern can be prepared easily, wherein a computer is caused to function as: a vertical and horizontal printing density control line generation means for displaying, on a campus face, vertical and horizontal printing density control lines in a net-like manner, a vertical cross section line generation means for displaying a cross section image of the selected vertical printing density control line as a vertical cross section line on a vertical cross section line display screen, a horizontal cross section line generation means for displaying a cross section image of the selected horizontal printing density control line as a horizontal cross section line on a horizontal cross section line display screen, a printing density control point generation means for displaying, on the respective vertical and horizontal cross section lines, printing density control points for editing the respective vertical and horizontal cross section lines, and a printing density control point shift means for changing, in accordance with the shift of the printing density control points, heights to reference lines of the respective vertical and horizontal cross section lines. | 02-19-2015 |
