This enables high productivity in the manufacturing of printed materials that involve the use of special inks and color inks. [Solution] A method for manufacturing security printed material includes generating print data containing multiple print data elements corresponding to multiple pixels from first and second image data that reproduce an image containing a first image and an image containing a second image, respectively, wherein a first group of pixels consisting of a part of the pixels displays the first image, and each of the print data elements corresponding to the above part of the pixels includes a gray value of either subtractive color mixing or additive color mixing; a second group of pixels consisting of another part of the pixels displays the second image, and each of the print data elements corresponding to the above other part of the pixels includes a gray value of either subtractive color mixing or additive color mixing; the first image data includes a plurality of first image data elements, each containing a gray value of additive color mixing; and the second image data includes a plurality of second image data elements, each containing a gray value of subtractive color mixing.

The application relates to the technical field of color display devices, and discloses a color display structure controlled by a motor array, which comprises a display panel, a plurality of groups of color block rotating structures are equidistantly distributed on the upper surface of the display panel, and a motor is fixedly installed at the bottom of the display panel, wherein the number of the motor is the same as that of the color block rotating structures; the color block rotating structure comprises a base, the base is rotationally connected with a limiting panel, a color sheet is fixedly installed on the upper surface of the base, a connecting gear sleeve is fixedly installed at the bottom of the base, and the connecting gear sleeve is fixedly connected with the output end of the motor through the display panel. Compared with the display technology of the common additive color principle on the market, the application has the advantages of low energy consumption, creativity and artistic performance; compared with the printing advertisement of the subtractive color principle on the market, the application has the advantages of dynamic display, real-time updating, interactivity, a new artistic creative expression approach and simple maintenance.

A method for controlling a lighting fixture for emitting light having a target color having an subtractive color mixing system, the method comprising: receiving target information indicative of, such as defining, the target color, calculating a target control setpoint for each subtractive filter within the plurality of subtractive filters based on the target information and calibration data, the calibration data for a plurality of sets of calibration control setpoints being indicative of emitted color, and controlling each of the subtractive filters in accordance with each calculated target control setpoint for each of the subtractive filters.
