902 results about "Color printing" patented technology

Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color. For example, red and green yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be considered "tertiary."

Digitally printed products and process

A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.; producing a test print by applying a decorative pattern to the baseweb by a digital ink jet printer and making an optional software-driven image-related adjustment in the standard to color match the standard to the test print image; and when the adjusted standard image displayed on the screen is acceptable, passing an image-related output to the digital ink jet printer for printing a decorative print color-matched to the accepted onscreen standard.

Signal synchronization tapping plate for ink jet printer and signal transmission method

The invention discloses a signal synchronization tapping plate for an ink jet printer and a signal transmission method. The tapping plate is characterized in that one end is provided with a receiving port for receiving a detection signal, and the other end is provided with an output port connecting nozzle control boards for outputting a detection signal; the interior of the tapping plate is provided with an FPGA which divides the received detection signal into at least two detection signals with the same channel at the same time in a tapping manner; the output port transmits the detection signals with the same channel after tapping to at least two nozzle control boards in a synchronous and parallel manner, so as to control the nozzle to print. The tapping plate divides the detection signal into multi-channel signals in a tapping manner, and can be connected with the plurality of nozzle control boards at the same time, thereby controlling more nozzles to print. The different mode of arrangement of the nozzles can increase the printing width, printing speed and printing resolution or achieve the multi-color printing. Meanwhile, the nozzle control boards are used for receiving the signals synchronously, thereby avoiding printing lag of a certain nozzle caused by signal asynchronization, and protecting printing quality from being affected.
