Abstract: A method, preferably a computer-implemented method, for synthesizing m-bit print data and for providing the data to a printer, the method including: a) inputting object-based data of at least one image in the form of a page description language into a raster image processor having at least one system-on-chip comprising a plurality of processors; b) converting the object-based data into n-bit pixel data of each color channel of a first target color space with a predefined image resolution by providing the object-based data to some or to all of the plurality of processors and processing the data in parallel by means of the processors; c) converting the n-bit pixel data of each color channel into m-bit print data of each color channel of a second target color space by means of at least one dithering algorithm and storing or buffering the m-bit print data in an output memory; d) providing the m-bit print data to the printer and printing on at least one print medium by means of the printer.
Abstract: Printing system including at least a first and a second print head in which the printing system is configured in such a way that the first and second print heads can be adjusted actuator-based with respect to a printing medium by positioning and orienting using an adjustment actuator. The printing system includes at least one adjustment actuator less than the number of print heads provided in the printing system, and an auxiliary device is provided in the printing system such that with the aid thereof an operative connection of the at least one adjustment actuator with the first print head can be released and/or created, and an operative connection with the second print head can be created and/or released, preferably also actuator-based or in a pneumatic and actuator-based manner, and particularly preferably automatically.

Abstract: A spray coating apparatus is provided, wherein a nozzle is arranged to traverse a fabric in one direction whilst simultaneously spraying and oscillating in another direction. The fabric is spray coated with a first pass having a spray zone having uneven distribution in the direction of oscillation, and particularly with a greater density of fluid coverage toward the centre of the spray zone than an edge. The nozzle forming a second and subsequent pass that is off-set from the first and each subsequent pass respectively. The second and each subsequent pass being arranged to overlap with a portion of the previous pass, thereby providing an improved distribution of the spray coating. Moreover, because the spray coating is incremental, the method is easily adaptable to integrate with an ink jet printing process.
