    Abstract: Examples of a method of operating an additive manufacturing system, a three-dimensional (3D) printing system and a non-transitory machine-readable medium are described. In an example, a build material is supplied to a print region of an additive manufacturing system. A temperature distribution, corresponding to a pattern, of at least a surface of the build material is generated. An image of the pattern is captured using a thermal sensor. Image data representative of the image of the pattern is compared with data representative of an expected position of the pattern. On the basis of the comparing, difference data indicative of a difference between a position of the thermal sensor during capture of the image and an expected position of the thermal sensor associated with the expected position of the pattern is generated. Operation of the additive manufacturing system is controlled at least in dependence on the difference data.

    Abstract: A printer and a method of processing an image (1) to be printed with a printer which has a printing unit arranged to produce a printout from image-representing print data of the image, and a processing unit for processing image-representing input data of the image so as to generate the image-representing print data. The processing unit is arranged for separating the image into a line detail sub-image (20) containing edge and line details, and an area detail sub-image (25) containing area details, performing a first printing mode processing pipeline on the line detail sub-image and performing a second, different printing mode processing pipeline on the area detail sub-image, and generating multi-layer print mask data, wherein at least one print mask data layer is usable to print the line detail sub-image in at least one line detail print pass, and the remaining, i.e. at least one of the print mask data layers being used to print the area detail sub-image in at least one area detail print pass to produce an image (50) which has optimized image quality.
