Abstract: In one example in accordance with the present disclosure a printer cartridge and memory device containing a representation of a compressed multi-dimensional color table is described. The color table includes at least one low dimensional portion of the multi-dimensional color table storing color transformation information at a first resolution and a number of remaining portions of the multi-dimensional color table storing color transformation information at a second resolution. In the color table, the first resolution is greater than the second resolution and the at least one compressed multi-dimensional color table is to generate a high resolution uncompressed multi-dimensional color table the high resolution being at least as great as the first resolution.

Abstract: Authenticating a consumable product based on a remaining life value includes determining whether an identifier stored in memory of a consumable product is listed in a device history and concluding that the consumable product is not authentic if the device is determined to have used the consumable product previously based on the device history and a current remaining life value associated with the consumable product indicates less use than a recorded remaining life value for the consumable product associated with the identifier in the device history.

Abstract: Example implementations relate to secure messages for IoT devices. For example, a system for secure messages for IoT devices may include an IoT device coupled to a network including a plurality of web services. The IoT device may store a service certificate for each of the plurality of web services, generate a secure message for a web service among the plurality of web services using the stored service certificate for the web service, and send the secure message to the web service without first establishing a connection between the IoT device and the web service.

Abstract: A printer cartridge includes a memory device and at least one compressed color table stored on the memory device. A compressed color table includes a losslessly compressed neutral axis, a number of nodes that correspond to seed color table nodes and a number of delta nodes that correspond to a number of delta tables. The number of delta tables indicate differences between interpolated color table nodes and corresponding actual color table nodes.

Abstract: In an example implementation, an authentication system includes a printer having a controller and a memory. The authentication system also includes an authentication algorithm stored in the memory and executable on the controller to issue a cryptographic timing challenge, and to authenticate a print supply cartridge when the cartridge provides a challenge response corresponding to an expected response within an expected time window.

Abstract: A transform wrapper is stored on a memory device and the memory device may be included in a printer cartridge. The transform wrapper may dynamically build a transform map for a printer based on metadata stored at the memory device. The metadata may indicate at least one of a type of depositing material, transform map, print media and printer.
