Abstract: Examples of the present disclosure relate to a three-dimensional printing preparation controller. The controller comprises a processor, a data storage coupled to the processor and an instruction set to cooperate with the processor and the data storage. The instruction set detects a request to mix a first and a second material in a specific proportion, the first and the second material having respectively first and second characteristics; the first characteristics differing from the second characteristics, validates the request by comparing the specific proportion and the first and second characteristics with validated proportions and validated characteristics and mixes the first and second materials in the specific proportion if the request is validated to correspond to validated proportions and validated characteristics.

Abstract: A method is described in which a printed image which has been printed by a printer based on a printing template is repaired. A damaged area of the printed image is identified and a reprinting segment on the printed image is determined such as to overlap the identified damaged area. With the printer a layer of printing fluid is printed over the damaged image and a correction printing template is printed. The correction printing template includes a segment of the printing template that corresponds to the reprinting segment of the printed image.
