A numerical controller includes: a model holding unit that holds a machine model, the machine model being a model that simulates deformation of a mechanical structure accompanying motion of the mechanical structure in axial directions and representing an error amount as an amount of displacement of a tool; a machining error estimation unit that estimates an error direction and the error amount in the error direction on the basis of axis data that is data on drive of a drive mechanism and the machine model, the error direction being a direction in which displacement of the tool occurs among the axial directions; and a correction amount arithmetic unit that selects one or more of the axes subject to correction, and performs arithmetic to find a correction amount used for correction of a command to be output to the drive mechanism for the axis selected.

A method for making a thermal transfer type multicolor printing. An ink ribbon is set over a platen roller with a printing paper being interposed between them, the ink ribbon having at predetermined intervals a plurality of ink zones each carrying one of heat-dissolving inks of different colors. Then, one of the ink zones is positioned at a printing position on the platen roller, the one ink zone being of a predetermined color. A thermal head is placed at the printing position against the positioned one ink zone, and drived for transferring a first dot line of the ink of the one ink zone to the printing paper so that one picture component, for the predetermined color, of a picture to be printed is reproduced by the use of the ink of the one ink zone. Thereafter, the printing paper and the ink ribbon are advanced for a subsequent printing when unreproduced portion of the picture component exists. The procedures of the driving of the thermal head and the advancing of the printing paper and the ink ribbon are repeated until the whole picture component for the predetermined color is reproduced on the printing paper. Then, the procedures after the setting of the ink ribbon are repeated with respect to the other ink zones of different colors for reproducing the remaining picture components of the different colors on the printing paper, so that a multicolor picture is reproduced on the printing paper.
