Abstract: A controlling apparatus, comprising: at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: obtain a file comprising an image to be marked on a surface; analyze the image to be marked on the surface and determine one or more continuous areas of the image having the same fill color and on colors in the image; obtain information on the quality and thickness of the surface of the object to be marked; determine order in which the areas of the image with different colors are to be marked; determine on the basis of the determined and obtained information parameters for a laser marking apparatus separately for each area of the image with different colors; and store determined parameters in a marking file.

Abstract: Apparatus related to marking a metal surface are provided. The solution includes a bed for an object including a metal surface, the bed including a total marking area; a cover forming an airtight space over the bed; one or more laser marking units capable of directing a laser beam onto the metal surface located within a unit marking area, wherein the unit marking area is smaller than the total marking area. In the proposed solution control data including information on the marking of a pattern on the metal surface is received; the focus, bandwidth and movement of the one or more laser marking units is controlled on the basis of the control data to produce the pattern defined in the control data on the metal surface.

Abstract: Apparatus related to marking a metal surface are provided. The solution comprises receiving (600) control data comprising information on the marking of a pattern on the metal surface; controlling (604, 606) a temperature control unit and a gas unit to produce a temperature and atmosphere in space under a cover on the basis of the control data; controlling (602) the focus and bandwidth of a laser marking unit on the basis of the control data to produce the pattern defined in the control data on the metal surface; and controlling (608) a coating unit on the basis of the control data to produce a coating on the metal surface.
