To efficiently process a job like this, use rotation tools or array functions in your design software. These functions allow images or graphics to be placed at a specific rotation or “degree” around a circle. For a clock, each hour should be engraved at 30-degree intervals, while the minutes should be engraved every half of a degree.
Another option is to download a vector clipart of a clock and modify it as needed. Once the file is complete, the laser effectively and accurately engraves that image into the desired material.
