Preparing a photo for laser engraving requires several important steps to ensure the best results. First, choose a high-resolution image, ideally at least 300 DPI, to maintain clarity. If possible, select a black and white image or convert a color photo to grayscale, as this will provide better contrast and detail when engraved.

Next, use photo editing software to adjust the brightness and contrast, ensuring that the dark areas are prominent while light spots are minimized. This helps in emphasizing the features you want to engrave. You may also need to resize the image to match the dimensions of the engraving area.

After that, consider converting your image into a bitmap or using thresholding techniques to create a more defined outline. Some laser engraving machines require specific file formats, so save your edited image as a .BMP, .PNG, or vector graphic like .SVG or .AI, depending on the engraver’s requirements.

Lastly, run a test engraving on a similar material, if available. This allows you to see the quality of the engraving before executing the final job. By following these steps, you can prepare your photo effectively for laser engraving.
