 Photo engraving on stainless steel with the Watson laser marking machine. Prepare the selected photo. To do this, you need to reduce or increase the photo for our workpiece. Convert the image to grayscale view. Adjust the contrast. Set a resolution of at least 150 dpi and save. Open the photo in EasyCAD 2. Adjust the size of the image to the size of the workpiece on which you will engrave. Center the image and set the convenient parameters. Specific radiation parameters will depend on the power of your marker. In this example, we use a marker with a 20 watt power. Select the minimum power for the lightest areas and the maximum for the darkest. Start engraving. You can achieve different shades by balancing the parameters of power, speed, frequency and number of steps. We will be glad to help you in choosing the equipment you need.
