Precautions for photo engraving
Step 1: Find the right photos
Laser engraving machine image, the first must be the need for high resolution, high quality. The resolution of the image must be high, and the size of the image should be appropriate, can not cause the image too fuzzy by enlarging the image, reduce the resolution of the image. An image suitable for engraving needs to have a certain amount of contrast and exposure. Therefore, if you have a large area of solid color content, the result will not be good, so the photo with more detail will definitely be easier to carve good results.
Step 2: Edit your photos
As long as you are able to use the corresponding all kinds of photo editing software, cut into appropriate carving area the size of the size, then the background, because the object of engraving machine carving only focus, will be converted to grayscale images, increase brightness and reduce contrast, also can choose to change the color mode images, then need to sharpen the image, the edge of the image object can be more clear, The lines are also more pronounced. Especially if you want to sculpt a portrait or other pet image with high detail, sharpen the glasses, lips, hair and other details as much as possible. Once you've done this, you've edited the photo and you're ready to print it.
Step 3: Do a test before engraving
Even minor changes to your photo settings can have a big impact on your completed project. For example, changing the tonal contrast between dark and light areas on a photo will make the gradient look sharper or softer. Always scan the photo with color when carving. Color will have some other information different from black and white colors. Additional information from the color can give you more information. These specific operations require the engraver to learn a number of advanced photo editing steps that translate into sculpting of varying intensity and detail levels.
Of course, different materials should use different laser power, if your engraving needs to be darker, you can increase the power or slow down the speed. If the engraving needs to be brighter, reduce the power a bit or increase the speed. In summary, the best results for photo engraving come from using high contrast images. Not all photos or materials are the same, and you may need to adjust the image to make it more suitable for laser engraving.
