This function is particularly handy when engraving images on dark materials like black stone or rubber, as well as layered materials like mirrors, and transparent or translucent acrylic. It allows you to invert the color of your image for a better engraving result.
Currently, bitmaps can be divided into colored, grayscale, and black-and-white bitmaps according to the color. The color of the three types of bitmaps can be inverted. Depending on the kind of image you're working with, the function may work a bit differently. Please remember that this function is not applicable to the translucent or transparent background of the image.
After importing a bitmap image, select it to reveal the editing panel on the right, where you can find the "invert color" switch.
For black & white images, the invert function changes black pixels to white and white pixels to black.
Since laser can only engrave three colors: black, white and gray, all color images are converted into grayscale images before being inverted.
Some pictures will have transparent or semi-transparent backgrounds, so the transparent parts of the picture will not be inverted, and will still remain transparent. And the opaque parts of the picture will be inverted.
Similarly, with a grayscale image, light-colored pixels become dark, and dark-colored pixels become light when inverted.
You might wonder why it doesn't change the color depth Settings when using Invert color. This is because the inverted color is a fixed formula for calculating colors. In XCS software, if you want to adjust the shade of the inverse color, here is a tip:
Reverse the color of the picture first, and then adjust the gray value.
If the engraved color is darker than the material, we don't recommend using the Invert function. Conversely, if the engraved color is lighter than the material, the Invert function can actually improve your results.
