How to print bitmap for uv laser diode marking machine
Aug 31 , 2021The laser marking machine is a kind of matching laser generator, controlled by computer software, with the principle of optical lens focusing and deflection, so that the laser is projected on the product surface, and the controllable laser makes the surface of the product according to the graphics files and parameters set by the software. Discoloration or vaporization, forming a permanent mark. It is called laser marking machine or laser engraving machine, laser machine and so on. I won't make too many statements here.
Bitmap images (bitmaps) are also called bitmap images or raster images, and are composed of single points called pixels (picture elements). To put it more popularly, photos taken by our digital cameras, mobile phones, and pictures cut from the computer screen can all be called bitmaps. We can simply draw the equal sign as: bitmaps are pictures and photos.

The most common application of laser marking machine is mostly to print vector graphics. A simpler vector diagram is to use CDR, CAD and other drawing software to draw a graph composed of closed curves such as points and lines. It is not enlarged or reduced with the graph, and has nothing to do with the resolution. Only this type of graph can be used in the laser marking machine. The filling parameters and marking parameters are set above. It can control better marking effect. For the laser marking machine to make bitmaps, all the current marking software on the market, when we import the bitmap into the software, the software will follow its own calculation function and disperse it into points of similar resolution to complete the laser marking. The principle is the same as that of black-and-white TV imaging. The current bitmap laser marking is also unable to complete color marking. When the color picture is imported into the software, the software will convert it into a bitmap in black and white mode, automatically distribute the laser light energy according to the proportion of black and white of the picture, and finish the dark and light laser laser on the surface of the material to form a black and white picture.
After popularizing the professional knowledge of laser marking machine printing photos, let's explain how to set up the software. Let's take the most commonly used golden orange software as an example: First open the software and import the picture, adjust the size of the picture according to the size of the material we want to print, set the picture DPI to a fixed 300 (dpi), as shown in the picture: Here we need to know that the laser is the color of the surface of the vaporized material, whether it forms a dark color, or the color of the material under the surface material is exposed, we must first determine the characteristics of the material to be made, such as the black metal business card I want to print now , The surface is black paint, and after the laser is finished, it will be the silver shiny metal color below. We want to create the image of the birthday star, which should be inverted to vaporize other areas, leaving the portrait part, so check the (invert) option at this time. The grayscale and expansion buttons mainly adjust the black and white contrast of the picture. Here we need to adjust it according to the background color drop of the selected picture and the parameter debugging test. (Dot), check the dots, and the typed pictures are collected in dots, and there will be no reflections and discoloration, but the resolution will be reduced. After setting the picture, the setting speed of the laser parameters on the right side of the software is generally about 1000, the power is turned on first, and 35% is tested first. If the color is not clear enough, increase the power, and use a low frequency of 30.
The laser marking machine prints bitmaps, which test the operator’s software familiarity and control of the material characteristics. If we want to print photos on the customer’s mobile phone, because there is no sample material for debugging, it needs to be formed at one time, which is very useful. The challenge is to master some image processing software, such as PS, etc. After all, the photos are square, and it is best to process them into a heart-shaped or other pattern to be attractive. Therefore, entrepreneurs who want to work on laser marking machines to print photos to customers' mobile phone cases, etc., must figure out this. It's still very difficult. Hope these answers can help you easily.
