The laser marking machine is equipped with a laser generator, controlled by computer software, combined with the principles of optical lens focusing, deflection, etc., so that the laser is projected onto the surface of the product. According to the graphics and parameters set by the software, the controllable laser makes the surface of the product Discoloration or vaporization, forming a permanent mark. It is called laser marking machine, laser engraving machine, laser machine, etc. Don't make too many statements here.
Bitmap images (bitmaps), also known as bitmap images or raster images, are composed of individual points called pixels (picture elements). To put it plainly, pictures taken by our digital cameras, mobile phones, and pictures cut on computer screens can be called bitmaps. We can simply draw the equal sign as: bitmaps are pictures, photos.
How to type a bitmap
Most of the most common applications of laser marking machines are vector graphics. The vector diagram is simpler. It is a drawing composed of closed curves such as points and lines drawn with drawing software such as CDR and CAD. It is not distorted with the enlargement or reduction of the graphics, and has nothing to do with the resolution. Only this kind of graphics, we can use the laser marking machine Set the filling parameters and marking parameters above. It can control better marking effect. The laser marking machine marking bitmap, all the marking software currently on the market, when we import the bitmap into the software, the software will be divided into similar resolution points according to its own calculation function to complete the laser marking. The principle is the same as black and white TV imaging. The current bitmap laser marking is also unable to complete color marking. After the color picture is imported into the software, the software will convert to a black and white mode bitmap, automatically distribute the laser light energy according to the black and white proportion of the picture, and complete 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 to print 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 area of the material we want to print, set the picture DPI to a fixed 300 (dpi), as shown in the picture:
Here we must know that the laser is the color of the surface of the vaporized material. If it is not dark, or the color of the material under the surface material is not exposed, we must first determine the characteristics of the material to be made, such as the black metal business card I want to type now. , The surface is black paint, after the laser is finished, it is the silver shiny metal color below, we want to create the image of Shouxing, it should be reversed to vaporize other areas, leaving a portrait part, so at this time check (reverse) option.
Grayscale and expansion buttons mainly adjust the black and white contrast of the picture. Here we are going to adjust it according to the difference in the background color of the selected picture and the parameter debugging test.
(Dot), check the dots, the typed pictures are dot-like collection imaging, there will be no reflective discoloration, but the resolution will decline.
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. 35% is tested first. The color is not clear enough and then the power is increased. The frequency can be 30 low frequency.
The laser marking machine prints a bitmap, which is a great test of the operator's familiarity with the software and the control of the material characteristics. If we want to engage in printing photos on the customer's mobile phone, because there is no sample material for debugging, it needs to be formed at one time. The challenge is also 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 engage in laser marking machines to print photos for customers' mobile phone cases, etc. must understand this. It's still very difficult. I hope these answers can help everyone.
