Laser application is now nearly everywhere in our daily life. The production date & pattern on the food and beverage products, the keypad on the mobile phone, keyboard, remote control and many more......These are all laser engraved. Among those, laser engraved photo is a novel way of photo which intrigues many people, especially young people. Now let’s talk about how to laser engrave a photo.
Firstly, in order to have the amazing engraving effect on the photo, choose high definition photo is a MUST. The selected photo is also expected to be in sharp contrast in brightness and darkness. Secondly, use a professional image editing software to edit the photo. This requires to change the photo into indexed color and then into grey. Sometimes the background color also needs to be removed so that the figure can be outstanding. Thirdly, change the file into BMP file and send it to the laser engraving machine. Then the laser engraving machine will “create” the beautiful engraved photo.
Different materials will have different engraving effect, for different materials have different absorption rate of the laser source light in laser engraving machine. In photo laser engraving machine, the common laser source is CO2 laser tube. Even for the same photo, the engraving outcome would be quite different in black plastic and transparent acrylic. Therefore, before engraving, it is suggested to test every kind of material in order to adjust the software and other parameters accordingly.
As mentioned before, photo laser engraving machine is often supported by CO2 laser tube. CO2 laser tube is easy to crack when it becomes overheating. In this case, a
laser water chiller would be very ideal. S&A Teyu CW-5000 and CW-5200
