Laser marking has been widely used in various industries, in the traditional printing industry, laser marking machine has also been used in Logo printing, jeans printing, customized image printing and other applications, compared with traditional silk screen printing and heat transfer film printing technology, what is the pros and cons of laser marking?
Compare with silk screen printing and heat transfer film printing, laser marking is more flexible, as traditional printing technology needs to follow complicated steps: coat screen, burn screen, rinse out image, tape up screen, set up screen, print logo and cure ink, each step can’t go wrong, whereas laser marking is much easier, just 2 steps to print a new pattern: edit logo in CAD software and print in the laser control software, this greatly reduced the error rate.
No consumable and less maintenance
Laser Marking no consumables，but silkscreen requires the use of inks.
In silk screen printing or heat transfer film printing, operators need to check whether the screen was blocked, is there cross-section on the printed graphics, is the screen surface clean, is the working environment clean and dust-free.
There is no special requirement when operating lasers.
Better working environment
Though laser marking produces smoke, dust and dazzling light, exhaust fans can be used to pull out smoke and dust, protective enclosure can be mounted to protect operators from laser radiation, this improves the working environment.
Ink produces unpleasant smell when mixing and printing, the smelly cannot be effectively removed
Laser marking machine is easy to use, as long as operators can use CAD software and laser control software.
While the silk screen requires operators to be very careful, they need to mix ink to deploy the desired color, when printing, they need to check whether the screen was blocked, is there cross-section on the printed graphics, is the screen surface clean, is the working environment clean and dust-free.
Laser cannot print a variety of colors; laser marking uses high-energy beam that causes the surface of the material chemical reaction at high temperatures, the printed color is the color of the oxide and normally it is in black, white or yellow.
Whereas silk screen and heat transfer film printing can print almost all colors, as it deploys color by mixing inks, all colors could be made by mixing 6 basic ink colors.
