How to mark QR code?

how to mark QR code?There is a button in the marking software ,it can directly enter the QR code, different types of QR code can be set by modifying the font. The black part mark white QR code easy to read, can add frame and then fill, it is easy to read; the white part can mark black QR code, do not need to fill. In conclusion contrast and light factors is to determine whether QR code can be read out.

Line and 2D codes, like serial numbers, are already used in most industries, such as (e.g. the automotive industry, medical technology, or electronics industry), in order to make products or individual parts traceable. The codes (mostly data matrix or bar codes) contain information regarding the parts properties, production data, batch numbers and much more. Such component marking must be readable in a simple manner and partially also electronically and have a lasting durability. Here, laser marking proves to be a flexible and universal tool for a wide variety of materials, shapes and sizes as well as the processing of dynamic and changing data. Parts are laser-marked at the highest speed and absolute precision, while wear is minimal.

Suitable materials for laser processing
Components, parts or products of all types of metals e.g.:

stainless steel, alloyed steels
aluminum, anodized aluminum
titanium, titanium alloys
brass
copper, other precious metals
coated metals
Components, parts or products of plastics e.g.:

PA, PC, PE, PET, PMMA
silicone or many other plastics
Depending on requirements, metals and plastics can either be laser marked or laser engraved.

Part labeling based on specifications:
In contrast to the design of parts in creative industries, codes and serial numbers often have to be applied to the products in accordance with customer specifications or legal requirements in industry (e.g., the automotive and supply industry, the electronics industry, medical technology, etc.).

The marking of the parts thus does not increase the profit. This means that the marking must be as cost-efficient as possible. Here, laser marking also offers unbeatable advantages, since no setup costs or elaborate and expensive preparatory work are required. No matter whether 1 or 1000 parts – the cost per laser marking is always at the same low level.
