Laser marking technology has more than 20 years of history, has been steadily occupied the market had been part of the traditional marking techniques such as EDM, corrosion, mechanical scribing and inkjet printing rule. Laser marking can gradually replace the ink-jet printing of the main reasons for this are several aspects anodized laser coders, one ink-jet printing is used, paints and solvents may cause environmental problems, on the other hand a lasting inkjet printing is also problematic, because the majority of such markers can be used to remove the solvent. Under deduction ratio, it is possible to laser marking on a variety of materials to produce a clear, durable mark. Jun crown laser research and development products are: Dongguan laser marking machine, fiber laser marking machine, the semiconductor side pump laser marking machine, CO2 laser marking machine, laser and other industrial equipment. Currently the most commonly used one-dimensional code, book bag food packaging, medicine boxes can see, we have no such a concept is that regardless of the back cover of the book, how bright leather laser coders food box or medicine box pattern color while the one-dimensional bar code data lines are black laser coders, the bottom is generally white or pale-based, is not it? Or you can now get your side of the one-dimensional look at the code. Here, I tell you, the color is very important, that bar code scanning equipment required for color, while natural junior high school physics book book, elementary school said, and black and white is the color of the biggest. As long as there is color, barcode scanners to read out the exact contents of one-dimensional code out. In the previous section, we discuss the one-dimensional code, and the two-dimensional code is the same, the two-dimensional code scanning equipment also to produce color, correct and complete in order to read its contents. This is why the background is white two-dimensional code, its design is black causes. Now we return to the problem of laser marking machine play barcode scanners can identify the one-dimensional bar code and two-dimensional barcodes, as long as we can make out of the bar code laser coders play a larger and background color can be laser code machines, such as playing a dark gray or white or light-colored barcode material inside, or vice versa, in a black or dark-colored, low color, white or light-colored pattern play to be able to play a valid barcode. Company products include: fiber laser marking machines, semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine, laser inkjet printer and other industrial laser equipment.
