For barcode printing, everyone is probably not too strange. Every day we brought food and daily necessities from the supermarket to the cash register. The cashier swept the item packaging bag with a guy of the same size and shape as the hair dryer, and only heard a "di", the price Appears on the computer. It has improved the speed and accuracy of manual accounting in the past, and has improved the modern business environment in terms of efficiency, risk, and cost. This is the application of barcode printers in shopping malls and supermarkets.
Barcode printing goes with you
In today's commerce and trade industry, such as apparel, electrical appliances and other department stores, all products with time limits or shelf life are related to its related records, such as name, model / series, ex-factory date, backlog period, etc. Different commodities may be distributed to different warehouses and managed by different personnel. In order to carry out unified and timely sales planning, a “printer†must be placed on the commodities through a barcode printer in order to facilitate inquiries and calls on the computer. It can be said that the bar code will be the identification card of all social goods.
Not only that, but in the past, the industrial manufacturing field, which attributed the focus of costs to the production process, gradually realized the impact of logistics informatization on the overall cost. According to statistics, China's logistics costs account for about 70% of the price difference between commodity purchases and sales. From the book, it can be seen that logistics costs account for 40% of the total commodity price. Then, it is urgent to reduce costs from the logistics link and speed up the development of logistics informatization. This move means collecting, classifying, transmitting, identifying, and inquiring about the information generated in the logistics process. Barcode printers are all inseparable.
It can be seen that bar code printing technology has been widely used in major industries such as commerce, production, circulation, and public facilities, which is beyond doubt. The question is, will the bar code printing, like ordinary printers, gradually penetrate into the field of our ordinary consumers as the demand expands? Let us first look at its technical principles, and then determine whether it may be applied to our daily lives.
Barcode printing origin and related technology
In 1949, American engineer Woodland invented the bar code printing technology based on the principle that different line widths obtained different recognition results, and applied for a patent in 1952.
Simply put, bar code printing technology mainly includes bar code printers, bar code scanners, label words and other components. This technology is composed of a set of parallel lines with different widths, black and white, and a combination of symbols in a specific format and spacing. Such symbols can achieve the purpose of dialogue between people and computers. The specific identification process is: when the light beam is emitted from the light emitter of the scanner and shines on the barcode, the photodetector responds according to the light intensity reflected from the barcode on the beam. When there is a blank space between two black lines, the reflected light intensity, the detector outputs a large current; when scanning into the black line, the reflected light is weak, the detector outputs a small current, and according to the width of the black line In response, it changes into current signals of different sizes with the change of the brightness of the bar code, which is amplified and sent to the decoder. Translate the signal into data through the decoder, perform local inspection and display, and send it to the computer for data processing. We know that computers use binary calculations, so the wide black lines in our barcodes are compiled into 1, the thin black lines are compiled into 0, and then converted into numbers or arrays from 0 to 9 through logic.
Based on this principle of reflected light recognition, we can also analyze the advantages and disadvantages of bar code printing technology:
First of all, the decoder is to identify the strength of the reflected photocurrent to 0 and 1. Then there are higher requirements for the color matching of the printing ink, whether the coloring density is uniform, and the color saturation. In addition, the color cast of ink is also worth noting in bar code printing.
The second is the requirement of the corresponding bearing. The bearer usually refers to the carrier of the barcode, such as packaging bags, membership cards, etc. When reading barcodes, the scanning light source is incident at a 45-degree angle, and the reflected light collection angle is 15 degrees. When the reflected light exceeds 15 degrees, the reflected light signal cannot be collected, which is equivalent to the black effect. Therefore, in order to meet the characteristics of barcode scanning, the substrate must have good light scattering characteristics, and no specular reflection can occur. Therefore, the white matter, opacity and gloss of the paper have a certain influence on the barcode recognition.
Finally, the print quality of the barcode, such as whether it is clear or flat, directly affects the compiler's recognition.
In fact, when the bar code printer was just born, due to the limitations of computer technology and some other factors (such as consumer trust in it), it did not grow very quickly. It was the American railway industry and General Motors Corporation. Be the first to introduce this technology. It was only in the mid-1970s that the widespread use of computer equipment and the bold attempts of large shopping malls made the bar code printing technology come alive. Until today, bar code printing technology has appeared in every corner of the industrial and commercial industries, mainly with famous brands such as Zebra in the United States, CAB in Germany, and ARGOX in Taiwan. So is it possible for the bar code printer, the identifier of the commodity, to hook up with the lives of our ordinary families?
Barcode technology is at your doorstep
Barcode technology has arrived at your doorstep, and this is not "admonishment." The Chengdu Water Supply Company claimed a few months ago: "The stainless steel file number plate hung on the water meter in the urban area of ​​Chengdu will gradually withdraw from the historical stage, and replaced by a bar code file number plate with a paste method." The important sign of water meter settlement is also an important basis for relevant staff to confirm the table position. In the past, the installation of the stainless steel file number plate hanging on the straight pipe section in front of the water meter was cumbersome and easy to lose, and the production cost was as high as one or two yuan each. If you use bar code technology, you only need to scan with a scanner, you can quickly and accurately record the number and store it in the computer. Not only the relevant staff, but even our own users only need to click the mouse beside the computer to grasp the usage of tap water.
We know that the advantages of bar code technology are mainly integration, real-time and collaborative management. Then, with the development of digitalization, combined with the application of barcode technology, computers and the Internet are no longer a single entertainment function for home users. Just as bar code technology is applied to the real-time monitoring and query of water meters, most residential communities will organize more household electronic devices such as electricity meters, gas meters and digital TVs in bar code technology to organize information into computers in the near future. It allows property managers and users to easily understand relevant information and communicate in a timely manner.
To create demand for products, we have every reason to believe that barcode technology will also be integrated into the lives of ordinary families like computers and printers.
