Recently, some friends have encountered problems related to bar code printing. The other party has been printing barcodes for more than 20 years. It has been safe and sound. There have been few serious problems in the past, and most of them have been solved. The scanners in their hands are also capable of reading barcodes. It is quite high. If it is not for a large customer to purchase a barcode detector, it will not be considered to spend more than 20,000 Hong Kong dollars to purchase. The customer also said that if he did not purchase, he would buy it on his behalf and deduct it from the purchase price. My friend thinks that since the barcode has proved to be readable, I have to report it to prove what A, B, and C grades are achieved.
After listening to a friend complaining about bitter water, I had to answer this question: the quality of bar code printing has not been valued. The bar code detector of American brand does not meet the ISO/IEC 15426-1 international bar code detector standard and ISO/IEC 15416-1 printing quality. Standards, so the past printers said that the qualifications, the customer said that the situation of non-conformity occurred, when the problem occurred, everyone seems to find no solution, had to pay or deduct some of the money. Of course, the printer is extremely reluctant or willing to wait for this in the future.
The bar code is just like everyone thinks. Just looking for a scanner to scan and read it will prove the world is popular?
The answer is of course no. First of all, barcode scanners are not only one type, barcode size, scanning distance, environmental factors used in the field, aperture wavelengths are different, plus barcode system, coding rules are not known to everyone, simply said, the same string of numbers, many A bar code system can also be done. The light is made by using a scanner, and it will not be found at all. When it is delivered, it is discovered that it has been hateful. Foreign well-known customers have encountered many similar problems in the past, so they decided to make this move. At each delivery, they requested a bar code test report to support them. Avoid unnecessary disputes, or a friend may ask: tried to test with other brands of detectors, but the customer does not recognize the test results. Yes, this situation has really happened. It is understood that there are two reasons.
1. the instrument has new and old but no regular correction, so there are different test results.
2. Two of the two sets of equipment or one of them does not comply with international standards (ISO/IEC15426 -1 and ISO /IEC 15416-1), and the difference is understandable.
In fact, if the instruments used by both parties are in accordance with ISO/IEC-15426-1, even if they are different brands, the results should be consistent. It is a pity that the US and German brands have a bad test result, which leads to the misunderstanding or loss of confidence of most people. It should be squarely and disorderly. Anyway, most printers do not know enough about bar code standards. If they do not cooperate with printing technology training, they only purchase. The standard equipment will only be unable to catch up, adding troubles. There are some real professional consultants in the workshop, not only provide reliable barcode detectors, but also have a complete set of technical training courses. The problems can be easily solved. Finding the wrong supplier is not only a waste of money, but also worthy of use. Please be good before purchasing. Think twice.
How to judge suppliers and equipment to be eligible
To verify that the barcode reaches the A, B, and C levels, seven items need to be verified, including symbol contrast, modulation ratio, and coded degree. May ask the supplier, if the other party proves that everything is correct, can answer the question, I believe that there are not many people, the equipment should be accompanied by a signed confirmation to reach the target certificate, if only a copy of the ordinary computer print, I believe any People can copy the same, don't believe it. The most important thing is that you can print out the inspection report with ISO/IEC 15416-1, which is the correct product. It is simply not the evidence that the general supplier can come up with. In the age of developed information, the ability to distinguish between right and wrong must also be improved.
