Readable, accurate barcodes and texts have never been so important in production. Quality deficiencies lead to inefficient processes and downtime, while unreadable barcodes can result in re-labeling, re-reading or even lengthy manual input of important information. We can help you identify the root causes of errors, which can save you valuable time and energy. Once the reason for the unreadable barcode is found, the problem can be remedied by simple preventive measures.
We provide the following code quality control services:
- Linear and 2D code control service
- Measurement of original symbols using a device that complies with ISO 15426-1/2
- Control report in digital format with parameters conforming to ISO 15415/15416
- Creating summary tables
- Identification of patterns with a unique identifier
Official expert opinion based on linear and 2D code control
- explanation of measurement parameters
- mapping out errors based on the checks carried out
Consultancy
Change suggestions regarding the quality of production and the data content of the code (the latter is only possible if the production process is known).
Who needs code control and when?
For the maker of the symbol: you can use the measurement information to control your production processes and to adjust your equipment and procedures accordingly.
For packaging designers: measurement/control feedback as to whether the size, positioning and color of the symbol will cause a problem at the point of use.
For the recipient of the product: reading problems can be reduced by timely code quality control in management and inventory control systems, and at the point of use.
It is the responsibility of the symbol’s creator (usually the manufacturer of the product) to guarantee that the symbol complies with the quality requirements.
When can we control a code?
I. In the design phase
II. In the special case of printing immediately after the symbol generation
III. After the product has been completed (on receipt of the finished product)
What does code quality control mean?
Code quality control: the technical process in which the extent of compliance with quality standards and readability at the point of use is checked for individual barcodes or 2D symbols. Control is based on standards.
Code quality control device: the control devoice is a precision measuring instrument designed to measure code quality. Its make-up and operation are based on standards. To ensure the accuracy of the measurements, the measuring devices should be regularly calibrated. The results of the measurements must be reproducible using the same device or a standard instrument.
What is code control good for and when do I need it?
- Barcodes and 2D codes carry data,
- Create a physical connection between the source system and the target system,
- In the event of an error, the communication chain is interrupted,
- Control helps to ensure readability,
- It confirms that the code reaches the quality level required for the application,
- It helps to control the production process to improve the symbol’s quality,
- It shows how the symbol should work in the target application,
- It allows the diagnosis of the imperfect results’ causes.
Our company, Vonalkód Rendszerház Kft., undertakes the quality control of various codes (1D, 2D, DPM) by means of technical devices, even in laboratory conditions.
CloseWhat does the readability of the code depend on?
The readability of the codes depends on the properties of the code reader used:
- Is the reader familiar with the coding algorithm for the symbol and is it activated?
- Which decoding software specialties are included in the reader (varies from manufacturer to manufacturer and from product to product)?
- What type of optical system does the reader have?
- What reading system does it have?
- What resolution are the optics tuned to?
- How much data has to be decoded?
The readability of the barcode depends on the characteristics of the code to be read:
- What surface was the code generated on?
- Which printing process was used?
- In which size was the code printed?
- In which quality was the code printed?
- How much data was decoded?
- The readability of the barcode depends on the characteristics of the symbol type
- What security levels are applies?
- How does it respond to distortions and errors in general?
