Code Reading and Verification

Code Reading and Verification

1d- Linear (1d) the data is within the lines and the width.

2d- marked directly onto product or label to be tracked through the product process. It needs to be determined the code can be read and therefore verified after marking. The solution needs to be able to run at a fast and accurate speed. As a 2D code carries information in both X and Y axes this is machine readable code. The reading and verification solution will decode and

In compliance lead industries, these codes need to be reliably recorded and inspected to meet standards, especially ISO. The systems are pre-programmed with parameters in which the code must read- this can be added to and adapted. Quality parameters will be detailed by the customer.

Perceptor Software will take the encoded data and decrypt to revealing the information input within the database.

Important aspects of the system and printing needs to consider:

Background: Busy backgrounds with transparent codes as an overlay can course false rejects

Skew: Ensure that the characteristics of the printed mark is not in any way effected by the print speed/ linear speed of the product passing by the printer

Lighting: reflective lighting can distort codes through the lenses- ensure lighting and angles are accurate ensures a reliable system.

Contrast: the repeatability of the contrast levels between foreground (characters) and background not necessarily the actual level of contrast.

Stretch and compression: The physical mark will often be printed whilst the product is being transported past the marking head. The speed of the transportation past the marking head can vary. It is essential that the marking system is implemented in such a way that allows for accuracy of the characters
