Barcodes and the importance of their verification before printing

Barcodes are an efficient and accurate way to quickly identify products. Verifying their reading before printing them is crucial to avoid having to repeat printing runs (in the best of cases) and/or avoiding having to withdraw products from the market due to reading problems.

Flexographic barcode printing follows a process similar to printing other types of images and text. However, there are some special considerations to take into account before and during your print:

Design: must comply with international standards, using specialized software to design and generate it. You must take into account the color of the substrate, the color of the ink and the contrast that is achieved between the two. For example, if the barcode is to be printed on white material, black ink can be used, as the contrast between black and white is high and the code will be easily readable.

• Selection of inks and materials: The inks used to print them must have good adhesion and resistance to abrasion, water and sun.

• Reading verification: this is probably the most important step, you should do it before and after printing to make sure everything is in order.

It is important to keep in mind that, regardless of the color chosen to print the barcode, the quality of the ink and the substrate is essential to maintain its legibility over time.
