Barcodes are widely used around the world in many contexts. In stores, UPC barcodes are pre-printed on most items other than fresh produce from a grocery store. This speeds up processing at check-outs and helps track items and also reduces instances of shoplifting involving price tag swapping, although shoplifters can now print their own barcodes.[20] Barcodes that encode a book's ISBN are also widely pre-printed on books, journals and other printed materials. In addition, retail chain membership cards use barcodes to identify customers, allowing for customized marketing and greater understanding of individual consumer shopping patterns. At the point of sale, shoppers can get product discounts or special marketing offers through the address or e-mail address provided at registration.

In return, we ask you to implement a back-link with the text "TEC-IT Barcode Generator" on your web-site. Back-linking to www.tec-it.com is highly appreciated, the use of TEC-IT logos is optional.
Many people use Illustrator for designing book covers, blisters or packaging. In most cases barcodes have to be added to the artwork.There are two ways to create barcodes in Illustrator: You can use an integrated solution, like a barcode extension or plug-inor you can use an external barcode generator to create the code and then import it into Illustrator. In this tutorial we look at the different options for adding a barcode to your artwork.
The Softmatic barcode extensions for InDesign, Illustrator and Photoshop are available on the Adobe Exchange and from the Softmatic online store. Adobe Illustrator - Using a barcode generatorA stand-alone barcode generator is preferable if you use an older Creative Suite version of AI (CS3, CS4, CS5, CS6 etc.) that doesn't support the plug-in.Our recommendation here is Softmatic BarcodePlus V5, download here (macOS 10.15 or higher, pre 10.15: here, Windows 10 here). The app creates all common retail barcodes, like EAN, UPC or ISBN and will save codes as EPS/PDF and in various raster formats. In addition BarcodePlus V5 supports a wide varietybarcodes for warehousing, pharmaceuticals and 2D symbologies like QR, Aztec or PDF417.Barcodes in Adobe Illustrator - Best PracticesWhen working with barcodes in Illustrator, please consider the following best practices:Before creating the barcode, talk to your print shop about the requirements with regard to bar width reduction.Reasonable values are: Offset printing: 1-2%
Laser printing: 1-2%
Thermo-, thermotransfer printing: 0%
Inkjet printing: Plain paper - 5%, Inkjet paper - 1-2%
Pad printing: up to 10%
The Softmatic generators and extensions create barcodes in pure black (CMYK: 0 0 0 100). Per default, Illustrator will convert pure blacks into so called "Rich Blacks" (typically CMYK: 50 50 50 100) for export. This can cause issues with misaglined printing plates, resulting in bars that look fuzzy or have a color halo. For best results, set Preferences > Appearance of Black to "Output all blacks accurately".
Place the barcode artwork on a separate layer. Lock the layer against accidental changes. A separate layer can also be useful to create a barcode template, for example when you have QR codes with URLs or email addresses that don't change often.
Leave space of at least 5mm around the barcode. This space is off limits for other artwork.
Never modify the actual barcode within Illustrator. Don't scale it, don't stretch it, don't change the fill or stroke, don't change the text. If the size is not right, discard the code and create a new one.
If at all possible, make a test scan of the barcode before going into production. A simple CCD hand held barcode scanner will not cost more than about $50. That's a good investment if you have to create barcodes regularly. Alternatively, use a barcode app with your smartphone, see next section.
For detailed information about the placement rules for Bookland / ISBN codes on book covers, see here.
Verifying and scanning barcodes We recommend test scanning or verifying barcodes before going into production. Current smartphones will be able to detect and scan barcodes with the built-in camera.
Some barcode types have options for the generator. This example sets the eclevel flag to control the error correction level of the QR Code. To know which options are available for a barcode type, use the BWIPP docs as reference:
Generate accurate barcodes with the greatest design freedom without sacrificing security. The barcodes are real vector graphics (no bitmap images) and they are protected from unwanted edits or changes. The barcodes can only be modified in the plug-in palette.
