Clear zone Please print the barcode plus an additional 2mm clear zone around it on a background with a constant reflectance.
Delivery Point Suffix Requirements For Access 70 CBC a minimum of 90% of the mailing items must contain a CBC with an accurate DPS. The remaining mailing items (up to 10%) may contain a CBC with a default DPS. Please note: that the above requirements for an accurate DPS have been suspended until further notice. However the requirement to have a CBC on 90% of the mailing items at Access 70 CBC applies. Printing the barcode Royal Mail can supply you with a Barcode font for common software applications that produce barcodes. Or, we can provide a list of third parties who can carry out barcode printing. If the Royal Mail font is not compatible with the Customers printing software they will need to purchase the font from their printer supplier. Position The exact positioning of the barcode is given below. In practice, it’s very straightforward to get the positioning right because we can provide the Customer with the relevant template to overlay on top of your sample barcode, see CBC template above. • On the front of your item. • At least 18mm from the bottom edge, and no more than 120mm from the bottom edge. • At least 15mm from the top edge. • At least 15mm from the right and left edges. Length The barcode must be a continuous string of characters, without gaps or space characters. Customers must set it at between 20 to 24 bars per 25.4mm.The characters must be equally spaced. The length of the barcode will vary depending on the number of characters in the Postcode.The minimum possible length is 35.31mm – for a five character Postcode at 24 bars per inch (per 25.4mm).The maximum is 54.37mm – for a seven character Postcode at 20 bars per inch (per 25.4mm). The barcode must appear:
Edges of the barcode These must be sharp and clearly defined.This helps eliminate misreading.
The range of sizes are:
Vertical alignment
The track element of the bars must be symmetrical to the centre line (C/L): Skew Each bar of the code should be perpendicular to the edge of your item as possible, and to other bars.The most that can be skewed each bar is 5° in either direction. Optical specification Please print the barcode so it contrasts with the underlying colour – for example black bars on a white background.There must be at least 30% difference in reflectance between the bars and the background. Print quality should be consistent throughout the code. Customers need to take into account the print process they’re using and the material onto which they are printing.
Overlay template
Royal Mail can provide you with simple overlays, which shows if you have the correct length and density of the barcode.
