UPC Color and Sizing Information
In order for a UPC barcode to be scanned, it must adhere to UPC barcode color and dimensional guidelines. Due to the varying type of scanners and scanning environments, the colors used for both the background and bars of a UPC barcode are very important. In addition, there are also minimum and maximum sizes (also known as magnification) for UPC barcodes. GS1 is the global identification standards organization. GS1 publishes the 488 page GS1 General Specifications.
UPC Barcode Color Requirements
In order for a barcode symbol to be recognized by a scanner, there must be an adequate contrast between the dark bars and the light spaces. Since most barcode scanners operate with a laser which identifies “red” as white, it is extremely important that appropriate bar and space colors are determined.
UPC Barcode Size Requirements
In order for a UPC symbol to be scannable, it must be generated within the acceptable size range. When the UPC guidelines were originally published, there was a stated “standard” size UPC barcode called 100% magnification. The overall dimensions of a 100% UPC are 1.46″ x 1.02″. The sizing range for UPC magnifications is between 80-200%. The table below provides the specific dimensions for each UPC magnification.
