The below labels may be the same size and printed on the same material, but they contain a different number of digits, and thus have different scanning distances.įor additional help in determining the x-dimension, scanning distance, or correct number of digits for your application, don’t hesitate to contact The Label Experts. To give you an example of how different requirements might affect a label’s design, refer to the sample below. On barcodes, even dashes count as digits.īy plugging the x-dimension (chosen based off scanning distance), the calculated quiet zone, and number of digits into our formula, we can select the proper label size for your application. This is straight forward, more digits=longer barcode= larger label. The last step is to identify the number of digits you’ll be using in your barcode. As a rule of thumb, for a 1D barcode you should aim for a quiet zone 10x larger than the x-dimension (on each border). Quiet zone is the blank space around the barcode that is required for a scanner to read the barcode.
Once a material and x-dimension are selected, we have to calculate how much quiet zone the label needs to scan. The below chart compares the required x-dimension for each scanning distance, per material. The material you choose to print on also makes a difference in scanning distance (retro-reflective material has a farther scanning distance per inch). A larger x-dimension will allow your barcode to scan from farther away (to increase scanning distance it’s necessary to increase the x-dimension). The x-dimension, also commonly referred to as the mil size, is the size of the smallest bar on the barcode. DataMatrix X-Dimension The X dimension is measured in Mils, 1 Mil 1/1000 Inch. The scanning distance of your barcode is determined by its x-dimension. The X-dimension is the width of the smallest element in a DataMatrix bar code. To determine what size label will be most cost effective (without compromising functionality), both metrics have to be taken into consideration. Your desired scanning distance and the number of digits in your barcode are both key factors in determining the necessary warehouse label size.
BARCODE X DIMENSION HOW TO
*This only applies to IDAutomation barcode fonts designed to print at 12 points on 203 DPI printers such as Code 39, Code 128 or Universal Barcode Fonts.Warehouse Label Size – How to Choose Your Barcode Use the following chart to set the X Dimensions that create barcodes of the same width on 203 dpi and higher resolution printers: Printer dots A larger x-dimension will allow your barcode to scan. To create the most accurate sizes on printers with different resolutions, set the X dimension (or font point size when using a barcode font) to increments that are a multiple of the size of a dot on the lowest resolution printer. The x-dimension, also commonly referred to as the mil size, is the size of the smallest bar on the barcode. If this were not done, barcodes on the low-resolution printers would not be accurate. Barcodes and scanners have different X dimensions, so they must be matched.
In the barcode products, the barcode component will round down the measurement given to the nearest pixel and create the entire barcode from that number of pixels. X dimension is the measure of the narrowest bar in a barcode. Note that the white space on either side of. In this case, the bar height should never be truncated below the minimum required height for an 80 magnification barcode symbol. Therefore, 10 MILS or 0.026 CM should equal 2 dots on a 203 DPI printer. The smallest recommended barcode size for an EAN-13 barcode is 80 of standard size (approx. A minimum allowable magnification of 75 (X-dimension 0.25mm) applies only to on-demand (e.g. This is because at 203 dpi, the size of each dot in the printer is in increments of 5 mils or.
In addition, changing the X dimension when printing to low-resolution thermal printers may not actually have any effect. Because the barcode is created from the X dimension, different sized barcodes are sometimes created on printers with different resolutions. In the event that a value does not match up exactly with the printer, the component will calculate to the nearest possible X dimension.
The NarrowBarWidth (X dimension) in the IDAutomation Barcode Image Generator, Barcode Label Software and Barcode Components can only be adjusted to values the printer can support.
