How to Make a Barcode in Photoshop
Open Photoshop. Go to "File" and click "New." Make the size settings whatever you like. Then go to the Layer panel and click on the "New Layer" icon.
Go to the Toolbar, then the "Shapes" tool, and select "Line." Hold down the shift key and draw one short line.
Now go to "Filter" and select "Noise," and click "Add Noise." Make the "Amount" setting 110.
Go to "Edit," then "Transform," and click on "Scale." Then drag up the middle handle to raise the height to get the bars part of your barcode.
Go to the Toolbar, and under the bars, type in a series of random numbers to serve as your barcode numbers.
