In an effort to streamline our DVD and CD creation process, Lulu has recently implemented the use of barcodes. These barcodes are very small (1.5” x 0.5” or 3.81 x 1.27 cm) and will appear on various sections of the CD and DVD finished product. The implementation of these barcodes is strictly for the purpose of keeping the various pieces of your project together during production, and is not for the purpose of assisting in retail sales.
The location of the barcode varies.
* the barcode appears on the back of the insert in the upper right-hand corner, 0.125” (or .32 cm) from the top and side.
* the barcode also appears on the tray card (back of the case) aligned to the bottom right-hand corner.
