Kindly refer to the 3D viewer in order to get a better idea about the placement and size of your design. Try not to place logos or text too close to the edges. Ensure that your design and/or uploaded images are of a high resolution. If it looks pixelated on your screen when you zoom in, the resolution isn’t high enough. Try not to use dark colors on top of each other. Place the serial number position and starting number, and our designer will complete the sequence accordingly. Please mark the perforation on top of the design using the "Perforation-line" element which can be found in the Clipart and Images gallery under the category "Design Tools". The perforation line should be vertical and it should be placed at least 3 cm away from the edges of the design.
