There are thousands of different dieline layouts and there is always a chance that you cannot find the one you need in our list. Please contact us and provide some details about the missing layout. The more information you provide, the better. Vector graphics is the best, but raster, scans or even photos are OK, as well. We'll then consider adding the layout to our list, so you and other people can use it.
Please make sure that you can share that kind of data, as some of the dielines may be intellectual property. By sending layouts to us you confirm that there are no restrictions on processing and providing them on this site. Avoid sending files that you are not sure about.
