Custom covers are designed to replace the studio covers supplied with DVDs. Normally these are in plastic outer sleeves and can simply be removed and replaced. Where WB have used the dreaded cardboard snapper cases or the large CD style case alternative cases need to be obtained.
Multi-cases can be used to substantially reduce the amount of shelf space required, especially when the studio packs 6 disks into 6 seperate cases. Cases for up to 10 disks at a time can be obtained which are only up to 32mm wide.
The tutorials section gives basic info to photoshop newcomers on how to scan, modify and print images, create backgrounds, use layers...
These are my personally designed covers, mostly shelf saving designs for tv series.
These are the basic box sizes, templates fonts, logos, and links to other sites you'll need when designing covers.
