var emptyProduct = {
    surfaces: [
        {
            width: 720,
            height: 504,
            proofImage: {
                fileFormat: "PNG",
                mockupEnabled: false

        }]
};
```
 
## Properties
 
### Optional cropSafetyLineName
 
cropSafetyLineName: string

The name of a safety line which proof images are cropped to; if there is no safety line with the given name, proof images are not cropped. The default value is `"bleed"`.
