Each supported substrate type has its own characteristics. For optimum print quality, the printer changes the way it prints on each different substrate type. For example, some may need more ink and some may require higher temperatures for drying and curing. So the printer must be given a description of the requirements of each substrate type. This description is called a substrate preset. The printer is supplied with substrate presets for some specific substrate types, and also with presets for some generic types. Each generic preset comes in three variations: with 100%, 150%, and 250% ink density.
As it is inconvenient to scroll through a list of all substrate types available, your printer contains substrate presets for only the most commonly used substrate types.
For your convenience, substrate settings from many substrate vendors have been collected at http://www.hp.com/go/LX850/solutions/ and http://www.hp.com/go/LX820/solutions/. You can check substrate availability using the Media Finder application that you will find there.
To install a new substrate preset that you have downloaded, go to the HP Internal Print Server and select Substrate > Presets management.
