Roland VS540-6C driver version 10.2A or newer, supports CMYKOG+Silver which allows printing of White and Silver with the CMYKOG print mode
The resolutions containing white and/or silver determine the layer order.
As the print mode and resolution combinations are a bit confusing, here a list of some typical examples:
Working combinations for white and silver and color would be (Silver and White active under the page setup tab):
Print mode CMYKOG+Silver
Resolution 1440x720 White+Color+Silver
