We use media name Board as a conventional term to identify all products that can be printed on the flat surfaces of the materials with some thickness.
Nowadays you can print on nearly everything. Plenty of materials can be used as media. Save traditional paper, one can put an image on canvas, metal, acrylic, glass, MDF or wood to name some of them. Hefest Digital to Solid service allows you to make fine previews of the prints as they were printed on specific materials to show how the final result looks like.
Rich media editor in the Management Panel allows to configure web previews really close to the printed originals. You can use different textures, thickness and other board parameters to adjust your previews to be really very close to the final printing original.
You want to receive a job file ready for printing. It means that you should take into account such things like bleed, board edge colour, type of canvas wrapping on the stretcher, width of planks for wooden boards, etc. These settings can be done with Digital to Solid service to deliver you a job file which you can smoothly print without delay.
