Large Format Substrates: Rigid vs. Roll
The main difference between printed materials is how they are fed to the printer.
The two main options are either roll-fed or a rigid printing system. Of course, whether or not you are familiar with large format printing, the utilization of rolled flexible material is common in smaller format printing techniques. Similar to those applications, the different flexible substrate chosen will still have to reflect the type of imagery, size, and ink choice. These substrates are typically limited to papers, or flexible plastic composites, which can be sold and shipped on a roll.
Alternately, large format printer applications can also produce rigid products with an extremely large variety of different options. This process is known as direct to substrate printing.
Again, certain printers will only be able to accommodate certain thicknesses of rigid printable substrates. But, the rigid substrate should still have a surface texture that supports the full color gamut of the printed image in order to capture the full resolution of the images.
