The soljet Roland printer can print on variouse types of materials.
But the naterial colour has to be white. The printing image quality changes with the material quality.
How does it work.
Some materials are pure white
that can print image same as the image you can see on screen. But the Artwork must be in good quality. If the media is on pure white and Artwork has low resolution and low quality images that also give a bad output.
Some materials are off-white
That material can print on the machine but you can't get the image quality as you seen as on the screen. What happen is when the material is off white the image get small darkness and it looks like bad quality.
Some materials are very shiny (Glossy look)
These material can give us a good quality. When the material is on pure white and glossy you can get the best quality ever if the Artwork is in good condition (Good resolution).
