10. Does a wall printer need a flat surface that moves along the wall? Very flat walls are not required, our wall printers can print high quality images on uneven surfaces, but you need to ensure that the surface is a uniform curved surface and not a protruding surface.
How many ink channels does the DX7 printhead have? Can you print white and colour together? -- eight ink channels, can print CMYK+WWWWWW, but the white effect is not very visible. If printing on dark walls, it is best to configure a double-headed CMYKCMYK+WWWWWWWW.
