Yes. We print in full color at 900DPI (that's photo quality) using the latest digital printing technology. We can also print brilliant, opaque (non-see-thru) white.
There are no extra costs for the number of colors you want to use.
Here's a color swatch printed on holographic material.
The swatch shows different CMYK colors printed over the holographic material to give each color a metallic effect. We can print white behind the color to remove the metallic effect and make it a 'normal', flat color.
