The Strati resulted from the 3D Printed Car Design Challenge, conducted using crowd-sourcing technologies by Local Motors, which is based in Phoenix, Arizona. The company believes it is at the forefront of the 3D Industrial Revolution and describes itself as a free online and physical workspace that enables people to turn their vehicle innovations into reality and rewards them for their contribution. The key issues discussed in the brief for the design challenge were as follows.

  • Hi TeXnicians, PDF showing CMYK color instead of Black percentages in the shading area since this is single color book. – Rajesh N Mar 2 at 11:23
  • We checked color preview, Adobe acrobat Pro-->Advanced-->Print Production-->Output Preview; Cyan-9%,Magenta-6%,Yellow-7%,Black-0% which decreased gradient value upto CMYK 0%. But we need gradient value CMYK:0,0,0,10 to CMYK:0,0,0,0(single color layout) – Rajesh N Mar 2 at 11:27
