Your text is declared, but never used. It don't appears anywhere as it 
don't exist at all in the scene.

You can use the object pigment. This is a block pattern that take an 
object and two pigments/patterns.
Used like this, the texture, if any, of the object is meaningless.

pigment {
   object {
     text1
     color White // outside of the text
     color Red // inside of text, or colour of the letters
     }
   }

You need to properly rotate and translate your text object. It start at 
<0,0,0> and successive letters go to the right and above the X axis. The 
thickness goes toward +Z.
It may be easier to start with :

plane{-z,0
  pigment {
   object {
     text1
     color White // outside of the text
     color Red // inside of text, or colour of the letters
     }
   translate -0.1*z
  //Make the front of the text go in front of the plane
  // otherwise, you may get coincident surface like artefacts
   }
  rotate Your_Rotation
}

Another way would be to place your object on the plane :
union{
  plane{-z,0 }
  object{text1 translate -0.0001*z}
  pigment{rgb 1}
}
