Yes the Optilux Enhanced supposedly has the addition of 5% silver shimmer. I made my own version, regular Optilux with 5% Wilflex silver shimmer printed through 150 Smartmesh, one hit on black poly garment. Sorry for the crappy pic. The one on the left is my enhanced.
We have switched from the Wilflex Imagebright to Optilux and are very happy. It print well on a number of different fabrics from cotton to 100% poly!
