Unique Pixel Stretch Sig:
1. New Document (350x120) Fill it with Black.
2. Next you are going to want to grab a render. I Suggest looking through NoLimits Render Gallery, Located
Here. I’ll Be Using Iron Man. So this Tutorial will be based around making that render match the background, change some things to match your render.
3. This is what my Sig looks like so far, pretty basic.

4. Now, you are going to want to duplicate that render layer (Ctrl+J), and size it down to a reasonable size, and center it on the signature. Like This.
5. Now duplicate that Render layer, and go “Filter > Distort > Ripple” (Size – Medium | Amount: 530%)
6. Now, place that layer below your main center render layer. And drop the opacity down to 40%.

7. Now drop the opacity of your Large Render layer, down to 40% as well.

8. Click on your main Render layer, and grab Single Column Marquee Tool, go to about the middle of your render and click down. (It should make a one-pixel selection from the top to the bottom.) Now right+click on the inside of that 1 pixel selection, and go “Layer Via Copy” (This will copy that one pixel selection to a new layer.

9. Now click on that 1 Pixel layer, and press “Ctrl+T” Now drag the edges to each end of the signature. Also, set the Blending mode to “Screen”

(Make sure the Pixel Layer, is underneath all your Render layers)
10. Grab you’re bottom layer (should be plain black) and go “Filter > Render > clouds” and then go, “Filter > Render > Difference Clouds”
11. now, go “Filter > Brush Strokes > Accented Edges” (Edge Width: 1 | Edge Brightness: 50 | Smoothness: 15)

12. Now Press “Ctrl+U” to bring up Hue/Saturation. And use these settings.

13. Now make a new layer (Above all your other layers) fill it with black, and set the blending mode to “Screen”
14. Now go to the Layer styles, and use these settings:
Inner Shadow: Default Settings.
Gradient Overlay:
Pattern Overlay:
Stroke: 
Now you just need to add some Text. And your final result should look something like this!

This tutorial was long, and somewhat confusing at times, if you have any questions please feel free to ask, and I will explain as best I can.
