This is a shot in the dark...
If you are trying to make white copy on a black background try this:
Create a new layer.
•Select all
•Go to your color picker
•Choose black
•Fill with black
•Choose tour Type tool
•Go to your color picker
•Choose white
•Change to the font you want
•Begin to type what you want
•This will create a new type layer
You can add effects, move the text, edit if not rasterized, change leading, alignment, etc.
If this is completely off base, sorry.
Another thought:
If you want bars of black behine the white type instead it being solid, try this:
Type out what you want, fix the type, font, leading, etc. in black. When the type if perfect determine how many lines you have of the copy.On a separate layer draw a rectangle exactly as long as the first line. Now duplicate that layer as many times are there are lines of copy. Take the first layer of the black rectangle and line it up perfectly with the first line of copy. Go to the last line of copy and take the last rectangle layer and line it up perfectly. If you want varients in length as to show the differnce in each line, transfrom each one. When doing so only change the width so it will match the line. Next go to the alignment/distribute tool. Click on all layers with a black rectangle. Now click on distribute space vertically. This will spread them evenly and hopefully where each line is. You may have to adjust.
Another way is to rasterize a duplicate type layer, keeping the original type layer. Be sure to change the type to white before rasterizing! Hide the original type layer. Then divide each line of the rasterized type. Make black rectangles to the desired size, each on its own layer. Then align each line of type to each rectangle. Add a folder to each duo layer of white type and a black rectangle. Select all layers in the layer palette and hit distribute vertically. Each line of type will be aligned and ditrbuted perfectly.
