Hello,
You want white or non color text on a black box, right?
If this is what you want....
Select the non color for the color of the text.
Now if you do this and it isnt working try rebuilding your preferences this can cause this to not to work at times.
Close pagemaker.
PC look for the rsrc folder in the Pagemaker folder.
Open the rsrc folder then open the usenglsh folder.
Right click and choose to delete the following items:
PM65.cnf, PM65filt.cnf, PM65ppd.cnf, and pstyles. (change the version number depending on the version you are using.
Mac look in the Pagemaker folder and put in the trash the following items:
pm65filt, pm65ppd and printer styles.
Look in the system folder for the preference folder. In the preference folder remove the adobe pagemaker preference.
Now restart pagemaker and try this.
Also check in the printer setting and make sure "inverted" is either selected or not depending on the printer selection for the correct printing.
If this doesnt help give me a little more info.
Good luck.
