Over the years I have seen scripts in all varieties.
From the very expensive and tidy glossy color paper print, to a few hastily scratched words on the back of a paper tissue.
The basis for a good and succesful reading is a good script. And that counts both for the content and the packaging.
When supplying scripts, please send them as a formatted PDF that will print uniformly on all printers. Excel scripts are the worst, since they tend to display differently between computer platforms and programs. And valuable time is wasted trying to copy/paste and reformat the words into a readable document.
