Selecting this option allows you to add a letterhead to your printouts of the diamond and colored stone weight estimators, the pearl grader, and the diamond cut grading modules. After you have filled in your data you should select the Fonts button.  This will give you an opportunity to select a font that is on your computer.  The default font is Times New Roman (a serif font).  Arial (a sans serif font) is also a good choice. Changing the font style, size, or color will have no effect.

No Header: If you do not want a header, set the Blank Lines to about 12 and then click the Clear button (See Below).

Blank Lines: If you want to use your existing letterhead, you will need to set the Blank Lines box to approximately 12 or so (depending on how far down the page your letterhead goes), then click the Clear button.  This inserts blank lines which will lower the printing of the program data creating enough room for your letterhead.
