The Wheel Editor

The wheel editor is where we tell iStamp how a printwheel is configured, and what exactly is mounted to it. In iStamp's main window, click on the Wheel button. This opens the wheel editor application (the wheel editor can also be run from the Windows Start menu shortcut). At the top of the wheel editor window you'll see the selected wheel file, and buttons to open, save, and close a wheel file. Below, the wheel editor window is divided into two parts. On the left side of the window you'll see tabs for Wheel Info, and Character Positions which define the wheel. On the right side of the window you'll see tabs for Font List and Font Characters. These define the Logical Fonts for the selected wheel.

Wheel Info

Click the Wheel Info tab to see the wheel configuration. The wheel is given a unique wheel number, which appears in iStamp's Wheel selection drop-down list. The wheel may also be given a name for your convenience. The Row Configuration table defines the actual shape of the wheel, and how the characters are arranged.

The relevant parameters in the Row Configuration table are...
Row - This tells iStamp how many rows of characters can be mounted to this wheel. In this case, it's a wheel with four rows.
Chrs - This is the actual number of characters mounted to each row. Each row can accommodate up to 36 characters.
Theta - This is the angle of each row measured from the center-line of the print-wheel.

Other settings are covered in more detail in the Wheel File Appendix.

Character Positions

Click the Character Positions tab. This shows a table defining what physical character are mounted at each individual position on the wheel.

The relevant parameters are...
Pos - This is the physical position on the printwheel for each character. For more information on position numbering, see the page on Print-Wheel Maintenance.
Ch - This is a label for the character mounted at that location. It's generally the same as the physical character, but need not be.
Or - The Orientation of the character, or how the character is mounted to the wheel. This affects how the character is actually stamped. Possible orientations are H (horizontal), V (vertical down the spine), and U (vertical up the spine).
Wid - The width of the character, in thousandths of an inch.
Description - This can be used to make a note about the character, especially if it's an unusual one that can't be identified by the label. For instance: "soccer ball icon".
Pos, Ch, and Wid are required. The Or, and Description fields are optional.

Font List

The font list displays what Logical Fonts are defined for this print-wheel. Buttons are available for Adding, Deleting, or Copying the highlighted font. Attributes for the highlighted font are listed in a table below. These are:

Font number - For internal use only.
Name - This is the name of the font that appears in iStamp's Font drop-down list.
Orientation - The Orientation of the character, or how the character is mounted to the wheel. Possible orientations are H (horizontal), V (vertical down the spine), and U (vertical up the spine).
Height - The height of the font in Thousandths of an inch. Height is generally measured on an uppercase M (em height).
Offset - This is a Y offset for the font, in thousandths of an inch. This can be used to adjust the vertical position of the font with respect to other fonts.
Char Gap - The space between each character in a word, in thousandths of an inch. This can be used to condense or expand a font to your taste.
Kern - These two values determine how far to kern characters, in thousandths of an inch. For more information on this subject, see the page on Advanced Kerning.
Rev - The Y offset used when the print-wheel is reversed.

Font Characters

The font characters tab displays a table listing all of the attributes for each character in the font highlighted in the font list above. These are:

Ky - This is the key you press on your keyboard, or the character that appears in a job file that is used to invoke this logical font character. Note that the Key can be different from the physical font character, AND it might be different than the character that is displayed in iStamp. The Key simply tells iStamp WHAT to stamp.
S - This allows you to use a shifted or alternate key to double the number of available keys on the keyboard. For instance, the key for one character might be the lowercase a to stamp a lowercase a. The key for another character might be Alt-a to stamp a lowercase a with an acute accent - รก.
Pos The printwheel position that will be stamped when this character is invoked.
Wid The width of the logical font character. This isn't necessarily the same as the width of the physical character.
Ch - The character displayed in iStamp's text editor window when this character is invoked. Note that the Key, Ch, and the physical character on the print-wheel might all be different.
KM - See the page on Advanced Kerning for more information.
KL - See the page on Advanced Kerning for more information.
XO - This can be used to adjust the horizontal postion of the character.
YO- Used to adjust the vertical position of the character.
XOR- Used to adjust the horizontal position of the character when the print-wheel is reversed. For more information, see the page on Reversing the Print-Wheel.
YOR - Used to adjust the vertical position of the character when the print-wheel is reversed. For more information, see the page on Reversing the Print-Wheel.
Dep - Used to adjust the stamp depth of each character. This is especially useful when stamping very small characters, like punctuation, which might punch through the product material.
Dwl - Used to adjust the amount of time that the character remains pressed into the material during stamping.
Tag - This is a label that can be used instead of the Key to invoke this character.
