Part 1: The .EMB File (The “Source”)

The Analogy: Think of this like a Microsoft Word Document.

• What it does: It is the original working file. The software understands that “This is a letter ‘A'” and “This is a circle.”
• Resize Ability: Unlimited. You can resize an .EMB file by 50% or 200%, and the software will automatically recalculate the stitches to keep the logo looking perfect.
• Caveat: Physics still applies. If you shrink it too much, text may become unreadable (we will cover this in Module 3.05).

Part 2: The .DST File (The “Machine”)

The Analogy: Think of this like a PDF or a Connect-the-Dots puzzle. (Note: Your Shop Manager might refer to these dots technically as “X/Y Coordinates.”)

• What it does: It is “locked.” The machine acts like a blind robot reading a map. It doesn’t see a picture; it just reads thousands of tiny instructions: “Move Right, Move Up, Drop Needle.”
• Resize Limit: Max +/- 10% to 20%.
• The Trap: Because the file is just a fixed list of “dots,” the number of stitches is locked. If you shrink a DST by 50%, you squeeze 10,000 stitches into half the space. This creates a hard “bulletproof knot” that will break needles.

Part 3: The “Color Blindness” Issue

DST files are old technology. They often do not save colors correctly. You might open a file and see “Green” instead of “Red.”

• Do not panic.
• The Solution: Always send a PDF Proof (Worksheet) along with the DST. The operator uses the PDF to see the correct colors, and the DST to drive the machine.

The Golden Rule: Always request BOTH files. Archive the .EMB for future edits. Send the .DST + PDF Proof to production.
