    Folding Services

    Folded Right. Mailed Ready.

    Precision machine folding for letters, brochures, flyers, and self-mailers — every fold perfect, every time.

    What Is Folding Services?

    Folding is the mechanical process of creasing and folding printed sheets into the configuration needed for mailing or presentation. Folding machines use precision rollers and guides to produce consistent results across large quantities. A clean fold is essential for self-mailers to meet USPS requirements and for inserts to fit properly in envelopes.

    Catdi Printing's folding department handles all standard and custom fold types for direct mail and marketing materials. From simple half-folds on letter-sized paper to complex accordion folds on large-format sheets, our equipment delivers clean, consistent folds at production speed — ready for inserting, mailing, or distribution.
