When designing letterheads with foil blocking, it's important to follow specific file formats and specifications to ensure optimal results. Here are our recommended guidelines:

File Format: It's best to provide your artwork in a high-resolution, print-ready file format. The preferred file formats for design are Adobe Illustrator (.ai), Adobe InDesign (.indd), or a print-ready PDF (.pdf).

Color Mode: Set your artwork to CMYK color mode, which is the standard for professional printing. Files supplied in RGB or spot colours will be converted to CMYK prior to printing.

Bleed and Trim: Include a bleed area of at least 3mm (0.125 inches) around all edges of your design. This allows for any slight shifting during printing and ensures that the foil blocking covers the intended area. Trim marks should also be included to indicate where the final trimming should occur.

Foil Artwork: Create a separate layer or file for the foil blocking elements. Use vector-based artwork for the foil areas, such as text, shapes, or patterns, to ensure sharp and precise results. Set the foil artwork to a spot color swatch named "Foil" or "Foil Blocking" and indicate the desired foil color.

Foil Blocking Specifications: Clearly indicate the areas where foil blocking should be applied using a contrasting color, such as a solid black or a spot color named "Foil." Provide clear instructions and notes regarding the desired placement, size, and orientation of the foil elements.

Fonts and Text: Ensure that all fonts used in your design are properly embedded or outlined to avoid any font-related issues during printing. Keep in mind that very fine or small text may not be suitable for foil blocking due to the level of detail that can be achieved.

Resolution and Image Quality: If your design includes images or photographs, make sure they have a resolution of at least 300 dots per inch (DPI) to ensure sharpness and clarity in print.
