Design File Set-Up Questions


Q: What file formats are best for high-quality printing?

A: For optimal results, especially in offset or high-end digital printing, it's recommended to use:

  • Adobe Acrobat PDF

  • Adobe InDesign (INDD)

  • Adobe Illustrator (EPS or AI)

  • Adobe Photoshop (PSD)


Q: What guidelines should I follow to prepare high-quality print files?

A: To ensure your files are print-ready:

  • Include crop marks to indicate where the paper will be trimmed.

  • Center your artwork within the trim box.

  • Keep non-bleeding text and images at least 1/8" inside the final product's edge to prevent accidental trimming.

  • Use the CMYK color space; other color spaces like RGB will be converted to CMYK, which might alter colors.

  • Ensure rasterized images are at least 300 dpi for clarity.

  • For rich black areas, use a CMYK build of 75% cyan, 70% magenta, 40% yellow, and 100% black.

  • Reserve 100% black (0% cyan, 0% magenta, 0% yellow, 100% black) for text, barcodes, QR codes, and mailing indicias.

  • Match your file's dimensions to the document's flat size.

  • Provide clear instructions with your files for any special requirements or layouts.

  • Avoid exceeding 300% total ink coverage to prevent paper saturation issues.

  • Print a mock-up to verify correct placement of folds and die-cuts.

  • Design thoughtfully to ensure folds don't disrupt your message or visuals, and handle crossover images carefully to avoid splitting text.


Q: What is bleed, and why is it important in printing?

A: Bleed refers to extending your design beyond the final trim size to ensure there are no unprinted edges in the final product. Typically, a 1/8" bleed is standard. Including bleed in your design ensures that colors and images reach the edge of the paper after trimming.


Q: What is CMYK vs. RGB color modes?

A: CMYK (Cyan, Magenta, Yellow, Black) is the color mode of your document that is used for printing, while RGB (Red, Green, Blue) is the color mode for digital screens. In your final design file, always make sure your document is set to CMYK color for accurate print colors.


Q: How can I ensure my images are of sufficient quality for printing?

A: High-resolution images are crucial for clear, professional prints. All rasterized images should be at least 300 dpi. Using lower-resolution images can result in pixelation and a loss of detail in the final product.


Q: What is DPI?

A: DPI (Dots Per Inch) measures print resolution. Higher DPI (300+) means better image clarity, while lower DPI (like 72) may appear pixelated.


Q: What is a flat size vs. finished size?

A: Flat size is the dimensions of your printed piece before any folding or binding. Finished size is the final dimensions after these processes are complete. For example, a brochure might have a flat size (laid out) of 8.5" x 11" but a finished size (folded) of 4.25" x 11" when folded.


Q: What file format is the BEST to export for printing?

A: PDF is the most reliable format for high-quality printing. Other good options include Native files like Adobe InDesign (INDD), Illustrator (AI), and Photoshop (PSD). If native files are provided, please make sure they are packaged correctly to include links and document fonts.


Q: What is the importance of file proofing before printing?

A: Proofing allows you to review and approve your design before it goes to print, ensuring that all elements appear as intended. It's an essential step to catch any errors or adjustments needed, saving time and resources.


Q: How should I prepare my files for a printer to avoid delays or errors?

A: To ensure a smooth printing process: Follow our printer's file guidelines, including format, resolution, and color space.

Project Print Material Questions


Q: What are some common finishing options available for printed materials?

A: Finishing touches enhance the look and functionality of your printed materials. Indexx Printing options include:

  • Binding: Methods like saddle-stitching, perfect binding, or spiral binding.

  • Coating: Applying gloss, matte, or UV coatings for protection and aesthetic appeal.

  • Die-Cutting: Creating custom shapes or designs within the print material.

  • Embossing/Debossing: Adding raised or recessed designs for texture.

These finishing techniques can significantly enhance the professionalism and attractiveness of your printed pieces.


Q: How do I choose the right paper stock for my project? 

A: The choice of paper stock affects the feel and appearance of your printed material. Consider factors like thickness (measured in gsm), finish (glossy, matte, uncoated), and color. Discussing your project's purpose with your project manager or sales team member can help determine the best paper choice.


Q: What is the difference between digital and offset printing?

  • Digital Printing: Ideal for short runs and projects requiring quick turnaround. It offers flexibility and cost-effectiveness for smaller quantities.

  • Offset Printing: Suitable for larger runs, providing consistent high-quality prints and a wider range of paper types and finishes.

Understanding these differences can help you choose the most appropriate printing method for your needs.


Q: How can I ensure color accuracy in my prints?

A: To achieve accurate colors:

  • Design in the CMYK color space, as it's standard for printing.

  • Calibrate your monitor to ensure on-screen colors match printed results.

  • Request a hard proof from your printer to see a physical sample before the full run.


Communicating with your printer about color expectations can also prevent discrepancies.
