The Ultimate Print Production Guide & Prepress Checklist

Welcome to the ultimate resource for print production, graphic design file preparation, and commercial printing terminology. Whether you are a seasoned graphic designer or a business preparing a marketing campaign, this guide covers everything you need to know to achieve flawless print results.

1. About Digital City Printing

Located in the heart of NYC at 519 8th Avenue, 3rd Floor, New York, NY 10018.   Digital City Printing has been the trusted printer for businesses and individuals since 2008.

We specialize in premium printing services, including:

  • Digital Printing: Utilizing HP Indigo digital presses with liquid HP ElectroInk technology for offset-quality results.

  • Offset Printing: For large-volume, high-quality commercial runs.

  • Large Format Printing: Billboards, banners, and window displays.

  • Specialty Printing: Same-day and rush printing options.

2. Print Production & Graphics Terminology

Understanding print terminology is the first step to successful print production.

  • Bleed: Artwork that extends beyond the final trim edge (usually 0.125 inches) to accommodate minor paper shifts during cutting.

  • Trim: The final dimension of your printed product after the bleed is cut away.

  • Live Area (Safe Margin): The designated safe zone where typography and essential graphics should remain to avoid being trimmed off.

  • DPI (Dots Per Inch): A measure of printing dot density; higher DPI results in sharper print quality.

  • PPI (Pixels Per Inch): A measurement of pixel density used for digital displays and scanners.

  • Raster Images: Pixel-based graphics (like JPEGs and TIFFs) that will blur or distort if enlarged past their original resolution.

  • Vector Images: Math-based graphics (like AI and EPS files) that can be infinitely resized without losing quality.

3. File Formats & Graphic Software Best Practices

Using the right software and file format ensures your files are print-ready.

  • Adobe InDesign (.INDD): The industry standard for multi-page layouts, such as booklets, catalogs, and newsletters.

  • Adobe Illustrator (.AI): Ideal for vector artwork, logos, and single-page designs.

  • Adobe Photoshop (.PSD): Best for editing raster images and photos; not recommended for typesetting.

  • Print-Ready Formats: Submit your files as high-resolution PDFs or TIFFs.

  • Web-Only Formats: PNG and GIF files are low-resolution and should never be used for commercial printing.

4. Color Theory: CMYK, RGB, and Pantone

Color accuracy is crucial in commercial printing.

  • CMYK Color Mode: The standard four-color print process (Cyan, Magenta, Yellow, Key/Black). All files must be converted to CMYK before submission.

  • RGB Color Mode: The light-based color scheme (Red, Green, Blue) used for monitors. RGB has a wider color gamut and will look duller if not properly converted to CMYK.

  • Rich Black: For a deep, saturated black, use the CMYK formula: C=60, M=40, Y=0, K=100.

  • Avoiding Purple Blues: Blue and purple sit close together in the CMYK spectrum. Always maintain at least a 30% difference between your Cyan and Magenta values to keep blues looking blue.

  • Pantone Colors (PMS): An international standard for exact ink matching. When printing in CMYK, Pantone colors mixed with transparent images or drop shadows can cause errors. Convert them to CMYK prior to submission.

5. Prepress Setup and Exporting Guidelines

  • Image resolution must be exactly 300 DPI for standard printing. Bitmaps should be 600 DPI.

  • Extend all document bleeds by 0.125 inches (1/8″) on all sides.

  • If ordering specialty finishes like Spot UV or Foil Stamping, you must provide separate mask files. Mask files must have a white background, with the designated finish area colored in 100% K (Black). Avoid using Spot UV on very thin text, as a 1/16″ production shift can occur.
