File Prep
Before submitting files to Premier Print Group, please review the checklist below to ensure your project is press-ready. Proper preparation helps avoid delays and ensures the highest-quality results.
Include All Fonts
Include All Linked Images
InDesign’s Package function also bundles placed images. We highly recommend using it to avoid missing links.
Avoid Embedded Graphics
Linking to images rather than embedding them makes troubleshooting faster and reduces errors.
Use CMYK (Not RGB)
Convert all images to CMYK, duotone, or grayscale before submission. RGB images are for screens and will not reproduce correctly in print.
File Formats & Resolution
- Preferred formats: TIFF, EPS, PDF (Press Ready)
- Avoid: JPEG or GIF for print (acceptable only for web use)
- Photos: 300 ppi at final size (225 ppi minimum)
- Line art: 600–1200 dpi
- Scale images at 100% whenever possible to preserve quality
Set Bleeds at 1/8”
Extend artwork 1/8” beyond the trim edge for any full-bleed designs.
Verify Document Size
Set your layout to the correct finished size. Printer’s spreads are not necessary — we handle imposition.
Proofs
Digital proofs at 100% scale are preferred. If you cannot provide one, Premier Print Group can generate proofs for an additional fee.
Tips
Use Built-In Drop Shadows/Effects
Avoid applying artificial “type attributes” not included in the font set. InDesign/Illustrator drop shadow features are preferred for reliable output.
Gradients & Blends
Vector-based blends (Illustrator, InDesign) generally produce smoother results than Photoshop gradients.
Transparency & Effects
If using transparency or drop shadows, supply the native file (e.g., .indd, .ai) along with your exported PDF/EPS. This ensures full editability and correct color separation.
Image Tone Range
- Grayscale halftones: 3%–95%
- CMYK images: keep total ink coverage under 285% (K ≤ 93%) for best press performance.
Rich Black
For solid black backgrounds, use C63 M52 Y51 K100 for a deep, consistent black instead of 100% K alone.
Line Weight
Minimum recommended line width: 0.25 pt. Hairlines may disappear on high-res devices.
Folding Panels
For tri-fold brochures, make the inner panel slightly narrower (e.g., 3-5/8” instead of 3-11/16”) for clean folding.
Screen Tints
Avoid screens below 10% (may drop out) or above 90% (may fill in on press).
File Compression
When submitting digitally, compress your packaged files into a .zip archive. This prevents corruption during upload.
