From Screen to Print: The Designer’s Ultimate Guide to Avoiding Printing Disasters

We see it often: a digital design looks stunning on a Retina display, but the final printed product looks disappointing. Colors are muddy, images are blurry, or important text gets cut off.

Conversely, some designs look simple on screen but turn out magnificent in print. What’s the difference? Print Knowledge.

A great designer understands that the screen is just a preview; the press is the reality. To help you bridge the gap between digital creativity and physical production, here is the essential guide to preparing print-ready files.

1. Dimensions: Why A4 Isn’t Always the Right Choice

Many designers default to standard A4 (210x297mm) for brochures. However, in professional offset printing, we often recommend the “Large 16K” size (210x285mm).

Why? It’s about cost and waste. Printing presses use massive sheets of paper. The 210x285mm size fits perfectly onto these standard sheets with minimal waste. Forcing a 297mm height often means fewer pages per sheet and significant paper waste, which drives up your printing costs unnecessarily.

Rule of Thumb: Check the standard “finished size” with your printer before you start designing.

2. Resolution: The 300 DPI Rule

Resolution is the number of pixels within a physical space. It is the most common cause of blurry prints.

• 300 DPI: Required for brochures, packaging, flyers, and business cards. (Note: A 72 DPI image looks great on a screen but will look pixelated and “blocky” when printed.)
• 150 DPI: Acceptable for large format items viewed from a distance, like Roll-up Banners or X-Stands.
• 30-50 DPI: Used for massive outdoor billboards.

Tip: If you are using vector software like Illustrator, you don’t need to worry about resolution until you export photos or effects.

3. Bleed: The Safety Margin

Bleed is the area of your design that extends beyond the final cut line. Paper cutting machines are precise, but not perfect. If you don’t add bleed, you risk having ugly white slivers on the edge of your brochure.

Standard Requirement: Add 3mm of bleed on all four sides. Keep all critical text and logos at least 3-5mm inside the trim line (Safe Zone). If you forget this, our pre-press team will try to fix it, but it’s always best to design it right from the start.

4. Color Mode: RGB vs. CMYK

Screens emit light (RGB: Red, Green, Blue). Paper reflects light (CMYK: Cyan, Magenta, Yellow, Black).

• The Shift: RGB colors are vibrant and bright. CMYK inks are naturally darker. Some color shift is normal.
• Rich Black vs. Standard Black: For small text, use K:100 (Standard Black) only. Never use 4-color black (e.g., C100 M100 Y100 K100) for text, as slight misregistration will make the text look blurry.
• Minimum Ink: Avoid colors with less than 8% total value, as they may not print clearly.

5. The Pre-Press Checklist

Before you send your file to Kore Create, run this quick audit:

1. Outline Fonts: Convert all text to paths/outlines to prevent font substitution errors.
2. Line Weight: Ensure all lines are at least 0.2mm (0.57pt). Hairlines visible on a screen may vanish on a printing plate.
3. Check Overprint: Ensure white text is NOT set to overprint (it will disappear). Ensure black text IS set to overprint.
4. File Format: A high-quality PDF is the industry standard.

Conclusion

Good design is more than just aesthetics; it’s about technical execution. By following these standards, you ensure that the final product matches your vision.
