Sending print-ready files saves time, money, and avoids the frustration of costly reprints. Whether you're preparing business cards, brochures, banners, or packaging artwork, getting the file right before it goes to press is the most important step in the entire process. This comprehensive checklist covers every requirement your files need before submission to a professional printer in Dubai — applicable to any print job, any size.
What is a "Print-Ready" File?
A print-ready file is artwork that has been properly configured to produce accurate, high-quality results when sent directly to a printing press — without requiring any intervention from the printer's prepress team. It contains the correct colour profile, sufficient resolution, proper bleed and safe zones, and has all fonts and images embedded or outlined. A truly print-ready file eliminates guesswork and ensures that what you see on screen is faithfully reproduced in the final print.
Submitting files that don't meet these specifications is the single biggest cause of delays, reprints, and unexpected results. The good news is that once you understand the requirements, preparing a correct file takes only a few minutes.

Understanding Bleed and Crop Marks
Bleed is one of the most frequently misunderstood concepts in print preparation, but it is straightforward once understood. When a sheet is printed and then trimmed to size, the cutting blade is mechanically precise — but not perfectly precise. Even a fraction of a millimetre shift can result in a thin white border along the edge if the background colour or image stops exactly at the trim line.
The solution is to extend your background — the colour, pattern, or image that goes to the edge — 3mm beyond where the paper will be cut. This 3mm zone is the bleed area. Your final design is trimmed within this zone, so the edge always appears clean.
Setting 3mm bleed in Adobe Illustrator:
- Go to File > Document Setup
- In the Bleed section, enter 3mm for Top, Bottom, Left, and Right
- Extend any background elements to the red bleed guide line
- When exporting PDF: File > Save a Copy > Adobe PDF > check "Use Document Bleed Settings" in the Marks and Bleeds tab
For InDesign: Set bleed in File > Document Setup > Bleed and Slug. For Photoshop: add 3mm canvas on each side, then flatten and export — note that Photoshop is not ideal for multi-page print documents.
CMYK vs RGB — Why It Matters
Screens (monitors, phones, tablets) display colour using light, mixing Red, Green, and Blue channels — this is the RGB colour model. Printers, by contrast, apply physical inks: Cyan, Magenta, Yellow, and Key (Black) — this is CMYK. These two systems have fundamentally different colour gamuts. RGB can display a much wider range of vivid colours than CMYK can reproduce in ink on paper.
This means that a design created in RGB and then sent to print will undergo colour conversion — often with visible results. Bright blues shift towards purple. Vibrant greens become duller. Electric magentas lose their intensity. The solution is to design in CMYK from the start, or to perform a careful CMYK conversion before finalising your file, reviewing the result on a calibrated display.
Watch out: Even if you set your document to CMYK, imported images may still be RGB. Check every placed image by selecting it and reviewing its colour mode in the Links panel (InDesign) or Embed dialog (Illustrator). Convert RGB images to CMYK in Photoshop before placing them.
Resolution Requirements for Different Print Types
Resolution in print is measured in DPI (dots per inch) — the number of ink dots per inch of printed output. The higher the DPI, the sharper the result. Requirements vary by print type:
- Standard commercial print (business cards, brochures, flyers, stationery): 300 DPI minimum at the final print size. This is the industry standard for crisp, professional results viewed at close range.
- Large format / wide format (banners, signage, rollup stands): 150–200 DPI at final print size is typically sufficient. Large format prints are viewed from a greater distance, so the eye cannot resolve the individual dots at lower resolutions. Supplying 300 DPI at large format sizes results in unnecessarily huge files.
- Billboard / super-large format: 72–100 DPI at final size is often used, as viewing distances are significant. Always confirm with your printer.
Important: Resolution must be correct at the final print size, not at the original file size. A 72 DPI image looks fine on screen but will print poorly. You cannot "increase" resolution by resampling upward in Photoshop — this adds artificial pixels and does not improve print quality. Always start with a high-resolution original.
Common File Preparation Mistakes to Avoid
Submitting in RGB Colour Mode
The most common error. Always convert to CMYK before exporting. RGB files sent to a CMYK press produce unpredictable colour results that often cannot be corrected without a reprint.
No Bleed Added
Files without bleed are either rejected or printed with a white border. Add 3mm bleed to every edge before exporting. This is non-negotiable for any edge-to-edge design.
Low-Resolution Images
Screen-resolution images (72–96 DPI) look sharp on a monitor but print soft and blurry. Always source 300 DPI images or use vector graphics that scale infinitely.
Fonts Not Outlined or Embedded
If a printer doesn't have your font installed, it will substitute a default — completely changing your typography. Always outline text or embed fonts in your PDF export.
Critical Content Too Close to the Edge
Text or logos placed right at the trim line risk being clipped. Maintain a 3mm safe zone inside all edges. This is separate from — and in addition to — the bleed requirement.
Sending Editable Files Without Packaging
AI or INDD files sent without packaging (linking all assets and fonts in one folder) will open with missing elements. Always package, or export to PDF instead.
