1. File Format

• Preferred Formats: Use formats like PDF for high-quality prints. Avoid using Word documents or images from Word, as they may not print correctly.
• Resolution: Ensure images are at least 300 pixels (per cm) for clear, sharp prints.

2. Color Mode

• CMYK vs. RGB: Convert your files to CMYK color mode for printing. RGB is suitable for screens but may not translate well to print.
• Keep in mind that colors in print may vary from what you see on your screen. This is due to differences in how screens and printers display colors.

3. Bleed and Margins

• Bleed: Add a bleed area of at least 0.5 cm around your document. This ensures that there are no white edges when the paper is trimmed.
• Margins: Keep important text and images at least 0.5 cm away from the edge of the page to avoid being cut off.

4. Fonts

• Embedding Fonts:
  • When saving your document as a PDF, make sure to select the option to embed fonts. This ensures that the fonts you used will display correctly, even if the printer does not have them installed.
  • In Adobe Acrobat, you can check font embedding by going to File > Properties > Fonts.
• Creating Outlines:
  • Convert text to outlines to avoid font issues. In Adobe Illustrator, select the text, then go to Type > Create Outlines. This will turn the text into vector shapes.
• Font Size: Use a minimum font size of 10pt for readability.

5. Images

• Embedding Images: Ensure that all images are embedded in your document. In Adobe InDesign, you can do this by selecting the image and choosing Links > Embed Link. This prevents issues with missing images when the file is sent for printing.

6. Proofing

• Print a Proof: Always print a proof copy to check for any errors in layout, color, and text before final printing.

7. File Size

• Optimize File Size: Compress images and optimize your file to ensure it is not too large for the printing service. However, maintain quality.
