  • What is the difference between RGB and CMYK colour modes?
    RGB (Red, Green, Blue) and CMYK (Cyan, Magenta, Yellow, Key/Black) are two different colour modes used in print design. RGB is used for on-screen displays such as computer monitors and televisions, while CMYK is used for printing with ink. The difference is that RGB uses light to display color and has a wider range of colours than CMYK, which has a limited color gamut due to the subtractive process of printing with ink. This means that not all RGB colours can be accurately reproduced in CMYK, resulting in colour shifts or a loss of vibrancy when converting from RGB to CMYK for printing. This is why it's important to design in CMYK for accurate colour representation in print.
  • What is the best resolution for printing?
    The best resolution for printing is 300 dots per inch (dpi). This resolution ensures that the printed image is sharp and clear, with no visible pixelation or jagged edges. A resolution of 300 dpi is considered the industry standard for high-quality printing, and is suitable for most printing applications including brochures, posters, and photographs. Keep in mind that increasing the resolution beyond 300 dpi does not necessarily improve the quality of the printed image, and can result in larger file sizes and longer print times. Conversely, using a lower resolution may result in a lower quality print, with visible pixelation or blurry details. To ensure the best print quality, it's recommended to always design and save files at a resolution of 300 dpi or higher.
  • What file format should I save my design in for printing?
    The best file format for printing depends on the type of design and the intended use. Here are some common file formats used in print design: PDF (Portable Document Format): A versatile file format that is widely accepted by printers and is suitable for designs that include text, graphics, and images. TIFF (Tagged Image File Format): A high-quality image format that is often used for printing photographs and other high-resolution images. JPG (Joint Photographic Experts Group): A common image format that is widely used for web and email, but may not be the best choice for printing due to its lossy compression. EPS (Encapsulated PostScript): A vector-based file format that is commonly used for logos, illustrations, and other graphics. AI (Adobe Illustrator): The native file format for Adobe Illustrator, a vector-based design software. It's often used for complex designs that require precise editing and scaling. It's important to check with your specialist to see which file formats they prefer and to ensure that your design will print correctly. In general, it's recommended to save designs in a high-resolution format, such as PDF to ensure the best print quality.
  • How do I add bleed to my design?
    Choose the right resolution: Large format printing requires a high resolution to ensure a sharp and clear print. A resolution of 150 dpi to 300 dpi is recommended for large format printing. Check colour mode: Make sure your design is in CMYK color mode as RGB colour mode is not suitable for printing with ink. Add bleed: If your design extends to the edge of the print area, add a bleed of at least 0.125 inch to ensure that the print goes all the way to the edge after trimming. Use vector graphics: Large format printing typically requires vector graphics, as they can be scaled to any size without losing quality. Convert any bitmap images to vector graphics, if possible. Proof your design: Review your design carefully and make any necessary changes to ensure that it will print correctly. It's a good idea to request a proof from your printer to ensure that your design will look the way you want it to when printed. Provide the correct file format: Provide your printer with the correct file format, such as PDF, TIFF, or EPS, that they require for large format printing. By following these steps, you can ensure that your design will print correctly and look great on large format prints.
