Graphic design and print production involve a strong creative component. However, achieving the best results also requires technical precision, especially when preparing files in the correct formats for print. Below, we explain the key concepts to ensure optimal results.
What types of file formats exist? Which are used for print?
Although technology has simplified professional printing processes, it is still essential to understand the technical aspects required to prepare files correctly.
In practice, these are the main file formats used in print production:
- PDF: This standard format, prepared in high resolution, streamlines prepress and ensures reliability. It should always be used whenever possible.
- TIFF: Ideal for large-scale work, as it preserves image quality. It is compatible with most software. However, due to its size, it can be less practical to handle.
- EPS: Recommended when working with extractable images, vector graphics or bitmap files. It is important to complete the file preparation process correctly before use.
- JPEG: Although widely used, it is not recommended for print production, as images lose quality. It is only acceptable in specific cases, such as certain POS materials.
- Open files (editable formats): These are files from design software such as Adobe Illustrator, InDesign or QuarkXPress. They include linked images and fonts. Their use increases the risk of errors, so they should be avoided whenever possible.
File size formats
In addition to file formats, document dimensions must also be correct. Otherwise, the final result may not match expectations or may require adjustments during printing. DIN standards are typically used:
- Business cards: 8.5 × 5.5 cm / 9.0 × 5.0 cm
- B6 format: 10.0 × 21.0 cm
- A6 format: 14.8 × 10.5 cm
- A5 format: 21.0 × 14.8 cm
- A4 format: 29.7 × 21.0 cm
- A3 format: 42.0 × 29.7 cm
- A2 format: 59.4 × 42.0 cm
- A1 format: 84.1 × 59.4 cm
- B2 format: 50.0 × 70.0 cm
When preparing these files, you should also consider whether to include bleed and how it will be applied for trimming.
Tips and steps to prepare a print file
To ensure a correct print production process, follow these key steps:
- Check and adjust the document size to ensure it is correct.
- Always use CMYK colours. If RGB is used, differences will be noticeable in print.
- Include a bleed margin of 3 to 5 mm, especially if the design extends to the edge.
- Use images with a resolution of 300 dpi. For large-format printing, 72–150 dpi may be sufficient (confirm depending on viewing distance).
- Embed all linked images.
- Convert fonts to outlines (curves).
- Carry out a print proof or request one, especially for gradients.
- Carefully proofread all content before final approval.
