For print in large formatWhether it's a banner, a kakemono, or a totem, precision and careful file preparation are essential. One of the most common problems is pixelation. It results in a blurry or grainy image, which can damage your brand image. With Magicprint, simply follow a few best practices to guarantee a crisp, professional print.
Understanding pixelation
Pixelation occurs when an image is enlarged beyond its native resolution. Each pixel becomes visible, resulting in a blurry or degraded effect. This is particularly noticeable on text and fine details. Even if they appear fine on screen, low-resolution images can cause this problem in large formats. It is therefore essential to work with appropriately sized files.
Choosing the right resolution
To avoid pixelation, start with the image resolution. For large-format prints, it's recommended to use at least 150 dpi at the final scale, or even 300 dpi for highly detailed elements. Too low a resolution results in a loss of sharpness and an unprofessional appearance. Therefore, ensure your files meet these standards before sending them to Magicprint.
Prefer vector formats
Vector files, such as AI, EPS, or PDF formats, allow for infinite enlargement without any loss of quality. They are ideal for logos, text, and simple drawings. Unlike bitmap images (JPEG, PNG), they never pixelate when enlarged. For large-format printing, using vectors is highly recommended.
Check the file size
Even with good resolution, a file that is too small or compressed can result in a blurry image. Images must be sized according to the final print size. Magicprint recommends always providing files at actual scale or with a minimal enlargement factor. This ensures the best possible print quality.
Be careful with imported images
Images downloaded from the internet are often low-resolution and already compressed. They're suitable for the web but not for large-format printing. It's best to use your own high-resolution photos or obtain images from professional stock photo libraries. This avoids pixelation and ensures a sharp image.
Adjust the files correctly
Before sending your files to Magicprint, it is recommended to check several elements: resolution, format, size, and color accuracy. Image editing software allows you to correct contrast and control sharpness. A full-scale preview in your software will give you a precise idea of the final result.
Choose the right export format
For printing, we recommend using TIFF, high-quality PDF, or EPS files for vectors. JPEGs with minimal compression are preferable. The chosen format directly impacts sharpness and detail accuracy. Magicprint accepts these file types and ensures optimal results on all large-format media.
Working with an appropriate color space
The printable files Files must be in CMYK, not RGB. When converting from RGB to CMYK, colors can shift slightly, and pixelation can increase if the resolution is insufficient. Preparing files in the correct color space from the start prevents unpleasant surprises.
Importance of margins and lost funds
Even with a perfect image, a lack of bleed or margins can give the impression of blurriness or an imprecise crop. By including bleed of a few millimeters and respecting safety zones, a sharp image can be maintained right to the edge of the print.
Benefits of following these best practices with Magicprint
By following these tips, you'll create a clean, professional, and memorable print. Colors remain true to life, text is legible, and visuals are appealing. This increases the impact of your marketing materials and enhances your brand at your booths, in your shop windows, or at events.

4. Are internet images suitable for printing?
No, they are often compressed and too small for a sharp image in large format.
5. Should the files be prepared in RGB or CMYK?
Always use CMYK for printing, to avoid any unpleasant surprises with the colors.
6. What file size is required?
The files must match the final scale or be very close to it to avoid excessive enlargement.
7. What are lost funds and margins?
These are safety zones to prevent important elements from being cut during the cutting process.
8. Can Magicprint correct a pixelated image?
