What Resolution Do I Need to Print a Banner?
When it comes to printing banners, there are several factors to consider. You need to think about formats, size and resolution, color, etc. But size and color are often a matter of preference and formats are chosen based on the option that will give the best outcomes. So, what about resolution? What resolution do I need to print a banner?
What Resolution Do I Need to Print a Banner? — The Ultimate Guide
In this article, we’ll discuss the art requirements of banner printing including everything from the size and resolution to the formats and color.
Preparing Files for Digitally Printed Banners
Generally, you can save files from most operating system platforms and graphics software in the following formats:
- PDF (Portable Document Format) — You can also use this format in comparison to JPEG files when printing items.
- AI (Adobe Illustrator)
- PSD (Adobe Photoshop)
- EPS (Encapsulated PostScript)
Color
When it comes to color, files can be saved in both CMYK and RGB color modes although some printing firms will prefer one or the other. To avoid producing unexpected results, avoid mixing color modes. When color is critical, you want to avoid flattening the layers or embedding images. It’s always better to link to any images and leave the layers intact as that will make it easier to work with.
Size and Resolution
You want to set up your final document in proportion to your desired resolution and final output size.
Vector Files
These types of files are based on lines rather than pixels, which means you can scale them without losing resolution. Therefore, the final product will not become jagged or pixilated when it’s enlarged. The most crucial element when dealing with vector files is that they’re set up proportionately to the final output size.
Raster Files
If the banner is to be viewed beyond 24”, experts recommend a resolution of 150 dpi. For a sign or banner that’s to be viewed at less than 24”, the recommended resolution at the final size should be 300 dpi. For very large banners or signs that are going to be viewed from a distance, a resolution of 100 dpi should work fine and even make it easier to work with the files.
Scaling
When scaling raster-based files, it’s important to consider that doubling the size of the artwork drops the resolution by half. This is a critical consideration-especially when creating your original artwork.
Compression
Unless you have no alternative option for original files, you want to avoid compressing the files or using any compressed format such as JPEG.
Scanned Images
Bear in mind that the resolution decreases by the same factor as the enlargement. So, if you have a 300-dpi original image enlarged to four times the original size, the final resolution will be 75 dpi. It’s advisable, therefore, to ensure scanned images have a resolution of no less than 300 dpi at 1/4 of the final printed piece.
Bottom Line
What resolution do I need to print a banner? The short answer is that it depends on the factors mentioned above when you’re looking into large format printing services. You need to consider the result you want to achieve. It also helps to ask for professional advice and consult the printing company if you’re not sure.
