Why there is not just one correct file
Your logo may be the same everywhere – but the file requirements are not. After all, a social media post needs different specifications than a T-shirt print or a business card.
Important to understand:
-
Not every file format is suitable for everything
-
Colour modes such as RGB and CMYK determine whether your design looks good on screen or in print
-
The Resolution (dpi) decides whether the whole thing is pixelated or crisp and sharp
It sounds like nerdy stuff, but it's the be-all and end-all for a consistent – look and saves you nerves when working with print shops, service providers or online shops.
File formats: Which for what – an overview
In design, we basically distinguish between two file formats: Raster graphics, which consist of individual pixels, and Vector graphics, which can be scaled without loss.
Raster formats – for photos & web graphics
These formats consist of Pixels and are Not infinitely scalable:
-
JPG / JPEG
-
Most common format for photos
-
Compressed, therefore smaller file size
-
No transparency possible
-
Good for: Web, social media, newsletter
-
-
PNG
-
Supports transparency (e.g. for logos without background)
-
Compressed without loss
-
Larger than JPG
-
Good for: Websites, presentations, small printed matter
-
-
TIFF
-
High-quality image format without loss of quality
-
Very large file size
-
Good for: professional printing, archiving
-
Vector formats – for logos, icons & printing
These formats consist of mathematical forms and are Scalable as required – without any loss of quality:
-
SVG
-
Ideal for web and responsive designs
-
Small file size, but not printable everywhere
-
Good for: Websites, online icons, illustrations
-
-
EPS
-
Classic vector format for printing
-
Often required by printers
-
Good for: Posters, banners, advertising material
-
-
PDF
-
Universal format for print data
-
Can contain both raster and vector data
-
Good for: Print approvals, proofs, flyers, brochures
-
Tip from us: Always ask your agency to a selection formats. So you are equipped for all applications – from the website to the exhibition stand.
Colour mode: RGB vs. CMYK – Screen or print?
Colours are not the same as colours – at least not digitally. The question is: Does the colour light up (RGB) or is it printed (CMYK)?
RGB – for digital applications
-
Stands for Red, green, blue
-
Colour mode for Monitors, smartphones, websites
-
Bright, powerful, lively
-
Colour space is larger, but not printable
CMYK – for printing
-
Stands for Cyan, magenta, yellow, key (black)
-
Colour mode for Print products of all kinds
-
Colours often appear duller than on the screen
-
Important for: Business cards, posters, brochures, packaging
Important: RGB data looks great on the screen, but can be disappointing in print. Therefore, all print data must always be in CMYK converted – are ideally already before the design process, to avoid unpleasant surprises.
Resolution: What does dpi actually mean?
dpi = dots per inch –, i.e. how many pixels are displayed per inch. The higher the number, the sharper will be the result. But: Not everything needs 300 dpi.
The most important dpi values at a glance:
-
72 dpi
-
For: Web, screen, social media
-
Completely sufficient for digital display
-
Fast loading, small file size
-
-
150 dpi
-
For: simple office printouts, presentations
-
-
300 dpi
-
For: professional printing
-
Business cards, flyers, brochures, packaging
-
-
600+ dpi
-
For: very fine prints, e.g. art prints or labels
-
Fun Fact: An image with 72 dpi looks good on the screen, but pixelated and blurred in print. Conversely, a 300 dpi image is oversized for the web and results in long loading times.
What does this mean for sustainable companies?
Sustainability doesn't end with eco-paper – but starts with the paper itself. Clear communication of your brand. If you:
-
uses the right formats for each channel,
-
colour profiles consistently and
-
work with a smart resolution,
...you not only avoid mistakes, but also unnecessary reprints, Returns or hours of queries with the print shop. This saves Resources, nerves and CO₂.
It's all a question of form(at)s
Whether website, business card or gift box – the file must match the application. And that is precisely why it is so important to know the differences between JPG, PNG, EPS & Co. RGB vs. CMYK? dpi? Sounds technical, but it's essential for working professionally, efficiently and sustainably.
