Project done, logo finished, and then a folder full of files lands on your desk, with cryptic endings like .eps, .svg or .png. Which one do you need, and what for? Here's the short, honest overview.
When I finish a logo, you don't get a single file but a small, neatly sorted collection, ready for print and screen. Every format has its job. So you never have to puzzle again over which file goes to the printer and which belongs on the website, let me walk you through them.
For print
EPS in CMYK (positive & negative)
The all-rounder for anything printed. Infinitely scalable, from a business card to a large poster, and without a background, which also makes it ideal for plotting, e.g. vehicle or shop-window lettering. The positive version is meant for light backgrounds, the negative one for dark. It's an open format: only pass it on to partners you trust, so no one tampers with it uninvited.
JPG in CMYK
The uncomplicated choice for printing on a white background. Handy when the printer simply wants one finished, fixed file.
EPS in Pantone® (spot colours, optional)
For premium printing and promotional or give-away items where exact spot colours matter. Comes without a background as a path file.
For screen
JPG in RGB
Small and fast to load, ideal for digital office products such as presentations or letter templates. With a white background.
PNG in RGB (positive & negative)
The classic for the web. Transparent background, so the logo adapts to any surface. Again: positive for light areas, negative for dark ones.
SVG in RGB
Stays razor-sharp on a website no matter how large it's shown. Also an open format that can be downloaded and edited, so share it thoughtfully.
In short
A logo has to do one thing above all: work. Which file you need in the end depends only on where it appears, on paper, in a shop window or on screen. And if a format is ever missing: just say the word, and I'll add it for you.
