YOUR GUIDE TO LOGO FILE TYPES

YOUR GUIDE TO LOGO FILE TYPES – IMAGE FILE TYPES EXPLAINED

As a branding/graphic design studio, we always provide the correct design files for the projects we work on to our clients, or the conclusion of a project to a printer for final output. Many times we get a call or an email from a frantic client worried that they can’t open one of the provided files or they don’t know what the file type is for.

Typically the files types the average person will not be able to open are the files with the extensions AI, EPS, and PSD. Each of these three file types require a special software programs used by designers, printers, signage manufacturers, and promotional product manufacturers.

If you hire a graphic designer to design your logo, make sure that you get the correct files once the logo is finalised.

VECTOR VS. PIXEL BASED GRAPHICS

Generally, designers will work in Adobe Illustrator to design your logo. Illustrator is a vector based program, rather than a pixel-based program like Photoshop. Vector-based images can be resized both larger and smaller without losing the image quality. Vector-based Illustrator files are created utilising smooth curves and lines and will reproduce exactly as they look in file. Generally speaking, pixel based images do not resize well. Pixel or bitmap based Photoshop files look digitised and have blurry/pixelated edges when resized from a low resolution file.

Here is a quick list of the different file extensions that we provide at the conclusion of a project, what each of them stand for, and how each file format can be used.

AI: ADOBE ILLUSTRATOR

AI files are vector files used by designers and commercial printers. AI files are scalable to any size and will never lose image quality. AI files can only be opened using Adobe Illustrator and may be created in layers. An AI file is one of the most preferred formats by printers, promotional product companies, signage companies and other third party creatives. If you have a logo designed professionally, you should ALWAYS be provided with an .AI file.

What is it suitable for? Stationery, Flyers, Business Cards or any other collateral that will be printed of high quality.

EPS: ENCAPSULATED POSTSCRIPT

EPS are vector files used by designers and commercial printers. EPS files are an industry standard file type, meaning “encapsulated postscript”. They can be imported into all major design programs. EPS is more of a universal file type (much like PDF) that can be used to open vector-based artwork in any design editor, not just the more common Adobe products. An EPS file is one of the most preferred formats by printers, promotional product companies, signage companies and other third party creatives. As with .AI files, if you have a logo designed professionally, you should ALWAYS be provided with an .EPS file.

What is it suitable for? Stationery, Flyers, Business Cards or any other collateral that will be printed of high quality.

PDF: PORTABLE DOCUMENT FORMAT

A PDF is a universal file format that preserves/embeds the fonts, images, layout and graphics of any source document, regardless of the application used to create it. PDF files can be shared, viewed and printed by anyone with the Adobe Reader software. PDF files can be used for commercial, digital, and/or desktop printing.

JPG: JOINT PHOTOGRAPHIC EXPERTS GROUP

A JPG file is a compressed image file that does not support a transparent background. JPG files can vary in resolution with high quality for desktop printing, medium quality for web viewing and low quality for email. When compressed repeatedly the overall quality of a JPG image is reduced.

What is it suitable for? Websites, Online Advertising, Email Signatures or anything web-related.

PNG: PORTABLE NETWORK GRAPHICS

The PNG file format is most commonly used for use online and on websites due to their low resolution. PNG files are bitmap images that employ lossless data compression, and like GIF files, PNG files can be created with a transparent background.

What is it suitable for? Websites, Online Advertising, Email Signatures or anything web-related.

DEVELOPING A LIBRARY OF FILES

Whenever we design a logo for a client, we provide a large library of final electronic files. The key files are the Illustrator files (.AI or .EPS), and we usually provide them in Pantone (PMS) colour, CMYK, RGB, grayscale, black and white versions. We also provide all the above file types mentioned in this post to ensure you get the best out of your amazing logo/corporate identity design.
