Artwork File Formats
We want to make it easy for clients to submit artwork files to ensure a crisp clean print every time. The formats in which these files are submitted vary depending on their intended purpose so please take a moment to familiarise yourself with these preferences.
To start with here are some general guidelines:
- If the images are for the Web or online, use JPEG, PNG, or GIF. (72 dpi versions)
- If the images are for print, use .EPS (Vector), .PDF (Vector) or .TIFF (300dpi).
- If you want to keep a version that remains editable, choose your software’s native file format. (PSD for Photoshop, PSP for Paint Shop Pro, CPT for Corel Photo-Paint, etc.)
- If you want to supply a file to a printer use a .PDF or .EPS
JPEG – Joint Photographic Experts Group
Best used for web
JPEG is a lossy compression technique (also known irreversible compression) as for colour images. It can reduce files sizes to about 5% of their normal size, some detail is lost in the compression. This is why it is used predominately for websites. The file sizes are low which is great for speeding up site loading times.
TIFF – Tagged Image File Format
Best for storing original graphics and for use on printed materials.
Best for versatility – can be used with most programmes
TIFF is a lossless file type. No data or quality is lost when saved. TIFF is the most universal and most widely supported format across all platforms, Mac, Windows, Unix. It’s used for storing original images or artwork so they can be manipulated or saved as other formats at a later date.
PNG – Portable Network Graphics
Is a lossless bitmap image format. PNG was developed to deal with some of the limitations of the GIF format and allows storage of images with greater colour depth and other important information. It is commonly used for logos on the internet.
PSD – PhotoShop Document
Best for manipulating images/photographs using the Adobe Photoshop program
The PSD format was developed by Adobe, the maker of the PhotoShop software package which is a graphic design / digital imaging program. PSDs are generally created and manipulated using the PhotoShop application. They are a predominantly used for editing and manipulating graphics and images.
EPS – Encapsulated PostScript File
Best for printed materials and manipulating images
This file may contain 2D vector graphics, bitmap images, and text. EPS files are supported by several different drawing programs and vector graphic editing applications. They are often used to supply graphics in an original and high quality state.
PDF – Portable Document File
This file format is used for representing documents in a way that is independent of application software, hardware, and operating systems. Documents are saved in PDF format when users are likely to want to print information and won’t need to alter the document. They can also be offered on a website so that immediate access is given to certain information. These files can either be read in a browser or downloaded to your computer.
Lossy compression – is a data encoding method that compresses data by discarding (losing) some of it. The method aims to lessen the amount of data that needs to be held, and/or sent by a computer.
Lossless compression – is a form of data compression that allows the exact original data to be reconstructed from the compressed data. Lossless compression is used in cases where it is important that the original and the decompressed data be identical, or where differences from the original data could be damaging.
