Goal
The goal of this project is to introduce the file types used in design production and to create a consistent and efficient process to manage files for use in print and digital workflows.
Objective
Provide an overview of print production related file types.

Lecture
The inclusion of the three letter extension on a file name is a good habit for Mac OS users. It allows for system recognition of digital files on severs, email, web or Windows OS. The following file types are commonly used in print and multimedia production. This list should not be considered complete or absolute due to near constant software updates and multiple authoring applications.
- Joint Photographic Experts Group-JPEG (.jpg):Photo, or continuous tone, images for the web. Millions of colors possible. Various settings allow for best quality to file size ratio. Should never be used for print production.
- Graphic Interchange Format-GIF (.gif):Flat color images for the web. Limited to 256 colors. Supports a transparancy option. Various settings allow for best quality to file size ratio. Should never be used for print production.
- Portable Network Graphics ‑PNG (.png):A combination of JPEG and GIF. Like the JPEG, the PNG supports Photo, or continuous tone, images for the web. Various settings allow for best quality to file size ratio. Like the GIF It supports transparency in an alpha channel or a designated color. Supported by most recent browser applications. Should never be used for print production.
- Hypertext Markup Language-HTML (.htm or html):WWW standard. Can be written is a text program such as SimpleText or Wordpad or in a web browser like Netscape or IE. Can be created by an external program such as Macromedia Dreamweaver or Adobe GoLive.
- Macromedia Flash-FLA (.fla): Vector animation and interaction program. Native authoring format. Allows EPS, JPG, GIF, AIFF and Quicktime import.
- Macromedia Shockwave-SWF (.swf): The presentation format of the Flash authoring files. These files are not editable on by other programs. Small file size makes Shockwave suitable for posting on the web or as an independent application.
- Macromedia Director-DIR (.dir): Image animation and interaction program. Native authoring format. Often decribed as more “robust authoring environment” than Flash, Director is older, and until late better for large graphics and video playback. Recent updates allow SWF integration as well as EPS, JPG, GIF, AIFF and Quicktime import.
- Macromedia Shockwave-DCR (.dcr): Not to be confused with the .swf, the .dcr file is a presentation format of the Director authoring files. These files are not editable on by other programs.Small file size makes Shockwave suitable for posting on the web or as an independent application.
- Macromedia Shockwave Projector (Projector or .exe): A self contained SWF or DCR file, except all software needed to play the file is embedded into the file. Files are platform specific to Mac (Projector) and to PC (.exe). Director requires a platform specific version to create this file.
- Apple Quicktime-MOV (.mov): Used for video, animation, and several sound formats. Allows for some links and interaction. Widely distributed to several computer platforms.
- MPEG3-MP3 (.mp3): (Also known as mpeg 1, layer 3) — A compressed audio file format that uses psychoacoustic modeling to reduce file size significantly, while retaining good audio quality. Popular for use on the Internet and in personal music players.
- MPEG4-AADCM (.mp4): Advanced Audio Coding — (Also known as AAC, MP4, or mpeg 1, layer 4) — A compressed audio file format that uses psychoacoustic modeling to reduce file size significantly, while audio quality rivals that of uncompressed CD audio. MP4 is a fairly new standard and rising in popularity for use on the Internet and in personal music players.
- Windows Audio Wavform-WAV (.wav): Sound files used by Windows OS. Can be read by Quicktime and others on Mac OS.
- Audio Interchange File Format-AIFF (.aif or .aiff): Sound files used by Mac OS and on commercial CD’s. Can be read by Quicktime and others.
- iMovie: Video editing files that combine raw source files into one (no links). Large file size may make difficult to transport. Read by some Apple products (Mac OS only).
- iDVD: DVD video authoring program. Read by some Apple products (Mac OS only).
- Final Cut Pro (.fcp): Professional video editing software. Reads, imports and exports many different audio and video formats.
- Adobe Flash Video (.flv and f4v): Flash container for video codecs, primarily H.264 and VP6.
- Adobe After Effects (.aep): Motion animation in 2D and simulated 3D space.
- Maya (.obj): 3D modeling and animation program.
- Scalable Vector Graphics (.svg) Open standard format for static and motion vector graphics, comprable to Adobe Illustrator and Flash, respectively. Limited functionality and implementation.
- MS PowerPoint (.ppt): Basic presentation software that combines graphics and text. Universal to most computers (PC) if system fonts are used.
- Disk Image (.dmg): Used as a CD rom to transport groups of information (like installation disks). Usually ready only.
- Scalable Vector Graphics (.svg) an open standard format for static and motion vector graphics, comprable to Adobe Illustrator and Flash, respectively.
