Mulé Design & Illustration can deliver your graphic design, illustration or logo in any many different sizes and in a .eps., .gif, .jpg, .psd, .wmf, .tiff file, or as a resizable vector .eps file.

We accept the following file formats for use in our design department. Please contact us with any questions. All files and disks need to be PC formatted.

Here is a description of the most popular file types:

FILE FORMATS

Photoshop (.psd) Photoshop’s native file format supports all the program’s capabilities. Files in this format can be placed in the latest versions of InDesign and GoLive as smart objects and can be opened in Adobe Illustrator. This is the default file format. Most workflows (but not all) benefit from maintaining a file in Photoshop format until it’s time to create a final TIFF, EPS, JPEG, or other file. It’s also usually a good idea to maintain the original image, with editable type and layers, for future use.

CompuServe (.gif) GIF is a common Web file format, suitable for illustrations and other images with large areas of solid color and no or few gradients or blends. Many logos and cartoons, as well as Web navigation items, such as banners and buttons, are appropriate for GIF. This file format is not appropriate for most photographs and other continuous-tone images because it can record a maximum of only 256 distinct colors. (A photograph might have thousands or millions of individual colors.) Although very small and adequately detailed thumbnails of photographs can be created as GIFs, a continuous-tone image typically suffers from posterization. When areas of similar (but not identical) color are forced into a single tint, the image quality can suffer severely.

Encapsulated PostScript (.eps) PostScript is a page description language developed by Adobe, and it was at the heart of the desktop publishing revolution of the 1990s. An Encapsulated PostScript (EPS) file can contain any combination of text, graphics, and images and is designed to be included (encapsulated) in a PostScript document. EPS files contain the description of a single page or an element of a page.

EPS is typically used for elements to be included in a page layout or PDF document. Because PDF files can be designed for onscreen display as well as print, EPS supports the RGB color mode in addition to the CMYK and Grayscale modes. EPS files cannot be displayed by Web browsers (although they can be incorporated into PDF files, which can be shown through a browser plug-in). One of the greatest advantages of EPS as a file format is the capability of including both raster and vector data and artwork.

JPEG (.jpg) Joint Photographic Experts Group (JPEG) is technically a file compression algorithm rather than a file format. The actual file format is JFIF (JPEG File Interchange Format), although JPEG is more commonly used. JPEG supports Grayscale, RGB, and CMYK color modes and can be used with files more than four times as large as Photoshop’s 30,000×30,000 pixel maximum. JPEG does not support transparency, alpha channels, spot colors, and layers. Paths can be saved with a JPEG file, including clipping paths (although most programs can’t use the clipping path, with the notable exception of InDesign). Type is rasterized when a file is saved as JPEG.

JPEG is commonly used on the Web for photographs and other continuous-tone images in which one color blends seamlessly into another. Because of its support for 24-bit color (in RGB mode), JPEG is far better than GIF for displaying the subtle shifts in color that occur in nature. (Rather than GIF’s maximum of 256 distinct colors, JPEG files can include more than 16.7 million colors.) JPEG is the most common file format for digital cameras because of the outstanding file size reduction capabilities.

Portable Document Format (.pdf) Adobe’s Portable Document Format (PDF) is a cross-platform format that can be opened and viewed in the free Acrobat Reader, available for most computer operating systems. PDF is, at heart, a PostScript file format. Photoshop breaks PDF into two categories: Photoshop PDF and Generic PDF. Both can be opened, but only the former can be created. Photoshop PDF supports all of Photoshop’s color modes, transparency, vector type and artwork, spot and alpha channels, and compression (JPEG or ZIP, except for bitmap images, which use CCITT-4 compression).

Portable Network Graphics (.png) Developed as an alternative to GIF and JPEG for the Web, Portable Network Graphics (PNG) comes in both 8-bit (Indexed Color) and 24-bit (RGB) variations. JPEG’s lossy compression and the licensing requirement associated with GIF’s compression lead to the demand for an alternative. PNG-8 and PNG-24 are both now widely supported by Web browsers.

TIFF (.tif) Tagged Image File Format (TIFF) and EPS are the two most widely accepted image formats for commercial printing. TIFF files can be produced directly by most desktop scanners and many digital cameras. The format supports CMYK, RGB, Lab, Indexed Color, Grayscale, and Bitmap color modes. In Bitmap mode, alpha channels are not supported, but they are available in all other color modes. Spot channels are supported, and clipping paths can also be saved with TIFF images to denote areas of transparency.
