JPEG: The joint Photographic Experts Group developed the Jpeg file. This format was created for a standard for color and grayscale images; it only works on continuous tone images. The big advantage of this file is the compression that the file allows. It uses a lossy compression scheme that will throw out data to compress the file as much as 10:1.
One important characteristic that affects these files is the compression scheme used to compress the file. Compression schemes fall into two categories: lossless and lossy. Lossless compression allows the file to be compressed without losing any data. Lossy compression works by removing some of the data so quality can suffer.
Corel Draw .CDR / Illustrator .AI: They are object-oriented graphics. They overcome the limitations of bitmaps. The images are composed of mathematically described objects and paths, some strokes as a list of drawing instructions compiled from menu choices and mouse actions. You can enlarge, reduce, rotate, reshape, and refill without losing the quality. These graphics are resolution-independent.
TIFF or TIF: Acronym for tagged image file format, one of the most widely supported file formats for storing bit-mapped images on personal computers (both PCs and Macintosh computers).
TIFF graphics can be any resolution, and they can be black and white, gray-scaled, or color. Files in TIFF format often end with a .tif extension.
Encapsulated Postscript (EPS): Is actually Postscript file with a preview. It is used for storing both object oriented artwork and bitmapped artwork. If an object-oriented image is saved in the EPS format, it will retain its resolution-independent printing quality, and in most cases cannot be ungrouped, refilled or re-colored. It can be resized, distorted, or cropped.
Adobe Portable Document Format (PDF): It is an excellent file format for file exchange due to its portability and cross platform characteristics. It preserves the exact look and content of the originals complete with fonts and graphics and can be printed and distributed by email, share or store it on the web.
To avoid delays and possible errors please convert all text to curves before sending files to us. If you have problem using these functions, just export the files to be used as EPS format and send it to us. This will solve your problem of using these functions.
