At present, in digital printing, the widely used file formats for image storage generally include EPS, TIFF, and JPEG. The EPS and TIFF formats are the two basic formats that designers are most interested in. The difference in format is good for using them well.
The EPS format is called the PostScript format. As you know, the PostScript language is a page description language designed by Adobe. When you work on a PostScript printer and tell the word processor to print the page, the computer writes a program in PostScript to describe the page and pass the program to the printer for printing. An EPS file is a PostScript file that includes header information. The header information can be used by other applications to embed this file in the document. The EPS format is a mixed image format that records images, graphics, and text in a single file at the same time, carrying relevant text information. This format is supported by most drawing and typesetting software. EPS is also the only file format that supports transparent white in binary image mode, that is, the transparent area defined in the image processing software can be well inherited in the typesetting software. The EPS format is mainly used for printing and printing. It can store alpha channels, especially for storing paths and screening information, while TIFF does not allow such information to be included in image files.
The TIFF file format was developed primarily for scanner and desktop computer publishing software and is a storage format defined for storing black and white images, grayscale images, and color images. TIFF bitmaps can be of any size and resolution. The TIFF format encodes grayscale, CMYK mode, indexed color mode, or RGB mode. It can be saved in both compressed and uncompressed formats. The TIFF format is very versatile, and almost all applications that work with bitmaps can handle TIFF file formats. It can store alpha channels and store color separation data in a single file. If you want to print images, especially high quality images, the TIFF format is a more suitable choice.
The JPEG file format is the main format for compressed files in print. It is just a simple way to compress images without any more features. It uses a lossy compression format that makes it an ideal format for quickly displaying images and saving better resolution. Since some data is lost every time you save an image in JPEG format, you usually save the image in JPEG format only at the final stage of the creation.
