PHOTOSHOP CS3 455 User Guide Include Vector Data Preserves any vector graphics (such as shapes and type) in the file. However, vector data in EPS and DCS files is available only to other applications; vector data is rasterized if you reopen the file in Photoshop. This option is only available if your file contains vector data. Image Interpolation Applies anti-aliasing to the printed low-resolution image. See also "Photoshop EPS format" on page 460 Photoshop EPS encoding options ASCII or ASCII85 Encodes if you're printing from a Windows system, or if you're experience printing errors or other difficulties. Binary Produces a smaller file and leaves the original data intact. However, some page-layout applications and some commercial print spooling and network printing software may not support binary Photoshop EPS files. JPEG Compresses the file by discarding some image data. You can choose the amount of JPEG compression from very little (JPEG Maximum Quality) to a lot (JPEG Low Quality). Files with JPEG encoding can be printed only on Level 2 (or later) PostScript printers and may not separate into individual plates. Save a file in Photoshop DCS format DCS (Desktop Color Separations) format is a version of EPS that lets you save color separations of CMYK or multichannel files. 1 Choose File > Save As, and choose Photoshop DCS 1.0 or Photoshop DCS 2.0 from the Format menu. 2 In the DCS Format dialog box, select the options you want, and click OK. The dialog box includes all the options available for Photoshop EPS files. Additionally, the DCS menu gives you the option of creating a 72-ppi composite file that can be placed in a page-layout application or used to proof the image: DCS 1.0 format Creates one file for each color channel in a CMYK image. You can also create a fifth file: a grayscale or color composite. To view the composite file, you must keep all five files in the same folder. DCS 2.0 format Retains spot color channels in the image. You can save the color channels as multiple files (as for DCS 1.0) or as a single file. The single-file option saves disk space. You can also include a grayscale or color composite. See also "Photoshop DCS 1.0 and 2.0 formats" on page 460 Save a file in Photoshop Raw format The Photoshop Raw format is a file format for transferring images between applications and computer platforms. The Photoshop Raw format is not the same as camera raw. 1 Choose File > Save As, and choose Photoshop Raw from the Format menu. 2 In the Photoshop Raw Options dialog box, do the following: • (Mac OS) Specify values for File Type and File Creator, or accept the default values. • Specify a Header parameter. • Select whether to save the channels in an interleaved or noninterleaved order.
