Specific features and options may vary, depending on the Color Server model at your site. N OTE : The term "printer" is used throughout this manual to denote a supported printer or copier; the term "toner" refers to either toner or ink. About this manual This manual provides an overview of general color concepts, with a specific focus on color management for print output. [. . . ] · Do not select the PostScript Color Management option. For more information about PostScript Color Management, see the following section. · Do not select Include Transfer Function or Include Halftone Screen. NOTE: If you choose JPEG encoding, save a backup of the original image saved with binary encoding until you see the printed results of the JPEG file. Occasionally, the compression used for JPEG encoding produces unwanted artifacts. If you see unexpected results in the printed output of a JPEG file, revert to a binary version. If you experience problems printing the document in which you placed the image, substitute an ASCII version of the same image and reprint the document. Binary encoding is much more compact than ASCII encoding, but occasionally causes printing problems with some system configurations. MANAGING COLOR IN ADOBE PHOTOSHOP 39 Selecting options when printing You can print RGB or CMYK images from Photoshop. · When you print an RGB image, you choose whether the conversion to CMYK is performed by the Color Server (using a CRD), PostScript (using PostScript Color Management), or Photoshop built-in color management. · When you print a CMYK graphic, you can print composites or color separations. NOTE: Make sure that the Color Server Combine Separations print option is set to Off. To print separations, use the Separation option in the Photoshop pane of the print dialog box. For instructions, see your Photoshop documentation. TO PRINT IMAGES FROM PHOTOSHOP 7. X 1 Choose Print with Preview from the File menu. The Print dialog box appears. 2 Select Show More Options. 4 Choose an Encoding method. NOTE: If you choose JPEG encoding, save a backup of the original image with binary encoding until you see the printed results of the JPEG file. Occasionally, the compression used for JPEG encoding produces unwanted artifacts. If you see unexpected results in the printed output of a JPEG file, revert to the binary version. MANAGING COLOR IN ADOBE PHOTOSHOP 40 5 Select Color Management. 6 Choose Same as Source from the Profile menu to specify the color space for printing the image. Any other setting causes Photoshop to convert image data to that color space before sending it to the Color Server. 7 Click Print. TO PRINT IMAGES FROM PHOTOSHOP 6. X 1 Choose Print from the File menu. The Print dialog box appears. MANAGING COLOR IN ADOBE PHOTOSHOP 41 2 Choose the Color Server from the Printer menu, and then choose Adobe Photoshop from the menu beneath the Printer menu. 3 Choose an Encoding method. NOTE: If you choose JPEG encoding, save a backup of the original image with binary encoding until you see the printed results of the JPEG file. Occasionally, the compression used for JPEG encoding produces unwanted artifacts. If you see unexpected results in the printed output of a JPEG file, revert to the binary version. 4 Choose Same as Source from the Profile menu to specify the color space for printing the image. Any other setting causes Photoshop to convert image data to that color space before sending it to the Color Server. 5 Click Print. Advanced tips for using PostScript color management Use the following information to implement alternative, more complex, color workflows with Photoshop. NOTE: To use PostScript color management with Photoshop 6. x, choose PostScript Color Management from the Profile menu in the Photoshop pane of the printer driver. Saving EPS documents with PostScript Color Management Selecting the PostScript Color Management option when saving either a CMYK or RGB EPS file prompts Photoshop to embed PostScript color information--which is independent of ICC profiles--in the resulting document. This information is intended for PostScript devices like the Color Server. Printing RGB EPS files saved with PostScript Color Management When you print an RGB EPS file that contains an embedded profile to the Color Server, you can use the working space information from the embedded RGB profile as an RGB source definition for Color Server CRDs. To use this source color space information from the embedded profile with Color Server CRDs, choose None as the ColorWise RGB Source when you print. [. . . ] However, high-resolution files can be large and, therefore, cumbersome to transmit over a network, process for printing, store on disk, and edit. Beyond a certain threshold, a higher image resolution greatly increases file size while having a minimal effect on output quality. The optimal image resolution depends on the resolution of the final print device. Aim for the resolution that optimizes both file size and output quality. [. . . ]
