In this chapter, you’ll learn how to save and prepare les for export to other programs for print output, and for viewing online. Preparing Photoshop files for other applications Photoshop to Adobe InDesign Photoshop PSD les can be imported directly into Adobe InDesign. Photoshop layers (and layer comps) are preserved, and you can turn their visibility on or o in InDesign. InDesign can separate Photoshop PSD and PDF les (RGB or CMYK), and can read ICC color proles that are embedded in Photoshop les. And because it’s part of the Adobe Creative Suite, InDesign lets you use Bridge for le and color management. Alpha channels, layer masks, and transparency are also preserved, eliminating any need to use clipping masks. If you want to import only part of a Photoshop layer into InDesign CS5, you can use either a layer mask or an alpha channel. In Photoshop, select an area of a layer, then create a layer mask or an alpha channel (if you haven’t already done so). In InDesign, choose File > Place, and in that dialog, check Show Import Options. e Image Import Options dialog opens. For a mask, under Show Layers, show the layer that contains the layer mask and hide any other layers; for a channel, click the Image tab, then from the Alpha Channel menu, choose the alpha channel (the alpha channel will clip all layers). Click OK. Photoshop to QuarkXPress To color-separate a Photoshop image from Quark - XPress, you can convert it to CMYK Color mode before importing it into Quark XPress, or you can let Quark XPress read the embedded proles and convert your RGB TIFF into a CMYK TIFF. Ask your output service provider which program to use for the con- version. With the PSD Import XTension installed, layered PSD les can be imported into QuarkXPress 6.5 and later. In QuarkXPress, you can adjust the layer blending mode and opacity. If the PSD le contains layer eects or has a higher color depth than 8 bits per channel, all layers will be attened upon import. Continued on the following page ptg 416 Chapter 26 If you need to place only a portion of a Photoshop image into QuarkXpress 7 or 8, select an area of a layer, then create an alpha channel. In QuarkXPress, import the le using File > Import Picture. Controls for choosing and modifying the alpha channel can be found on the Measurements palette. Photoshop to Adobe Illustrator Not surprisingly, les from Photoshop CS5 and Adobe Illustrator CS5 are compatible in many (although not all) respects. ➤ If you drag and drop a Photoshop selection or layer into Illustrator, the imagery will appear on the Layers panel in Illustrator as an image layer in Windows, or as a group with an image layer in the Mac OS. Opacity settings are reset to 100% but are preserved visually, the blend- ing mode is reset to Normal, and layer and vector masks are applied to their respective layers. All transparent areas are lled with white. ➤ If you copy and paste a layer from Photoshop into Illustrator, layer masks are discarded without being applied. ➤ Via File > Place, you can place either a whole Photoshop image or just a single layer comp into Illustrator. If you place a Photoshop image with the Link option checked, the image will appear on the Layers panel on a single image layer, and any masks will be applied. If you embed the Photoshop image as you place it (uncheck the Link option), you’ll have the option via the Photoshop Import Options dialog to convert layers into objects or atten them into one layer. is choice is also available if you open a Photoshop image via File > Open in Illustrator. Using the Place or Open command, if you decide to convert layers into objects, each layer will appear as an object on its own editable nested layer within a group. e Background (if any) will become a separate, opaque layer. All transparency values are preserved, and blend- ing modes that are also available in Illustrator are preserved; both are listed as editable appearances in Illustrator. (To verify which blending modes are available in Illustrator, click the blending mode menu on the Transparency panel.) Layer masks become opacity masks. Layer eects are applied to the layer; their visual eects are preserved. We prefer the Convert Layers to Objects option because it preserves layer transparency. In the Photoshop Import Options dialog, you can check Import Hidden Layers if you want to allow hidden layers to be imported. ➤ e presence of adjustment layers in a Photoshop document will prevent underlying Photoshop layers from becoming individual layers in Illustrator. To work around this limitation, hide the adjustment layers, or merge the adjustment layers downward. Save the Photoshop le, then open or place it into Illustrator. ➤ If you decide to atten Photoshop layers into one layer, the eect of all transparency, blend- ing modes, and layer masks will be preserved visually, but won’t be editable in Illustrator. ➤ When you open or place a TIFF, EPS, or PSD le into Illustrator, the le resolution stays the same, but the Photoshop image adopts the color mode of the Illustrator le. Via the Eect menu in Illustrator, some Photoshop (raster) eects and some Illustrator (vector) eects can be applied to the imported images. MAKING FILES COMPATIBLE When you open a Photoshop (PSD) fi le in another application, ideally that target application should be able to read layers. To allow your PSD fi les to be readable by those that don’t, go to Edit/Photoshop > Preferences > File Handling and from the Maximize PSD and PSB File Compatibility menu, choose Always. To apply the preference change, reopen and resave the layered PSD fi les. A composite preview will be saved with the layered version for applications that don’t support layers, and a rasterized copy of any vector art will be saved for applications that don’t support vector data. Although this option produces larger fi les that take longer to save, it’s an accept- able trade-off for the needed compatibility. ptg Export 417 Saving a file in the TIFF format TIFF les are versatile in that they can be imported into most applications and are usable in many color management scenarios. Both InDesign and QuarkXPress can color-separate a CMYK color TIFF. Note that although Photoshop les up to 4 GB can be saved in this format, 2 GB is the largest le size that other applications can read. To save a file in the TIFF format: 1. Optional: If your commercial printer requests that you convert the color mode of your document to CMYK, choose Image > Mode > CMYK Color. 2. Choose File > Save As, enter a name or keep the current name, choose Format: TIFF, and choose a location for the le. 3. In the Save area: Check Save a Copy to keep the existing le open onscreen and save a copy of it to disk. Check Layers to preserve any layers in your le. Note, however, that few image or layout pro- grams can work with layered TIFFs, and those that don’t will either atten the layers or ignore the layer data. We recommend unchecking this option to allow the le to be attened. You can also choose to save Alpha Channels, Notes, or Spot Colors, if the le contains them. 4. Optional: Check ICC Prole/Embed Color Prole to include the currently embedded color prole with the le. For more about color management, see Chapter 1. 5. Click Save. e TIFF Options dialog opens. A 6. If you need to reduce the storage size of the le, choose an Image Compression method. e LZW and ZIP methods are nonlossy. Some programs can’t open TIFF les that are saved with ZIP compression, so nd out which le format your target application supports. We don’t recommend choosing the JPEG compression option because it discards some image data. Note that for color separation, output service providers prefer uncompressed les, in which case you should click None. Leave the Pixel Order on the default setting of Interleaved (RGBRGB). A  i s i s t h e T I F F O p t i o n s d i a l o g i n t h e M a c O S . Click Byte Order: IBM PC or Macintosh, for the platform the le will be used on. Optional: Check Save Image Pyramid to save multiple resolutions of the image in one le. Photoshop doesn’t oer options for opening image pyramids, but Adobe InDesign does. If your le contains transparency and you want it to be preserved, check Save Transparency. To access this option, the bottommost layer in the le must be a layer — not the Background. If the le contains layers, click a Layer Compression method. 7. Click OK. ptg 418 Chapter 26 Saving a file in the EPS format If the drawing or page layout program you’re plan- ning to export your les to can’t read Photoshop PSD or PDF les, the Photoshop EPS format is the next best option. Note that this format attens layers and discards alpha channels and spot chan- nels. To access it, your le can be in any color mode except Multichannel, but its color depth must be 8 bits per channel. Printing an EPS le requires using a PostScript or PostScript-emulation printer. To save a file in the EPS format: 1. Optional: If the le is to be color-separated by another application and you want to see a simulation of how it will look when converted to CMYK mode, choose View > Proof Setup > Working CMYK. 2. Choose File > Save As (Ctrl-Shift-S/Cmd-Shift-S) to open the Save As dialog. 3. Enter a le name or keep the current name, choose Format: Photoshop EPS, and choose a location in which to save the le. Optional: Check ICC Prole/Embed Color Prole to have Photoshop embed the document color prole or current working color space into the le (see pages 10 and 16). Click Save. Note that all layers will be attened. e EPS Options dialog opens. A–B 4. From the Preview menu, choose TIFF (1 bit/ pixel) to save the le with a black-and-white preview or TIFF (8 bits/pixel) to save it with a grayscale or color preview. Mac OS users, choose a Macintosh preview only if you’re certain you won’t need to open the le on another platform. 5. If the le is to be used in the Mac OS, choose Encoding: Binary, the default method used by PostScript printers. Binary-encoded les are smaller and process more quickly than ASCII les. If the le is to be used in Windows, or for applications, PostScript printers, or printing utilities that can’t handle binary les, you must choose ASCII85 or ASCII. JPEG is the fastest encoding method, but it causes some data loss. A JPEG le can be printed only on a PostScript printer that is Level 2 or higher. Note: e PostScript Color Management Option converts the le’s color data to the printer’s color space. Don’t choose this option if you’re going to import the le into another color-managed A In the EPS Options dialog in Windows, choose Preview and Encoding options. B In the EPS Options dialog in the Mac OS, choose Preview and Encoding options. ptg Export 419 application (such as InDesign), as unpredictable color shifts may result. 6. If your document contains vector elements, such as shapes or type, check Include Vector Data. Although saved vector data in EPS les is available to other applications, as an alert will tell you if you reopen the le in Photoshop, that data will be rasterized. 7. For low-resolution output only, check Image Interpolation to allow other applications to resample the image pixels, to help reduce jagged edges. 8. Click OK. To quickly save multiple files in the JPEG, PSD, or TIFF format: 1. In Bridge or Mini Bridge, click a folder, then select the thumbnails for multiple PSD or JPEG les or raw photos. 2. Choose Tools > Photoshop > Image Processor. e Image Processor dialog opens. A 3. Optional: If you selected raw photos, check Open First Image to Apply Settings to have the Camera Raw dialog open for the rst selected photo, enabling you to choose settings. Check this option only if you’re certain the other raw photos you have selected need the same adjustments. 4. To choose a location for the new les, do either of the following: Click Save in Same Location. Click Select Folder, navigate to the desired location, then click Open. 5. Click the desired File Type (or types) and applicable settings. 6. Optional: Enter Copyright Info (such as your name) to be added to the les’ metadata. 7. Check Include ICC Profile to include the le’s color prole so its display and output can be color-managed. 8. Click Run. If a le opens into Camera Raw, choose settings, then click Open Image. After the les are done processing, a folder contain- ing the new les and bearing the name of the le format appears in the designated location. ➤ Via the Save button, you can save the current settings as a preset. en, to apply it to other images, use the Load button. CREATING A COMPRESSED ZIP FILE To reduce the storage size of a fi le without discarding any of its data, you can create a compressed version of it, using the ZIP compression command that’s built into your system: ➤ To create a ZIP fi le in Windows, right-click a fi le and choose Send To > Compressed (Zipped) Folder from the context menu. A compressed version of the fi l e w i l l a p p e a r i n a n e w f o l d e r w i t h i n t h e c u r r e n t folder. ➤ To create a ZIP fi le in the Mac OS, right-click a fi l e n a m e i n t h e F i n d e r a n d c h o o s e Compress [fi le name] from the context menu. A Use the Image Processor command to quickly save multiple les in the JPEG, PSD, or TIFF format. ptg 420 Chapter 26 PDF (Portable Document Format) les can be opened in many Windows and Macintosh applica- tions, as well as in Adobe Reader, Acrobat Standard, and Acrobat Professional. 8-bit and 16-bit les (not 32-bit les) in any color mode except Multichannel can be saved in this format. Photoshop will create one of two kinds of PDF les, depending on which preset you choose in the Save Adobe PDF dialog. e default PDF format, Photoshop PDF, preserves image, font, layer, and vector data, but it can save only one image per le. To create a Photoshop PDF le, you need to check Preserve Photoshop Editing Capabilities in the Save Adobe PDF dialog. is type of PDF can be opened only in Photoshop CS2 and later. (To save multiple images in one PDF le, see “Creating a PDF Presentation” on pages 380–381.) Photoshop can also create generic PDF les, which are similar in format to PDFs from a graphics or page layout application. To save a Photoshop image as a generic PDF le, uncheck the above-mentioned Preserve Photoshop Editing Capabilities option. e image will be attened and rasterized, so your ability to re-edit it in Photoshop will be very limited. To save a file in the PDF format: 1. Choose File > Save As, enter a le name or keep the current name in the File Name/Save As field, choose a location in which to save the file, choose Format: Photoshop PDF, then click Save. If an alert dialog appears, click OK. e Save Adobe PDF dialog opens. A 2. From the Adobe PDF Preset menu, choose one of the predefined settings, depending on the output medium (press, Internet, etc.). e High Quality Print and Press Quality presets create a large Photoshop PDF le that is compatible with Adobe Acrobat 5 and later, compress the le using JPEG at Maximum quality, embed all fonts automatically, and preserve transparency. Note: For commercial printing, ask your shop what settings to use. e Preserve Photoshop Editing Capabilities option is selected for both presets, by default: High Quality Print (the default preset) creates PDF files for desktop printers and color proong devices. e le won’t be PDF/X-compliant. e color conversion is handled by the printer driver. Press Quality is designed for high-quality pre- press output. Colors are converted to CMYK. Preserve Photoshop Editing Capabilities is unchecked for the PDF/X and Smallest File Size presets, so they produce generic PDF les: PDF/X-1a:2001, PDF/X-3:2002, and PDF/X-4: 2008 create PDF files that will be checked for compliance with specic printing standards, to help prevent printing errors. e resulting files are compatible with Acrobat 4 and later; PDF/X-4 les are also compatible with Acrobat 5 and later. Smallest File Size uses high levels of JPEG com- pression to produce very compact PDF files for output to the Web, transmission via e-mail, etc. All colors are converted to sRGB. 3. Click Save PDF, then click Yes in the alert dialog. ➤ To learn more about the PDF format, see “Saving PDF Files” in Photoshop Help.
