saving the image for four-color printing


Before you save a Photoshop file for use in a four-color publication, you must
change the image to CMYK color mode. You’ll use the Mode command to change
the image color mode.

For more information about converting between color modes, see Photoshop Help.
1  Choose File > Save As, and save the file as 02_CMYK.psd. Click OK if you see a
    Photoshop Format Options dialog box.

 It’s a good idea to save a copy of your original file before changing color modes, so
that you can make changes in the original later, if necessary.

2  Choose Image > Mode > CMYK Color. Click OK when Photoshop displays an
    alert about the color management profile.

If you were preparing this image for a real publication, you’d want to confirm that
you were using the appropriate CMYK profile. See Lesson 14, “Producing and
Printing Consistent Color,” to learn about color management.


3 If you use Adobe InDesign to create

your publications, simply choose
File > Save. InDesign can import
native Photoshop (PSD) files, so
there is no need to convert the
image to TIFF.

If you’re using another layout
application, choose File > Save As,
and then proceed to step 4 to save
the image as a TIFF file.

4  In the Save As dialog box, choose
    TIFF from the Format menu.
5  Click Save.
6  In the TIFF Options dialog box,
    select your operating system for the
    Byte Order, and click OK.
The image is now fully retouched, saved, and ready for placement in a page
layout application.
For more information about file formats, see Photoshop Help.

You can combine Photoshop images with other

elements in a layout application such as

Adobe InDesign.

review answers

1  The term resolution refers to the number of pixels that describe an image and establish

    its detail. Image resolution and monitor resolution are measured in pixels per inch (ppi).

    Printer, or output, resolution is measured in ink dots per inch (dpi).

2  You can use the Crop tool to trim, scale, or straighten an image.

3  Use the White Balance tool to adjust the color temperature. Then fine-tune the color

    and tone using sliders in the Basic panel.

4  The Healing Brush, Spot Healing Brush, Patch tool, and Clone Stamp tools, as well as

    content-aware fill, let you replace unwanted portions of an image with other areas of

    the image. The Clone Stamp tool copies the source area exactly; the Healing Brush

    and Spot Healing Brush tools blend the area with the surrounding pixels. The Spot

    Healing Brush tool doesn’t require a source area at all; it “heals” areas to match the

    surrounding pixels. The Patch tool in Content-Aware mode, and content-aware fill

    replace a selection with content that matches the surrounding area.

5  The Unsharp Mask filter adjusts the contrast of the edge detail and creates the illusion

    of a more focused image.
