5. In the bottom half of the dialog box, uncheck the Layers option.
Because this file contains layers, the Layers
option is checked by default.

The As a Copy box is now selected by

overwriting your layered file with a flattened
version.) Uncheck this option.
If your file contained alpha channels,
annotations, or spot colors, those check
boxes would also be available.

6. Leave the remaining options at their default values and click Save.

7. In the resulting TIFF Options dialog box, make sure the None image
compression option is selected.
TIFF files can be compressed (made smaller) using three methods:
• None (as the name implies) applies no compression to the
file. This option is safe if file size is not an issue, but digital file
transmission often requires files to be smaller than a full-page,
multi-layered Photoshop file.
• LZW (Lempel-Ziv-Welch) compression is lossless, which means
all file data is maintained in the compressed file.
• ZIP compression is also lossless, but is not supported by all desktop-publishing
software (especially older versions).
• JPEG is a lossy compression scheme, which means some data will be thrown
away to reduce the file size. If you choose JPEG compression, the Quality options
determine how much data can be discarded. Maximum quality means less data
is thrown out and the file is larger. Minimum quality discards the most data and
results in a smaller file size.

8. Leave the Pixel Order radio button at the default value, and choose the
Byte Order option for your operating system.

Pixel Order determines how channel data is encoded. The Interleaved (RGBRGB)
option is the default; Per Channel (RRGGBB) is called “planar” order.
Note:
Byte Order determines which platform can use the file, although this is somewhat
deceptive. On older versions of most desktop-publishing software, Macintosh systems Some experts argue that

If your file contains transparency, the Save Transparency check box will be available. If
you don’t choose this option, transparent areas will be white in the saved file.

9. In the Layer Compression area, make sure the Discard option is selected.
These three options explain — right in the dialog box — what they do.

10. Click OK to save the file, then continue to the next exercise.
