5-46 Managing Color in Adobe Photoshop

ES3640e MFP Color Reference Guide - 46

Saving files from Photoshop

Before saving a file from Photoshop, perform any necessary
rotating, cropping, and resizing. This speeds processing when
printing from the application in which the image is placed.

When saving a document from Photoshop 6.x, you have the
option to embed a color profile in the document. We recommend
that you disable this option if you are sending the document to
the Fiery.

Choosing a file format

We recommend that you use

file formats to save

images that will be imported into other documents and printed to
the Fiery. You can import EPS and TIFF files into virtually all page
layout applications.

Note:

Although TIFF files generally display better when imported

into other applications, their color and resolution characteristics
may be altered by the application into which they are imported.
EPS files are not modified by the application into which they are
imported.

Note:

In the following procedures, only Photoshop 7.x (Mac OS

version) dialog boxes are shown. When applicable, differences
between versions 7.x and 6.x, and the Windows and Mac OS
versions of Photoshop are noted.

To save a document from Photoshop

1. Choose Save As from the File menu.

The Save As dialog box appears.
