You can choose colors in Photoshop with various color models including HSB, CIE 
Lab, RGB, and CMYK. You can also choose named colors from the PANTONE 
Coated color library. For best results, use the color definition methods described in 
Chapter 5.

For images you scan on the copier using the Fiery Scan acquire module, use Photoshop 
5.x’s Profile to Profile function to convert the RGB data from the copier’s RGB color 
space to your chosen Photoshop RGB working space. The User CD includes a scanner 
profile to be used as the source when making this conversion. For an explanation of 
this procedure, see Getting Started.

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

It is recommended that you use EPS or TIFF file formats to save RGB images that will 
be imported into other documents and printed to the Fiery X4. You can import EPS 
and TIFF files into virtually all page layout applications.

Although TIFF files display better when imported into other applications, their 

color and resolution characteristics may be altered by the application into which they 
were imported. EPS files are left untouched.
