printer using the Convert to Profile command in two steps. These color
space conversions would be applied to the open document. Using Proof ,
this all can happen in one location while leaving the original document
untouched. The Proof conversions happens in this order:
1. ColorMatch RGB (relative colorimetric, as selected in Proof Setup )
to CMYK (for press).
2. CMYK (for press) (absolute colorimetric, selected in Print with
Review ) to RGB for Epson.
In other words, a three-way conversion takes place to show you what
the CMYK should eventually look like using your Epson starting with the
document in ColorMatch RGB. When the Proof radio button is on, this
tells Photoshop to convert from working space to this proof space and
then to the final print/output space selected from the Profile pop-up
menu. The rendering intent selected and saved in a current Proof Setup is
used for the conversion from the document color space to this proof color
space. The rendering intent selected in the Print with Preview dialog is used
for the conversion from the proof color space to the final printer color
space. If you do not intend to make this kind of three-way conversion,
be careful that the Proof radio button is not selected.
Print Space The pop-up menu named Profile in the Print Space area of the
dialog is where you can select the output profile you wish to use for the
color space conversion. Just like the Convert to Profile command, all you
have to do is select the ICC profile you wish to use. There is one setting
in the top of this list called Same as Source . What this setting does is effec-
tively turn off the output profile from being used. That is, if Same as Source
is selected, the data is sent directly to the printer without any profile con-
version being applied. This can be useful in situations where you may
have already converted the file to the print/output space using the Convert
to Profile command but still want to use other options in this Print with
Preview command. The Source Space / Document area at the top of this dialog
is a good reminder for ensuring that the color space of the document
about to be printed is not in a print/output space. If the image were in
Epson 2200 Matt output space and the Print Space was set to anything
but Same as Source , Photoshop would convert the data again resulting in
very poor color output. In essence, you would be conducting double color
management. So, keep an eye on both these pop-up menus. Same as
Source is also the setting you should use to print out targets for building
output profiles since the aim is to send those documents to the printer
as is without color management.
The option in this Profile pop-up menu called Printer Color Management
(or in the case of a Postscript printer, named Postscript Color Management )
operates much like Same as Source but sends the source data and the
embedded profile to the printer in such a case that the printer has
the ability to convert to the print/output space. This could be used in
