Photoshop’s default condition is to have many colour management options turned off. This is to make it as easy
as possible for rst time users to get to grips with the program. It is necessary however to activate many of these
colour management options so that Lyson printer proles are handled correctly. Also it should be said that the
more understanding of Photoshop’s colour management the user has, then the more predictable the printed result will be.
The following settings are not necessarily going to give the quickest and simplest work ow. They are designed so that the user
knows exactly what is happening at every stage of the le preparation and printing process. This ensures that the print looks as the
user would expect it to look.
Photoshop 5
Go to FILE-COLOR SETTINGS-PROFILE SETUP
Select “Ask When Opening” in all the drop down menus.
Tick the “Embed Proles” options at the top of the dialogue box.
The “Assumed Proles” options are the working spaces that Photoshop
assumes were used to create the images it is opening. The recommended
working spaces are given here:
RGB: Adobe RGB (1998)*
CMYK: US Web Coated (SWOP) V2
Greyscale: Greyscale - Gamma 1.8
At the top of this window ensure that all the Embed Prolesoptions are
ticked. This tags any images you create in Photoshop with the working
space that was in use at the time.
If an image is opened which does not have an embedded prole tag* then
the RGB, CMYK or Greyscale assumptions are applied.
Prole Mismatch Handling” dictates how Photoshop reacts when it opens
an image with an embedded prole* which does not match the working space currently in use. Setting these options to Ask When
Opening” allows the user to decide what to do in this event. The recommended choices are given later in this document.
Go to FILE-COLOR SETTINGS-RGB SETUP.
Select the working space you want to use from the RGB drop down menu. Leave the other options the same.
Ensure the “Display Using Monitor Compensation” box is ticked, as is the “Preview” box.
Next to Monitorat the bottom of the dialogue box will be the name of the monitor prole in use. If you have
proled your own monitor the prole name will appear here. For more information see the pdf document Monitor
Proles”.

Photoshop 6/7/CS
Go to EDIT-COLOR SETTINGS
These settings can be downloaded from the Lyson website as a document that can be imported directly into Photoshop. Download
the document from the Lyson website, ensure the document has been decoded correctly (Winzip for PCs, StuffIt! for Mac).
Go to the “Color Settings” section shown left.
Click on “Load”. Select the downloaded le and click “OK”.
All these settings will load automatically.
Alternatively, select your preferred working spaces from the
drop-down menus according to this screen shot. The settings
opposite are those that Lyson recommends.
Under “Working Spaces” select:
RGB: Adobe RGB (1998)*
CMYK: US Web Coated (SWOP) V2
Greyscale: Greyscale - Gamma 1.8
Spot: Dot Gain 20%
In Color Management Policies select Preserve Embedded
Proles” for “RGB”, “CMYK” and “Gray”.
This ensures that if an image is opened that was created in a different working space, the original colour information and working
space tag* is retained, rather than being converted automatically to the current working space. Remember that when an image is
“converted” from one working space to another then the colours in the image are altered. This is done so that the image after the
conversion resembles the way it appeared under the original working space. You may want to avoid this conversion under certain
circumstances. These circumstances are explained later in this document.
Also in “Color Management Policies” section tick “Ask When Opening” for Prole Mismatches”. Leaving the tick box blank for
the Missing Prolesoption ensures that any image without an embedded prole will open automatically in the working space
selected above.
Tick the “Advanced Mode” option at the top left of the Color Settings window.
Under “Conversion Options” select “Adobe(ACE)” as the Engine and “Relative Colormetric” as the “Intent”.
Ensure that “Black Point Compensation” is not ticked. Do not select any of the Advanced controls.
You can save these settings in case they need to be changed for some reason in the future. If you name the settings as “Lyson” then
they will be easily identiable later.

“Now I keep on getting these messages whenever I open a file”
If you are opening a le created before changing your colour settings, you may well see a message from Photoshop. The most likely
reason for this message is that your image has a different embedded RGB working space to the one now in use. The default RGB
working space when Photoshop is installed is sRGB. Lyson do not recommend this working space, see the pdf document “What are
Proles” to see why. However your images may well be carrying an sRGB tag, causing Photoshop to ask for your advice. Also, now
that Photoshop is recognising embedded proles you may be nding that les from your digital camera or scanner are carrying these
tags. The simplest approach under these circumstances is simply to convert the colours into your current working space.
Photoshop 5x
This is an example of the typical message that may appear. sRGB is the embedded
prole. RGB color is the standard term Photoshop 5 gives for the current RGB work-
ing space. Select Relative Colormetricas the rendering intent. Ensure Black Point
Compensation is not ticked.
Click “Convert
Photoshop 6/7/CS
This is an example of the typical message that may appear. sRGB is the embedded
prole. Adobe RGB (1998) is specied as the current RGB working space. Select the
middle option: Convert document’s colors to the working space”. The rendering
intent and black point compensation options for this conversion are the ones set in the
Color Settings” window explained earlier.
Exceptions to the rules.
Advanced users may wish to retain embedded proles so that nal edits can be made to an image without altering any colour data.
In these cases selecting the embedded prole instead of the working space (the top option in Photoshop 6/7/CS) will open the le
without changing the colours. This may often happen in print facilities where images require typographic changes or image editing
prior to a print run.
“Will this be required for every image I open?”
No. Once an image is saved under your new RGB working space then it will re-open straight way without any further messages.
Further information on proles can be found in the pdf document
