Photoshop Colour Settings
image_mode

All image files must be
Formatted in image mode 'RGB 8 bits per channel'

JPEG as in .jpg (baseline standard), Uncompressed (Photoshop Level 12) and saved as "Base Line Standard".

Colour settings: Working space should be "RGB: sRGB iec61966-2.1" and set your colour management policies "RGB: Convert to working RGB"

Color Settings

Photoshop Colour Settings

In photoshop, click on the <edit> menu, then click on <color settings>

In the drop down boxes choose the Working spaces as shown on the left.


In short setting in sRGB IEC61966-2.1 will result in less colour management problems. Our advice therefore is to set sRGB IEC61966-2.1 as default and forget it. (If you wish to learn more or are worried about using the sRGB colour space please click this link : http://www.kenrockwell.com/tech/adobe-rgb.htm )

Also we have found that using "Relative Colorametric" as your rendering intent will produce less colour errors and smoother colour transitions than Perceptual, especially in areas of high contrast.

Black Point compensation should be experimented with for personal preference. Some clients find having Black Point compensation OFF gives better control over black&white monochrome images.

Printer Profiles for Soft Proofing

For more precise colour matching, printer profiles can be used for Soft Proofing, prior to printing.
PLEASE NOTE: Do Not apply, assign to profile or Convert images to these profiles as the image will become double profiled, over saturated prints.Photoshop Colour Settings must remain as above in the previous step .

How to use and install Printer Profiles
Make a folder (eg DigitalWorks_Profiles) Click the required profile below and save to that folder.
Profile ImageTheta50 Profile for prints up to 20" (50.8cm) width and 5mtrs long
Profile ImagePrograph Profile for large format prints.
Locate the profile in the Folder you made, then Right Click the profile and choose < Install Profile >

How to set Adobe gamma with our calibration image

Shirley Calibration Image

The best way to set your monitor to match Digital Works print output is through using a monitor profiling tool, however these tools can be expensive.

For Mac users I highly recommend trying these two links
Mactalk Forum (problems calibrating Mac screens)
** Optimising Mac screens **

NB: To complete this calibration proceedure this printed image is required from Digital Works (Available with this image on CD. $5) You can also use an image previously printed through Digital Works of your own work.

(Adobe Gamma is no longer installed with Photoshop.)
We recommend using a typical image(s) (of your own work) and the monitors adjustments to adjust the monitor to your printed image previously printed through Digital Works.

Below is the proceedure for setting Adobe Gamma if you do have it.
Similar results can be achieved by using the monitors inbuilt adjustments or contact Adobe )
Location: for consistent results, your monitor should have no light or reflections hitting the screen.
Light from a window is probably the worst as the colour of daylight changes constantly.
LIGHTING: The room should be lit with Phillips TLD 95 fluoro tubes for colour correcting.
Allow monitor to warm up for about 20 minutes.

Now open the Calibration Image from the CD in photoshop(shown above).

1. Locate ‘Adobe Gamma’ which should be under [start] [settings] [control panel].
    (If it is not there you will have to use [search] [files & folders] Adobe Gamma.)
NB: Now is a good time to paste a Shortcut to Adobe Gamma onto your desktop.
Once in Adobe Gamma for the first time;
2. Use Step by Step (Wizard) click NEXT.

2b Load a monitor profile (if you have installed your monitor software, a profile for the monitor may be available in the profile list. If it is use it, otherwise use Adobe RGB 1998.icc)
(e.g. monitor profile may be placed under: C:\win\system32\spool\drivers\color)
click OPEN. (description should now be what you just chose as your monitor profile)
click NEXT
2c Follow instructions on this panel for Contrast and Brightness.
Click NEXT when ready
2d  In the drop down box choose ‘Trinitron’ if your monitor is Trinitron type
( for best results your monitor should be a Trinitron type tube.)
Click NEXT
2e Uncheck the box ‘View Single Gamma Only’ and, RED GREEN & BLUE boxes should appear with sliders below each.
With our Calibration Image on your screen, adjust each colour (if necessary) to match the supplied print. (Click on the slider then use the arrow keys on your keyboard for finer adjustments)The grey scale should end up looking clean, and skin tones should be very close to the supplied image.
When satisfied, click NEXT
2fSet Hardware White Point to 6500 K (daylight) or use measure if not sure.
Click NEXT    Click NEXT
2g The After ‘radio button’ should be checked
Click FINISH
In the drop down text box type a name to easily identify your profile,
e.g. “SPRINTZ Profile”
Click SAVE and it’s done.
Do any final BRIGHTNESS & CONTRAST changes at the monitor.
Now have a break for 5 or 10.
Recheck the colour etc of our Calibration Image. If not happy bring up Adobe Gamma again click the ‘Control Panel’ radio button then next and adjust as you see fit. (THIS MAY TAKE SEVERAL TRIES UNTILL YOU ARE COMFORTABLE. Be patient.

Will this mean all your prints will match perfectly? …..probably not, ……But you’ll be close.
