Color Managed Workflow with ICC Profiled Output
Now your can have your images printed exactly how you "soft-proof" them on your computer screen. Printroom's
proprietary preprint software recognizes color space you used to create and edit an image, such as
sRGB IEC61966-2.1, Adobe RGB (1998), ColorMatch RGB or even an embedded custom profile.
We use the color information in your image file to convert it to the color space of the printer used to print the particular
size-paper combination specified in the order. As a result, the images are printed exactly how you see them
on your calibrated monitor in a "color aware" program like Adobe Photoshop.
Since our process supports embedded profiles YOU DO NOT NEED TO CONVERT the image to the Printroom.icc color space before
sending it to us - this will only increase your image file size by about 700KBytes.
The color managed workflow is always enabled unless you select autocorrect when placing your order. Also, we assume
sRGB profile for images containing no color space information. All photos are printed on Fuji Crystal Archive paper.
To calibrate your monitor you can use hardware tools like ColorVision Spyder, MonacoOPTIX, or Gretag Macbeth Eye-One.
Or, you can rely on your own color matching abilities and go for a software calibration with something like
Adobe Gamma. If you are using Adobe Photoshop on Windows or MacOS, use the Adobe Gamma Control Panel, which
is automatically installed with the program. Do not use Adobe Gamma if you are working on the Macintosh and
have already run the ColorSync Calibration Assistant.
Soft Proofing using Printroom.icc profile
The fact of the matter is that some colors on the edge of the gamut are not reproducible by the printers.
As a photographer you can check for and correct the "out of gamut" conditions by soft proofing the image
with the provided Printroom.icc profile. Here is how:
Click here to download Printroom ICC Profile, and save it to proper location.
Win98, Win98SE, WinMe - C:\Windows\System\Color
Win XP - C:\Windows\System32\Spool\Drivers\Color
Windows NT, Win 2000 - C:\WinNT\System32\Spool\Drivers\Color
Mac OS 9.x - System Folder>ColorSync Profiles
Mac OS X - Library>ColorSync>ColorSync Profiles
(If the ICC files are not in any of these folders on your computer you can find
the correct folder by searching your computer for *.icc.)
When in Adobe PhotoShop do the following:
Go to View>ProofSetup>Custom...
Do not select Preserve Color Numbers (leave the box unchecked)
Select Use Black Point Compensation
At this point you can name and Save this proof setup for future use.
You can view and edit the image while in the "proof" mode and see immediately
how your corrections will be reflected in the final print.
Advantages of the Printroom Workflow
Printroom, unlike other labs, supports embedded profiles, so you will not have to convert you file to our printer profile
before sending it to us. As long as your image has an embedded profile - either for a standard color space like sRGB,
Adobe RGB 1998, etc or a custom one, such as your camera profile we can interpret it and do the conversion on our end.
The main benefits of this approach are:
a. You have fewer file preparation steps and no duplicate files to keep track of on your end.
b. Printers we use have very similar gamut even with different paper types. This means that you can use the same
profile to soft proof your images regardless of the paper and printer used for the final output. However, each
printer is always calibrated for a particular paper type (glossy, matte, or pro lustre) and interprets colors differently
(has a different B to A table - different profiles for different paper types). We automatically convert image
files to the correct color space using the latest profiles for each paper type/printer combination.
c. We periodically (every couple of weeks) re-profile the printers to adjust for changes in operating conditions,
variations in paper emulsion, chemistry, etc. We always use the latest profiles in our preprint processing.
Another benefit of this approach is that we need to publish (and you need to download) new profiles for soft
proofing rather infrequently - only when there are changes affecting printer gamut, usually when switching to a
new type or brand of paper.
