Color Management 101, Part III: Soft-Proofing in Photoshop

This is the 3rd of 3 posts on implementing proper Color Management into your Photoshop workflow. In the first post, I discussed the Four Steps to Successful Color Management as well as how to properly Profile your Monitor. In the second post, I talked about Printer Profiles.

Now let’s talk about Soft-Proofing

By the way, these three posts are basically one chapter of 35 chapters from my E-Book, “Photofinishing with Photoshop” - If you like what you see in these posts, you should consider purchasing my E-Book here.

Step 3 - Soft-Proof Your Image in Photoshop

The purpose of Soft Proofing is a previewing procedure that Photoshop uses to “see” the results of your Printer Profile. In other words, it allows you to view on your calibrated and profiled monitor what your image will look like when it is printed (using your Printer Profile). This is truly WYSIWYG – What You See Is What You Get!

How it Works:

  1. Go to “View” → “Proof Setup” → “Custom”
  2. Go to “Device to Simulate” and select your new paper profile from the drop-down list.
  3. Rendering Intent should be “Relative Colorimetric” and “Black Point Compensation” should be checked.
  4. Leave both “Display Options (On-Screen)” unchecked.
  5. Click “OK”.
  • You can toggle this soft proof on and off by going to “View” → “Proof Colors” or by using the speed key: Mac: “Command’ + “Y” or Windows: “Control” + “Y”.
  • Soft Proofing is active when the profile name shows up in the Document Window’s title bar.
  • You can save this soft proof setup by clicking on the “Save” button. The saved name will now show up in the list, “View” → “Proof Setup”.

Gamut Warning:

A Gamut is the range of colors that a color system can display or print. If your image has an “out-of-gamut” color, that color will not print as it is shown on your monitor.

  • To set up the gamut warning: You should first choose a bright fluorescent color to show your out-of-gamut colors when the warning is active, such as Lime Green. To do this, go to “Preferences” (“Command”+ “K” on Mac, “Control” + “K” on Windows) → “Transparency & Gamut” (From the menu on the left) → “Gamut Warning” (double–click on the color box, and change to something like RGB 255/0/255 in the Color Picker).
  • To Check Gamut: Make sure that you are Soft-Proofing (A printer profile must be loaded), then go to “View” → “Gamut Warning”. The areas that are out-of-gamut will show up as the fluorescent color you picked above.
  • To Correct: Use a “Hue/Saturation” adjustment layer to correct the out-of-gamut color until the fluorescent color disappears. You can do this either globally or locally with selection tools.
  • To Turn Off Gamut Warning: Go to “View” →“Gamut Warning” and click it again. If you prefer, you can use the available speed key shown by the menu item.

Color Management 101, Part II: Printer Profiles in Photoshop

This is the 2nd of 3 posts on implementing proper Color Management into your Photoshop workflow. In the last post, we discussed the Four Steps to Successful Color Management as well as how to properly Profile your Monitor.

Now let’s talk about Printer Profiles

By the way, these three posts are basically one chapter of 35 chapters from my E-Book, “Photofinishing with Photoshop” - If you like what you see in these posts, you should consider purchasing my E-Book here.

Step 2) Use the Proper Printer Profile or Create a Custom Printer Profile

A Printer Profile makes the most out of your printer’s capabilities by characterizing the behavior of your printer/ink/paper combination. With a Printer Profile, in combination with the other elements of Color Management, you will significantly improve the accuracy and quality of your print output.

There are 3 choices for Printer Profiles:

1) Use Printer Profiles provide by your Custom Print Lab - Most good print labs implement Custom Printer Profiles into their workflow, and will be glad to supply them to you. By following the 4 steps to Color Management listed above, and setting up your file the way the lab likes it, you can achieve excellent results without ever physically visiting the lab. You might also realize some cost savings, as most of these labs will give you a discount for setting up your files ahead of time.

2) Use Canned” Printer Profiles for your Inkjet Printer – If you cannot afford a Custom Printer Profile, these generic Printer Profiles are available from the manufacturer of your printer or paper. Although using one is better than no profile at all, they are not as accurate as a well-built custom profile, which will bring out the best in your printer. The reason for this is that a generic profile is based on an “average” – not your specific printer.

3) Use Custom Printer Profiles for your Inkjet Printer - If you’ve never bothered with custom printer profiles because you thought it was too complicated or expensive, it is easier and more affordable than you think, and the results in your print output will be dramatic!

Why? Because all printers, even amongst the same make and model #’s, are different, and these profiles are designed specifically for your printer. Watts Digital Imaging can create your Custom Printer Profile(s) for you for $40 each. See my website for more information.

  • You will need one Printer Profile for each paper/ink/printer/resolution combination that you print on.
  • Unlike a Monitor Profile, a Printer Profile will not “drift” appreciably unless you change printers, ink type / brands, paper type / brands, or introduce any other variable. For all practical purposes, they are good for a few years.

To Create a Custom Printer Profile for your Inkjet Printer: (This varies between Profiling Services)

  1. Download Profile Target(s) and instructions.
  2. Print the Profile target onto the paper to be profiled with all Color Management “Off”.
  3. Mail the Profile Target to the profiling service.
  4. The target is measured using a Spectrophotometer, and a profile is created.
  5. The profiling service will email your profile to you (a file about 1 MB in size).

To Load any Printer Profile to your computer:

Note: After loading the profile, restart Photoshop (if it was open) so it will recognize the profile.

  • For Mac: Go to “Primary Hard Drive” → “Library” → “ColorSync” → “Profiles” and put your profile in this folder.
  • For Windows: Download the profile to your desktop, right-click on the profile icon and click “Install Profile”. You can now delete the profile on the desktop. For your information, the path for the profile location is C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\COLOR
