Try to get an ICC profile from your local newspaper that you can load into Photoshop to check you images and to simulate press conditions. Figure 1 shows you the process through which to use the profiles in Photoshop. Prior to using the profiles in Photoshop, though, you'll have to copy the supplied profile into the following folder: On you main hard disk, go to Library -> Application Support -> Adobe -> Color -> Profiles -> Recommended.
To load the profile to view your file, go to View -> Proof Set-Up -> Custom. The Customize Proof Condition dialog box will come up, as shown in Figure 2.
Under Device to Simulate, you will want to load the newspaper profile the newspaper company supplied you with. Figure 3 shows the options that come up on my computer.
When the image you are to correct for newspaper is open and you wish to get an idea of how it may look in the newspaper, simply select View Proof Colors or Command+Y. You can now toggle between your original image as it was and what it is suppose to look like as the newspaper will print it!
Creating a compensation curve in Photoshop, as shown in Figure 4, may also be useful. You can then use the compensation curve you create to check your images as you plot along with the changes you make. You would never apply the curve, it would simply be used as a guide to show how the image may look when printed.
To create the newspaper compensation curve based on what the newspaper specs suggest, open your image. Go to your Photoshop menu and select: Image Adjustments Curves. You will be presented with the Curves palette. With the CMYK Channel mode selected, the default, click anywhere on the curve line and a dot will appear. Look at the bottom of the dialog box to your left, and you will see that numbers appear in the Input and Output boxes. The input number is the actual place on your curve line where you placed the dot. The output number represents a change made to that number.
Look at the numbers supplied to you to see how the ink gains from the newspaper. Place a dot on the curve line that represents each of the numbers. Then type in a gain value in the Output box for each dot you place on the curve line.
For instance, if you place a dot on the curve line that reads 20, and the newspaper says that a 20 gains to 30, then type 20 in the Input box and 30 in the Output box. Keep adding dots and type in the both the input and output values for each dot until you build a curve like the one in the example.
The techniques described in this tutorial will apply to both black and white and full color images.
