If the image reads more than 260, there are a couple of ways to bring the image within the 240 to 260 range. If the image reads less than 260, which is usually not the case, then we are through our first hurdle. Our original image reads a total of 292: 75 cyan, 69 magenta, 65 yellow, and 85 black For black and white images, the minimum dots will go from 3 to 90% For example, if the CMYK values for the darkest area of an image read Cyan 70, Magenta 60, Yellow 60, and Black 70, then the total ink density would be 260. The 240 or 260 values represent the total ink density when you add up all the CMYK values for a given area. For newsprint, the maximum total ink densities for a color image in the darkest areas of your image should read around the 240 to 260 area, depending on the newspaper. With the Eyedropper tool, look at the image in several areas and read the densities, as shown in figure. Set up your Info palette to supply the necessary information Say OK to the selections, and the Info palette will now display your new selected options. On the Second Color readout, set the Mode to Total Ink, which will display the total ink densities on the right side of the Info palette display.
Under First Color Readout, use the drop-down menu option and select Actual Color, which will display your actual color read-out on the left side of your Info dialog box. You will be presented with the Info Palette Options box.
Click on the little palette arrow on the top right of the palette dialog box and select Palette Options. Open the Information palette preferences, bringing up the dialog box shown in figure, and set the right side of the information box to display your total ink densities and the left side of the dialog box to display the Actual Color. (If you have an RGB image, I'll discuss the transformation to CMYK shortly.) Start off by making sure the Information palette is open. Having a color image spec'd for newsprint also makes the conversion to grayscale a little easier. I say this because there have been occasions when the client has asked to spec a supplied color image that will be changed to a grayscale image, only to come back at a later date to say that they now require a color newsprint image! It just makes your life a little easier if you have both on hand. In either case, assuming I receive a color image to spec for newsprint, I always make sure I spec both a color image and a grayscale image for newsprint, regardless of what I was asked to do. There are two typical scenarios you'll encounter when working with a color file: a client may ask you to take an image and spec it for use in a color ad in the newspaper, or you may be asked to convert the image to a grayscale image to be used in a black and white newspaper ad.
