The fonts in a K color on a page on the Pages main tab may appear as 100% black if the GN4 system uses color profiles. The percentage of black depends of the color profile selected for screen and for color list. Two color profiles work together to give you an idea - as close as possible - how the page will look in printing. Therefore, the fact that the fonts are not 100% black on screen is not a bug, but a feature.
Review the color profile, selected for the screen
On the Pages main tab, on the Edit menu, click Preferences, and then click Display.
Review the name in the Video Color Profile. This color profile may be different for each user as it is a personal preference that acts concomitantly with the current computer monitor and video adapter. Therefore, the same settings may give different results on different monitors. Do not leave the color profile field empty.
Review the color profile, selected for the color list
On the Pages main tab, on the Edit menu, click Color settings, and then look at the Color Profile field.
This color profile is common to all users, but it may be different for each typography - title. Do not leave this setting empty. See Assign color profile to colors for the procedure.
To measure the percentage of black on fonts on screen
1.Open a sample page on the Pages main tab in Fred4, and zoom fonts closely as on the left part of the screenshot.
2.Do one of the following:
•Use a tool (Snipping Tool on Windows 8 or similar) to capture the Fred screen, and then press CTRL+C to save the snip to the clibpoard.
•Press the Print Screen button.
3.Run Photoshop (or any other software that is able to measure the color values).
4.In Photoshop, on the File menu, click New, and then ensure that selected preset is Clipboard.
5.In Photoshop, on the Edit menu, click Paste.
6.Display the Info palette, and then click the Eydropper tool and hower it over a letter of the image.
7.Read the R, G and B values. They may vary betwen 0 and 40 - lower is better. Values are 20 are OK for standard color profiles. To achieve the 100% of black on screen (e.g. 0 in R,G and B), use Photoshop 5 Default CMYK.icc for color list. Note: the mentioned profile may not be suitable for the press.
