Answer:
You can increase the color scale and the font size in the panel for the printout as follows: Set the Absolute size of the panel and, if necessary, increase the text factor in the "Color Scale" tab of the Graphic Printout dialog box (see the image). You can also adjust this setting later in the printout report under "Properties" of the graphic.
If the font is enlarged, it is usually necessary to adjust the height of the color scale as well. Otherwise, the font would overlap with the color scale.
