The usual reason for dark prints is due to the monitor being too bright. You adjust an image on the monitor so that affects the print indirectly.
Either adjust brightness as part of the calibration process (depends on software used or adjust brightness to match print and then calibrate to produce monitor .
But coming back to your question about brightening a set of images for printing, 2 ways.
Place images in queue, double click the first to open the image editor, brightness and OK and DONE. A dialogue will appear, put a dot in"Apply to all Images in the queue.
Or .. add some brightness as required to one image that has no other adjustments in the editor (double click thumb) then File, Save current parameter to file and use a meaning full name.
You can the set that as print filter; it's not seen on the screen and only affects prints. P Filter tick box is bottom right of the Job Properties tab.

Hi Paul,
Does the Blue Eye Pro software allow you to set a luminance value?
My EyeOne 2 software does and suggests 125 Cd/Msq for an LCD Monitor. I now use 119 Cd/Msq to ensure prints match screen for brightness. The software uses the set value to as a target when I adjust the adjust the brightness before the actual calibration takes place. I use the native value of contrast (50%) for my Eizo monitor.
