I tried doing the whole procedure again today. 

1. Calibrate monitor with a difference of only 0.20
2. Printed target prints (high quality 225colors) - I resampled the
image to 8"x10", 300 dpi on photoshop (nearest neighbor interpolation)
without assigning a profile.
3. Used FUJI FRONTIER INTERFACE to print the target print.
4. Used spectro and created a profile from the target print.
5. Opened 3 photo images and assigned all 3 images with the created
profile
6. Printed all 3 photos via frontier interface

When I compared the 3 images on the images on screen, the on screen
images still was as reddish as before.

QUESTIONS:

1. Why is this so?  I doubt I have done anything wrong here, which
makes me wonder why both image on monitor and print doesn't match at all.

2. This is so true even when i was reading the color patches with the
spectro.  I noticed that the color read by the spectro doesn't look
the way it should be on the monitor compared to the print.  Is this
just natural?

3. Is there something wrong with how the spectro is reading the colors
which is causing this problem?

4. If my procedure is correct, how can I compensate for the
reddishness of the images on screen?  There is nothing wrong with the
monitor but the image itself when assigned with the created profile
turns reddish compared to print.  

5. Is compensation done when building the profile - adjustment of CMY,
Brightness Contrast Saturation in the Build Profile Setup Window?  Or
is compensation done on the FRONTIER machine?  which is the proper way?

thanks guys!

regards,
david
