Posted on Sun Nov 9, 2003 12:49 AM background info first...
- i'm using a GTI PDV-3/dimmer to view my prints. i have 2 sets of lamps...a 5000K set and a 6500K set.
- my printer is a fuji pictrography PG4500. profiled using Monaco's Profiler and eye-one spectrophotometer.
- monitor is a mitsubishi diamond pro 2070sb (22"). previously profiled using eye-one spectrophotometer and match 2.0.3, to 6500K, 1.8 gamma.

i was reading about Don Hutcheson's method of manually setting the monitor's white point to match the viewing device's (in this case my GTI PDV) white point instead of selecting a standard D65 or D50 whitepoint. this was how i went about doing it...
- i printed an image using my printer profile.
- placed the print in the PDV (using 6500K lamps..i was advised to stick to the 6500K lamps since i have them)
- viewed the print and viewed the soft-proof of the image on the monitor...found that it didn't match too closely (the print was a little too magenta/red)...proceeded to adjust the monitors RGB sliders to get a match between print and soft-proof.
- tried my best to make the match, but realized that the degree of match differed from image to image...anyway, settled at a setting that worked for the majority of my images.

prior to making this monitor adjustment based on Don Hutcheson's method, i had calibrated my monitor (several times to make sure i got it right) using eye-one's spectrophometer to a standard white point of 6500K. my RGB sliders were R-100% G-94.1% B-79.2%.

after making the adjustments to manually set the white point, the RGB settings become R-98.7%, G-87.6%, B-78.5%.

the big difference in the Green setting unsettled me...in fact, it is still unsettling me. is something wrong with my monitor, or the profile made by the eye-one?

now comes the strange bit...so i decided to switch my PDV lamps to the 5000K set..the settings on my monitor are the settings after i did the manual white point adjustment mentioned above. i placed my print in the PDV, and opened the image in photoshop...and somehow, the print matched the image surprisingly well...not the soft-proof of the image with the printer profile, but the image in its adobe RGB (1998) space. does this make sense?



i know this is quite a bit of info to digest, but these are my main questions:

- given what happened, does it mean i won't really need to use soft-proofing?

- is this a flawed workflow?

- should i be concerned about the working state of my monitor, or the monitor profile?

- what are your thoughts on Don Hutcheson's method of setting white points manually? am i understanding it right and doing it right? refer to

many thanks, as usual.
