How do I use Import Curves function?

How do I use Import Curves function?

2008-05-05 by rschoner

Hi,

I have the PrintFix Pro with the Spyder3 Print software.  I have 
generated several variations of profiles for an Epson R1800 printer 
with an InkRepublic CIS and Image Specialists using Ilford Pearl 
paper. I am now in the process of selecting and editing the "best" 
profiles to use. I would like to try the "Input Curves" option but 
don't know how to proceed. How, and from what, do I develop the acv 
correction?  I tried printing a test image with the profile, then 
scanned it in and generated an acv correction in PhotoShop but that did 
not work at all. Any suggestions would be appreciated.

Thanks,

Bob Schoner

We plan to put up a video on that topic before long. In the meantime, here are the basics:

Softproof your RGB test image (Ideally the SpyderProof Matrix test image) through your Spyder3Print output profile in Full Photoshop, by selecting it in Proof Setup > Custom.

Do not choose Black Point Compensation.

If you wish the result to match the SpyderProof SoftProof, choose ink black and paper white checkboxes.

Go to Image > Adjustments > Curves.

Be sure that Preview is checked.

Make any density adjustments you wish to the RGB composite (default) channel.

Make any color adjustements you with to the individual Red, Green, or Blue channels.

Save this Curve Set (in CS3 this is now hidden under the tiny menu box next to the preset popdown).

Apply the Curve Set to your image, and print through the profile you SoftProofed through.

See if the result is as desired.

If not, open the test image, SoftProof again, through the same profile, open the Curve Set, and adjust as desired, then resave.

Repeat until satisfied.

In Spyder3Print select the measurement set(s) that were used to create your SoftProof profile above.

Apply the edits when building a new version of your profile.

Print a SpyderProof test image to see the results; they should match the results using the Curve Set and Profile from Photoshop.

A request for the forum. For any videos that are put up on the 
ColorVision site, could there be a notice here and a link posted in 
the "Links" section of the this forum, along with a title and/or a 
short description of the video.

Isn't there some form of "Version Tracker" or the like, which will watch a web page, and send out an email whenever a new link is added to that page? I assume someone could set that up to email the group automatically, if they were clever at such things... especially if they were a group moderator...
