Profile Prism - how does scanner profiling and monitor calibration related to each ot profiling, Prism, scanner, calibration, monitor

blueice

Hi,

I used Optical to calibrate my monitor. I bought and received Profile Prism yesterday. I ran the scanner profiling based on the steps on Profile Prism and generated a profiler.

When I profiled my scanner, I just adjust the exposure to -2 and the profile prism generate a profile. This is simple enough. However, I couldl not see what\'s the link between the monitor calibration and the scanner profiling. There seems no relationship between the two.

I\'m about to profile my printer. But really think I may have miss something. After all, the gola is to color match monitor & scanner & printer, not just scanner & printer.

Can someone point out?

Eric.

what you are doing is ok, you just need to profile your printer with the paper type you use and you will have completed the process

scanner, printer, and display profiles are \'device\' profiles, they are not related to each other

a device profile defines how to translate device colour to or from a standard colour model (the profile connnection space)

so the process for displaying a scanner image via an application set to use adobe 1998 as the working space (the colour space that you edit and store images in in) might be...


scanner colour
V
convert to pcs using scanner profile
V
pcs colour
V
convert to working space using adobe 1998 profile
V
pcs colour
V
convert to display space using display profile
V
display colour


there is no connection between the scanner profile and the display profile, they only relate to the pcs, so scanner profiling, monitor profiling, and printer profiling, are each stand-alone activities

for instance, if you change your paper or ink type you do would not need to reprofile your scanner or display, only the printer profile would need recreating

The scanner is an input device; the monitor an output device (the printer is another output device). Programs like Photoshop and Qimage translate ICC/ICM inputs to ICC/ICM outputs.

"X" w/profile (inputs) --> ICC aware program (translator) --> "Y" w/profile (outputs)

"X" can be any profiled input device; "Y" can be any profiled output device.

Inputs: scanner, camera, Adobe Photoshop, etc.
Outputs: monitor, printer, etc.
ICC aware programs: Photoshop, Qimage, etc.

With Qimage, when you preview the image, you will notice that it first displays unprofiled/untranslated, takes a second or two, then displays a profiled/translated image.

If you do a search on DPREVIEW, you can find other more detail explainations.

Eric,

I just bought OptiCal and ProfilePrism as well. I profiled my scanner an Epson 2450. I also made my first profile for Epson PGPP for my Epson 875 printer. I am amazed by the prints that came out of that printer today (using QimagePro)...they actually look like what is on the sceen.

I am in the process of making a profile for Colorlife paper..hope it works as well as it did for PGPP.

As others have said you profile the scanner for input and the monitor and printer for output. With the goal being that you can scan something in, look at it on the monitor or print it and they look the same.

Regards,

Bill

Hi all,

Thanks very much for your rply. I now know better. I went through the printer profiling. But when I used the result profil to print a photo I have (set Rdobe RGB 1988 in PS), the print out didn\'t really match up.

Here is what I did:

1. The monitor was calibrated to a perfect 90 of 6500K, gamma 2.2, with Optical.

2. Calibrate the scaner of my all-in-1 Epson CX5200:
.The Epson twain driver will not let me adjust exposure if I select "no color correction". So instead I set "Display Gamma 2.2" and adjust the exposure -2. The Prism when I did the scan, the Prsim siad it is almost perfect.
.Is this correct or I should set it yo some other way?

3. When I print the Prsim print-target-30, I also scan it with the scanner set at gamma 2.2, exposure -2 as above. with the print out, I made the final profile for the printer part of CX5200 (which is same as Epson C82 printer.

4. I then print a phot of mine with
Do you see any mis-step I may have?

Eric.

Eric,

Did you leave the printer settings the same as when you made the test print for prism?

Yes. When I do the test print, both in Photoshop and for printing print-target-30, I have turn off all Epson pinter driver color corrections.

if you mean you selected "no color adjustment" in the Epson print driver, that\'s the problem. Click on the driver settings link in the help under "Profiling a Printer - Step by Step", or alternatively, click this link:

http://www.ddisoftware.com/prism/help/driver.htm

Because the resulting prints will be too dark to scan with a flatbed scanner, you should not use "no color adjustment" in an Epson print driver to create/use your profiles.
