Thanks to All for all the good advice gotten so far! Maybe it's time for a little checkup to see if I have been a good
student. Please would you mind correcting me if I am wrong, or if there are better ways to do it? Thanks! Here's how it
goes:
No need to say, we start with a calibrated monitor. My Mac setting is gamma 2.0 and 6'500K
a) First step: Set the Eversmart with input profile: ICC scan calibration profile and output profile: Ektachrome
J.Holmes.
b) Make the preview and edit the image for endpoints, density, contrast, cast correction. Scan.
c) Open the scan in Photoshop, and choose "prefer image profile" (if the work space is set to Adobe RGB or else). If the
image needs fine tuning for saturation and lightness, try *assign* (and not convert to) different versions of Ektachrome
J.Holmes and see how the image is improved. Or maybe I should have done it in the scanner preview window?
d) Add curves layer and make all the final adjustments, save image.
Then:
1) For Lambda output:
Flatten, resize, sharpen, convert into custom Lambda profile (By the way, what is the Durst profile found in my
ColorSync folder supposed to be for?) Make sure the BPC check box is unchecked and use perceptual (Which engine? does it
matter? Only Heidelberg produces a visible difference from the 3 others). Save, send and wait for the perfect prints!
2) Or for making small images for the web:
Flatten, resize (I use bilinear for that), sharpen, convert to web profile (normally sRGB, but I use my monitor profile
for a better match), save using *save for the web*.
By the way, when does one need to check BPC and use other than perceptual?
3) Or for CMYK printing (I know better results are from a direct scan into that mode, but occasionally a small image
already available in RGB can save time) :
Flatten, convert to CMYK profile (using perceptual and no BPC?), add new curves layer and fine tune, flatten to send. Or
in the first place, don't flatten and trash curves layer, convert to CMYK workspace, add curves layer, fine tune,
flatten and send. Receive the printed material and pull your hairs up for the printer messed it all up. No, of course
you gave him a match print and the job is perfect.
4) Finally, for desktop printing:
Choose "no printer calibration" and perceptual in the (Epson) printer driver window, input is showing the image profile
and select the paper type and with the choice of paper, the custom calibration profile made with the Spectrocam for the
output.
Admire the perfect match
There are a few issues I am unsure of, for example if the BPC check box needs always be off and if *perceptual* is
always to be used, for RGB and CMYK, when converting to profiles.
Now please don't tell me I got it all wrong, or I might give up!
I would like however your advice and tips! Thanks!
