First, I want to thank Richard for a great book and tools. I'm a relative newbie to digital photography but I'm learning a lot.
Over the weekend, I was calibrating my printer (Canon S820) to match the output on my monitor. I've calibrated the monitor (actually, an LCD panel) with Adobe Gamma and everything looks good. Images downloaded from my camera look pretty good for color balance and brightness.
I then printed a number of test pages to try to closely match the output from the printer to the LCD monitor.
I used this for a test image: a3gencolorhigh.pdf Actually, I used the first page. It has several CMYK color patches, several grayscale bars, and some rich color images. After several pages and changing settings, I was able to nail the colors and black levels. I can hold the print to the LCD and it's almost spot on.
So what's my question? In a minute...
So all was well with printing from Acrobat, but I wanted to make sure Photoshop Elements would also match, so I opened the a3gencolorhigh.pdf in Elements and printed it again. In PE, the imaged looke the same as in Acrobat (I had both programs open, and put the windows side-by-side), and the print output matched the LCD. Again, all is well.
(As the late great Archie Bunker was known to say, "Get to the pernt, Edith!")
What I noticed was that the CMY color samples don't match a CMY color created in PSE. For example, Cyan is created in PSE by Green and Blue, and no Red (RGB= 0/255/255). However, the color picker for the a3gencolorhigh.pdf file says that the cyan is 0/172/239. And the CMYK.pdf on the HP disk exactly matches the pdf I downloaded. But the cmyk.psd on the CD has Cyan as 0/255/255, the way I could create cyan.
So maybe this is just academic, since my monitor matches the print output, but what if I were to have some of my photos professionally printed? Since the colors in the pdf's don't match PSE, will I get drastic changes in color? Or is this just the way PSE imports an PDF file? I wouldn't think so, since in the side-by-side window comparison (PSE to Acrobat) showed the colors to be exactly the same, and there were no color shifts in the image part of the a3gencolorhigh.pdf.
By the way, I have color management set to "No color management".
I think that I'm missing something here, but I'm not sure what, and I don't know if it matters.
I would appreciate it if someone could explain to me what I'm observing and if it matters.
If you made it this far in the message, thanks for reading...
