Hi Everybody,What's a "rich" black.My photos are posted on the web. They are also printed at COSTCO in various sizes from 4" x 6" to poster sizes. COSTCO uses a photographic printer for the smaller sizes and an ink jet printer for poster size prints.My final files are made in PhotoPaint and flattened in a TIF or JPEG format.Phil
Black at 100%K tends to be on the gray side as it's just one color. Rich black uses CMYK to create a darker black. A rich black. ie 100%K 100% CMY
I'm not sure exactly where you are going with the question. What are you trying to accomplish?

Yes and not, it's correct since it will be converted to CMYK and sRGB provide a wide gamut, enough for a good mode convert, but the change is made for other people, not you. In other words, you don't see the final CMYK image and you don't have control of the changes. If you trust on the people who works with you, it's fine, but as a general rule we can't let other people adjust our images, change colors and make color corrections.
Phil1923 said:Pure black is not totally black because the black ink uses a "transparent" ink. Would it not be better to use an opaque ink for black even though the CMY inks are transparent. Or doesn't it make any difference if the black ink is transparent or opaque.
Although it seems easy, it's not possible. The "transparent" inks allows the mix when you print 4-inks overlapping the dots. An opaque black will produce a wrong black coverage: all dark areas will be a black patch. btw as i said before, some printers use two black colors, a transparent CMYK for text and photos, and a opaque Pantone Black for a background. Of course, that increases the price, the time, etc
