create profile with more CMY and less K

[pressman.in]

Dear members, we are working with a digital printer for printing photo album application. is there a way we ca create a profile with more cmy and less K to increase the color saturation part. when this rgb images are onverted to cmyk by the rip or custom profile there is a huge loss of color. we have profile maker. If anyone has any alternative idea please suggest.

pressman, is it just bright/rich RGB colours (blues, purples, oranges) that are having problems in CMYK? Or are less saturated hues also having problems too?

Is the output device calibrated regularly to bring it back into line to similar conditions that is was profiled in? Is the output driven by a printer driver or RIP controller? Can you post a link to the output profile for this printer?

I am guessing that this is not a GCR issue and that having "less K" and "more CMY" will not help, I am also guessing that this is a regular RGB out of CMYK gamut issue. Can you post a link to some image examples of the RGB files?

hi stephen, you are right. it is the regular rgb to cmyk loss which is seen in the print. we want to convert rgb to cmyk or device profile created to specific media without loss. loss is because the digital press is cmyk based. is there a way out of it.

Hi pressman.in,

What CMYK profile are you converting to? Have they provided you a press profile? IF you could provide a sample RGB image and your CMYK file it might be helpful. Right off the bat I'd lean towards possibly a device link profile or, as a stretch, using image enhancement software to increase saturation in cmyk.

You can optimize the conversion, but it is most likely that you will have some loss of gamut.
