TurboPrint & PrintFab

I'm trying to print an image with saturated reds, blues and greens, but the printed colors turn out greyish or muddy, especially the greens.

I'm using a HP z3100 printer. When I print the image straight from GIMP using the Adobe 1998 profile with the HP drivers, the image turns out as I expect, mostly matching what I see on my monitor.

When I print through Printfab Composer, the colors are desaturated and distorted. They don't look anything like what is displayed in the softproof view in Composer

I have used various papers, including Hahnemuhle smooth photo rag. I have used both sRGB and Adobe RGB 1998 color space settings. There are slight variations in output, but none of the Printfab outputs come close to the GIMP output.

I have tried:

Using a custom paper profile with no icc profile
Using the built-in "Plain Paper" profile
Using Hahnemuhle's icc profile for my printer downloaded from their site

Is there a way I can use Composer to send the image raw to the HP printer driver, so the printer can produce a result comparable to the GIMP output?

I'm attaching an image printed on the smooth photo rag paper using Hahnemuhle's icc profile. The print includes a patch file for shades of green, that shows how badly distorted the color outputs are. The original of the patch file can be seen at: https://www.color-meanings.com/shades-of-green-color-names-html-hex-rgb-codes/

Hello and please excuse the delay. Of course this should not be the case. If you print on matte fineart paper directly from the PrintFab Composer, the settings

- Quality = Medium or High
- Mediatype = Hahnemuehle Smooth Fineart

below should produce a print in good color quality - see below:


Your print of the green color swatches looks as if no cyan ink was used at all. How did you print the other image (with the flower)?
I recommend to make a test print with a test image that contains more colors like the one I have attached below:
