When trying to flattern the images and using the same background as specified for print, I get a complete mixup (different type of red in the image than the background). For editing images I use gimp and Scribus Version 18.104.22.168 for the layout.

I ended up using icctrans to find the RGB color which produces the
nearest of my background and having my images prepared with this
 I noticed that EuroscaleCoated and ISOcoated profiles do generate
sub-optimal values when used to convert CMYK to RGB - given these RGB
values, very different CMYK values come out.
