Help with colour matching problem and 'colorize'
Greetings.
I'm a casual Gimp user. I have to make a brochure front-cover thing,
consisting of a collection of existing images. I'm having trouble with
colours.
One particular image ( which is mostly blue, and is a large JPEG file )
copies and pastes correctly into a new image. When I print it, however,
it turns quite cyan. I thought this might just be my printer drivers or
something ( Epson R1800 with the latest gutenprint / gimpprint drivers
), but then I noticed something very interesting.
When I select the layer with the blue image, right-click, and select:
Layer ==> Colors ==> Colorize ...
the blue image turns the *exact* colour that it turns out when printed -
cyan. I've tried playing with the 'Hue' and 'Lightness' sliders. I can
sort-of get a colour similar to the original, but not really. If I click
'Cancel', the colour returns to the original colour.
What's going on ( specifically, why does the blue layer change colours
the moment I open the 'colorize' dialog, and is this related to the
colour of the final print ), and is my colour matching problem something
I'm doing wrong / something I can fix?
Thanks :)
