I am also in your position of trying to decide which RIP to purchase.
So far, I am sold on ImagePrint, simply for the Phatte Black option.
I'm really looking forward to what other individuals have to say.
I have had two replies.
One from Chromalink digital color tune-ups (run by a color management consultant).
" Hi Ed,
In my experience ColorByte will do better job on BW.
Hope this helps.
And one from Alien Briot who also liked ImagePrint but has not used Colorburst.
I use ImagePrint. I have no experience with colorburst. While there may be a saving,
ImagePrint is so good that this takes precedence in my view.
I have a review of it on the web if you haven't read it yet:
Beaux Arts Photography"
I have printed a black and white. Have been told by two photographers (one of whom took the photo) that they liked the Colorbust better over all. The Imageprint did a better job on the details in the dark areas but they thought the shading over all was better in the Colorburst. I should say that I have not mastered all of the settings in either application.
Also, Colorburst comes with the ability to print from apps. ImagePrint requires that you purchase another key in order to be able to print from apps such as Photoshop. It almost seems that ImagePrint is out to fleece the customer.
