This is a rather large tiff file used to test the smoothness of all your digital negative/positive work. In particular, the positive and negative circle gradients have a way of making ‘ramps’ in your correction curves very obvious.
Quadtone RIP profiles for making digital negatives. Zip file contains profiles for making digital negatives on the Epson 1400, 2200, 2400, R3000, 3800, 3880, and 7800 printers.
This is a tutorial I wrote several years ago outlining the steps needed to use QuadTone RIP to create digital negatives for alternative process printing. For those who want to achieve the highest level of control over the digital negative process, the QuadTone RIP process still has no equal, albeit at the expense of a steepish learning curve. This tutorial is my attempt at creating a systematic way to use the QuadTone RIP driver for making negatives (and positives).
This is a photoshop script written by my good friend and computer maestro David Eisenlord that painlessly creates a gray-curve-linearization Photoshop curve that can then be directly loaded into the QTR ink profile that is being built. This curve takes the headache out of thinking in ‘negative space’ during the QTR calibration process. As in, oh wait, my highlights are too dark, so that means I need to add more ink, right?
This script helps to minimize some of the mental gymnastics involved. I use it in the QTR tutorial download on my site.
