Digital Negatives using QTR and QuadToneProfiler-Pro-DN-April-22-23, 2023

Regular price $300.00 $0.00

taught by Clay Harmon


This two-day class is all about making the best bespoke digital negatives for any print process. We will use Epson printers in the class and a printer driver called QuadToneRIP. However, the concepts that are covered can also be applied to non-Epson printers with some modifications.

A step-by-step workflow will be demonstrated using the cyanotype printmaking process. By the end of the class, we will have covered the details of a negative-making procedure that is capable of faithfully reproducing the image seen on the computer screen onto the resulting print.

We will be using Mac based software for this class, but many of the tools or similar tools are available for Windows users. In particular, the QuadToneRIP software runs well on both systems.

The workshop fee includes all materials.

What you need to bring

A desire to understand how to consistently produce digital negatives for any photographic process using them. We will have time to print a few images from each participant, so bringing a camera phone or thumbdrive containing a few images you would like to print is a good idea.

What you will take away

1. An understanding of the basic workflow common to any digital negative creation process.
2. Specific knowledge of how to use the QuadToneRIP, PrintTool, and QuadToneProfiler-Pro-DN software
