QuadToneProfiler—K3

curve creation and linearization tools
for Epson UltraChrome K3 PrintERS

These new self-contained QuadToneRIP tools allow for easy toner profile creation and linearization. The built in starter curves are compatible with all standard UltraChrome K3 printers and ink sets, including the new SureColor P600-P900 printers. 

Pre-made Curves for Common Toning Profiles

The shape of the pre-made starter curves are designed for easy linearization with the built-in tools, and allow them to be compatible with both the Stylus Pro and Sure Color printers. They do not require any manual calculation or the need to compile QTR-curves from ink descriptor files.

Now with a new feature to preview the toner color with output CIELAB values and on your image before printing.

starter Curves for interpositive and Direct to plate Photogravure

If you are using photopolymer gravure, you have the option of choosing to make an interpositive and stochastic screen two-exposure method or a direct to plate approach with a single exposure (using MK ink). Additional smoothing tools solve some of the problems with inking and wiping that some people might encounter when getting starter.

Powerful Built-in Linearization tools

Linearization is done with a standard 21, 51, 128 or 256-step target.

The behind the scenes smoothing and linearization functions shift the final quad curves to the needed levels for perfectly smooth prints.

The stand-alone linearization system allows you to reshape and preview the final quad curves without any additional need for the standard QuadToneRIP tools.

Easily export the linearized curves, Photoshop .acv curve or LUT .cube file with a single button and get on with the real printing.
