FEATURES

Measurement Editing and Smoothing

• New measurements graphing view that lets you select and drag outlier measurements

• New weighted moving average smoothing for better curve fitting based on the number of the original measurements

• Ink channel smoothing in the linearized .quad curves for even smoother tonal transitions

Output Density Rendering Intents

• Linear Lab L*

  • Uses a standard straight line for evenly-spaced tonal steps

• Perceptual Rendering w/ BPC

  • Adds a slight contrast curve based on the density range of the original measurements for a better screen-to-print match

• Spot Color Tone Value Correction

  • Primarily used for linearizing KCMY+ separations for multi-layer gum, carbon, or gravure

• Manual Curve Controls

  • Gives the ability change the shape of the output curve or add a saved Photoshop .acv curve file (using a grayscale or composite RGB values)

Export Options

• QuadToneRIP .quad files (with option to automatically install when saved to a Quadxxxx folder

• Defaults to a correction curve based on a negative image and “normal” .quad file, with a check-box to switch to a positive correction curve to use with photogravure or printing positive images with an “inverted” quad file.

• Adds notes for the measurement and quad files that were used to create the new linearization for easier troubleshooting and organization

• Photoshop .acv or .cube presets for correction curves and ability to use non-QTR compatible printers

• Photoshop RGB .acv curve or .cube LUTs presets for soft-proofing the measured color values or the final linearized color values with

• QTP Lab measurement .txt files for smoothed and interpolated 256-step data

• GutenPrint .xml ink channel files to be used in the “User Defined” folder

Can’t Use Your Printer with QuadToneRIP?

Even if you’re using a printer that isn’t compatible with QuadToneRIP, you can still take advantage of QuadToneProfiler-DN v3’s industry-leading data-smoothing and rendering intent tools. By exporting Photoshop .cube lookup tables (LUTs) from the QTP-DN’s system, you can apply highly refined correction curves directly to your images in Photoshop.

Why Use QTP-DN’s LUTs for Non-QTR Printers?

While you won’t get the full benefits of linearizing ink output at the printer level, using QTP-DN’s LUT-based correction method still provides superior accuracy and control compared to traditional Photoshop curve adjustments or other digital negative systems.

1. More Advanced and Accurate Correction Curves

QTP-DN v3 uses sophisticated data-smoothing algorithms and rendering intents that create far more refined and predictable tonal adjustments than manually adjusting curves in Photoshop. Instead of relying on trial and error, you can generate highly optimized LUTs that accurately correct for your printing process.

2. Customizable Rendering Intents for Different Processes

When generating your correction LUTs, you can choose from different rendering intents that prioritize smooth tonal gradations, shadow and highlight retention, or maximum contrast, depending on your specific alternative process needs.

3. Eliminates Common Pitfalls of Hand-Made Photoshop Curves

• No Posterization or Banding – Hand-drawn Photoshop curves often introduce unwanted artifacts, especially in midtones and highlights. QCDN’s automated smoothing prevents this.

• Better Highlight and Shadow Control – Instead of manually tweaking contrast and exposure adjustments, QTP-DN creates LUTs that optimize the entire tonal scale.

• More Reliable and Repeatable Adjustments – Photoshop curve adjustments can be inconsistent and subjective. QTP-DN LUTs provide a scientific, data-driven approach to correction.

4. Works with Any Printer and Any Inkjet Negative Workflow

Even if you’re using a printer that isn’t QTR-compatible, you can still use QCDN v3 to generate precision LUTs and apply them to your images in Photoshop before printing. This means you can get dramatically improved digital negatives on:

✔ Epson SureColor printers that don’t support QuadToneRIP x750 (2400dpi) models

✔ Canon and HP printers

✔ Any inkjet printer used for digital negative production

How It Works

1. Calibrate and analyze your process using QTP-DN’s profiling system.

2. Export a Photoshop .cube LUT tailored to your specific alternative process.

3. Apply the LUT in Photoshop to your image before printing.

4. Print using your standard workflow, with a more accurate and process-matched digital negative.
