QuadToneProfiler—DN
for digital negatives and photogravure
FEATURES
Built-In Printer Setup and Curve Installation Utility
Printer Installation Utility to setup and simply working with the QuadToneRIP printers
Ability to automatically install and/or update quad curves without needing to run the installxxxx.command file
Starter Curve Setup
controls for extra UV blocking Density
Start with the default ink levels for common platinum/palladium systems or use the simple tools for finding and setting your needed blocking density.
The total blocking density needed can be found with one additional step using a special blocking density quad curve and calibration image. The increased overlap of the Light Black and the five color inks ensure clear highlights without excessive ink loads.
The macOS application has additional controls for fine-tuning the starter curve ink levels in the highlights, midtones, and shadows prior to linearization.
Premade Starter and Density Test Curves for Digital Negatives and Direct to Plate Gravure
The standard pre-made quad curves are designed for common platinum/palladium printing formulas.
Standard starter curve suitable for most processes
Traditional Cyanotype
Lodima/Lupex/Azo contact paper curves
Ilford Multi Grade Classic and Warmtone paper curves
Direct-to-Plate Gravure
Built-In maximum black density and DTP-Gravure open bite test curves
Advanced Linearization and Soft-proofing Tools
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
