Little Argyll GUI vs QUBYX PerfectLum

Little Argyll GUI is an open-source graphical front end for the ArgyllCMS color-management system. Its controls help create and use ArgyllCMS commands for display and printer calibration and profiling, as well as camera and scanner profiling. Saved parameter sets support repeated work. The program can create daylight-series spectrum files with selectable ultraviolet filtering and custom patch sets for grays, near-grays, or tones such as sepia; printer patch sets can include those additions. Documentation links appear throughout the interface. Version 1.0.1 is a Python 3 script with a GTK 3 interface built using PyGObject, and updates Argyll 3.0.0; some parameters are absent in older Argyll versions. Linux, macOS, and Windows instructions are provided. Windows setup uses MSYS2, while macOS setup uses Homebrew. On the maker’s Windows 10 MinGW-w64 system, the background selector does not work. Use requires a color measurement device, such as an i1 Pro 3 or ColorChecker Studio. The listed price is $5 as a one-time purchase payment.

QUBYX PerfectLum calibrates, verifies and runs quality assurance for medical displays, including DICOM GSDF calibration. It automates acceptance, constancy and routine QA tests with configurable pass/fail thresholds, scheduled daily, weekly, monthly or at custom intervals. Tests produce structured PDF reports with calibration and compliance results, luminance, contrast, ambient data and history. PerfectLum supports LUT calibration, ICC profile export and multi-monitor calibration for up to six displays. It works with QUBYX SmartSensor S1 and S2 and supported third-party measurement devices, and can connect to QUBYX RemoteQA for fleet monitoring, scheduled QA, failure tracking and centralized compliance reporting. Its workflows align with DICOM Part 14 GSDF, AAPM TG-18/TG-270, ACR, DIN 6868-157 and IEC 62563. QUBYX lists installers for Windows 10/11 x64 and macOS 12 or later on Intel and Apple processors. A free trial is available by email download link, with no duration stated. A workstation license costs $480 as a one-time purchase; a package with SmartSensor S2 costs $680, paid once.
