ChromIQ v4.3.8

For everyone updating from 4.3.7: print settings belong to each run, Windows gets ChromIQ's own print route, the instrument's button can retry a failed strip, and a good strip reading is never lost when a swipe is recognised as another strip. The details of each change are in the three beta entries below.

Added

• Press the instrument's button to retry a failed strip (i1Pro, i1Pro 2, i1Pro 3, i1Pro 3 Plus, ColorMunki). In the Strip Read Failed window the first press works like Retry, the second press starts the scan as usual. Tested on a real ColorMunki.
• Windows: ChromIQ's own print route (#205), as on macOS: Preferences > "Use default Windows printer dialog" switched off sends a PostScript printer ChromIQ's own PostScript, so RGB, CMY, CMYK and multi-ink charts reach the printer unchanged.
• Check & Refine, gamut comparison: profile A gets its own opacity and colour sliders, so a smaller gamut inside a larger one becomes visible.
• A warning before a profile or a calibration is built from a measurement with unread strips. It names the missing strips and how many patches they hold. "Go back and measure" is the default; "Build anyway" builds as before. (New texts, shown and waiting for approval.)

Changed

• Every run keeps its own printer and print options (#182), and a verification chart goes to a PostScript printer the same way as its profiling chart.
• The Strip Read Failed window explains each kind of failure on its own, including "Reading is too short" (the instrument stopped reading almost at once, for example a press without a swipe). Before, every failure was told to scan more slowly.
• "Name the installed copy after the description" is on by default for everyone who never changed it.
• macOS: the log records where alert sounds play when a measurement starts. The instrument's "ready" beep is the system alert sound. If System Settings > Sound > "Play sound effects through" points at the built-in speakers while you listen on headphones, you will not hear it.

Fixed

• "I read strip B" no longer throws away the good reading of the strip the swipe was filed under (Knut). A swipe of strip U made while ChromIQ expected strip V overwrote V's earlier, good reading; after "I read strip U" V was left unread, and a profile could be built from fewer patches without a word. V now gets its earlier reading back.
• Windows: a measurement could fail to save after a strip when another program held the file for a moment. The save now replaces the file in one step and retries; if it still fails, the readings are kept in a safety copy that the next load uses, and the line under the chart says so.
• A verification or Windows print dialog chart printed at the wrong size, the paper chosen for a chart could be smaller than the chart, and charts with extra inks printed an ink in the wrong channel through ChromIQ's own PostScript.
• The scan arrow under the last row was hidden behind the "expected / measured" label (Knut).
• An .icm profile was installed as .icc, and X.icc beside X.icm made two profiles of the same name.
• Did you know? On a Mac you can use the Mac's own Open and Save windows: Preferences > Behaviour > "Use the operating system's file browser" (off by default; checked on macOS 27, also in full screen). The manual's FAQ Q.06 now describes it correctly.
