Instruments
To measure your display or a print, ChromaSpot needs two things from ChromaChecker: the Bridge extension in Chrome, and the Bridge helper on your computer, which reaches the instrument over USB. Neither needs administrator rights.
1. The extension
From the Chrome Web Store, in Google Chrome. It relays the page's requests to the helper and has no access to the page itself.
Add to Chrome2. The helper
One installer for every instrument, for your user only. Since 0.8.1 an update works without restarting the browser.

Then measure on Ink Drawdown or Match Sample.
3. Try it
A bare reading, for checking an installation. Calibrate first with the instrument on its white tile and nothing mounted — "Calibrate all" does the three types in that one placement. For an ambient reading, lift the instrument off the tile and attach the diffuser afterwards; on an i1Studio the wheel goes to the ambient position instead, and a MYIRO-1 calibrates under its cap and then takes the diffuser. "Head / knob" says where the instrument is now. Once the instrument is connected and calibrated, its own button measures too, whenever it is pressed — the type chosen here.
Removing it
Two pieces went in, so two come out, and neither needs administrator rights.
| What | How |
|---|---|
| The extension | Chrome's extensions page (chrome://extensions) — Remove. |
| The helper, macOS | In Finder press Cmd+Shift+G, paste
~/Library/Application Support/ChromaChecker/InstrumentsBridge and run
Uninstall ChromaChecker Bridge.command. It takes the helper, the browser
registrations and the folder with it. That folder is hidden by default, which is why the
path is here rather than "look in your Library". |
| The helper, Windows | Settings → Apps → ChromaChecker Instruments Bridge → Uninstall. |
Nothing is left behind on purpose: no background service, no login item, no settings elsewhere. Your instrument's own drivers, if you installed any, are not touched.
Readings never leave your browser: the page asks the extension, the extension asks its helper, the helper asks the instrument, and the numbers come back the same way. No account, no upload.
