The darkest patch of a strip must be read first unless there is at least 1.1
″
(27.9mm) unprinted trailer after the
last patch.
•
When possible, strips should be read so that the instrument does not ride on un-read patches. This prevents
accidental marring of un-read patches that may cause reading variations.
•
To obtain consistent measurements the same backer should be used underneath every sample. ANSI/ISO
specifies a neutral gray of at least 1.5D, which will appear black. Backers consisting of the same print stock
have also been utilized.
Strip Measurement
The following information is provided to familiarize you with reading strips, a series of printed control patches.
1. Select strip type to measure from the host software.
2. Position the instrument at the leading edge of the strip to be measured. The centering alignment marks should
be centered on the strip patches.
3. Press and hold the instrument button while rolling the QuickCal across the strip. The LED indicators will slowly
flash green during the reading. For best results, pause with the button depressed before starting a scan, and
release the button only after the scan has been completed.
4. A successfully reading is verified by a beep and solid green LEDs on the instrument, or a conformation message
on the computer monitor.
Some software packages define strips as “multi-pass” where all color passes must be read before a conformation is
displayed on the monitor. In these cases, a successful reading of a color pass is shown by the instrument slowly
flashing green after the reading. This indicates that you may continue to the next color pass. Fast flashing of green
indicates a re-read is required on the pass. The instruments LEDs will stay at solid green after all passes are
successfully read.
