What it checks
A style the core certifies reads in practice, and reads about as well as plain black on white.
Why
Certification photographs each style in a model before it is allowed. This is the check that the model's verdict holds on real paper and real cameras, style by style.
Test codes
Print or open the sheet at https://openckey.org/tests/sheet?id=FT-07. It is drawn by the CKey web SDK from the values below.
| Code | Size | Version | Level | Layout | Style | Holds |
|---|---|---|---|---|---|---|
| A | 1.5 in | smallest that fits | M | standard | plain | https://openckey.org/t/FT07-A |
| B | 1.5 in | smallest that fits | Q | standard | concept | https://openckey.org/t/FT07-B |
| C | 1.5 in | smallest that fits | M | standard | dark | https://openckey.org/t/FT07-C |
| D | 1.5 in | smallest that fits | M | standard | accents | https://openckey.org/t/FT07-D |
| E | 1.5 in | smallest that fits | M | standard | dots | https://openckey.org/t/FT07-E |
Set up
- Print the test sheet in colour at 100% scale; each code is 1.5 inches wide.
- Use ordinary indoor light and hold the phone about 20 cm away.
Steps
- Try each code, A to E, for up to 5 seconds.
- Record whether it read and roughly how many seconds it took.
- Note anything about a style that seemed harder, such as needing to move closer.
What to record
- Read within 5 seconds, boolean, required. For each of: A plain, B concept, C dark, D accents, E dots.
- Seconds to read (s), number, optional. For each of: A plain, B concept, C dark, D accents, E dots.
Every report also records the device, operating system, reader and its version, and the printer or screen.
How to grade it
- Pass: Every style read.
- Partial: The plain code and at least three styles read.
- Fail: The plain code read but two or more styles did not.
