The TrueTypeHints system parameter controls how the RIP behaves when there are faults in a TrueType font hinting program:

`/Check`	Causes bad hinting to raise a `rangecheck` error, halting the job.
`/Safe`	Causes bad hinting to be ignored—the individual glyph or font affected will be unhinted, but other fonts will be unaffected.
`/Silent`	Is the same as `/Safe`, but does not report the problems in the console.
`/None`	Switches off all TrueType hinting (not recommended).

For example, to switch on silent handling of any TrueType hinting errors, use:

            currentglobal true setglobal
            <</TrueTypeHints /Silent>>setsystemparams setglobal

The default for this parameter has been changed to /Safe. This means that jobs containing TrueType fonts with broken hinting programs will render, instead of failing with invalidfont.

If invalidfont is required in these circumstances, /TrueTypeHints must be set to /Check. Warnings can be suppressed by setting it to /Silent.

Default: /Safe.
