## DESCRIPTION

Synthetic device model test chart reader - Version 1.6.3

## SYNOPSIS

**synthread** \[-v\] \[-s\] \[separation.icm\] profile.\[icc\|mpp\|ti3\] outfile

- **-v**

  Verbose mode

- **-p**

  Use separation profile

- **-l**

  Construct and output in Lab rather than XYZ

- **-i** p1,p2,p3,

  Set input channel curve powers (default 1.0)

- **-k** x1:y1,x2:y2,x3:y2

  Set input channel inflection points (default 0.5,0.5)

- **-o** p1,p2,p3,

  Set output channel curve powers (default 1.0)

- **-r** level

  Add average random deviation of \<level\>% to input device values (after sep.)

- **-R** level

  Add average random deviation of \<level\>% to output PCS values

- **-u**

  Make random deviations have uniform distributions rather than normal

- **-b** L,a,b

  Scale black point to target Lab value

- \[separation.icm\]

  Device link separation profile

-

  profile.\[icc\|mpp\|ti3\] ICC, MPP profile or TI3 to use outfile           Base name for input\[ti1\]/output\[ti3\] file
