About Isis Locus
The turnkey software for duotone creation. Isis Locus makes duotone creation unbelievably simple, accurate and flexible. Developed by the leading authority on duotone technology, Isis Locus accurately creates and displays duotones of any color. Simple controls allow you to obtain perfect duotone images every time.

Duotone creation is just one of three Isis Locus functions. Creation of a fifth color for five-color reproduction, and a unique overlay color-correction method similar to a camera’s photo filter are also included. Duotone reproduction is for two- and four-color offset presses, highlight laser printers, and inkjet printers. Fifth color reproduction is for five-color offset presses. If you have mixed paints you will find overlay color-correction very intuitive.
