Halftones can be printed with any ink color
dense enough to hold the dots in all areas of the photograph. |

Varying the formulation of black ink can
change the feeling of a halfone. Add blue ink for a cooler
feeling. Add red ink for a warmer feeling. |

Ink colors are usually best selected by
evaluating tonal values of ink samples screened to 50%
to 70%. This is because every area of a halftone consists
of a screen value. |

To most easily achieve a high contrast
halftone, use an original photograph with simple compostion.
High contrast film will automatically eliminate the lighter
grays and register darker grays as black. |
