The Contract Proof - 2000

And now—true halftoning.

One Halftone Analysis
The main argument against ink-jet proofing was always the lack of halftone dots, but this limitation is passing. As ink-jet resolutions approach those of an imagesetter, halftone-accurate ink-jet proofs up to 175 lines per inch are now feasible.

The main reason for halftone proofing is to predict moiré. At 720x1,440, the current AgfaJet Sherpa 43 can already generate 70- to 100-lpi screen-angle rosettes and, with future enhancements, the Sherpa will simulate 150- or 175-lpi screens. If the same RIP is used, the halftone dots will be the same shape, ruling and angle as those on the press sheet—not just an approximation.
