"FormProof" Sequence Template
Like the "ImpositionProof" sequence, a "FormProof" sequence is also used for proofing sheet layouts but this sequence is designed especially for proofing in a "ROOM proof workflow".
If you use the TIFF-B Export functionality to control an imagesetter using, for example, a Prinect Shooter, you have the option of using the ROOM proof workflow. In this case, the proof data are calculated from the screened TIFF-B data without having to run through a separate RIP process for proofing as is the case with an "ImpositionProof" sequence. In this process, the TIFF-B data are descreened, converted to contone images and output to the proofer. This process is known as a "ROOM" proof (RIP Once Output Many). Because the ROOM proof workflow is based on TIFF-B data, the "FormProof" sequence can only be used in an output where TIFF-B files are generated, namely in TIFF-B export.
This workflow is extremely reliable in providing a correct preview of the imaged result. This is because the ROOM Proof data are calculated from the high-resolution TIFF-B data. This reliability primarily concerns the properties of the ROOM proof as an imposition proof to check the correct layout and positioning of the elements on a sheet. True-color proofing is not guaranteed in a ROOM proof workflow. One of the reasons is that the TIFF-B data can already include information, for example, from process calibration and/or linearization.
Analog to the "FormProof" sequence, imaging in a ROOM workflow is controlled through the "FormOutput" sequence. The concept of the ROOM proof workflow is such that the "FormOutput" and "FormProof" sequences must be used together in a ROOM proof job. For that reason, you must always assign both sequence types to a job.
The generated TIFF-B files are preserved in a ROOM proof workflow with "FormProof" output. The "FormProof" sequence generates hardproofs or softproofs from the TIFF-B files that were generated by a "FormOutput" sequence, depending on which "device" is set up in the "FormProof" sequence.
You can configure the following options in the "FormProof" sequence:
