Trapping Conversion of PDF PostScript Documents to TIFF/IT-P1
PDF and PostScript data from an external source can rarely be sent directly to print. You need a proof, want to check the trapping or carry it out yourself and require TIFF/IT data for the gravure. You want to avoid running the PostScript data through another RIP for each output, during which errors can occur.
ORIS Works supplies you with the perfect solution.
During data import, conformity with the PostScript standard is checked, missing fonts and images are detected, and the pages with errors are e.g. written into a separate directory and recorded in a set of statistics.
You can display the pages on the monitor and check all of the details, e.g. trapping, and make corrections interactively. ORIS PDF Tuner also carries out automatic trapping of the entire page in addition to allowing interactive intervention. ORIS Works automatically converts PDF/PostScript documents to TIFF/IT-P1.
CT and linework can be checked on the screen and edited. For the creation of proofs, ORIS Works calculates a color-corrected TIFF/All in CT from the CT and linework file which can be output on a variety of printers, e.g. of the EPSON printer family, using ORIS Color Tuner.
Workflow
The use of ORIS Works automates the prepress workflow. A configurable Hotfolder take charge of routine jobs. The ORIS Works Hotfolder Manager applies user-defined functions to individual documents or directories. The function is described by an application program and a configuration file. Each processing step is written to a log file. A Hotfolder can be linked in a chain to automate multistage workflows. Branches within a workflow can also be created.
- The screen representation of a Hotfolder is similar to that of the Windows NT Explorer
- Color symbols clearly and constantly indicate the current document status
- Repeat feature in case of errors
- Save, ignore or delete problem files
- Error handling for files which do not match the input criteria, i.e. document type or naming conventions
- The priority of waiting documents can be changed at any time
- Documents to be edited can be pulled into the Hotfolder window using ``drag and drop``
- A variety of PC applications can be used in conjunction with ORIS Works. The format specifications for configuration files are part of the product package
- The product includes a variety of predefined configuration files which can be tailored to the user's specific applications. A separate license is required for each of the ORIS features
- Access to all data in the network
- Processing of shortcuts
- Processing of directory trees
- Transfer of files based on document name and type
- Hotfolder priority can be changed at any time
Computer to Plate Film
With the ORIS Works CTP software components it is possible to set up an efficient computer to plate/film workflow. ORIS Works CTP performs the following tasks:
Import of Documents in All Common Formats
- PDF
- PostScript
- DCS
- EPS
- TIFF, TIFF/IT
- Scitex HandShake
- ORIS
ORIS Works CTP full support of the CopyDot format allows the integration of re-digitized advertisement films into the workflow.
Pre-Flight Check of PDF Documents: During this process, ORIS Works CTP checks if all fonts and high-res. images are available and if they comply with the PostScript standard.
Last Minute Corrections: All imported documents can be edited so that corrections are still possible immediately before setting.
Trapping
Trapping: Automatic trapping can be applied to all pages, making them ready for production.
Output of Reliable Flat PostScript Format
With Flat PostScript, the complex PostScript structures are reduced to two elements: CT, which contains all image information, and LW, which contains all high-res. elements such as text, etc. This format can be processed by all equipment capable of PostScript.
Sheet Assembly
Retail programs such as Preps by ScenicSoft are used for sheet assembly. ORIS Works CTP reduces all pages to low-res. EPS files so that the assembly program is not charged with large amounts of data. A soft proof is done by reading or plotting the sheet with ORIS Works CTP software. After the signature has been accepted, the low-res. EPS files are replaced by high-res. data during an OPI process.
Imagesetters
In this area, CGS works closely with the Screen company. ORIS Works CTP is the ideal complement to the NT version of the Harlequin RIP, i.e. the entire production phase is realized using a uniform operating system and a uniform computer platform.
Trapping of Page Elements
All pages created with ORIS PDF Tuner or produced through the interpretation of PDF/PostScript documents can be trapped.
- Automatic trapping of the entire page during the export of final pages to Flat PostScript, TIFF/IT-P1 and Scitex CT/LW formats
- Trapping on pixel basis to the background and between linework colors
- Manual corrections are also possible
- The trapping can be visualized by reading the linework data
- The trap colors can be changed with the linework editor
- Finetuning of the parameters for automatic trapping
