3 Trueflow Workflow

3.1 Core Technology and Structure

Trueflow workflows use a web browser as an interface, compatible with PC and Mac platforms, and can be fully digitalized from the original dot scanning, prepress processing, color management, digital proofing to direct platemaking integration. Internet, Intranet networking, remote control. Use the Adobe PS 3 interpreter to efficiently process PDF file formats. Work pre-press work such as automatic pre-check, OPI, trapping, imposition, and proofing output is controlled by job ticketing to greatly increase production efficiency. Its main functions are: RIP data processing with PDF as its core can directly explain PDF and PS 3, and in-RIP function supports CTF and CTP data flow processing. Work ticket, layout layout and hot folder settings enable the data flow to achieve multi-functional, automated processing. The Trueflow workflow has two configurations to choose from: Huizhi and Huizhibao. By adding some software options, Huizhi can be upgraded to Huizhibao to adapt the system to the needs of specific tasks. Users can choose the most reasonable configuration based on CTF or CTP devices.

3.2 Functions and Features

In the Trueflow workflow, you can effectively manage multiple tasks by setting up job tickets and hot folders. You can use the worksheets to make documents fly, trap, and make impositions. Then, group these job tickets to create a single task, or set up a hot folder to automatically assign tasks. This automated process saves time, reduces work, avoids errors, and increases consistency. As long as PDF and PS3 files are assigned to hot folders, preflight work will be performed automatically.

Trueflow Workflow supports a variety of file formats, can receive and output the major industry standard file formats such as PDF, PS 3, TIFF (1bit, Grayscale, RGB, CMYK) and EPS, and can also receive RIPed PS, RIPed PDF, RIPed EPS , PJTF and Copydot files.

The screen uses a proprietary trapping technology that provides greater trapping capabilities through center-enlargement, thickback, and drop density trapping options. The TrapEditor (optional) provides detailed control of the trapping settings, allowing independent width and color setting processing.

The Trueflow workflow supports the "ROOM" (Rip Once, Output Many) function. That is, files can only be processed by RIP once and can be output on multiple devices. Once RIP is completed, the same raster data can be used repeatedly, the output size, resolution, and output device can all be changed and even one page can be changed.

In addition, the Trueflow workflow provides the following plug-ins to meet different levels of users:
• ImposeEditor: The imposition editor based on the standard layout layout.
· PlateEditor: can change the plate size and accessories, increase the flexibility and efficiency of the CTP process.
· FlatWorker3.0: Split different files on the same plate, and adjust the dot gain rate and XY axis position of each color plate.

4 Prinergy Workflow

4.1 Core Technology and Structure

Prinergy is the world's first complete PDF workflow management system. Based on Adobe Extreme, PDF and Job Ticket Formats (JDF), the workflow can be automatically and quickly pre-checked through a workflow processing plan and work ticket processor. , PDF standardization processing, color management, trapping, true color proofing, imposition, layout proofing, film/plate output and file management tasks.
4.2 Main functions and features

Prinergy can not only do page or layout soft proofing of analog printing effect, but also can directly transfer the transferred file to the color space of the output device or printing machine. If needed, Prinergy can also automatically convert spot colors from the source file to four colors.

Prinergy's standardized processors convert prepress data into outputable PDF files and perform a series of page pre-checks to monitor source files. PDF and PS files can be accepted directly by the workflow. CT/LW or TIFF/IT files can be imported via CEPSlink. The normalizer in Prinergy optimizes the input file into a page-independent PDF file to check for the presence of high-resolution images and fonts. If OPI or embedded fonts are not supported, error messages are sent to the operator.

Automatic trapping is based on the prestigious DaVinci algorithm. It contains a job ticket and traps immediately when the file is converted to a single PDF page. Moreover, the operator can also perform an interactive trapping process on each page individually or adjust the pages that have been trapped automatically by the trap editor. The trapping effect can be previewed directly on the screen. After these processes are completed, page-independent PDF files containing images, fonts, and traps can be generated and an intuitive thumbnail preview generated. VPS can be used to generate screen virtual proofing effects, and then output PDF pages to various color printers for color proofing through color management.

Once the file is processed, Prinergy can target PDF files for page proofing and imposition processing. Once the PDF imposition mode is specified, screen soft proofing, layout proofing, or output to the film or plate imagesetter can be generated. .

5 Gypsophila Workflow

5.1 Cardiac Technology and Structure

Gypsophila is a modular, highly flexible, practical PDF digital workflow for all its output devices from Heidelberg. As an important part of the RIP operating system, the Startech process software provides a variety of screening methods, such as irrational screening system, high-quality screening system, FM screening system and line screening technology, which can increase the details of the printed products. Levels to avoid the production of traditional print plum blossoms. The Linearization Manager module is integrated in the Starry Flow process, allowing users to set linearization data and printed dot gain data based on printed materials and press features.

The Starstrand process is also equipped with Heidelberg's new color correction management system. Its main purpose is to linearize the printing plate and adjust the CTP parameters according to the characteristics of the printing press to achieve the best image reproduction effect.

5.2 To function and features

The Gypsophila workflow can both interpret PDF files and PS files. It has rich features such as PDF file preflight, trapping, digital proofing, color management in RIP, and OPI. It can also be used with SignaStation imposition software from Heidelberg. Combine multiple layout files.

The biggest feature of the Star Process Software is its powerful RIP functionality. Its color management in RIP uses Heidelberg CMM technology to complete color conversion based on ICC files. Since these conversions are based on the final printed material and the characteristics of the press, it is very effective for supporting color management in digital proofing. In addition, the RIP internal color separation function of the Gypsophila process can output composite color files. It can also set trapping settings and preview the final results. Trap parameters can be stored and corrected by job tickets. (Wen/Ji Yongqin)
