Heidelberg has developed Prinect Production Manager not just as a workflow for prepress but as an all-encompassing solution for printers to produce their work from estimate to shipping. Almost everything you could ever need to produce work in offset, packaging, label and digital are included. The data doesn’t flow just one way, it comes back as analytics for your shop. One of the goals of this blog is to highlight all that can be achieved using this wonderful workflow. In a past blog, I discussed how we can use Production Manager to create a variety of different types of color managed proofs.

The main two components of the workflow that are used for this purpose are Color Proof Pro and Proofing Engine Manager. Color Proof Pro allows us to directly connect to many proofers and their built-in spectrophotometers. Proofing Engine Manager allows us to write a rasterized file to a specific network location – this could be a hotfolder for a device or a file-based proof for the customer. For example, in the first part of the blog “Use Prinect to the Fullest” I talked about how Prinect can connect to many different systems.

Today, let’s take a look at the specific settings of Proofing Engine Manager. Proofing Engine Manager creates a rasterized or ripped file in numerous formats.

Why is it important they are ripped? If they are being sent to another RIP, there is nothing for it to misinterpret. Everything has been rasterized to basically some form of image up to 1200 dpi. This output is then more consistent and predictable. Many of the formats can be viewed easily, e.g., a rasterized pdf. Some third-party proofers require certain file formats and compression as it’s input data. These can be configured in Proofing Engine Manager.

Proofing Engine Manager is accessible on the server where the Prinect Production Manager software is installed. Just go to the Start Menu and scroll to Heidelberg Prinect Renderer and choose Proofing Engine Manager.

I have made examples of the 4 file types Proofing Engine Manager can generate. The formats are PDF, JPEG, TIFF and Postscript. It can be used to output pages or impositions.

The first format we will look more closely is PDF. The data is rasterized with a PDF wrapper. In my experience, this is the format I use the most. It is recognizable by most other rips and can be easily viewed. The first option you can choose is whether the PDF is ripped to CMYK, regardless of the colors in the job, or whether it retains any or all spot colors. Keeping the spot colors tells whether or not the proofer is able to reproduce those spot colors.

Based on the resolution you assign in the workflow, the file can be very large. Sometimes it is a balancing act between quality and size for certain applications. Different types of compression can be applied.

Lossless compress like LZW and for possible heavier compression but the chance of lower quality lossy jpeg compression. LZW explained:

Lossless Compression:

JPEG I covered earlier in this article but here is lossy compression explained.

You can also choose whether it should create all of the pages in your original PDF or a PDF for each page. If you are outputting an imposition, it can be the entire layout in one PDF, or each side of each form is output as a separate PDF file.

In Part 2 I will cover the other 3 formats and how they are configured. Just another part of the “Swiss Army Knife” of production that is Prinect Production Manager.
