    Default Nexus PDF RIP Speed Issues

    We have recently added the PDF RIP option. Although it is working correctly we have noticed that it can be really slow on some jobs compared to using PostScript and Link Files. Does anyone have any tips that could help speed things up.

    PDF workflow:
    Linework ArtPro file exported to PDF
    Imposed and PDF generated of complete imposition (138 up)
    This took 55 minutes to RIP!

    PostScript Workflow
    Linework ArtPro file, create PostScript and make Link File
    Impose and postscript imposition.
    Entire job RIP'd in under 11 minutes.


    Am going to look at trying different options in the PDF and different compression types to see if that makes any change but thought I would ask on here first. Any ideas are appreciated as at busy times this is going to get very frustrating. Don't want to have to use PDF RIP for some jobs and Postscript for others. Would like to fully move over to PDF now we've paid for the upgrade.

    I haven't made the move to a PDF workflow yet for this very reason. In a pure PDF workflow, the PDF has to be processed again at every step. With the PS/Link workflow, once the PS is processed the work is done.

    I'm sure there are details I don't know about, but I take comfort that my EskoArtworks sales rep agrees that pure PDF is still not quite there yet, at least for our hyper quick turnarounds.

    I know it's slower but I haven't seen that much of a slowdown. How much memory do you have in your Nexus box? How many instances of TotalRIP are you running on that box? We have 4 GB of RAM on our Windows 2003 server Nexus box. We have 4 instances of the assembler running on our PS workflow so I think if we were to change over to the PDF workflow I'd kill 3 of them and run at least 2 and maybe 4 instances of the TotalRIP (if possible, haven't checked yet). Also, I was told by Long to use packbits compression. One other thing I've found is it's MUCH slower if you outline the text and then have it trapped. Once it gets to the multi-up impo it takes forever to process. It speeds it up considerably if I leave the type live all the way through the process.

    We're still just in the testing stage at this time though we're going to have to go to it soon. I understand EskoArtworks it putting no more development in the postscript Nexus RIP side of things. All development/research is being done on the PDF side.

    Thanks for replies.

    Joe, we are running the same setup as you. WIndows 2003 with 4Gb RAM. We currently have 4 assemblers (2 for screened TIF's, 1 for LinkFiles and 1 for Epson Proofs). RAM was split between each assembler, obviously much more assigned to the Screen TIF assemblers, you do not have the option to adjust memory usage for the Total RIP Module.

    Most files do tend to rip fairly quickly, it seems to be jobs with either extremely large files or small files stepped up over 100 times that cause huge slow down. All our files are in ArtPro and have already had text converted to outlines, trapping has already been carried out in the ArtPro file so the PDF is just being rasterised.

    We are currently already using Packbit compression.

    Thanks for your responses.

    I'm wondering what benefit you are getting from the PDF RIP if all of the processing is carried out in Artpro and you are just using the Total RIP for screening rasterized data. It seems all you have done is slow the process with no obvious benefit unless I'm missing something here. I think the main benefits of the Total RIP is the upfront processes such as Pitstop preflight, color remapping, and trapping...all while retaining live transparency right up to the point of screening.

    Some jobs do not import into ArtPro very well due to having loads of transparencies used. So now we can at least keep these in Illustrator format and go straight to PDF.

    But yes, most jobs will be in ArtPro format and already be trapped. Most jobs will still have transparencies in them which we felt would go through a PDF better than using postscript as pDF seems to be the way to go. Not really convinced at the moment though.

    As Joe says, it is a known issue that the PDF nexus rip is really slow compared to the PS rip. I was told this would be better in nexus 9.

    I've also noticed that jobs (mostly) illustrator with a lot of tansparencies (and other Appearence settings) tend to give us problems in Artpro.

    Anyhow, if you are using nexus, i'd stick with PS for the time being...

    My suggestion would be to upgrade your Nexus box. We are running Nexus 8.6 on a dual quad core Windows Server 2003 enterprise edition with 12 gb of RAM 10,000 rpm drives. The speed of the PDF rip is incredible. It's at least 4 times faster than our PS rip. The issue that we do come across is that it does not handle transparencies very well. When it comes across PDF files with transparencies it takes up a lot of RAM. It would be interesting to look at your problem file and see if I could troubleshoot it.

    I thought transparencies were the reason to upgrade to the PDF RIP? Are you saying its still best to flatten PDF's before sending through?

    The Nexus software is not 64 bit though is it? I realize it will allow the OS to see the ram over 4 gb but doesn't the Nexus software have to run under some type of 32 bit emulation with this setup?

    And I don't get what the point of the PDF RIP is if it bogs down with transparency. That is what it was built to handle.
