Dealing with screened 1 bit tiffs in ArtPro to Nexus

[schenkadere]

I'm curious how anyone is dealing with this. I usually go back to the supplier and ask for a hi res pdf, but there are times they are reluctant.

We do all our stepping in ArtPro and print to various Nexus workflows.

I saw in one post that someone uses DotSpy to combine the tiffs and create a link...good idea...does this work out ok? Any other creative solutions?

Theoretically it sounds a viable option. DotSpy generates an EPS link file that can be utilised on S&R.
One must make sure, though, that the resolution of the 1-bit Tiffs is obeyed on your Nexus workflow. Otherwise the 1-bit files will be interpolated to the new resolution, causing Moiré that is hard to notice on single separations - but will definitely show up on print...

Ok...but will Nexus recognize the combined, screened tiff as a hi res? I have used links to OPPO, but never tiff.

I am not a specialist in PS program code, but to me this appears to be quite similar to the Nexus Link files you refer to.

The file DotSpy generates, is not a merged hires file (and you don't even need to 'Merge Windows' on DotSpy.) The EPS generated by DotSpy is quite like a regular Link file generated by your Nexus WorkFlow.

See this code snippet from the EPS link file I created on DotSpy from a set of Nexus 1-bit Tiffs as a test:

%PCCProxyType: Separated TIFF
%PCCLink: (Cyan) (J31P001_R_Cyan.tif)
%PCCLink: (Magenta) (J31P001_R_Magenta.tif)
%PCCLink: (Yellow) (J31P001_R_Yellow.tif)
%PCCLink: (Black) (J31P001_R_Black.tif)
%PCCLink: (PANTONE 192 C) (J31P001_R_PANTONE 192 C.tif)
%PCCLink: (PANTONE Reflex Blue C) (J31P001_R_Reflex.tif)
%SSiBoundingBox: 0 0 1842.510 1417.320
%%CropBox: 0 0 1842.510 1417.320
%%EndComments
{
/PCCReplaceImages where {pop PCCReplaceImages} {false} ifelse {
    <<
        (Cyan) (J31P001_R_Cyan.tif)
        (Magenta) (J31P001_R_Magenta.tif)
        (Yellow) (J31P001_R_Yellow.tif)
        (Black) (J31P001_R_Black.tif)
        (PANTONE 192 C) (J31P001_R_PANTONE 192 C.tif)
        (PANTONE Reflex Blue C) (J31P001_R_Reflex.tif)
    >> PCC_Separated_TIFF_Helper
}

The references to the separation 1-bit Tiff files (J31P001_R_[separation].tif) are relative paths. So the hires files must be moved to the Nexus "Pages" folder, as selected in Nexus Preferences. Nexus will then detect the image replacement function in the link file, and insert the hires Tiff data into the PostScript stream - just as it does with the OPPO files.

I tested this with DotSpy 4.5 rev 1, ArtPro 9.6.3 and Nexus 9.5.5 on Mac platform and it works just fine!
Please be aware, this doesn't seem to work with any flavor of PDF exported from ArtPro and Nexus PDF Rip. (Or I just didn't know how to do it properly... )

Yes...that makes sense. I attempted to create a link using Nexus, but obviously, it created individual links. I imagine the only way to succeed in his workflow is to have DotSpy, giving me the ability to merge the tiffs to map the colors so that the link .eps will collect that information. I guess I'll need to purchase a seat to simply to map the individual tiffs and export a link. Does that sound correct? It does to me, LOL.

I would agree. Currently it may be your best option.
While you could merge the 1-bit seps on Photoshop (depending on the compression used), it would produce huge uncompressed composite file, making working with it quite tough and slow...

I wish you success.

Yes...the Photoshop option doesn't always work because of the compression and that it is ridiculously huge, slow and cumbersome.

DotSpy it is!

Thank you for your help!

[schenkadere]

Order processed.

Works perfectly...DotSpy was the answer. Stick the individual tiffs in the Links &Pages, step the .eps link from DotSpy in ArtPro and print to the queue...voila...piece of cake. No more 1 bit tiff problems.

Glad to be of assistance!
