Work Flow change

[Guest]

Hi,

We are at present using CMYK work flow with final PDF in version 1.3 being sent to RIPs.

As we are printing in multiple presses (of different makes) by changing to a RGB workflow, we feel we can have IN RIP CMS to convert to CMYK with seperate profiles for each press. Will this help? Is anyone following RGB workflow, if so, please share your plus and minus.

Also we are thinking of moving to PDF 1.5 workflow. This is to overcome the hanging of the PREFLIGHT software which tries to flatten transparencies in files that contain hundreds of transparency vector objects. Again, is anyone following PDF version 1.5 workflow, if so, please share your plus and minus.

Thanks in advance

Siva

Probably best to move to a PDF/X-4 based workflow if you can. Rendering transparency in-rip is a very good idea but test first.
Remember to include all the workflow components, normalisers, imposition, trapping, color management. The output can be affected at any point.

The burning questions are - is your RIP using an APPE processor or CPSI or some third party PS emulator etc.

Apart from in-RIP colour management, how does the RIP handle flattening?

Another option instead of RGB, could be to target everything to a single CMYK press condition and use CMYK to CMYK DeviceLink profiles to repurpose.
