Adventures in Prepress
Once in awhile I come across a good case example. Today, there are no Corel products involved – at all – in what I want to show.
A job came in as a PDF, I printed using Adobe Reader to a PS3 device (Xerox DC-240). Notice the anomalies on the scanned press sheet relative to the "pure" look of the art in Adobe Reader. The overall hue isn't the issue as much as the discolored blocks where there are drop shadows nearby.
Someone told this budding designer to design in Pantone colors. The same had happened to me once too, for a job to be output on a CMYK device. LOL.
Anyway... during the conversion of drop shadows with spot colors these anomalies appeared on the press sheet.
So... this post shows that 100% Adobe-land has problems also, and that if you struggle with CorelDRAW and are tempted to jump the fence? You still have to mow the lawn, and there are new weeds to pull.

Hi Jeff
Sounds like it needs Adobe PDF Print Engine upgrade to RIP and unfortunately dropping into RIP as PDF not yet common place. I don't think Fiery has even provided it as a upgrade. Though Xante has for Ripit imagesetters for printing plate making.

Alternative Work Around set to Rasterize or Send as Image from Adobe at a high DPI to minimize problems with vectors - not to bad for a 1 page item but a problem for a book as each page is being converted to bitmap and sent over the network and the resulting file on the RIP may be large enough to lock it.
