Hi guys, me again !
My boss has designed a layout in Corel x5 and he has added a drop shadow glow to a vector logo - i am unsure how he did this, sorry, i hope you are all a lot better than me in Corel so you will understand how ?!
My problem is that when i create a pdf file and view it in acrobat, we lose the nice soft glow - we get what looks like a fat shadow - If i create a ps file (for outputting to our large format printer), my RIP tells me that a potential conflict may exist between spot colour replacement and a flattened transparency.
I guess Corel is flattening the transparency ? - Do i just need to print the file and at some point choose to keep the transparency instead of it being flattened ? If so, where do i find this to do it ?
I can do a pdf file for you all to see what outcome I am getting if this helps, if you could tell me how best to upload it on this forum?

I resolve these similar problems - from Corel into pdf, in this way: Firstly, I export the file from Corel into jpg or tiff, secondly from jpg into pdf.
Thanks Jised, I am having a play with this method - it works great for our proof but for our large format printer the resolution is too small so we do not get a good enough quality finished print. (i am going to try exporting as a tiff with the res to 1200 but this creates a big 380mb file)
but, like i said for our proof for the client this works great so thanks again.

Hi Sammi,
Export it as a high resolution TIF at correct size. I would use LZW Compression if your RIP supports it.
I find going the HiRes TIF rout is the only reliable way to get images with special effects to print correctly.
I run into this a lot, as we get files from China that have all kinds of problems with embedded unsupported fonts, ect. The weird shadows show up pretty regularly when we get magazine ads, especially when originally done in Illustrator, or when I depend up COREL X13 to interpret a complex pdf of an ad done in a later version of COREL or AI. No one solution always works, so far, but flattening the image so that the shadows or "glows" become part of the bitmap usually works. Sometimes I save as DRAW 10, reopen in 10, and then create the pdf from there, altho then there are other problems on occasion, like color drifts. Ole objects are also a real nuissance, as they work sometimes on one machine and other times on other machines will totally glitch the pdf. It doesn't do any good to try to fix the source, as they don't speak English, so it adds a certain challenge to the work.

What type of large format printer?
Is it driven VIA a RIP?
Hi David, we have an Epson 60inch wide printer and its run through Postershop Onyx RIP
and thanks for the extra advice Ronny and Nasko, very helpful once again :)

The advice you have gotten for flattening the transparency is good I have PosterShop also and it has issues with Adobe and Corel Transparency.
