Hi All,
Love Corel, but only know the basics I guess.
I have used a bevel effect on a company name for a banner (3m x 1m). When I publish it to .pdf the bevel effect is extremely pixilated. I have made the bitmaps (in .pdf settings) 600dpi to try and help, but this does nothing.
I can only use .pdf on our printer RIP....
please help!
Thanks in advance.
Options > Document > Page Size (or double click the page frame), there's a setting called Rendering Resolution.Bevels will be rendered, and so will transparencies and drop shadows, at the resolution specified here.You can also convert effects and other things that may cause problems to a bitmap (flatten) before sending to the RIP.Just don't forget to save a copy (on a separate page perhaps) before you flatten, in case you need to go back and edit.
For a banner that size, I guess around 100 dpi will be good enough (maybe even lower) but check that setting and come back to us.
Another thing: See if your RIP will accept Acrobat level 5.0 (version 1.4) or higher. These versions support some effects better (shouldn't be any difference with bevel though).
I use RasterLink myself and publish to PDF Acrobat 6.0, even though I don't think RasterLink officially supports it..
Hello again,
Just checked the rendering res on page layout, and it's set at 300dpi?
I tried it at 600dpi and still the same? i have the res in the .pdf settings at 600 hoping this may help too.
How do I flatten before sending to the RIP?
Yes, I use acrobat level 5 as well - smaller files and the effects seem to work better.
Thanks again.

Have you tried breaking your bevel apart from the guide text just before export? That way it becomes a stand alone object with a set resolution.
DON'T save it that way. Do it just before export only.
Hi Mike, still the same result... :-(

Can you upload the cdr file?
(if you've not done that before, when you hit 'reply' choose options tab and then add the file.)
If it is too big, strip out the file and leave just the bevel and text. and try again.
Hi Mike,
File uploaded. I have deleted the paint tin graphic... I also had a separate drop shadow on the "Unique Painting" had to delete it as the file was up around 5mb.
Thanks for your help...

I had a look at your file and even though I didn't have the same fonts installed I managed to get the same result you did.First time I Published to PDF, only part of the text was bevelled. Next time I got bevel on the entire text but it was heavily pixelated.My guess is that you exceed the 30,000 pixel limitation for the bitmap (which it will be when exported), and therefore there's an automatic downsampling, or as in my case, the bitmap will only be rendered partly.
Workaround: I mentioned in my previous post that flattening may be the way to go, and I suggest you try that. Not only in this case but also with other files where effects are involved. Sometimes the effects come into the RIP just fine, but you get much better control over the output if you convert the tricky parts to a bitmap prior to exporting.
Basically; convert all effects to one or a couple of CMYK bitmaps (maybe even to one big bitmap including the background), BUT leave text and vector objects on top of it AS VECTORS.
In this case (without having seen what the background looks like), convert the bevel to a, say 100 - 150 dpi, bitmap. You mentioned drop shadows and it is possibly a better idea to convert the bevel, the shadow and the background to one bitmap, and then leave the other stuff as vectors on top of it.Your banner is 3,050 mm, which equals 120", and you should be able to create a bitmap at nearly 250 dpi in that size, but it is not necessary. 150, or possibly even 100 dpi, will be more than enough.
As I also said; Don't forget to save a copy of the original before you start flattening.
And finally......you may try to change the rendering resolution like I mentioned at first. Use 100 dpi to keep it well below the 30,000 limitation. You may then have to recreate the bevel in order to make the new setting transfer to the bevel. Change some setting, like 7.0 mm to 6.9 mm, hit Apply and then back to 7.0 again.Then try to make a PDF again. Worked in my tests and the resulting bevel looked fine.
