Hey all, been a while....
Can X4 natively export to PDF?

Yes and there are issues for different work flows. For example power clipped duotones shift to RGB, native color PDF creates a color shift to RGB when output to Onyx and VersaWorks RIPS. Metadimentions has trapping issues with transparency when published from Corel but not from Distiller.
Also, you can't use te imposition and other features of the Print preview for create a PDF using Publish to PDF. If you need it, you must create a Postscript file and convert to PDF using Acrobat Distiller

Unfortunately this is an indication that the service provide has little concept of the process, i expect that the issue was the service providers all along.
Corel CANNOT embed a profile in the PDF file. Corel works on two principles, convert color upon publishing and as an assumed color space. What this means is that Corel will convert colors to a selected color space based on the profiles selected in the main color management dialog during PDF publishing process. There are two methods of RIP color handling, all plate/film setters work on postscript color management and require no ICC profile information for source CMYK files, they will assume their default RGB source profile or need to be set to match the source RGB space for proper conversion. All ink jet or digital composite print devices need to have their source profile set to match the profiles used for the creation of the PDF document.
Your color management setting in the main color management dialog are in my opinion incorrect, go to www.coreldrawpro.com there you will find my book on Corel color management it will explain all you need.
Hi David, thank you for your answer, I have shame because, I've bought your book this summer but never get the time enough to read it deeply. So shame on me !!
Check page 57 and make sure that you double click the RGB icon and set the rendering intents to perceptual.
Thank you David, your book is a true usefull source of informations ! It's a complete study and explanation of all the possibilities of the color management options in Draw and Paint.A very great book that all professionnals working with CorelDraw should have absolutely! (on all, should read too, ha ha ha !) Sorry to the community to not reveal what the page 57 contains... hum maybe you could spend a little amount to know it, it's worth it !
Hiiii Ariel, Happy to see you in this thread , thank you for your help. I was a bit afraid because this has arrived on 2 of my jobs (different printers) and I thought it could be a catastrophe for me. The plugin EnfocusPitStop is an interresting plugin that I didn't knew. Do you think it can keep the integrity of the colors ? What do you do with?

Pitstop does not keep the information, is a software for diagnose and editing the PDF files. For example, you can change a CMYK color to Pantone, or a RGB bitmap to CMYK or grayscale, delete portions of the contents, and much more. But Pitstop does not improve the contents, only change something if you decide to change it. Anyway, it's a good program to be able to diagnose errors and to find problems
Ha Ok, Good soft anyway ! I discover something great today, did you know Ariel that it's possible to vectorize the fonts that are included into a PDF file? With Acrobat Pro 8 or 9 only (maybe 7, I don't know), It's possible ! just have to integrate any filigrane (other pdf file) to generate transparency in the background.Once done, it's activate a tool : going in advanced options, print, flatened view, and then check "vectorize all the text". It's a bit complicated (I don't know why Adobe didn't a simpler way for this) but very efficient when you have a customer who hadn't given his fonts.thank you for your advises...
If the fonts are included ("embedded") in the PDF file, there is no needed to vectorize the fonts (convert to outilnes = convert to curves). All that you need is included in the PDF. If you have created the PDF from CorelDRAW using "PDF for pre-press" or "PDF X/3", you will not have problems
Anyway, you can also use Pitstop to convert text to curves
About the problem with your image:

the answer is simple: when they placed the PDF into a Quark file (sometimes, most RIP have problems with PDF and it's needed to print the PDF from within other application) and send a Postscript file (or perhaps, create a new PDF using Acrobat Distiller) they have overwritten the color profile values.
