Hey all, been a while....
Can X4 natively export to PDF?
kumorigoe said: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
Ariel said: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.
is this maybe what is happening with others who have commented on washed out output from PDFs? how exactly would Quark overwrite the parameters in the PDF, especially when the profile is the default CMYK, nothing special. it's either going to be CMYK or RGB. all i can see is that CYMK will provide a general onscreen softproof representing what the RGB>CMYK conversion is going to produce. what this creates is a somewhat desaturated appearance. are you suggesting Quark is applying another CMYK conversion to the already CMYK, resulting in further desaturations?
Hallo,
i have made a test with Quark. I think the pdf setting (1.7 Acrobat 8) is the culprit. I only use PDF-X3 or PDF-X1 settings in Corel.
Ariel : I sometime need to use PDFs that come from customers. I import them in CorelDraw for jobs or other staff.Sometime too, serigraphic printers use the Pdf I send to them to import in there applications, they allways ask me to have vectorized fonts, but sometime I can forget this, so it's good to have solutions as Jeff told . Carlos, I suspected the (1.7 Acrobat 8) CorelDraw savings to make troubles with Xpress, that could confirm my suspicion...
Just To had an other bad experience with PDF filter exporting : I just saw that some little ojects was well interpreted in the old compatibility : Acrobat 8 and are very bad interpreted in the PDF/X-3 filter export (aleasing)

which size has your text or image? can you send me the cdr file to test? seems that it converts to bitmap, that is one of the options in the Publish to PDF menu
Hi Ariel, again thank you again for your help !

The problem is simple to reproduce : Draw a circle, then draw a red square that you transform in bitmap image (dpi doesn't matter) Put it (clipboard) inside the circle and then Publish a PDF do it with PDF/X-3 compatibility, then Publish the same PDF but only change the compatibility to Acrobat 8. here is the result : Of course I tested it on X3 and the problem is not present.So it's a true problem in X4 with this filters.
I don't know what to do with this problem, it's visible on the productions...
To all those who have posted here, I have written extensively on PDF output for CorleDRAW in the CorelDRAW Pro magazine and have professional level tutorials. I have been using exclusively PDF work flows for years, PDF, portable document format, means what it says if your using Corel published PDF you have a limited work flow, it works some places and not others. If you're serious about a PDF work flow you will need to use Distiller published PDF. You will also need to create your file in a postscript compliant manner, that definition changes with the quality of the RIP being used. However creating universally compatible PDF files from CorelRAW using Distiller is quite possible.
David, Yes it's possible, as you say, to print with distiller, but trying by myself with Acrobat 9 Distiller, here is the result :
Distiller or Publish to PDF, it's completely the same problem.Maybe some options that I don't know in Distiller can avoïd this? Unfortunately, I don't know them...To bring a correction as I told before that X3 had'nt this problem with PDF/X-3, in fact it has!

The problem is most likely that you're using non-postscript compliant file creation techniques. The transparency bounding box may be the issue. Please e-mail the 40 sample to davidmilisock@comcast.net I'll play with it and send it back.
Hi, Finally, I found what's wrong with CorelDraw X4 ! Searching and playing with powerclips and bitmaps, I found!Bitmap Objects that contain transparencies make aliasings (or holes along the edge if you prefere) when placed inside a powerclip and exported in PDF filter X-1a, X-3, and A-1b. The solution is to flaten the bitmap and thus delete the transparency (note that a bitmap can contain a transparency that you don't see) the only way is to flaten the bitmaps that are in Powerclips.To understand better the different PDF formats, I could advise you to see the FAQ of the the Ghent PDF Workgroup:http://www.gwg.org/content/downloads/whitepapers/PDF/GG_FAQ_PDFX_EN.pdf
For my side I think that PDFexported from CorelDraw can make big troubles with colors, depending of the specifications of the printer, press desk, software that is received it, and depending a bit of my unknowledge too ;) Working with multiple colorimetric spaces, it can be hard to provide a compatible PDF.I'm trying currently Pitstop from Enfocus, to verify and certify the PDF I make with CorelDraw. I do test with it and it's rather good because it prevents you of errors and can replace the colorimetry...
