hi, my pdf file is bigger than original Corel document after publishing PDF with preset PDF/X-4:2010. I did everything like last time created PDF, but got different result. What's wrong?
Are you comparing the CDR file size to the PDF in Windows Explorer.
a few times before i used the same preset and had a lot less documents but something has changed even though i haven't changed the settings
I thought, a smaller document size :)
A CorelDRAW file with images and transparency in will (in Windows Explorer) will show a smaller file size then the PDF.
If the file size is bigger after exporting in PDF with preset x-4:2010. something is wrong with software I think. It is not matter of Explorer. I worked with Corel for several years, and for the first time I have problem like this. Is there any solution to refreshing the software?

CorelDraw does a very good job compressing its own file format, so the fact that a CDR is pretty much equal to the size of a PDF is not unusual.But I guess the main reason why the PDF is bigger may be because you are using effects in Draw that aren't compatible with PDF, or the PDF/X-4 format.Transparencies should be accepted in PDF/X-4 but I don't know if there are other things that aren't.If so, it forces Draw to convert these effects to bitmaps, which increases the file size.
thanx Ronny, it is also possible to have increasing file problem because some effects, but I think my problem is with bitmap in document, cdr does not make compression when processing pdf export action. It is good with some tipe of bitmaps, but not good with others. I don't know why?
The PDF/X-4 export settings in Draw uses ZIP-compression for bitmaps (which is lossless but not as effective on size as a lossy compression like JPG), and the downsampling stops at 300 dpi, which means that most bitmaps probably wont be downsampled at all.So I guess you'll have to accept and live with it, unless you can change the filter settings or simplify the original file.
I don't know if this could help but I tend to avoid any compatibility issues when exporting to PDF.My technique is darn near to flawless and I never get any surprises. Any program could then open my PDF files. Of course, this is a FINAL version, absolutely uneditable.Many have different solutions, but this is MY ROUTINE and the simplest way FOR ME to do avoid any issues at all.Here are my steps:PREPARATION• Before doing anything, I have setted my Color Management to PERCEPTUAL redering intent. This way, any bitmap conversion will appear almost identical to what you see on your monitor. I've even setted it to default!• I select every object in my page except flat colored text or vector logos (No gradients).• I convert all these selected object to ONE BIG bitmap at desired resolution and format (RGB or CMYK*)• I then select all text and convert it to curves (CTRL+Q)* Depending on the format of my images sources (RGB or CMYK) I tend to first create an RGB image that I then convert to CMYK afterwards. Sometimes, blended RGB and CMYK images have a tendency to create unwanted color issues if converted directly to CMYK. EXPORTING• I export my file to PDF with the PDF/X1-A:2001 (If I don't need layers)• I export my file to PDF with the PDF/X4:2010 (CMYK) (If I need layers)• If needed, I set up my parameters in the PDF dialog box • Number pages, selected pages or all pages • Native colors, CMYK or RGB • If needed, I set up my Prepress options and add my crop marks setted to the page size of the document.This way, I've never had any compatibility issues, color issues, text issues. NOTHING.
Thanx Stephan for your suggestions,
I will try to do your way.
