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
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.
Your method makes sense especially in todays environment. Technology today should have us creating output of the highest quality however the print industry has for a large part developed a malaise of mediocrity unsurpassed in print history.
In order to use high end features at most shops I literally have to go on-site to meet with senior management and in several cases I had to meet with the print shops technical service provider.
When quality is paramount matching TIC to the press and the media, understanding color shift using various coatings and the difference between (as an example) Global Graphics, Agfa and Meta RIPs is a must and the local technical staff today in most cases has little knowledge. In fact I once ask a pre press technician what the T8C was for his ink linearization dot gain curve was and his eyes glazed over, looking the the processing indicator in Windows, he then said, I push this button here.
The reality is that once all the details are handled a premium quality 6 color over 6 color print job costs no more than a crappy 6 over 6.
