(Publisher) Problems with PDF-Export

[seastar708]

Hello,

since any years, I´m working only with the Serif- and Affinity Software. My newest is now the Affinity Publisher, for creating flyers and other printing papers. For the printing office, I´ve export my project with 400 dpi into PDF/X-4, with CMYK and the colour profile FOGRA 51 (PSO coated V3), what the office needed. I´ll sent this to the office and they answers me permanently, that the file had a to low resolution (220 dpi instead of 250 dpi) and it´s in RGB instead CMYK. The complete design was made with Pantone+CMYK coated. 

I´ve made many different versions and the result is always the same and I don´t know, whats the cause it. It is very urgent for me, to find the mistake, than I must send the correct files to printing asap. But my customers doesn´t actually  allow me, to upload the flyer in a forum. 

I´ll be glad about helping and eventually in German, too. 

Thanks to all

Works here on first try. There are many reasons for a possible failure (source resolution, document resolution, document profile, output configuration). So nobody can say what is going wrong without a sample .afpub file. (Don’t tell us, you aren’t allowed to upload the file! You can build an equally behaving example file or modify the existing one within minutes!)

Thanks, but I had called the printer office again. And there was finally an expert. He said, the cause of the problem are the pictures. I´ve exported them to TIFF-Files with CMYK, so that is all ok now. About these theme I didn´t found information at the integrated help function. But my problem is now detached. Thanks for helping.

Importing images as CMYK is a solution, but not the real(!) reason for your failure, because it has to be possible to import RGB images. In this case you have to check the option „Convert images color space" in the „More“ section of the „Export“ panel.

And: Converting the images doesn’t solve the output resolution issues, you’ve been talking about.

At first, thanks mac_heibu for your help. But - it is possible to import JPG in the Publisher, but my printing office, needs these pics in CMYK. So I´ve exported this with Affinity Photo into TIFF (CMYK). These pics I´ve set in my flyer (Publisher) instead of the JPGs and exported my complete project into PDF/X-4. After testing from the office, my files was now ok and they will be printed. And so I´ve learned by doing, how so often.........
