Export InDesign CS5 file for Corel Draw
I'm sometimes giving small adverts that I created in ID CS5 to a local newspaper. They are building their stuff in Corel. They usually want me to either give them an image (as in jpg) or a pdf file. They don't know what to do with the InDesign file. I've got the feeling that they are actually recreating my stuff in their program, which I don't like at all.
Is there a common file format that both programs can read (or that mine can write, at least)? I don't want them to redo my work, which wastes their time and is error-prone.
PDF is the appropriate choice. You can either "export to pdf" directly or use the PDF printer driver (if available) to create the PDF, but either way, ensure:
1) font embedding is enabled;
2) use one of the default presets such as "High Quality Print" or "Press Quality" (don't use "Standard", web, etc)
PDFs are basically fixed files which preserve vector information and maintain color spaces, etc.
JPGs are a poor choice because you are fixing the resolution on export rather than having the print provider fixing the resolution at plate time. Also, JPEG compression is lossy by nature. Both of these properties are detrimental to set type.
