Thomson-Shore will accept print media on the following:
Please collect all your text and cover files to include, graphics and fonts. Load them on your removable media and send it to your Customer Service Representative.
File Submission Problems:
One common problem when providing files is missing fonts and graphics. Please make sure that all fonts and graphics used in the layout(s) are sent with the job.
Another common problem we encounter when receiving customer files is they often are Mac files, copied to a PC and then transferred to a file storage media. The problem with transferring Mac files to a PC as an intermediate step is that all the resource data (crucial to Mac files) is stripped out by Windows. When prepress receives the files, they've lost their file type and creator, and if they don't have an accurate file extension, we have no way of telling what kind of files they are. This is most common with fonts which are completely dependent on their resource information and are useless without it.
So when collecting your files avoid transferring Mac files through a PC, or at least use correct file extensions and always zip or stuff your project before transferring it.
