• There is no good print with bad prepress files

Document naming convention

Naming your files according to these guidelines makes it easier for Grafostil to meet your expectations of a quality job. This means the right version of the right page, in the right place in your publication.

• File names should only include alpha-numeric characters (a-Z and 0-9), underscores (used to separate sections of the file name), and periods (used before the file extension ".PDF", ".PS")
• Special characters, including but not limited to, diacritics glyphs, asterisks, ampersands, slashes, dollar signs and brackets should never be used.

• Theses are illegal characters ( ˜ ´ ! @ # $ % ^ & * ( ) + = { } [ ] | \ ; : ” ‘ < > , ? / )

• File names also must not exceed 30 characters without the date and identifier.

If your company name is Big Publisher INC and your book name is Herman Melville Moby-Dick, soft cover book with bellyband, use this convention

Date_CompanyNameShortAsPosible_InitalOfWriterBookName_PrintSectionIdentifier

So your supplied document will look

20190511_BigPub_hmMobyDick_CI.pdf
20190511_BigPub_hmMobyDick_COV.pdf
20190511_BigPub_hmMobyDick_MSC.pdf
