I am publishing a book, the contents are in MSFT Word doc and the book cover art is in a jpg. I need both converted so the printer can use the material. The printer company is Lightning Source. Do you have experience doing this for both content and book cover art? Please let me know or send me a referral to someone who is experienced and not expensive. Creating a PDF / What is PDF/X-1a:2001? PDF/X-1a:2001 is designed to provide a reliable and stable PDF for printing purposes. It requires that the color of all objects be expressed in CMYK or spot colors, prepared for the intended printing conditions. Elements in RGB or Lab color spaces or tagged with ICC profiles are prohibited. It also requires that all fonts used in the job be embedded in the supplied PDF file. This file format is the most compliant file type for LSI’s printing purposes. It addresses most issues that prohibit your file from printing. This profile was established specifically for the printing industry. LSI requires all cover and interior PDF files for Color Interior Books be PDF/X-1a:2001 compliant. LSI recommends that you print to a PostScript file first, then processing the PostScript file using Adobe Acrobat Distiller Professional version 6 or newer. This allows you to produce a solid and stable PDF that is ready to print.
