Send fonts and links when sending native design files. Go to “File” > “Package” to have the software gather up links and fonts.
When sending a PDF make sure it is “print ready”. This means high resolution, with 1/8” bleeds, with crops, and with all fonts embedded.
Do not build files with spot colors if the intent is to print standard 4 color process inks. Only build files with spot colors if you are purchasing a PMS ink.
If you are not designing a book, be sure the “Facing Pages” box is unchecked.
Always send PDFs in single pages. Never reader spreads or printer spreads.
Photographs and images should be 300ppi and CMYK color mode.
Blacks should be 100% K, never use Registration Black.
