http://www.dbman.com/Requirements for documents to be printed on a press are not the same as those used on the web. They need different color, better resolution, and certain other things that aid the printer in setting up the press.
Graphics and Color:
· Color for graphics, background colors, etc. must be CMYK (Cyan/Magenta/Yellow/Black) and not RGB (Red/Green/Blue). RGB is based upon light and is used on a computer monitor. CMYK is based upon pigments and is used for the ink used in the printing process. Using RGB on a printed job will make the colors come out wrong. Converting RGB pictures to CMYK is an easy process in Adobe Photoshop or similar program: just change the mode from RGB to CMYK.
· Do no use color profiles in graphics. A color profile is specific to a particular printer and the colors will not come out right on a press. This is also very easy to do in Adobe Photoshop: just Save As and make sure the color profile box is not checked..
· Use at least 300 DPI resolution for graphics. Anything much lower will not print well. Especially do not take graphics from a website. These will usually be only approximately 72 DPI and will look terrible when printed.
General Consistency:
· Place page components such as running heads, page numbers, etc. consistently from page to page so that they don’t appear to move around as pages are flipped.
Aids to the Printer:
· Add crop marks. These are horizontal and vertical lines that show where the edge of the page is so that the printer can cut the paper to the correct page size.
· Any background picture, color, or tab that is to show on the edge of the page needs to “bleed” past the trim; typically ¼" but some printers require a different amount so check with them.
· Always keep anything (type, pictures, etc.) that does not bleed past the trim at least ¼" away from the trim. This gives the printer a margin of error for cutting the paper and some extra room in the event that the pages need to be cut smaller (undercut); for example: to reduce the weight of the printed piece to save postage.
