Commercial printing is a meticulous job and requires perfection in each step, especially in pre press stage. This is the most crucial stage as it determines the precision till the end stage. Therefore, the file is passed through various and many processes including manual process before it is finally issued for printing. Manual checking is quite difficult as every bit of the file is necessary to be accurate and up to the mark. Here is the prepress check list of the file to be checked manually:

•    Ensure that the all vital content is within safety margins
•    Verify if the process colors are CMYK  and not RGB
•    Check and edit the colors if needed
•    Dispose unused color sample cloths
•    Make sure that spot colors are changed to CMYK or if needed, carefully define and apply them as spot.
•    Verify the font in the file and edit them using Quark’s “Usage” menu item or Adobe’s “Find Font” menu item
•    Check for missing or inactive fonts
•    Make sure that the fonts are styled in their “original” form, means they are not modified by artificial  “italics” or “bold” options   in the application
•    Verify linked graphics to ensure that they are updated.
•    Clean up the file by deleting empty boxes, unused elements and elements on the pasteboard.
•    Verify layers.
•    Make sure that the template layer contains only template elements.
•    Check that artwork layer contains only artwork.
•    Check if the template layer is set to non-printing or is turned off.
•    Develop a colored proof document to check color quality, layout and spelling in the file.
