To ease file prep woes and to ensure a smooth production transition from file to plate, it is a great help to all to give your files one last review before submitting them. The first few things to make sure is that your file’s artwork is set to the right dimensions, that you’ve checked your artwork to make sure all plate type line minimums are met, that your file is in the proper color mode or image mode and that your file is in the proper file format and extension.
When working with a file that requires multiple colors for separations, please make sure all objects are assigned to their appropriate Pantone swatch or spot color. Adobe Illustrator and InDesign are excellent programs for setting up and checking such files.
Please also remember to check out any other file prep questions to answer any unresolved questions that you may have.
