Submitting your native art files to commercial printing company (such as an Illustrator, InDesign or Photoshop file) can be frustrating for both you and the printing company. If you want them to make edits to your design they may need the native files to make the changes, but in most cases you just want them to print your order. First, before sending the native art, all of the images your used in your art must be imbedded (not linked). Additionally, you must gather and supply all of the type fonts that you used in the document, as they may not have some of them. There are also potential compatability problems uless both you and the printer have the same verion of the design program. Additonally, fIle sizes can be very large, so you may not be able to send the files by email, and will need to transfer them thru an FTP site, such as DropBox. In the SAVE AS or EXPORT menus simply look for PDF as one of the menu options among the format options. For the FILE >, PRINT option with the “General” tab selected, look in the list of available print devices (such as PDF or PostScript file). The first step is to determine the quality of the PDF. In the General tab (highlighted in blue), there are various compression level settings (in Adobe software called the Adobe PDF Preset). Choose “Press Quality” when making a PDF for professional printing. DO NOT choose “High Quality Print”, as that setting is for your desktop printer (the quality level is too low for commercial printing). You may have noticed there is a preset option in the list to the right called “Press Quality +” that is not available in your job options list. It is a custom Adobe PDF setting used at Summit Printing for extra high-quality PDF files (since many of our products print at photo-quality 500 dpi). If you would like to install it, we have provided it for download at no charge. Choose File >, Print from the top menu. Select the Marks and Bleed tab. In the Printer selector choose PDF In the PPD Selector, Choose Adobe PDF In the Marks section, check “Trim Marks” (some dialogues say “Crop Marks”) In the Bleed section, un-check “Use Document Bleed Settings.” Set the bleed to 0.125″ on all four sides. Note: if the units are not in inches, it can be changed in the preferences section. Depending on your software, there may not be any more important selections to make, and you are ready to save your PostScript file. Once you have your finished PostScript file, open the Adobe Distiller and choose the Press-Quality job option and select your PostScript file to be processed into your final PDF print production art file. Some programs may have additional options allowing more control over the PostScript / PDF job options. The screen-shots below are from the Adobe Illustrator print to PostScript file job options: Some programs, such as Adobe Illustrator, may display your “raster effects resolution that control the quality of drop shadows and other special effects that were applied in their software. Select the Graphics tab Make sure a minimum of 300 DPI is specified. Illustrator allows a custom setting, which we normally rez-up the to 450 dpi for CMYK documents. Source.
