 Lange Graphics bases its PDF file requirements on the PDF/X-4 standards with just a few exceptions. You can create Adobe® PDF files from almost any application, using a wide variety of settings and features. But to successfully exchange those files to achieve the expected results, it helps to have a set of agreed upon parameters. The PDF/X standard, eliminates many of the color, font, and trapping variables that could cause printing problems. PDF/X makes it possible to deliver files ready for print production with the highest possible confidence that they will print as you intended.
    The quality of the final PDF file will only be as good as the quality of its source components. Ensure that the original source file contains the correct content and form, including proper image resolution, linked fonts and images. Good vector-based clip art, high quality stock images, and fonts from reliable, reputable foundries will yield higher quality output. Proof carefully for content and formatting before creating the PDF. If available, use preflight features to identify missing fonts, and unlinked or low resolution images.

Some guidelines to follow:
1. Fonts
    Adobe PDF fully supports TrueType, OpenType Multiple Master, Type 1 fonts, and most CID-encoded (double Byte) fonts. If you and your customers use high quality fonts, there should be no reason to restrict these fonts. To minimize the chance of errors when editing or printing PDF files, embed the fonts in the file. Check with the end user license agreement to avoid using fonts that are unreasonably restrictive about embedding them into the PDF.

2. Images
    Be sure to convert all RGB images to CMYK and have at least 300 resolution at the final output size. Also images that have a total ink percentage of all CMYK over 310% may cause problems at the press. Attention to these details will help to eliminate any unwanted color conversion and resolution problems at output.

3. Transparency
    In general, it is best to leave transparency unflattened in your artwork. If flattening is necessary, Lange Graphics will use the appropriate flattening resolution at output. If you choose to flatten a transparent object, select the highest quality settings, and pay special attention to spot colors that will have to be converted to CMYK.

4. Spot Colors
    In order for your file to separate correctly at output, be sure that all spot colors are set as spot and not as CMYK builds. Be sure that all PMS colors are named the same so they don’t get separated to a CMYK build.

5. Document Setup
    Documents used to create a PDF should be created as single pages and to the final trim size. Spreads are not preferred as they create problems when imposing your file. Be sure to include at least a .125” bleed, this will insure the artwork will continue off the page when it is final trimmed.

Keep in mind, using the PDF Workflow is a more efficient production workflow, but it will limit Lange’s ability to correct your file. To correct your files , you will need to furnish new PDF’s for any files that have alterations to them.
