Digital Files in PDF format are accepted for display advertising, but they must be created in accordance with the Printing Specifications below. Failure to follow these guidelines may result in an ad that includes reproduction errors (such as missing or illegible text, font substitution, missing graphics, or color quality problems), or an ad that cannot be printed at all because of PostScript errors.
These printing specifications apply to the following print publications: Rappahannock Record, Southside Sentinel and The Rivah Visitor’s Guide. They are designed to ensure that your advertising will be published accurately and with optimal reproduction quality.
All products are printed on a high-speed offset web press on standard newsprint. Our prepress environment is entirely Macintosh based.
Line Screens, angles and halftones specifications
— Digital files will be imaged at 85 or 100 line screen
— Press Dot Gain: 30%

— Digital halftone highlights should be 1 to 3%, maximum shadow 88-90%.

What is PDF and why do we use it?
PDF (Portable Document Format) provides a standard way for digital files to be shared between designers and printers. PDF files include all of the images and fonts necessary to print the ad, are cross-platform compatible (Mac, PC or Unix), minimize file size, take less time to transmit electronically, and protect design integrity when the ad is imaged.
If you do not have access to Adobe Acrobat Distiller (version 4.0 or higher), have an imaging service bureau convert your file to PDF. Digital files in PDF format are accepted on disk media or transmitted electronically.
How to make a PDF file
1. Create the original ad file, using your favorite software, and follow all the Printing Specifications above. Remember to change all spot, RGB or LAB colors to CMYK Process for color ads or Black for black and white ads, before making your PDF.
2. Some newer versions of software are able to make PDF files directly. If you have this option available, follow the software instructions to make a PDF file using the preferences listed in Step 4 below.
3. Print the document (as a composite) to a PostScript file. It is essential to embed all fonts in the PostScript file (not just subsets).
4. Use Adobe Acrobat Distiller (version 4.0 or higher) to turn the PostScript file into a PDF file. Set the default preferences in Acrobat Distiller as follows:
— Compression: Change both Grayscale and Color Bitmap Images Downsample to 180 dpi.
— Fonts: Embed all fonts and subsets below 100 percent.
— Color: Turn off options Convert CMYK to RGB or Convert all colors to CalRGB, depending on the version. Make sure Leave Colors Unchanged is checked.
