your pdf ad to us. Even though your ad may look fine on screen, it may not print as you expect it to. A hardcopy proof generated from a 1200 dpi laser printer will give you a closer idea of how your ad will look when it goes to press. BLACK DENSITY AND DOT GAIN IN HALFTONE IMAGES Since there is no absolute mathematical setting for tuning halftone images (TIFFs are typically used for print) so they translate well onto newsprint, we can only offer you a starting point. With experience, you will be the best judge of how to properly adjust your own images. UNADJUSTED Top black value set at 100%, which is too high, leaving no room for dot gain (the bleeding or disfiguring of halftone dots that occur when ink is applied to paper). ADJUSTED Top black value set at 90%, is a good starting point for image quality. After making a proof from a 1200 dpi laser printer for yourself, you may also opt to tweak the high- light and midtone values. RESOLUTION FOR HALFTONE IMAGES AND LINE ART ACCEPTABLE RESOLUTION Halftone resolution 200-300 dpi Line Art resolution 600-1200 dpi UNACCEPTABLE RESOLUTION 1 Poor Halftone Image The poor, pixelized quality of an image is due to the image being low-res (a 72 dpi JPEG pulled direct- ly from the internet, for example). Also the image must not be enlarged, which ads to its poor quality. Halftone images should be at least 200 dpi and imported at 100%. 2 Poor Text Having low resolution (150 dpi) or having saved it as grayscale. Making a PDF via Photoshop will often ren- der such result. 3 Poor Line Art The combination of low line art reso- lution of less than 200 dpi and enlargement of over 120% account for jagged, pixelized edges. Line art images should be at least 600 dpi and imported at 100%. BACKGROUND IMAGES AND LEGIBILITY If you choose to screen an image behind type, keeping the art simple and at a 10-15% density maximizes legibility. BACKGROUND IMAGE TOO BUSY If background art is too busy it may obscure text legibility. Also, the body typeface should be large and bold enough to stand out. BACKGROUND IMAGE TOO DARK Background image should not exceed 20% density. BLACK AND WHITE four color Four-color ads should be submit- ted as composite Acrobat PDF files via disk or the BCN WEEK Web site. Four-color ads should be submit- ted well in advance to allow time for inspection and, if necessary, correction. IMPORTANT 1 Since there can be multiple pit- falls in 4-color ad preparation, please consult a professional if you are at all unsure of the pro- duction methods. 2 The final ad should be cropped to the active area only. There should be no additional white space or extraneous information bordering the final PDF. 3 Registration marks are not required with the color PDF com- posite. When we place your ad, registration marks will be added. 4 Even if you are sending via BCN WEEK’s website, it’s a good idea to send a hard-copy color proof to us. 5 Make sure art is saved as CMYK (not RGB or in Pantone spot color mode). SPOT COLOR All production recommendations for black-and-white ads apply to spot color (black plus color) ads. Spot color ads should be submit- ted as both composite and sepa- rated Acrobat PDF files via disk or the BCN WEEK website and should be submitted well in advance to allow time for inspec- tion and, if necessary, correction.

SIMPLICITY WORKS BEST Overdone color has the same adverse effect as all text being all caps and bold. If everything is emphasized, nothing stands out and informational hierarchy is lost. Use color sparingly to highlight important pieces of information. QUALITY ADVICE In addition to providing BCN WEEK with a hardcopy color proof, we highly rec- ommend that you run test separations before sending your final ad. Hardcopy test separations work fine. Also, Acrobat 6 has separation and overprint preview functions that help more accurately predict how your ad will print. Week B C N
