JPEG or TIFF

The JPEG file format has gained prominence over the past few years, in large part due to its ability to provide a fairly high-quality image at a fraction of the size of other formats, such as TIFF. Of course, that benefit comes at a cost. JPEGs save disk space by eliminating some of the subtle color changes not readily apparent to the human eye. At a minimal compression setting, those changes are fairly hard to see. The higher the compression, however, the more of those changes are lost, and the blurrier the image becomes.



Here are some tips to remember when working with JPEG images:

• Start at the top. If you’re taking your own digital photos, set your camera to its highest-quality JPEG setting. The images will come out larger, but the quality will look sharp. For photos when print quality is especially important, set the camera to save images as TIFF files, if that option is available.

• When editing an image, consider saving it as a TIFF, instead of a JPEG file. TIFF files are larger, but will not lose any quality or clarity when edited and saved repeatedly. JPEGs, on the other hand, will lose a small amount of quality and clarity each time they are saved.

• When image quality is critical and you need to use a JPEG, set your image editing software to save it with the least compression possible. The image will lose a subtle amount of clarity, but not enough for most people to notice.

Preparing Files for Print

If you design your own marketing materials, successfully preparing your files for print production can not only save you time and money, but will also ensure your final product is exactly what you envision. Here are a few tips on how to prepare your files for print: Include a listing of all contents used in your file, such as fonts and images. Save your files with explicit, useful names. Include high resolution (300 dpi) images and make sure the images are linked to the images used in the document. Modify images in a photo editing program before placing them in a layout file. For example, if you rotate an image, rotate it in Photoshop before you place it in Quark or InDesign. Check your printout for text flow issues and bad text breaks. Include all font styles (bold, italic, etc.) for every typeface used in the project, not just the individual font. Use exact measurements and guidelines to ensure accuracy. Include registration marks for bleed trims. Define the size of the document to m

Pack Extra Meaning into Your Message with Strategic Color Combinations

Of all the elements of design, color is probably the most challenging to understand.  Color originates from a light source that is viewed directly or seen as reflected light. While colors can be displayed in spectrums, prisms, or contrasts, the power of colors is not only in their arrangement, but in the way we perceive them. Want to add depth to your message? The colors you choose can add an extra layer of meaning. Colors Prompt a Specific Response According to Sally Augustin from Psychology Today, research shows that particular colors can prompt measurable responses .
