GUIDE TO IMAGE RESOLUTION

RESOLUTION refers to the number of colored dots or pixels that make up an image. It is commonly expressed in dpi or dots per inch.

RESOLUTION RULES-OF-THUMB:

  1. The higher the dpi, the greater the resolution, the better the image quality. Higher resolution images create larger file sizes.
  2. Image resolution is directly and inversely proportional to an image's physical size. When you increase the resolution of an image, reduce its size.
  3. When you enlarge (inches) an image and lower the resolution (dpi) the image will print poorly.
  4. For printed images, the ideal resolution is 300 dpi at the final printed size.

Here is a chart to help you determine the proper dimensions of your image at your desired print size and in the recommended resolution of 300 dpi.

More Hepful Tips

  1. Your screen resolution doesn't accurately reflect your image resolution because monitor displays usually have about 72 to 96 ppi. To view the print resolution of your image, zoom in up to 300 - 400%.
  2. When taking pictures from a professional level digital camera for your print project, it's best to set your camera to the highest resolution L smooth jpg + RAW setting.
  3. Four-Color Process Print uses the CMYK swope 2 color mode. Convert RGB images to CMYK using graphics editing software such as Adobe Photoshop.
  4. Save and transmit your photo images in a lossless file format such as tif LZ compression or eps to maintain accuracy and quality.
  5. Save art files with bleed allowances and finish crop marks and transmit art file as PDF (will reduce transmittal file size).
