About Image Resolution

featured-image-5
Resolution is the measurement of how many dots/pixels per one inch. The higher resolution, the sharper the image will be. The recommended resolution of 300 dpi (dots per inch) will produce crisp, clear results. Lower resolution images can appear fuzzy, jagged and blurry.

good image resolution

Resolution / Zoom of 300 dpi  – Will print well

bad image resolution

Resolution / Zoom of 72 dpi – Will not print well
400 dpi text resolution for printing
Resolution rules:
  1. Images should be 300 dpi.
  2. Images that includes text should be 400 dpi.
  3. Resolution and image size are inversely proportional to each other. If you make in image larger, the resolution will decrease. If you reduce image size, the resolution will increase.
  4. Low resolution images print fuzzy, jagged and blurry. Like in the 72 dpi example above.
  5. The settings that are used when the image is “captured” for example, taking a photograph or scanning an image, will determine its base resolution. From there resolution can only be improved by decreasing the image size.
  6. The recommended minimum resolution for printing is 300 dpi. Whereas computer monitors generally have a display setting of 72 dpi. Therefore some images may not look bad on your monitor but are not likely to print well.
Things to avoid:
  1. Web images are predominately low resolution GIF or JPEG files. This resolution is good for downloading quickly form the internet, but is not good for use in printing. Therefore do not save images or graphics from a website to use in your print project.
  2. Upsampling is a term used when a low resolution image is saved to a higher resolution without changes to the dimensions. Upsampling will add more pixels/dots per inch (dpi), but will create blurry images, ugly blocks of color, and high contrast in images. The only solution to this problem is by decreasing the image size or of course, , by recapturing the image at a higher quality setting.
