Image quality

Image quality example

So what is the best image quality to print with? Ideally no less than 300dpi for the best print quality, dpi stands for dots per inch so how many dots of the image are within a inch. The lower number the less dots so therefore looks blocky. Jpegs (image file type) do a great job of blending these dots but it still doesn’t help improve the overall quality.

Worth noting that if you have a low resolution file (lower than 300dpi) you can save as a higher dpi but this doesn’t necessarily improve the quality. All you are doing is manufacturing dots from the blend in-between. Also if you have a 300dpi image file if you choose to make it bigger then the dpi reduces, for example if you have a 50x50mm image at 300dpi and increase to 100x100mm then the dpi will be 150. If you are not sure how an image will print try zooming into the image on your device up to 175% if this looks awful chances are your print will too.

When saving your image you want to ensure no less than 300dpi and saving as a TIFF or PNG will create the best result.

The best file type if at all possible would be what is known as a Vector which is an outlined file type such as EPS or Ai. This is commonly used for logos as they tend to be shapes and/or text. A vector is an outlined image similar to that of a wire diagram. As you make this bigger the lines keep their shape but expand. Imagine the expanding plastic ball you have probably seen kids shrinking and enlarging in their hands. This is what happens to the outlines of your design.
