Print Information


This photo is saved at 72 dpi, which is perfect for web sites and computer resolution images. It will work great for screen-based non-print use such as web sites, web design or powerpoint templates, software applications etc.

If you do need to print this image, you should download the larger image which is normally available on this page, or alter the DPI of this smaller image to at least 150 or preferably 300 dpi.

This image will print at: 2.30" x 3.00" at 300 dpi

...or at 4.59 inches x 6.00 inches at 150 dpi

if you raise the dpi using a graphics program. We do not recommend lower than 150 dpi for printing or the image will be less clear and begin to appear "jaggy" at lower dpi.

About JPG, PDF, PSD and PNG formats

JPG, PNG, PSD and PDF files are bitmap formats that cannot be sized up without quality loss. We do not recommend increasing the pixel size of these formats.

About Printing and DPI

It is important to understand that dpi (dots per inch) is only a setting in the image file that tells the printer how to print the image - at higher or lower resolution.

More pixels = better printing resolution basically. Smaller pixel size images are not meant for printing unless you are printing at very small sizes because there is not enough pixel data for a good crisp printed image. The same image will look crisp on a web site because web site resolution is much much lower than what you need for most print

About Billboards and Large Format Printing

If the viewer is at a distance: You can print as low as 5 dpi for billboards that are to be seen at a distance to achieve sizes up to 11.48 feet x 15.00 feet with this image.

About EPS, PDF and AI formats

EPS, PDF and AI formats are scalable vector formats. Since they do not rely on pixels, you can resize them to be as large or small as you like basically without quality loss. You do this when opening the file in your graphics program. They are generally pixel independent.

If you are using these for printing purposes you generally should download the EPS or AI format and use a graphics program to open them in any size you like.

NOTE: In order to EDIT and make changes to the vectors in these files you will need Adobe Illustrator or another good vector editor.
