PREPARING FILES FOR PRINTING

 

 

 

RESOLUTION

Resolution refers to the number of dots per square inch or DPI. For quality printing, 300 dpi is required. The more dots, the more detail, but creating a file more that 300 DPI will not improve quality and it will only make files size too large. Creating files at higher than 300 DPI adds unnecessary information and waste time processing.

Less dots, less sharpness and detail. Never send a file from something you have taken off the internet. If the original file size was online, it is 72 dpi and you cannot add more information to expanded it to 300.

Make sure all your images are 300 dpi or higher in order to produce best detail. Anything less will result in poor quality.

Although 72 dpi looks acceptable on your monitor, 72 dpi will result in poor image quality on printed products.

 

 

 

 

CHANGING RESOLUTION

 

If file is not at 300 dpi, you can not just increase resolution to higher one. The printed result will be blurry image.

 

INSTRUCTIONS FOR CONVERTING IMAGES TO 300 DPI IN PHOTOSHOP

Go to Image Size. You do not want to change pixel width or height. These dimensions will stay the same. Make sure that "Resample Image" box is not checked. This will make sure that pixel dimensions does not change. You must then change the resolution field from the 72 pixels/inch to 300 pixels/inch.

 

PLEASE NOTE: Size of Document Image will change.
If the size you end up with is too small for what is required for your file, it is best to use another image that can be printed at 300 dpi.

 

This image will now print much smaller than it would at a resolution of 72 pixels/inch, but what is lost in physical size, is changed for image quality. At 300 pixels/inch , a sharp, detailed, print quality image results.
