Here’s a tip for the beginners or those who don’t have much experience handling images for print. Resolution of images counts. While our premedia department can do some amazing things with our imaging software, they can’t do much to rescue a low resolution image. To successfully print a clear image, the rule of thumb is that you should begin with a resolution of at least 300 ppi (pixels per inch).
This means that if you are scanning an image, you should always scan images in at a resolution of 300 ppi or higher. If you are using a digital camera, keep in mind that the higher mega pixel camera you have taking the picture, the higher resolution the photos will be. Most cameras that can take photos above 3 mega pixels should be more than adequate to provide you with high resolution images. Keep in mind that you must have your camera set to the highest resolution when capturing your images.
You may think that you can simply resize a low resolution image to meet the specifications of 300 ppi, but all this really does is stretch the image. The only way to ensure picture perfection and high quality printing of your images is to start with a high resolution image obtainable by the methods we mentioned above.
