Anyone who is involved in printing or design needs to know certain things about resolution. This article will serve as a quick guide to the basic concepts of image resolution. In addition, I will show you how you can get a Vistaprint Coupons so that you can get great deals when you print products online.
Images are actually made up of many little dots, which are called pixels on the computer screen or dots on a printed image. The resolution of images are therefore measured in pixels per inch/ppi, or dots per inch/dpi . Higher quality images, naturally, will have to contain a greater number of dots or pixels per inch.
When you open a file that was meant to be viewed over the computer, chances are that the ppi will be set to 72. A higher resolution than 72 is not necessary for images on the computer. In fact, a higher resolution than 72 ppi does not look any better on the computer. But when dealing with printed images, things get a bit more complicated.
When preparing a file for printing, you will need to raise the resolution to the industry standard of 300 or higher dpi. At resolutions below this, a printed image will likely look unclear or grainy, and should not be used commercially.
It does not matter what the original dpi is, since you can raise this number in a graphics program like Photoshop. If you raise am image's resolution, however, the image will also grow smaller. When in doubt, purchase or use large images so you have room to play around.
For professional printing, I generally prefer to use Vistaprint Coupons, since I can get some great deals every time I use Vistaprint for my printing needs. I recommend using online printers because they cost less than other printers, and also do very good work. To get Vistaprint Coupons, I usually visit coupons sites or search for them on a search engine.
