What causes pixelation?
Pixelation is caused by a digital image being too small to be printed smoothly. Printers print out each pixel as a small blocks of color, the smaller the blocks, the less our eyes notice them. A lot of magazines print out at resolutions of around 300 DPI, meaning that a 300 pixel by 300 pixel image would be printed out as a 1 inch square. This is generally a good resolution for quality. If the same picture was printed at 2″ by 2″, your printer would simply use larger blocks of colour. When these blocks become noticable to the eye, the output image is pixelated. Of course, if you enlarged the image using Enlarger PRO before sending it to the printer, it would still look like the original.
