To get a perfect printout with FotoPrisa Printer, first, there are 3 points needed to really take care of for choosing an appropriate image input:

Image size

Before we go into the topic, there are several important terms to know in advance.

A digital image is composed of a minimum unit called pixel. With the variation of pixel properties, you can create various effects to the image. To measure the density of pixels (or resolution) in an image, we use dpi (dots per inch) to see how delicate the image will be to our eyes. If an image is composed of more pixels, it has larger image size. If the image has higher resolution, it will seem more delicate and details in the image can be presented more clearly.

FotoPrisa Printer is a 4" x 6" photo printer at a resolution of 300 x 300dpi or 300 x 600 dpi. Actually the maximum print area (full size) is about 4” x 5”, or 1200 pixels (=300dpi x 4”) x 1500 pixels (=300dpi x 5”). Therefore, in order to have a full-size, true-color printout, it’s better to find out an original image of which data size is bigger than the wanted maximum image size (resolution x print area, that is, larger than 1250 pixels x 1500 pixels). Thus we can fully utilize the advantage of the 300dpi resolution offered by the printer.

Of course, it's hard to always get an image bigger than what we need to print. Indeed that will not be a big matter if we got a somewhat smaller image size, the printout can be still vivid to our eyesight via FotoPrisa Printer. However, if the image size you choose is much smaller (under half of the wanted maximum image), either you sacrifice the resolution to have a more blur printout or you can only get a smaller size of printout without
