Optimizing image resolution
Back to the studio
Photos or graphics in PNG, JPG, GIF or BMP formats consist of pixels (picture elements) arranged in grid form, each of which is assigned multiple color information. The number of pixels in width and height also later determines the size of the print.
We print textiles at 200 dpi. The abbreviation dpi stands for dots per inch, and this provides information on the density of the picture elements. A graphic that is 1000 pixels wide, for example, produces a design 5'' wide when printed at 200 dpi. A 2000 pixel-wide graphic produces a 10'' wide design, etc.
A design with a low pixel width or height (for example, 800 x 600 pixels) cannot therefore be easily enlarged without loss of quality (for example to 4.7" x 4" or more). Because of the "missing" pixels, the print would probably look blurry and out of focus. So only upload designs with sufficient resolution and number of pixels. We recommend 200 dpi and a maximum of 4000 x 4000 pixels, so as not to exceed the maximum file size of 10 MB.
