We need your print data in JPG, PNG or TIF format.
The CMYK colour space is used for printing, the RGB colour space for display on screens. Accordingly, we need your print data in CMYK. If you provide us with RGB data, we will convert them into CMYK.
The resolution is given in the unit of measurement dpi (dots per inch). In principle, the higher the dpi number, the sharper the print result. Required resolution: 300 to 356 dpi.
