An aspect of the present disclosure provides a method (400) of reproducing a page description language (PDL) page (103) using an output device (104). The method (400) comprises receiving a PDL page (103) comprising a graphical object (302), the graphical 5 object (302) being associated with a first conversion factor relating a physical space to a user space of the PDL page (103). The method then determines (401) a scaling factor for the graphical object (302) based on a transformation matrix for converting the user space to an output device space of the output device (104), a user space unit of the user space, and an output device space unit of the output space. An adjustment value based on a function of the 10 first conversion factor and the scaling factor is then determined (404). The transformation matrix for the graphical object (302) is modified (405) based on the adjustment value and the modified transformation matrix is applied (406) to the graphical object (302) when reproducing the graphical object (302) on an output medium (105) of the output device (104).
