Claim:
1. A printer for forming a phase change inkjet image on a print substrate, the printer comprising: a sheet transport unit configured to advance the print substrate along a print station, said sheet transport unit comprising a sheet support platen, a sheet attraction mechanism and a feed mechanism, the sheet support platen comprising a print surface for supporting a contact side of the print substrate, the sheet attraction mechanism being arranged for attracting the print substrate to the print surface and the feed mechanism being arranged for advancing the print substrate in a transport direction over the print surface, and said feed mechanism being arranged upstream of the print surface; and a print station comprising a print head assembly, the print head assembly being arranged for providing ink droplets for forming the phase change inkjet image on a process side of the print substrate when the print substrate is arranged on a print area of the print surface, the process side of the print substrate being opposite to the contact side, wherein the print surface has an average surface roughness Ra being in the range of 1 micron to 4 micron.
