Recently, it is increasing to make use of an image printing system for the actual sized image with high resolution. Traditional printing systems can not print with one pass for a higher resolution image than that of printer's nozzle resolution. To resolve this, a multi pass printing algorithm, called as an interrace system, is required to compensate for printing errors and to achieve the resolution what we want. However, a high speed and resolution print bring about the degradation of printing quality with the ink cohesion between the closed ink injections. This dissertation presents a design method for an effective printing system of actual sized image, and then provides an implementation of the system along with its printing quality evaluation. It deals firstly with the degradation issue of printing quality with image transformation and enlargement, and processing speed with huge data requirement for the actual sized high resolution printing image. To resolve this, we design and implement the Raster Image Process(RIP) program which is appropriate to high resolution as well as high speed processing. Then, this dissertation tries to solve the degradation of printing quality issue of multi-pass printing due to the ink cohesion between the closed ink injections. To improve the printing quality, our approach makes use of a novel method to inject the ink with bi-partitioned pattern. The proposed methods has been implemented based on a simulation, and shown their superiority by a set of printing results. The proposed schemes are going to be conducted a real practice by applying them into an actual sized image printer. With some degree of refinements, we expect that our method provides an implementation basement of high resolution based actual image printer.
