검(Gum)프린트 제작용 네거티브 필름 적합성 연구

Abstract

acquisition of high-resolution when printing a photograph. However, the silver- halide lms may not be produced in the future. Without a silver-halide lm, it is di cult to enjoy classic printing, and making negative lms using an inkjet and laser printer is the reality before us. In this vein, this research was initiated as I thought that OHP Film, which can be acquired easily, may be able to substitute silver-halide process lms. When making a negative film in film printing centers, halftone screen lines are used, which can be done by using Photoshop. Therefore, in this research, I suggest how to create halftone negative by making negative lms in three pieces of OHP lms using an inkjet printer and a laser printer. As a result, due to the resolution of the printer, the halftone dot had the identical size and density of the process lm printed in the center. However, the shape was not elaborate enough. In the experiment, the di erence in the thickness and transparency of the lm expanded the exposure, which did not have a signi cant impact. As a result of the output, the negative film made by the inkjet printer was similar in the highlight section and the middle section, but the gradation in the dark section was somewhat weaker. On the contrary, the output of the negative lm made by the laser printer was weak in all sections. In conclusion, although the negative lms made by applying the halftone screen lines to three pieces of lms had low resolution, they had a sense of their own. Photographers and researchers wishing to learn classical printing may be able to use this in lieu of silver-halide process films when they intend to create lms for printing based on digital media. However, in gum printing that requires elaborate description of details, the low resolution of generally-used inkjet and laser printers may become the limitations.
