Abstract

PURPOSE: To make it possible to shorten the suction time and obtain a satisfactory contact effect, by making flexible the upper light permeable material of the vacuum chamber, and newly providing the separate vacuum chambers at the upper and lower parts of the vacuum chamber.
CONSTITUTION: The first vacuum chamber 8 is formed by use of the flexible light permeable material 9 such as a transparent film, etc. and the photosensitive material supporting plate 10 such as rubber, etc. The second vacuum chamber 11 and the third vacuum chamber 12 are formed between the supporting plate 10 and the wall member 13, and between the light permeable material 9 and the cover member 14, respectively. Each chamber is equipped with the vacuum suction ports 18W20. This constitution is made its original state by removing the cover member 14 and the light permeable material 9, and inserting a negative 6 and a photosensitive material 5. Subsequently, after pressure has been reduced from each chamber at the same time, the vacuum of the chambers 11, 12 is released gradually, and printing is performed by making the negative 6 contact with the photosensitive material 5. In this way, since residual air scarcely exists in the inside, it is possible to shorten the suction time and execute the satisfactory contact.
