PROBLEM TO BE SOLVED: To obtain a laser exposure system in which the labor of a worker required for matching the scan start position and the dot pitch is lessened significantly. SOLUTION: The laser exposure system comprises a test exposing section 211 for forming R, G and B exposure lines corresponding to R, G and B laser beams on a photosensitive material 1 in parallel with the main scanning direction, a section 212 for acquiring various test exposure data, a first clock frequency calculating section 213 for setting the dot pitch of the R laser beam at 320 dpi based on the test exposure data thus acquired, a second clock frequency calculating section 214 for setting the dot pitch of the G and B laser beams at 320 dpi, and first and second sections 215 and 216 for matching the scan start positions of the R, G and B laser beams.
