Method and apparatus are related to ink jet printing print resolution desired by this substrate absolute atmosphere. A kind of substrate promotes the first print head and the second print head below absolute atmosphere initial velocity, so that required print resolution is more than the first print head and the second print head of maximum printing resolution ratio. Substrate absolute atmosphere just roasting frequency is promoted on the first print head ejects ink when substrate advance First Speed operates, and frequency is baked to create the substrate strict atmospheric ballast that jet ink is advanced on the first Printing Zone and the second print head, to create the second print area. Successively, the region of the first and second area common definition print zones printing has desired print resolution.
