There can be different dash pattern was set up by the popup when you select an object dash pattern, which is a bug in the program.In this program, the "pattern" because they only remember the sequence numbers are shown below the text field, type the name or the line is not what it remembers.
I just can not interfere in the special.
When line width is generally smaller than 0.5, the dashed line pattern may not be as intended by the specifications of the printer.Also offset, PS printer specifications, screen and offset printing may be different.
Since by design of the printer, there is no way a solution.
