Your original post contains two questions, each illustrated with a screen shot of parts of the CorelDRAW interface.
Your first question asks which of the built-in line styles is most suitable for microcapsule paper and/or embossed tactile graphics. In the case of both microcapsule and embossed TGs, line styles with more space between dots or dashes is preferable. Experience shows that the preset CorelDRAW line styles don't work very well for TGs because the dashes and spaces are not large enough.
Your second question focused on the "Edit Line Style" dialog in CorelDRAW and how it can be used to create your own line style. As displayed in the screen-shot you included in your original question, it is possible to use your mouse to create a custom line by clicking the little boxes in the "Adjust" part of the dialog to create a custom length dash or dashes. When a box/dot in the "Adjust" setting is black, it will be printed. When a box/dot is white, it will be part of the blank space between dashes.
The "Preview" portion of the "Edit Line Style" dialog box shows what your line style will look like. The "Preview" changes dynamically as you click on the "Adjust" portion of the dialog box so you can safely experiment with a line style before actually inserting it into a drawing.
Keeping all of this in mind, it is always important to retain dot and/or dash size, and spacing between dots and/or dashes, so that a tactile reader can distinguish different line patterns. Appendix F of GSTM contains a set of line styles showing how line widths, dash lengths, and spacing can be varied.

We hope this answers your questions!
