Which highlighters will show up when faxed or copied?

Sensitivity of copy and fax machine's can vary greatly. If you do not want the highlighter to reproduce a washed-out outline, we suggest setting your copier on the lightest setting and try a dye base highlighter, such as their tank style highlighter (formerly Major Accent) or Pocket Accent in yellow or light blue. If you want highlighted text to reproduce in Gray when copied or faxed, they suggest using the darker colours of a pigment-based highlighter, such as their Liquid Accent.
