colour printing - further

• Autocad  has  a colour pallette  of  256 basic colours. However the darker shades of these colours look almost same or nearly black on screen. If u are using any of the darker shades, use a greater lineweight so as to make those lines properly visible.
• Light colours  like yellow or cyan  when printed on white paper, do not appear clearly.  Avoid them or at least use higher lineweight for them. Other way out is instead of pure yellow use a darker shade of yellow ( say colour no 40 ) so as to make it visible on a white paper.
• If u are using true colours, then remember that they will print in colour even after keeping the setting as monochrome CTB.  To ensure everything is printed in Black ( as required for a Tracing Paper print ) , go to the printer setting / options and choose " print in Black only " or "print  in Grayscale " .
