Printing transparencies or hatching

PTMapper has the ability to display areas of the map filled with either hatching or transparent colours. Unfortunately printing these areas can sometimes produce less than ideal results. Often the transparency effects are replaced with a solid colour, or the hatching is too bold and the lines are too widely spaced.

PTMapper has no option to edit the hatching styles and you can only alter the percentage of transparency available.

So to produce the best results, you will need to delve into the Print Quality settings in your printer software. Each make of printer has its own printer software and almost all have settings that allow you to alter the print quality.


Select the printer that you will use and then select the Preferences button:

Printing preferences


You will then see the Printer Settings page for your printer. Find the section which covers the Print Quality settings. These come in two styles – a list of figures for DPI settings (dots per inch) or a list of predefined quality settings.


Below is an example of DPI settings:

Below is an example of predefined Print Quality settings:

If you have a choice of DPI settings available then a typical standard setting will usually be set to 300dpi, so try a higher setting. e.g. 600, 720, 1200dpi, etc. Although there may be higher options available (2400, 4800, etc) they are not recommended as they do not usually provide better quality, but will increase the amount of time to print and the quantity of ink used.

If you only have preset options then try higher settings e.g. High Quality, Best, etc. Some printer settings may include Custom as an option and this can then give you further options. e.g. CAD, Photo, Drawings, etc.

If your printed transparency settings are now looking reasonable then you can often improve the final results further by varying the percentage of transparency.


If you still can’t produce a suitable print then an alternative option is to produce the print as a PDF and then print the PDF instead.
