Printing Orienteering Maps
Offset, spot colour printing is recommended for all World Ranking Events.
Guidelines for printing non-offset, spot colour maps for World Ranking Events is availabe here .
Testing the suitability of non off-set / spot colour print machines for printing high quality orienteering maps is a continuing process. A Print Tech ‘test’ sheet print from a printer in South Australia in May 2015 indicates the map printing depending to some extent on the terrain, should be suitable for WRE’s for the map scale of 1:15000. Advice on using non offset, spot colour printers and achieving the simulated Overprint effect may be obtained from the OA Mapping Committee Chairperson. Also see below in this section the Guidelines for printing non offset spot colour maps.
For use in Australia, a summary sheet “Map Scale and Printing Method Decision Process” is designed to assist controllers, organisers and course planners when to use spot colour, offset printing or digital printing and what scale to use for an event.
Quality control for non offset, spot colour printed maps
In 2002 the IOF Map Commission began a project to gather the latest knowledge about non-offset printing. Results from this project are available at the Print Tech Project Site
A key output of the project is a ‘test sheet’ that can be printed from a digital printer for comparison to a spot colour, off set printed version of the same file. Digital copies of the ‘test sheet’ in both OCAD and PDF file format and instructions on using the test sheet may be downloaded from the Print Tech Project Site.
The ‘test sheet’ is recommended as a quality control tool for assessing the suitability of a particular printer in respect to print quality and colour reproduction for orienteering maps.
Copies of the Print Tech spot colour, off-set printed ‘test sheet’ are available from the OA Mapping Committee Chairperson.
When digitally printing maps it is critical that map colours match as much as is possible the colours of the spot colour, off-set printed Print Tech ‘test sheet’.
When comparing map colours it is useful to print colour blocks at one side of the map as per example, and then compare directly to the colour blocks of the ‘test sheet’.
In the same way as above the course marking colour can also be printed as a block colour at the side of the map. The recommended setting for the colour Purple is 30%Cyan, 100%Magenta, 15%Yellow and 0%Black. In OCAD the default colour setting for Purple of 100% Magenta is unsuitable particularly for colour blind orienteers.
As colour output varies from printer to printer, particularly from inkjet printers to laser printers, colour settings may need to be varied for each printer so as to achieve the best result. In all cases it is necessary to do trial print runs of the course map and check colours against the ‘test sheet’, and make adjustments as appropriate. If using an off-white waterproof paper it may be necessary to increase colour strength to ensure good differentiation of map colours.
To assist in the process of matching colour out put to the official colours the following colour swatch charts in OCAD9 format may assist:
Guidelines for printing non offset, spot colour maps
Guidelines on digital printing may be found at the Mapsport web page. As at April 2012 the following papers were available:
G-Print paper is recommended by the IOF PrintTech project although in Australia this paper is not available but replaced with Impress DM Matt, 100gsm.
Good quality white copy paper with a weight of 80-120 gsm is recommended for all orienteering maps ie Colotech+ iGen3, DocuColor, colour laser and colour copier, 100g/m2
A paper weight of 100 gsm is recommended when used with a plastic bag thickness of 0.10 mm.
Waterproof papers tested as suitable for orienteering maps in Australia include:
- Pretex: 50.120 (120 gsm)
- Durapaper 203micron (Teslin)

In some cases the control number may be difficult to read particularly where the number is placed over complex areas or solid colour areas. To improve legibility a 0.10 mm – 0.20 mm white boundary may be added to the number. The OA Map Committee has considered (4/08) that this may be used for Sprint maps.
Map Subsets, Legend and Map Boundaries
Good practice dictates that all maps should have a legend, and further no part of the legend should be covered by the control description. Where this is not possible due to insufficient space on the map subset, then as a minimum requirement, a separate legend sheet using the same printer as used for the map should be printed and displayed for all participants.
When selecting a map subset, the map edges should where possible follow easily identified boundaries ie fence lines, roads, major water features, cleared farmland; thereby reducing the likelihood of the orienteer running off the map. This may require consultation with the planner to ensure that there is sufficient space between the edges of the map and any controls or likely route choices.
Logos for major Australian events
The logo for the IOF, Silva National Orienteering League, Orienteering Australia and the Australian Sports Commission are availabe in OCAD 9 format below. The logos may be used on Australian orienteering maps as required.
(1) Non offset printed maps (CMYK)
(2) Spot colour, offset printed maps
For spot colour, offset printing the colours in the logos may need to be changed to the available spot colours used for orienteering maps (6 spot colours excluding overprinting). The OCAD 9 version below has the logos changed where necessary to the available spot colours:
