3 Map specifications

3.5 Printing– Controller must check the quality of the printed map

Controllers Workshop - The orienteering course map


3.5 Printing– Guidelines for WRE’s• Traditional spot colour, offset printing is best practice

‒ WRE’s permit non-offset printed maps if:• the quality is very good• overprinting effect of spot colour printing is simulated• paper is suitable• compares favourably with the PrintTech test sheet (spot colour,

offset)• approved by MC (3 months prior to event)



3.5 Printing‒ WRE’s map approval process for non spot colour, off set• Event Advisor to check quality• If OK 3 course maps and 3 ‘test sheets’ sent to MC • MC will either:

approve suggest how to make improvements reject



3.5 Printing– Aust Digital Printing Policy 2.10

• For the Australian Long Distance Championships, where the map is particularly detailed, the scale for 16 - 40 year age classes may be 1:10000 with approval of the OA Director, Technical (OA Rule 15.3).

map must still be legible at 1:15000 with spot colour, offset printing

• For Group A Events, map deviations need the approval of the OA Mapping Officer (OA Rule 15.1)

3 months notice required

map samples or ‘PrintTech’ test sheet should be provided re suitability of the printing method

digital printing is OK if there is no significant loss of line quality, legibility, colour appearance and map durability (OA Digital Printing Policy)


3 Map specifications3.5 Printing

– Printers (14th ICOM, Trondheim, Norway, 2010)

• 5 or 6 colour spot colour, off-set using Pantone (PMS) colours is best practice

• 7 colour off-set (CMYK + brown + green + purple) is very good for large print runs

• 7 colour digital offset (CMYK + orange + violet + turquoise), wet toner transfer, is good for low print numbers

• 6 colour off-set (CMYK + brown + brown + purple) is good • 5 colour off-set (CMYK + purple) is not suitable• 4 colour laser (dry toner transfer) is not suitable at all

– Reality• 4 colour CMYK laser printers used widely in Aust • Spot colour, off-set maps printed for elites at Aust Champs, but not

always• Switzerland has printed CMYK, off-set since about 2005. Includes World

Cup and other WRE’s



– Printers (14th ICOM, Trondheim, Norway, 2010)



– Use the IOF Map Commission Print Tech Project ‘test sheet’ to:

• Check print quality• Check colours

– Spot colour, offset sheets available– Check for:

Sharp edges, no zig zagEven coloursNo stripesNo moire effectVertical & horizontal accuracyDo contour lines have the same appearance over the colour screens ie often a problem over mid & dark green



– Use colour blocks on the map to check against the PrintTech colour sheet



– Check the colour Purple

CMYK 43 91 00 00

CMYK 30 100 15 00 Recommended



3.5 Printing– Example: Controller to check print quality and colours of the course map



3.5 Printing– Example: Use the same print setting for all course maps



– Paper quality• bright white paper (not off-white) for best colour contrast• matt finish (not glossy or shiny)• paper weight: 80 – 120g/m2• durability of paper in all conditions• need for a plastic bag, thickness: 0.10mm• texture and folding ability• suitable papers: G-print 80-120gsm, Impress DM Matt 100gsm,

Colour Copy 100gsm• suitable waterproof paper: Teslin150 gsm, Pretex150 gsm

– Map size• should not be larger than is necessary• recommended sizes are A4 and A3


4 Explanation of symbols

4.1 Land Form

4.2 Rocks & Boulders

4.3 Water & Marsh

4.4 Vegetation

- Controller to check Runnability ie running speed through the forest

• open forest 80-100% white

• slow running 60-80% light green

• difficult to run 20-60% mid green

• very difficult to run 0-20% dark green

nb Sprint maps have 4 Greens (very dark green / not to be crossed)

4.5 Man-made features

- Special man-made features to be defined in the map legend

ie Special man-made feature – car wreck



4.6 Technical symbols– Magnetic declination

Check on site with compass

Check geomagnetic data at Geoscience Australia

– Spacing of N lines150m 1:5000/4000

250m 1:10000

500m 1:15000

20 - 40mm on map

– Breaks in N lines



4.7 Overprinting symbols– Overprint effect of spot colour printing is required for WRE’s

No overprint effect Overprint effect & transparency



4.7 Overprinting symbols– For multi-age competitions in which both 1:10000 & 1:15000 maps are used, the

size of the symbols on the 1:10000 may be 150% larger than on the 1:15000 maps


5 Field Checking

5.1 Using GPS for controlling– OCAD can create files for exporting to Google Earth and handheld GPS


5 Field checking

5.2 Using GPS for controlling– GPS can help check map accuracy– GPS can verify position of control placement when in the field


6 Check list for controlling the map making process (as per IOF)

6.1 Visits to the terrain & meetings– 1st visit: before any mappingsuitability of the terrain, any deviations required (seek approval as necessary)

getting to know the personnel, timelines, suitability of base maps

– 2nd visit: after some mappingcheck sample maps of all terrain typescheck level of generalisation, map legibility, runnability, etc

– 3rd visit: mapping complete but subject to correctionscheck for corrections, quality of mappingmap layout & design, credits, logos, special symbols defined

6.2 Controlling during competitionno mistakes at map printingno mistakes in control descriptionswhere will the maps be kept (before and at the event), spares, set of maps for search & rescue, etc


7 Map deviations7.1 Some recent Australian map deviations

– Using two symbol sizes for Termite mounds– Using ISOM fence symbols with Sprint maps (Sprint only permits 2)– Sprint scale of 1:3000– 1:10000 scale maps with 1:15000 scale symbol size– Vegetation areas under size – Cliff lengths too short– Special man made feature not defined– Using non standard symbol

7.2 Approved map deviations

– ISOM symbol 209 Boulder cluster approved for Sprint map as no equivalent symbol for ISSOM (2011 Sprint prologue, WA)


8 Other considerations

• Controller and Course setter should use the same software– Map: OCAD– Course: OCAD, Condes, Corpse, Purple Pen– Have a system to track updates, corrections & map changes

• Ensure sufficient space between the map edge and controls or likely route choices

• Avoid covering part or all of the legend with the control description

• The sides of the map should be parallel to the magnetic north lines

• Map credits


8 Other considerations

• Relays– OCAD can handle simple to complex leg variations– Team combinations generated automatically by OCAD – Team combinations exported to OS


Example: Complex splitting• major forking within courses• 27 different maps• 72 combinations

printed at 1:7500 for non-elites? Identify issues and give reasons for your decision. Fact: symbols are undersize by 4-13% to ISOM2000


10 Tasks

10.2 What is your decision as controller– Q1 Should a Sprint map be used for a Middle Distance event?– Q2 On the Sprint map below are competitors of a Middle Distance event

permitted to cross the Impassable wall between leg 19 to 20?
