1 IOF Guidelines for using non-offset printed maps in WRE’s
1.1 Using the PrintTech test sheet to check for:
Colours to Pantone & test sheet
Even colours, no striping
Print quality ie sharpness to edges
Vertical & horizontal accuracy
Do contour lines have the same appearance over the colour screens ie often a problem over mid & dark green
No moire effect
Etc, as per instruction sheet available on OA web
Test print sheets available here
OCAD & PDF files available on OA web

2 Review & discussion of maps printed for recent carnivals
Australian Champs, Tanunda Creek, SA
What the MC said:
I am wondering if there is a problem with the paper, as the tiny font black text on the map is quite blurry (or are these scanned images?).
Font changed to graphic
Contours get fussy and appear a bit thin, partly due to a slight colour misalignment (black is a bit SW of magenta / yellow), but are readable in the white areas.
Printer issue
No overprint effect. This causes readability problems, in particular in the green areas (contours and blue features).To achieve overprinting effect when printing directly from OCAD, all one has to do is to use the spot colour view while printing (then only the spot colour colour definitions are used - the CMYK values in the big colour table are ignored).
Issues with overlapping areas, colours for logos and map colour settings

What the MC said:
Courses are not printed transparent (overprinted). They should be! This is also easily achievable using the draft mode when printing courses in OCAD.
Agree
Colours are not bad. Purple is good! The green is perhaps slightly too blueish. Have you checked how this combination of yellow colour and green colour is perceived by colour blinds?
I think OK!
High quality plastic bags!
Great

Frazzle Rock Easter carnival, WA
What the MC said:
Overall, the quality of the printing is good.
The resolution of the printer is quite good, and seems to be sufficient for 1:10000 maps.
The colours are also quite good, but to me, yellow seems to be a bit pale and with slightly too much magenta.
There is no overprint effect. With spot colour PDF, it should be possible to specify overprinting in the file.
But then you will have to inform the printer about the spot colours used. I know this was done for the WOC 2010 maps.

What the MC said:
The course overprinting is not transparent. With EPS, I guess you have to ask the printer to implement the overprinting effect in order to accomplish this. PDF is a possibility.
Have you done any investigations into FM (frequency modulated) raster / stochastic raster? It is used for CMYK offset printing of orienteering maps in Switzerland, and some advanced RIPs for laser printers support this.
The results are generally much better than regular rasters for orienteering maps.

3.3 PDF image format
Portable Document Format is now the industry’s standard file format
OCAD will export PDF as Vector or Raster
PDF Vector is essential for high quality map printing
Raster Vector

3.3 PDF image format
Vector images
have points connected with lines (straight or curved) and filled with a colour
are infinitely scaleable
CorelDRAW, Adobe Illustrator & OCAD are vector based programs
Raster images
Are made from thousands of dots (pixels)
CorelPAINT, AdobePhotoShop

3.3 PDF image format
Maps with out Background raster images will automatically be exported by OCAD as vector and create settings in the PDF file for best reproduction
Raster images (ie .jpg) used as a Background map will cause OCAD to automatically export the PDF file as a raster image. OCAD will also ask for a Raster resolution to be entered ie 300dpi
Raster images should be redrawn in OCAD or obtain the image in an OCAD importable file format such as ai,.pdf, .emf, .wmf, +

3.3 PDF image format
Do not use PDF raster files as the print quality is inferior to vector.
Also, high resolution raster files are very large in file size.

3.4 Overprint / transparency from CMYK digital printers
Printing from OCAD
Overprinting effect of the course achievable by
Course file: View > Draft: both sliders to the RHS
Transparency possible but proven to be unsatisfactory
Printing from PDF
CMYK offset digital printing requires the O(verprint) column in the colour table to be checked
Use Export PDF in OCAD to create PDF vector
Refer to Ken Dowling’s technical papers

3.5 Printing direct from OCAD
Printing from OCAD has two big advantages:
One file for all courses whereas PDF requires a separate file to be created for each course and;
relay course leg maps and team combinations are automatically handled by OCAD both at the printing stage and also for importing into OS (Sportident timing & management)
Only one known Print Shop in Australia currently prints from OCAD ie Snap Printing, Hilton, SA
Tasmania has own printer
