Office Digital Printer – OKI C321dn

Using Printech Project test 2006 sheet to test

OKI & Printech Project sheet

Having just posted some new print and colour guides in the Resources section of this website, I was most interested in a print quality test experience on Swiss O-map blog O-Zeugs.

The author (presumably M Lerjën – I’m writing this under the shade of our plum tree and the combination of light colour text and myriad screen reflections makes it hard to be sure), has just bought an OKI C321dn colour laser printer and is now checking it out as to map print quality. Interesting to buy first and test later but as highest quality wasn’t a primary motive to buy, then I can understand that process.

The blogger then put the OKI through its paces via the Printech Project test sheet. While his conclusion is that

with my OKI I will never reach the high end.

the process he goes through and the explanation of the results he gets is definitely worth a view by anyone faced with checking out a digital press for O maps. This applies whether it is an office press like this OKI or a commercial press.

That particular blog post is OKI C321dn and the Printech Project Test Sheet.

The  later print quality test blog post Mappers Blog: Color correction of the OKI c321dn for printing maps covers his attempts to colour match the OKI output to Swedish O colour specs. The result is the same as reported in my guides – yellow and pourple are very difficult to match.

Orienteering Australia has available a similar offset printed colour matching swatch. I included that with most Pretex despatches in December. They can also supply offset printed Printech Project test sheets for comparison testing.

Post script

Re “… his conclusion …” in the 3rd paragraph above. Often I would put his/her but it struck me just a couple of weeks ago that I don’t know of any female orienteering mappers. I’m sure they are out there.

Wouldn’t you know it. Just a few hours after writing the above, via O-Zeugs I read of a female mapper.
