Several years ago I produced a [free] B&W printer test image that I know has been widely used to get a feel for printer/paper/ink performance.
A while ago I asked for feedback about what aspects people found useful and what could be modified/improved (many thanks to all who commented)
After testing several new papers recently, I've been working on an updated test print image.
http://www.northlight-images.co.uk/article_pages/bw_printing/bw-test-image-2.htmlThis version is available at A4 size, 300ppi, and incorporates a 51 step ramp for linearity measurements (a 21 step version is also available) If popular, I could re-arrange the elements to fit on a letter size sheet (other ppi settings require rather more work)
There are lots of features in the image addressing different aspects of print quality, which I've covered in the article with the download links. The image contains the exact same photographic elements as the original, to maintain compatibility with any previous test prints.
I hope it's of use, and please do let me know (directly or here) if it's of help?
