They are ArgyllCMS supported instruments, so certainly not off topic! The two I have both appear to have no UV filter, although the nature of the DTP20's illuminant means that it seems to trigger the FWA a little less than the incandescent based instruments. I can find no mention of a UV filter in the DTP22-digital swatchbook documentation, but the DTP20-Pulse doco. does say that it has this as a factory fitted option. Graeme Gill.
