Hi there, I am new to the mailing list. I noticed a recent message in the archives from Graeme Gill mentioning that he has been able to get the DTP-22 digital swatchbook spectrophotometer device working directly with Argyll but possibly with a caveat concerning the use of an internal switch. I am thinking of buying this device so I am curious to know exactly what the problem with the switch is and whether it will in fact be possible to use this device directly with Argyll CMS. Elsewhere on the web people have mentioned that a password may have to be sent to the DTP-22 before it will respond with the spectral data. Is this a problem and should I check whether the DTP-22 device has such a password before buying it? Presumably without knowing the password it would not be possible to use the device. I intend to use the device, possibly with Argyll CMS, to produce profiles for my inkjet printers (Epson and HP models). I did have a quick look a the Argyll CMS source code, but could find no mention of the DTP-22. Perhaps this feature is too new to be in the release version. Any pointers will be greatly appreciated, and I hope this is not too off-topic for the list. Regards, -- Mario Becroft <list@xxxxxxxxxxxxx>
