Hi, i have just managed to lay my hands on one of these for a good price, I know it is an old model, but is supported by the Professional Edition and can’t be spending the big buck on a spectrophotometer at the moment.
I use Macs and from what I can find the software support has ended for recent versions of OSX, ColorPort 205 being the latest.
I have a DTP 70 that I acquired recently. It works well with Colorport and has never asked for a calibration strip.I am using Yosemite. It does exhibit some strange behaviours with colour targets. I would suggest scrambling patches and using a 9.5 to 10 mm patch size. I still have an I1P2 and io so can’t really comment on using it for 21x4 targets.
Ok got this connected on my workstation, printed the Piezography-21step-DTP70.tif on epson enhanced matte using the Hahn Photo Rag curve (recommend) and got a reading
Take i will have to buy the pro package/subscription to be able to do any profiling with it?
The droplets still work on DTP output so you don’t really need to buy anything else. I would use a 21x4 rather than a single 21 step. It’s easy enough to do with Colorport.
One other thing that you need to know about the DTP 70 is that the lever that switches the UV filter in and out is very fragile. I managed to break mind, and you can’t fix it.
Hi Walker. I have been using my DTP-70 and am having some success with generating profiles with ArgyllCMS. However, I have gained access to an i1Pro Photo V2 and consequently have access to I1Profiler. Your elegantly simple advice to use “DTP=70 and ColorPort for reading. Then just use i1Profiler to build the ICCs.” is eluding me. Colorport has a lot of options for saving data. Grateful if you could recommend one. And it isn’t clear to me how to use the ColorPort output file with i1Profiler. Some suggestions would be gratefully received. Cheers. Rob
Hi, so far i have only tried the trial version, i profiled 3 papers for a 7800 that i had brought back to life after purchasing it with some non printing channels.
Colour much better after the profiling, and process was easy enough.
When i asked if dtp70 was supported on droprgb this was the answer I got:
yes, you can drag any measurement file which contains RGB and XYZ or Lab or spectral data onto basICColor dropRGB an create an RGB ICC output profile.
Important: the text file must be a CGATS file!
I used adobe print utility to print profile and colour port to read and export to cgats file, just drop the cgats file onto droprgb, wait for it to do its thing, save.
I am using spyder5elite for screen calibration and am going to see if this software can be upgraded to spyderprint to create printer profiles.
Spyderprint can purchased for a little less than droprgb
