Info UV filter 420nm and 460nm EZMQC sw - CQXE Follow
Question: My customer has an old ColorQuest XE with the optional 420nm and 460nm UV filters. They were using Universal 4.10 and recently upgraded to EasyMatch QC. They now get different b* values and noticed that when they insert the UV filter they cut-off point is different. How can they get the cut off point in EasyMatch QC to match the cut-off point in Universal?
They can't. Universal and EasyMatch QC report differently when the UVF mode to insert the 420nm and 460nm UV filter is used. There is no reason to make changes at this time since Universal has been obsolete since 2008 and the ColorQuest XE is also obsolete (since 2017) and will soon be out of Service Support. You can request a software CMR but I would imagine it would be expensive since the customer would have to pay for the full cost of the modification since the instrument involved is no longer manufactured.
Below is information on how the different software reports when the 420nm UV filter is inserted.
Universal 4.10 with ColorQuest XE ; Report 400nm = 0 ; report measured values from 410nm to 700nm
EasyMatch QC v4.86 and lower with ColorQuest XE Report 400nm + 410nm = 0 report measured values from 420nm to 700nm with USVIS Report 400nm + 410nm + 420nm = 0 report measured values from 430nm to 780nm
EasyMatch QC v4.87 and higher with ColorQuest XE Report 400nm + 410nm = 0 report measured values from 420nm to 700nm with UltraScan VIS Report the same as ColorQuest XE, 400nm + 410nm= 0, report measured values from 420 to 780nm
