RH Designs Analyser Pro Calibration of Kentmere VC Select Paper

Kentmere VC Select

I've been spending some time experimenting and printing with the latest version of the Harman produced Kentmere VC Select RC paper which appears to have been slightly reformulated compared to the original Kentmere factory made versions (pre-2008). In a effort to get repeatable results from my RH Designs Analyser Pro (also applies to Zone Master II) as well, I've come up with some calibration settings through trial and error and a fair bit of paper usage. Both of these exposure metering devices are configured to using the standard 1/12 F-Stop mode setting. My tests have been by actual printing and not by any technical method of using a density measurement device, only by visual inspection of dried down made prints comparing VC Select to the same negative printed on Multigrade IV RC Pearl within 10 mins of each other. Grade for grade the Kentmere is about half to three-quarter of a grade higher in contrast compared to Multigrade IV and is about 75-100% faster ISO rated paper speed.  I used a LPL7700MX enlarger with Kodak Y/M filter chart. All half grades paper settings are automatically calculated for you by the device.

Grade    Filter

0        90Y/0M
1        68Y/10M
2        41Y/32.5M
3        23Y/57.5M
4        6Y/102M
5        0Y/199M min/max range

On the whole I'm very pleased with these settings, very clean whites and strong blacks but not over-powering. Somehow my Ilford Multigrade IV prints look quite flat and boring now. The new kentmere is much more snappier and puncher plus has a whiter and slightly thicker paper base.
