RH Designs Analyser & ZoneMaster Calibration of Silverprint VC RC Proof Paper
I purchased from Silverprint UK a couple of boxes of their own special brand of "Proof" Variable Contrast RC paper which has a dead matt-surface which is very unusual (glossy and semi-matt been the norm within the industry). This appears to have been a one-off special purchase arrangement with Harman Technology Ltd (product maker). The same people that make the world famous Ilford Multigrade IV darkroom paper. Been a unique printing paper, I needed to calibrate my RH Designs Analyser Pro & ZoneMaster II devices to accommodate aiding correct exposure timing and contrast settings. Therefore, I've come up with the following figures as a guide after some experimental testing which I wanted to share, should anyone else be using this setup in their workflow.
The testing was done with an LPL 7700mx colour enlarger set for using standard Kodak scale "Yellow & Magenta" enlarger filters as listed in the RH Designs product user manual or see this link: http://www.rhdesigns.co.uk/darkroom/html/filter_settings.html for different enlargers.
Now, let's get started.
Enter calibration mode on your metering device and enter a -12 (minus figure) for all grades 00 through to grade 5. That's about a 1x stop faster ISO paper speed than MG4 paper. When done, enter the contrast range as follows.
Grade 00 = 180 (one hundred and eighty)
Note, half grade steps are automatically calculated by the device and do work well. My figures will give you good starting point.
Please bear in mind that this paper has a totally dead matt surface hence blacks are a little bit weaker compared to Ilford MG4 satin finish, but can be compensated for by adjusting the contrast level figures to suit individual tastes.
Overall, I'm really pleased with this paper, so smooth almost book like. Even Ilford's own MG4 satin has a sheen/slight gloss to it in comparison. The chemistry used for all these prints was Ilford PQ Universal Print Developer, Fotospeed SB50 Stop Bath and Fotospeed FX30 Fixer.
Here are some examples of my darkroom prints made using this paper
Unfortunately, Silverprint UK have now sold out of this paper
