Cyanotype print successfully with "virtual negative" (Duobond 6 inch 2k monochrome LCD) on photographic enlarger / no contact printing
Hybrid printing system:
A digital negative image appeared on a Duobond 6 inch 2k monochrome LCD (no backlight itself, originally used for a 3D printer), herein called "virtual negative", was successfully formed on cyanotype (or Van Dyke) photographic paper using an analog photographic enlarger (light source: 395 nm UV SMD). This virtual negative method differs in this respect from previous digital negatives on OHP film (contact printing) and analog negatives as attempted by group: www.flickr.com/groups/cyanotype_wenlarger/).
Image signal is output to the LCD via HDMI from a mini-PC (OS: Windows 10) with a built-in graphics board capable of up to 4K video output.
----
Printed on Cotman water colour B5 sized paper / exposed for 8hrs
Original picture: scanned from an abandoned 135 monochrome negative film taken in 1950s (Nagoya, Japan)
Sensitizer: Jacquard cyanotype kit (Potassium Ferricyanide & Ferric Ammonium Citrate)
Toning: none
Enlarger: LPL Model 7451 large format enlarger (EL Nikkor 150mm / F5.6)
Light source: High power (50w) UV LED unit (SMD=surface mounted LED modules)
The condenser unit (= a unit in which two 16cm diameter convex lenses are set facing each other) was removed from my old Hansa patent enlarger for use in LPL Model 7451.
