Fields Of Application
PFN-01T Technical negative photoplates are designed for portrait, landscape, architectural, subject and other technical surveys black-and-white photography.
PFP-01T Positive photoplates are designed for manufacturing of thermometrical scales, stained-glass windows and making of black-and-white images, which are examined in passing light or projected on the screen. There are three grades according to contrast: contrast, special contrast, and supercontrast.
PFRP-01T Reproductive semi-tone technical photoplates are designed for reproduction semi-tone black-and-white and color originals, which are notable for smooth (gradual) transition from shadow to light. There are two grades: normal and contrast.
PFRSh-01T Reproductive line technical photoplates are designed for reproduction of
highcontrast text originals and illustration materials in the form of strokes, specks and dots.

Main Sizes Of The Photographic Plates (In Mm) As Follows:
90х120, 90х240, 130х180, 180х240 per 6 plates (on glass base of 1,7-1,9mm thickness) in a cardboard box. According to an agreement between a customer and a manufacturer the photographic plates can be manufactured of other sizes.
Open and process the photographic plates under indirect safe light conditions with using a dark-red light-filter № 107.
Climate conditions for photographic plates usage: temperature of environment is (20 ± 5)оС, relative humidity of air (65 ± 15)оС.
Chemical-Photographic Processing Conditions Of The Photographic Plates:
|Name of operation||Time of processing, min||Temperature, оС|
|20,0 ± 0,5|
|Intermediate washing||0,1-0,2||18 ± 2|
|Fixing||10-15||20,0 ± 0,5|
|Washing||5-10||18 ± 2|
|Drying in the open air||To be dried out completely.||20 ± 5|
For photo-chemical processing of the Photographic plates Micron production plant manufactures sets of chemical agents for ST-1, UP-2M developers and BKF fixer for 1 liter; liquid concentrated solution of KF-PHOTO fixer.
Guaranteed Shelf Life Of Photographic Plates Is:
PFN-01T, PFRP-01T — 12 months
PFRSh-01T — 18 months
PFP-01T — 24 months
