Master film for risographs is available in rolls of different widths and lengths, depending on the format, so the width of the master film for A4 printing is 210 mm, and for A3 printing - 297 mm, the length of the film determines the number of so-called frames (standard stencils) ), the length of the film varies between 200-220 frames (it is clear that the A3 film will be longer than the A4 film). Therefore, the cost of one frame of film will be equal to the price of a roll divided by the number of frames in it, for example, at the price of RISO Master A3 S-8131  , the cost of one A3 frame will be about $ 0.3, and the cost of A4 frame A4 A4 S-8188  for risograph SF5030, with a roll price of about $ 0.28, but if it is possible to place two A4 layouts in A3 format for output to RISO Master A3 ( S-6872 ),

However, the cost of making a master for printing one print in circulation directly depends on the circulation itself - when printing a print run of 10 copies, the cost of a master for one print will be $ 0.03, and when printing 1000 prints - $ 0.0003.

The master film, in addition to length and width, has another characteristic that limits the minimum cost of the frame - circulation (the number of possible prints from one master without loss of quality). Declared RISO circulation resistance for RISO film ( S-8131 ) - 10000 prints on risographs SF9350 and SF5350 , but for CV A4 TYPE 10 ( S-7041UA ) for risograph CV 3030 - 7000, in other words, the minimum price of the film in the cost of the print A4 format can be 000015 $ RISO Master A3 (S-8131e) and 0.00007 - for SF RZ A4 ( S-8188 ).

The cost of the frame is also affected by the quality of the master film, so RISO Maste Type HD S-6872  is more expensive than RISO Master SF A3 ( S-8131 ), but allows printing with a resolution of 600x600 dpi (for HI-END class - RISO SF9390 , RISO MF9350 .

In risography, in contrast to traditional screen printing, there is one significant drawback - the inability to use the printing form (master) repeatedly.
