A second solution is to use Harald Laban s AB C+ Pyro (available as Photographers Formulary Rollo Pyro). Adherents to Rollo Pyro claim that because of the use of ascorbic acid (vitamin C) as a preservative and a large quantity of pyro, it does not oxidize like traditional pyro formulas and can safely be used with JOBO rotary processing. Compared to other pyro/ cat developers, Rollo Pyro creates a light image stain. [Pg.63]

Pyrocat-MC is a Pyrocat variant that I recommend primarily for rotary processing, where it tends to give slightly greater acutance than Pyrocat-HD. It can only be mixed with propylene glycol. [Pg.69]

This high acutance formula is especially suited for stand development and minimal agitation techniques, although normal intermittent agitation and rotary processing may be used. [Pg.221]

For rotary processing dilute 1 5 (200.0 ml of stock solution to 1.0 liter of water). [Pg.222]

Flexo printing is similar to the traditional rubber-stamp techniques that have been in use for hundreds of years. The primary difference is that the flexible stamp (chche) in a flexo process is wrapped around a drum to be used in a continuous rotary process. In order to control the reinking of the cliche, an anilox roller, a metal or ceramic roller with small indentations (wells) of uniform size and shape, transfers ink firom a fountain to the cliche, as shown in Figure 4.6 through Figure 4.8. Diflferent rollers can be purchased to control the amount of ink that is transferred to the cliche. A doctor blade removes excess ink firom the anilox roller before it contacts the cliche. [Pg.1228]

FIGURE 4.12 Rotoscreen printing schematic. Ink is pressed through a screen to the substrate in a continuous (roll-to-roll) rotary process. In this case, the substrate and screen move, and the spatula remains stationary. [Pg.1236]

Flexographic printing n. A rotary process employing flexible rubber or elastomeric printing plates adhered to a roll, inked by a screen roll which in turn is coated from a feed roll immersed in ink. [Pg.417]
