small amount of fixer to be removed, fresh water needs to be introduced into the wash section at the low rate of
a half-gallon per minute, thus saving water and energy. The high pressure of the water coming out of the
fountain jets is supplied by a pump and does not depend on having a high water pressure at the tap.
Dryer: As the print leaves the wash chamber, it passess through two transport rollers which also act as
squeegee rollers, removing any surface water.
a. The print then enters a clear-water rinse. It is submerged in clear water so that both surfaces get a
fresh-water rinse before going to the drying section.
b. Water from the tap enters this rinse chamber first, and as it leaves the rinse tray, it overflows into
the wash sump for use in the pressure wash. This double use of the water helps account for the low rate of
water consumption by the Royalprint Processor. The countercurrent arrangement, often used in conventional
washers set up in stages, provides the freshest water at the last wash stage.
c. As the paper leaves the wash section on its way into the drying section of the processor, it is
squeegeed twice by transport rollers and little surface water is left. In the drying section, air at 68 to 71C (155
to 160F) is applied to the prints. Because of the water-resistant paper base, only the slight amount of surface
water and the water in the emulsion have to be removed. Drying takes place in less than 15 seconds, and the
completely dry prints emerge from the processor less than a minute from their entry into the processor.
How many steps are there in conventional processing?
What does the term developer-incorporated paper mean?
What step in the conventional process is considerably shortened when using resin-coated paper?
The Kokak Royalprint Processor uses the
process which makes use
of conventional and stabilization processing along with water-resistant and developer-incorporated paper.
