DITTO - reproduction

from Fancyclopedia 2

A method of reproducing by dye-transfer process; like hektoing (and hekto carbons are used to make the master) but using a dye solvent instead of a gelatin transfer medium. Moistened sheets are pressed against the master, and take up enough of the pigment to make a good copy. The ditto machine costs more than mimeos of comparable quality, but cost per page of reproduction is less. Besides the reproduction-range up to 300 copies because no ink is wasted, there is the further advantage that some copies may be run off now and others next week. Ditto is usually in purple (colors are available, as below) and on smooth surfaced paper; this is a specimen of it. Oh, and Laney called Walter A Coslet's spiritduplicating plant a Dittorium, tho Coslet's ditto is actually a Wolber machine.
