| abstract |
A table has a mechanically driven draw bar squeegee mounted thereon to spread ink and other substances in a uniform manner. There is an interchangeable plurality of such squeegees which may be sequentially placed in said table to enable successive layers of different types of materials to be spread, in sequence, over the surface of a paper. This succession of materials includes an isolation layer between successive colors of ink, whereby a mistake on work in progress does not necessarily lead to a final destruction of all previously done work. A feature of the invention is that the pigmented surface of dried ink is not seen through the tint of other material, such as photoresist, for example. Also, a releasable layer may be provided among the successive layers so that a hand proof copy may be transferred, as a decalcomania. |
