470:. A stiff, oily intaglio printing ink is applied to the whole surface of the plate with a rubber brayer, or a small, stiff squeegee, or a rolled tamper. The plate is then gently wiped with tarlatans to remove the excess ink and drive it into the recesses (wells). It is finally wiped with the fatty part of the palm of the hand in quick glancing strokes. This removes all remaining ink from the polished highlights and high points and leaves ink only in the etched recesses. After the edges are cleaned, the plate is placed on the printing bed of an intaglio press. It is covered with a sheet of dampened rag paper and then two to three layers of thin wool blankets. It is then run through the press at high pressure. The high pressure pushes the fibers of the dampened paper into the wells of the plate which then transfers the ink onto the paper thereby creating the impression. The paper is carefully peeled off the plate and placed between blotters and weighted so it will dry flat. The plate can now be re-inked for another impression or it can be cleaned for storage.

controlled, precise way ... This process is an inversion of the traditional photogravure method, where you're etching through a sheet of gelatin, and gradually the gelatin is getting thinner and more acid reaches the plate, so the last thing that's etched are the light tones." Instead, the digital direct-to-plate method requires that the light values be etched first; then the printer is used to lay down a new layer of ink onto the plate between acid baths, masking out the lighter values to protect them from subsequent etches. The initial mask looks like it has barely been printed; the masks grow in density until the plate eventually appears almost completely black.

438:. The ferric chloride migrates through the gelatin, etching the shadows and blacks under the thinnest areas first. The etching progresses through the tonal scale from dark to light as the plate is moved to successively more dilute baths of ferric chloride. The image is etched onto the copperplate by the ferric chloride, creating a gravure plate with tiny "wells" of varying depth to hold ink. The pattern formed by the aquatint grain or the screen exposure creates minute "lands" around which the etching occurs, giving the copperplate the

The process involves a series of exposures of the polymer plate. First, it is exposed under strong light with a random dot screen placed on top of it (called an aquatint screen in fine art printing or a stochastic screen in commercial printing). Next, the plate is exposed to a positive transparency

Once adhered, the fifth stage is to use a hot water bath to remove the paper backing and to wash away the softer, unexposed gelatin. The remaining depth of hardened gelatin is relative to the exposure. This layer of hardened gelatin forms a contoured resist on the copper plate. The resist is dried,

Photogravure registers a wide variety of tones, through the transfer of etching ink from an etched copper plate to special dampened paper run through an etching press. The unique tonal range comes from photogravure's variable depth of etch, that is, the shadows are etched many times deeper than the

After proper drying and curing, the plate can be inked and printed. The dual exposures produce an "etched" polymer plate with many thousands of indentations of varying depth which hold ink, which in turn are transferred as a continuous tone image to a sheet of paper. Depending on the quality, the

In another variation of the traditional process, where the acid baths are increasingly watered down as the process unfolds, the direct-to-plate process begins with a weak bath and is gradually etched in baths which are increasingly acidic.
